Objet260 Connex User Guide Model and Model and support materials are made of chemical substances. Although Support precautions must be taken when handling these materials directly, all Materials model and support materials used by the Objet260 Connex system are handled in sealed cartridges. Normally, operators of the printer should never be directly exposed to hazardous materials. In the unlikely event of a leak or spill, follow the instructions that are included with the printing‐ material cartridge used. Store model and support materials indoors, in a dry area with adequate ventilation, between 16‐27 degrees Celsius (60‐81 degrees Fahrenheit). Never expose them to flames, heat, sparks, or direct sunlight. Keep model and support materials away from areas where food and drink are stored, prepared and consumed. Uncured printing material is considered a hazardous substance, requiring certain precautions when directly handling it. To prevent skin irritation, wear neoprene or nitrile gloves. If there is any chance that model and support materials might splash into the eyes, wear safety goggles. Prolonged direct contact with printing materials can cause an allergic reaction. When handling UV‐cured models that may not be completely cured on the surface, common latex gloves are adequate. To prevent respiratory irritation, ventilate areas where model and support materials are used. If the printer is not equipped with an exhaust duct, the room ventilation system should replace the air at least 20 times per hour. Clean up model‐material and support‐material spills with disposable towels or other absorbent, non‐reusable material, such as sawdust or activated charcoal. Rinse the spill area with denatured or isopropyl alcohol (IPA), followed by soap and water. Dispose of the absorbent material in accordance with local regulations. Do not wash contaminated clothing at home; clothing should be professionally laundered. Dispose of contaminated shoes, belts and other leather items in ...
Safety First Aid for Working with Printing Materials In general, try to avoid direct contact with uncured printing material. If skin or eyes come into contact with it, wash the area immediately and thoroughly with water, and follow these first‐aid instructions. The Material Safety Data Sheet (MSDS) that accompanies printing materials contains important safety information. Keep this in an accessible place where these materials are used and stored. Contact with If uncured printing material comes in contact with skin, wash the affected ...
Objet260 Connex User Guide Waste Disposal Fully cured printed models can be disposed of as ordinary office trash. However, special care is required when handling printer waste (uncured printing material). Printing Materials When removing the waste container from the Objet260 Connex printer, wear neoprene or nitrile gloves. To prevent liquid waste from splashing into the eyes, wear safety goggles. Liquid waste from the Objet260 Connex printer is classified as hazardous industrial waste. Therefore, printing‐material waste must be packaged and disposed of in a manner that prevents human contact with it and contamination of water sources. Empty model‐material and support‐material cartridges contain residue of their contents. Some leakage of this residue may occur through the broken cartridge seal. Therefore, handle and store empty cartridges with care. Do not attempt to reuse empty cartridges, and do not puncture them. Dispose of used cartridges and waste containers in accordance with local regulations. Discard contaminated clothing, shoes, empty containers, etc., in accordance with any applicable regulations. UV Lamps UV lamps used by the printer to cure printing materials contain a small amount of mercury, and are considered “Universal Waste.” Recycle or discard used lamps in accordance with applicable regulations. Broken lamps: After ventilating the area, use protective gloves and carefully remove spilled mercury with a method that prevents the generation of mercury vapor, such as a syringe, packing tape or paper. Place the broken lamp, mercury and contaminated materials in an air‐tight, non‐metallic container. Dispose of the container in accordance with applicable regulations. 2–7...
Introducing the Objet260 Connex 3D Printing System Welcome to Connex The advanced capabilities of Connex™ 3D printing systems are made possible by technology specially developed by Stratasys for printing models simultaneously with different model materials. With Connex printers, you can achieve the following results when printing 3D models: • You can prepare objects for printing with two designated model materials and then print them at the same time. This enables you to assign specific mechanical and color properties to objects. • You can print objects with combinations of basic materials (digital materials), enabling you to choose from a wide range of possible mechanical properties—from flexible to rigid. • You can print parts of the same model—simultaneously—with different materials (or material combinations). • You can print objects that have a “coating” made from a different material than the main part of the object. Because Connex printers can be loaded with different materials, you can streamline and economize the process of producing models: • Printing models made from different materials on the same build tray (“mixed tray”), in the same print job, eliminates the time‐consuming need and expense of loading another material, flushing the system, and sending a separate job to be printed. • You can quickly alternate printing jobs using either of the model materials loaded, or material combinations—again, without the need and expense of replacing materials.
Objet260 Connex User Guide Work Configurations The Objet260 Connex 3D printing system can be set up as a single‐station system or as a multi‐station system. When connected to a local computer network, the system can serve multiple users. In such configurations, each user workstation (client) prepares files with Objet Studio software for production. A server (host), typically next to the 3D printer, acts as a job manager that sends production jobs to the printer for production. Figure 3‐2 shows the Objet260 Connex printer set up in a multi‐client configuration. Client workstations Printer server KVM switch Printer workstation Printer Figure 3-2: Multi-client network configuration When installing Objet Studio, you choose whether to install it as a client station or as a master station (server or standalone station). Objet Studio arranges the jobs it receives according to their priorities, model‐material type, and other factors. In multi‐workstation configurations, the operator of the server—typically the production administrator—has total control over the jobs sent to the 3D printer, and can prioritize and delete jobs, review job history and reprint a job, and so 3–3 DOC-33040 Rev. A...
Introducing the Objet260 Connex 3D Printing System Source Files Objet 3D printing systems produce three‐dimensional models designed with most 3D CAD tools and with other job‐specific 3D applications. Objet260 Connex systems accept: • STL Files • SLC Files Objet260 Connex systems feature the capability of producing different types of model files simultaneously. STL Files STL is short for Standard Triangulation Language. This language views any object as a collection of surfaces, and describes each surface of the object as a collection of triangles. For example, a square can be described as two triangles; a cube (six squares) as 12 triangles. Curved surfaces need more triangles to describe them. The higher the tolerance (for smooth surfaces), the more triangles are needed. The result is that high‐quality object descriptions mean very heavy files. Most CAD software can export STL files. The Objet260 Connex system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass‐producing items. STL files can be ASCII (text) files or binary files. The content of the ASCII file begins with “solid” and ends with “end‐solid” (both lower case). Between these keywords is a list of the triangles that describes the faces of the solid model. Each triangle defines a single normal vector directed away from the solid’s surface, followed by its X‐Y‐Z coordinates. These are expressed as Cartesian coordinates and are floating‐point values. The coordinates of all triangles should be positive and should fall within the volume of the model. SLC Files SLC is short for Stereo‐Lithography Contour. SLC files describe two‐...

Introducing the Objet260 Connex 3D Printing System Printing Materials Objet260 Connex printers produce models by jetting thin layers of printing materials on the build tray, until the complete model is formed. Two types of material are used in this process: • Model material—which makes up the finished model • Support material—which fills gaps and spaces in the model during printing, and is removed after printing For up-to-date information about PolyJet printing materials and their properties, go to http://www.stratasys.com/materials/polyjet. Storage Materials used for printing models with Objet260 Connex printers are made of resins, which are composed of reactive monomers and oligomers. Although printing materials are supplied in sealed, UV‐proof cartridges, care must be taken when storing and handling them. Follow these guidelines to protect operators and the environment, and to ensure optimum results. • To ensure product stability, do not allow these materials to come into contact with metal. Plastics made from monomer‐soluble substances ...
Objet260 Connex User Guide Safety Before being cured, resins are hazardous materials. To prevent possible Considerations health hazards, follow these precautions regarding printing materials: • Do not expose to flames, heat or sparks. • Prevent contact with skin and eyes. • Ventilate areas where they are handled. • Keep them separate from food and drink. Cured plastic parts, however, are safe. They can be handled and stored without precautions. You can find more safety information about resins in “Safety Guidelines” on page 2-4, and “First Aid for Working with Printing Materials” on page 2-6.

4. In the file format option, choose binary or ASCII. (Both binary and ASCII formats can be used in Objet Studio. However, binary files are smaller, so this option is recommended.) 5. Click or Save After converting the model files, it is recommended that you check them for ® defects in an STL‐repair application (such as Magics™, by Materialise ) before opening them in Objet Studio and producing the model. For more information, search for “CAD to STL” on www.stratasys.com. Converting When converting files to SLC format, it is recommended that you set a layer CAD Files to thickness of 15 microns (0.015 mm). Since SLC files cannot be orientated in SLC Format Objet Studio, it is important that models are properly orientated before being saved as SLC files. Considerations for suitable model orientation are explained in “Model Orientation” on page 5‐28. 3–9 DOC-33040 Rev. A...

Objet260 Connex User Guide Preparing Models for Production Model preparation involves the following basic steps: 1. Place objects or assemblies on the build tray. 2. If necessary, manipulate the object’s orientation and position. 3. Select the materials and model finish. Just as Objet260 Connex printers can produce different models on the build tray using different materials, you can produce components of a model with different materials. To do this, each part of the model must be a separate stl file. If the model’s component parts were not saved in the CAD software as separate stl files, you can use Objet Studio to separate the model into component parts. (This is described in “Splitting Objects into Components” on page 19 and in “Dividing Objects” on page 53.) OBJDF Files: An objdf file describes both the geometry of a single object and the Overview materials, and finish required to print it. The objdf file can represent an object that is a single stl file, or an object assembled from component stl files. Objet Studio enables you to split an stl file representing a complex object into an assembly of component stl files, and save the assembly as an objdf file. Each part (stl file) described by the objdf file can have its own model‐ material characteristic, so that the Objet260 Connex printer produces the component parts from specific materials. Another use for objdf files is for saving a group of separate objects on the build tray as one unit, together with their relative positions and materials. This is especially useful for producing models in the future with the same materials. In fact, when you save objdf files, you specify materials for ...

Objet260 Connex User Guide Opening objdf Files Before placing objdf files on the build tray, Objet Studio must extract the component stl files together with information about their relative position and model materials. To do this, Objet Studio creates a folder with the same name as the objdf file, in the same location. If you are opening an objdf file, the Insert dialog box also includes a Materials field that shows the object’s printing material assignment (see below). Figure 5-14: Insert dialog box (objdf file)
Using Objet Studio Opening Objet You can open trays that were saved as objtf files.

Objet260 Connex User Guide Copying and If you need to duplicate objects on the build tray, you can insert the same Pasting object from its file more than once. An easier way, however, is to copy and Objects paste the object. You can copy objects from the build tray or the model tree—individual or multiple parts or assemblies. The objects copied remain in the Windows clipboard until you paste them onto the build tray. You can also copy objects from one tray and paste them onto another, in the same way as you copy text from one document and paste it into another one. However, Objet Studio allows only one tray to be open at a time. For each build tray you need to work with (at the same time), you must open a separate Objet Studio window, by running the application again (from the Windows Start menu). Having multiple Objet Studio windows open can be convenient when you need to manipulate or configure objects before inserting them in your production build tray.
Using Objet Studio Selecting To manipulate an object on the build tray or assign characteristics to it Objects (model material, building style etc.), you must first select the object. You select an object by clicking it, either on the tray or in the model tree. Its image on the build tray changes color (to light blue, by default) and its name is highlighted in the model tree. You can select multiple objects by drawing a box around them with the mouse cursor, or by pressing the Ctrl or keys while clicking additional objects. Shift Alternatively, select or de‐select objects using the following Edit menu commands: • Select All • Invert Selection • Undo Select object Figure 5-19: Edit menu Sometimes, you need to select individual elements of an assembly. Other times, you need to select the entire assembly. The Selection icon displayed on the ribbon determines what will be selected when you click on the model: or To change the selection action: 1.
Objet260 Connex User Guide Splitting You can convert a complex object to an assembly of component parts. To do Objects into so, you split the stl file that represents the object into a group of separate stl Components files, each one representing a component. (This is referred to in the Objet Studio interface as separating the object into shells.) You can then assign a model material to each stl file, and you can save the newly‐created assembly as an objdf file. To split an object into an assembly of component parts: 1. If the object is not displayed, place it on the build tray by inserting its stl file (see “Placing Objects on the Build Tray” on page 10). The object appears—on the build tray and in the model tree pane—as a single part. It is assigned, by default, the “primary” model material. (If Objet Studio is configured with a secondary material, you can assign it—or a digital material—to the entire object. This is explained in “Model‐Material Settings” on page 20.) Figure 5-21: Object placed on the build tray from a single stl file Note: There is no need to resize or arrange the object on the build tray at this time.
Using Objet Studio The object appears—on the build tray and in the model tree—as an assembly of parts (“shells”). You can assign each part a different model material (This is explained in “Model‐Material Settings” on page 20). Figure 5-23: Object after being converted to an assembly of component parts Model-Material Before placing objects on the build tray in Objet Studio, you should pay Settings attention to the material selection settings on the Tray Settings ribbon. Figure 5-24: Material selection settings • By default, the material selection settings on the ribbon correspond to the two model cartridges loaded in the printer. • The materials displayed are basic model materials. These materials can later be combined to create digital materials (see “Digital Materials” on page 22). • The material displayed on the top (VeroBlack, in the figure above) is considered the primary model material (“Model‐1”). It is assigned to objects that do not have a material assignment when you place them on the build tray. For example, since stl files do not contain information ...

To print this object, you have the following options: Instead of printing it on the same build tray, print the new object as a separate job. Change the materials assigned to objects on the build tray to match those assigned to the new object (see “Changing the Model Material” and “Assigning a Model Material to Objects,” below). Change the materials assigned to the new object before inserting it, so there is no conflict with the settings on the Tray Settings ribbon. To change the materials assigned to an object before inserting it: 1. Open another Objet Studio window, by running the application from the Windows Start menu. 2. Insert the new object (objdf file) into the empty build tray. 3. Change the material selection settings on the Tray Settings ribbon to those used on the other build tray. 4.

Using Objet Studio Digital When two different model materials appear on the ribbon, you can produce Materials objects from either material or from a combination of them—digital materials. Different pairs of model materials enable you to print objects using unique digital materials. Certain digital materials can produce objects with different shades of color. Combinations of model materials that have different mechanical properties result in digital materials with unique characteristics. To view the digital materials available for printing objects (using two basic model materials): 1. Make sure that you have selected the appropriate model materials, and that is selected.

Using Objet Studio Positioning Objects on the Build Tray To produce models efficiently and with the required finish, it is important to carefully position objects on the build tray. Objet Studio supports the automatic positioning of objects. However, you should check to make sure that the objects are orientated optimally for your needs, according to the considerations explained in “Model Orientation” on page 28. Two things that affect the positioning of objects on the build tray are orientation and placement. You can let Objet Studio determine the optimum orientation and position, or you can control them. Automatic By default, Objet Studio automatically orients objects, when placed on the Orientation build tray, for the shortest printing time. (You can later change the orientation manually.) However, you can cancel automatic orientation when placing an object on the build tray. To place an object on the build tray without automatic orientation: In the Insert dialog box, make sure Orient Automatically is not selected. Figure 5-33: Orient Automatically option disabled You can change the default setting, so that automatic orientation is not applied unless you select the Orient Automatically check box each time you place an object on the build tray.
Objet260 Connex User Guide Automatic After placing several objects on the build tray, you can let Objet Studio Placement arrange them before printing. This ensures that the objects are positioned properly, and that they will be printed in the shortest time and with a minimum of material. To automatically arrange objects on the build tray: On the Tray Settings ribbon, click or— From the Tools menu, select Automatic Placement The effects of automatic positioning are shown in the figures below. Figure 5-34: Tray before objects are properly arranged Figure 5-35: Tray arrangement after applying Automatic Placement...
Using Objet Studio Manual You can change the position of objects on the build tray—even if they were Positioning inserted with the Orient Automatically option. Considerations for positioning objects are presented in “Model Orientation,” below. Tools for changing the position of objects are presented in “Manipulating Objects on the Build Tray” on page 29. Model Orientation The orientation of models on the build tray affects how quickly and efficiently they will be produced by the 3D printer, where and how much support material is used, and whether or not model parts will have a glossy finish. Therefore, you should consider a variety of factors when deciding how to place models on the tray, using the following positioning rules. X-Y-Z Rule This rule considers a modelʹs outer dimensions. Since the print heads move back and forth along the X‐axis, the printing time along this axis is relatively short, compared to printing time along the Y‐axis and Z‐axis. From this point of view, it is advisable to place the objectʹs largest dimension along the X‐axis. Any surfaces that come into contact with support materials become matte. Since models are built up, on the Z‐axis, in 16‐ or 30‐micron layers (according to the printing mode), it is very time‐consuming to print a tall object. From this point of view, it is advisable to place the objectʹs smallest dimension along the Z‐axis. Since the print heads measure about 2 inches (5 centimeters) on the Y‐axis, models measuring less than this (on the Y‐axis) are printed in one pass. From this point of view, it is advisable to place the objectʹs intermediate dimension along the Y‐axis. Tall-Left Rule This rule considers models where, after being orientated on the build tray according to other considerations, one side is taller than the other. Since the print heads move along the X‐axis from left to right, taller sections on the right require the print heads to scan unnecessarily from ...
In practice, the Objet260 Connex system prints all models on the build tray on a one-millimeter bed of support material. The importance of positioning objects directly on the build tray with Objet Studio is to correctly display the objects on the screen.

Objet260 Connex User Guide Handling Completed Trays After you have properly placed all objects on the build tray, you save the tray as an objtf file, which is sent to the 3D printer for production. But before saving the tray, you can check that there would be no problem producing it. You can also calculate how much material would be consumed during production and how much time this would take. Tray Validation Before sending a job to the printer for production, you should check that the tray is “valid” and can be printed. Note: Because of the unique characteristics of each type of modeling material, make sure that the correct material is selected before performing Tray Validation.
Using Objet Studio Production Objet Studio enables you to calculate the time and material resources Estimates needed for producing trays before sending them to the printer. The time it takes Objet Studio to perform this calculation depends on the number of objects on the tray and their complexity.

Objet260 Connex User Guide Printing Modes Objet260 Connex printers can build models using three possible printing modes. HQ (High Quality) Mode— • Models are printed in 16‐micron layers, resulting in smooth surfaces, suitable for producing fine‐detailed and delicate items. • Almost twice as much time is required to print most trays, compared to the High Speed setting. • This setting is only available when model material can be used in four print heads, in single‐material printing. Single-material printing: All print heads print models without regard to the source of the model material. This happens in the following situations: All print heads are supplied with one model material.

Using Objet Studio If you allow the use of substitute model materials, the printer will use different materials whose characteristics (strength, flexibility, etc.) are similar to those of the material you assigned to the object when designing the build tray—under the following conditions: • The material you assigned is not installed in the printer at the time of printing. In this case, the tray is printed with either one or two substitute materials (depending on the materials installed in the printer at the time of printing). If possible, High Speed mode is used. • In addition to the material you selected, there is another (similar) material installed in the printer at the time of printing. In this case, High Speed mode is used, by printing with a mixture of the two materials (as if they were the same material). 4.

Objet260 Connex User Guide “Hollow”— Many objects placed on the tray from stl files are “solid.” This means that, Filling Models when printed, the model will be completely filled with model material. with Support Often, especially with large objects, this is unnecessary. Instead, the model Material can be filled with support material, which is less costly. It is also advisable to fill models with support material when preparing them for investment casting, since this material burns off more quickly during the process of making the cast. Objet Studio enables you to print objects on the tray with an outer shell of model material and a center filled with support material. When using this feature, called “Hollow,” the thickness of the shell should be no less than 0.5 millimeters. To use the Hollow feature: 1.

Operating & Maintaining the Objet260 Connex 3D Printer Loading Model and Support Cartridges Objet260 Connex printers use two cartridges of Model material and two cartridges of Support material, each weighing 3.6 kilograms when full. A graphical representation of the cartridges loaded and their current weight appears in the printer interface (see figure 6‐3). The printer uses RFID technology to automatically identify cartridges of printing material. For this purpose, an RFID module is part of the printer hardware.
• The print block is heated. • The UV lamps are powered and they warm up. When printing begins, Objet Studio sends seven slices to the printer‐control application. This is the standard buffer between Objet Studio and the printer. As each slice is printed, another slice is sent to the printer. Depending on the size of the model(s) to be produced, printing can take between several hours to several days. As long as there is enough Model and Support material in the supply cartridges, printing proceeds automatically until the job is finished. During printing, the server computer must remain on and it must communicate with the Objet260 Connex printer. Do not log-off Windows until printing is finished. 6–5 DOC-33040 Rev. A...

Objet260 Connex User Guide Resuming Production After Printing has Stopped If the printing process is interrupted, Objet Studio stops sending slices to the printer. This can happen, for example, if the printing material runs out in the middle of a print job, and you don’t replace the empty cartridge immediately. After the printer changes to Standby or Idle mode, you need to resume printing from the Job Manager screen of Objet Studio. After printing stops, the printer goes into Standby mode, when heating of print heads is reduced. About 10 hours later, the printer goes into Idle mode, when heating of print heads is stopped.
Page 130
Operating & Maintaining the Objet260 Connex 3D Printer You cannot continue printing the model if: • The number of the last slice printed does not appear in the printer interface, even if the server computer displays the Continue from Slice confirmation dialog box. • There was a relatively long interruption in printing, even if the “last slice” and “continue from slice” indicators are correct. The part of the model already printed may deform or shrink, and there might be a visible difference between it and the newly printed part. The effects of a printing stoppage on a model depend on the model size and structure, Model material used, ambient temperature and the length of the stoppage. If you cannot continue printing: 1. Cancel the print job in the Job Manager screen. 2. Remove the partially printed model from the build tray. 3. Restart the job from the Job Manager screen (in Objet Studio). You can stop and later resume printing from either the printer interface or from the Job Manager screen of Objet Studio.
Objet260 Connex User Guide Changing the Printing Material Before producing models using a different type of printing material than is currently installed, run the Material Replacement wizard to flush the print block and feed tubes. You should carefully plan printing models with different Model materials to avoid unnecessary waste of the materials currently loaded. The amount of material flushed depends on the flushing cycle chosen and if you are replacing one or both Model cartridges.

This cycle can be used when replacing a light‐colored Model material with a darker material (such as TangoBlack™ or VeroBlack™), or if the exact color of the printed models (in the first print jobs) is unimportant. The wizard flushes the system with the minimum amount of material needed to ensure that models have the mechanical properties of the new material. • Efficiency. This option is adequate, in almost all situations, for printing models with uniform and accurate color. It is recommended because it can potentially save 25 to 75 percent of the material used to flush out the old material, compared to the High Performance cycle.

Carefully inspect the test paper to see if there are missing lines. Too many missing lines, especially if they are in the same area, indicates that the quality of printing when producing models will be poor. If this is the case, see “Improving Print Quality,” below. Note: Acceptable model quality is subjective, and depends on the type and scale (size) of the models produced.

To ensure optimum curing of models during printing, a UV Lamps pop‐up message reminds you to test the lamps and calibrate their effective UV radiation after every 300 hours of printing. You do this by running the UV Calibration Wizard. To measure the UV radiation, you need: • Stratasys TOL‐03005‐S (UV sensor and cable, supplied with the printer) or— • a stand‐alone UV radiation meter, approved for use with the printer The wizard compares the measured radiation to the recommended radiation level for each of the lamps, at each printing mode—High Speed, High Quality and Digital Material. When calibrating the lamps, the wizard attempts to adjust the radiation level, if necessary. • If the reading is within the acceptable range, the wizard continues to the next phase. • If further adjustment is necessary, the current phase is repeated. • If the UV radiation is too low to be properly adjusted, the wizard continues to the next phase, but the final wizard screen indicates that the lamp’s radiation for the printing mode is unacceptable. Before testing and calibrating the UV lamps: Make sure the glass lens on each of the UV lamps is clean.

Handling Printed Models Removing Models After Printing After printing models, you should allow them to cool as much as possible before handling them. If additional models do not have to be produced on the printer, it is best to let the printed models cool in the printer, with the cover closed, as long as possible. If the printer must be used to produce additional models as soon as possible: 1. Let the printed models cool on the build tray for at least 10 minutes. 2. Very carefully, remove the models from the tray with a scraper or spatula (supplied in the tool kit), taking care not to pry or bend the model. WARNING: Wear protective gloves when handling printed models before they are washed. 3.

Soak models in a 1‐percent solution of caustic soda (sodium hydroxide) to Removing Support Material with remove support material from difficult‐to‐reach areas and to give the Caustic Soda model a smooth, clean finish. The amount of time you soak the model in the solution depends on how delicate it is and how much support material needs to be removed, but it is typically between half‐an‐hour and several hours. In any case, you should remove as much support material as possible before the caustic soda treatment, and rinse the model thoroughly (with a water jet) afterwards. WARNING: Caustic soda may cause chemical burns, scarring and blindness.
• Arrange the models with enough space between them to allow light to reach all sides of each model. • Verify that the ambient temperature around the models is approximately 40 ºC (104 ºF). Higher temperatures may cause model distortion; lower temperatures may not produce satisfactory results. When using desk lamps, you can achieve the required temperature by positioning the lamps approximately 10 cm (4 in.) above the models. • Inspect the models after six hours of treatment. For parts with a matte finish, this should be enough. Polish and lacquer the parts. For parts with a glossy finish, continue the photobleaching treatment for up to 18 hours more. In Stratasys laboratories, there was a tint reduction of approximately 70% within six hours. After 24 hours, tint was reduced by approximately 90%.
