Safety Safety Guidelines The following general guidelines, together with the instructions provided throughout this user guide, ensure user safety while operating and maintaining the Eden system. If the system is not operated as specified, the userʹs safety may be compromised. Eden Printer Installation and removal of the Eden printer should only be done by qualified service personnel. The Eden printer should only be operated by persons trained by an Objet customer‐support representative. Service operations should be performed only by personnel who have been instructed in relevant safety precautions. All personnel operating or maintaining the Eden printer should know the location of first aid and emergency equipment and how to use it. Never block access to this equipment. Never attempt to open the main cover of the printer while it is working. Never bypass the interlock safety switch. If the interlock safety switch ever fails, or if servicing is ever necessary while the main cover is open, never stare directly at the UV lamps without glasses that screen out UV radiation. For this purpose, ordinary sunglasses with UV screening are adequate. Never connect the power plug to a socket that does not have a ground (earth) wire, and never disconnect the ground. Doing so may expose the operator to serious danger from electric shock. The power cable should be connected at an easily accessible electric socket near the printer. Never insert screwdrivers, wires, or other objects into the power supply housing. Leave a minimum of 15 centimeters between ventilation openings and walls or other objects. Several parts of the printer remain extremely hot even after it has stopped operating. Avoid touching the main power supply, the UV‐ lamp power supply, UV lamps, and the print heads. Notify co‐workers and those who have access to the Eden system before beginning non‐routine and hazardous work. Report any potential dangers and safety‐related accidents to your safety officer or to other appropriate authorities.
Eden500V/350V/350 User Guide Model and Model and support materials are made of resins. Although precautions Support must be taken when handling resins directly, all model and support Material materials used by the Eden system are handled in sealed cartridges. Normally, operators of the Eden printer should never be directly exposed to dangerous materials. Most of the following recommendations for handling resins apply to the unlikely event of a leak or spill. If this should occur, follow the specific instructions printed on the printing‐material cartridge used. Store cartridges of 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 resin is considered a hazardous material, requiring certain precautions when handling it. To prevent skin irritation, wear protective gloves, if necessary. If there is any chance that model and support materials might splash into the eyes, wear safety goggles. Prolonged direct contact with resins can cause an allergic reaction. To prevent respiratory irritation, ventilate areas where model and support materials are used. The ventilation system should totally replace the air 20 times per hour. Clean 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. Absorbed resin may re‐expose the user when these items are worn again. 2–5 DOC-00500 Rev. F...
Safety First Aid for Working With Resins In general, try to avoid direct contact with uncured resin. If skin or eyes come into contact with resin, wash the area immediately and thoroughly with water, and follow the first‐aid instructions below. Contact with If uncured resin comes in contact with skin, wash the affected area Skin immediately and thoroughly with soap and cool water, then remove contaminated clothing. Pay particular attention to flushing the hair, ears, nose and other parts of the body that are not easily cleaned. Use cool water to prevent skin pores from opening, so that the resin does not easily penetrate the skin. Do not use solvents to clean skin. If large areas of skin have been exposed to resin, or if prolonged contact results in blisters, seek medical attention. Avoid the accidental transfer of resin from the hands to other areas of the body, especially to the eyes. If protective cream was used, do not reapply it until the skin has been completely cleansed. Contact with If uncured resin comes in contact with the eyes, flush immediately with Eyes large amounts of water for 15 minutes and seek medical attention. Avoid sunlight, fluorescent light, and other sources of ultraviolet radiation. The wearing of contact lenses when working near resin is not recommended. If resin splashes into the eyes when contact lenses are worn, immediately remove the lenses and flush the eyes with water. Clean and disinfect the contaminated lenses. Do not wear contact lenses until eye irritation disappears. Ingestion If resin is swallowed, refer to the cartridge label for specific instructions. Seek medical attention immediately.
Eden500V/350V/350 User Guide Waste Disposal Fully cured resins present no special safety or health‐related issues. However, check if local regulations regard cured and partially cured resins as hazardous industrial waste, and comply with all applicable regulations governing their disposal. When removing the waste container from the Eden printer, protective gloves are not required. When directly handling uncured resins, neoprene or nitrile gloves should be worn. When handling cured materials that may not be completely cured on the surface, common latex gloves are adequate. Even if not classified as hazardous industrial waste or otherwise regulated, resin materials must be packaged and disposed of in a manner that prevents human contact with the waste. Therefore, take steps to prevent the contamination of both groundwater and surface water. Empty model‐material and support‐material cartridges are sealed to prevent leakage. Do not attempt to reuse them, and do not puncture them. Discard contaminated clothing, shoes, empty containers, etc., in accordance with any applicable laws and regulations. 2–7 DOC-00500 Rev. F...
Introducing the Eden 3-D Printing System Eden500V/Eden350V/Eden350 Figure 3-1: The 3-D Printer Work Configurations The Eden 3‐D 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 3‐D printer, acts as a job manager that sends production jobs to the printer for production. Figure 3‐2 shows the Eden printer set up in a multi‐client configuration. 3–2 DOC-00500 Rev. F...

The Objet software 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 3‐D printer, and can prioritize and delete jobs, review job history and reprint a job, and so Source Files Eden 3‐D printing systems produce three‐dimensional models designed with most 3‐D CAD tools and with other job‐specific 3‐D applications. Eden systems accept: • STL files • SLC files Eden systems feature the capability of producing both types of model files simultaneously. 3–3 DOC-00500 Rev. F...
Most CAD software can export STL files. The Eden system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass‐producing items. STL files are ASCII (text) files. The content of each 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‐ dimensional contours of the three‐dimensional models. These contour lines are polylines. SLC files are ASCII (text) files that save models as a series of slices. This means that models based on SLC files cannot be orientated; only their scale (size) and position on the build tray can be controlled. For this reason, the model’s orientation must be suitable for production before it is saved as an SLC file. Because of the nature of SLC files, the appearance of models in Objet Studio may be different than the solid‐object images displayed from STL files. Printing Materials Materials used for printing models with Eden printers are made of resins, which are composed of reactive monomers and oligomers. Care must be taken when storing and handling them, both to protect operators and the environment, and to ensure their effectiveness. Signs of premature polymerization in material cartridges may include bulging, leaking, the emission of heat, and unusual odor. Exposure to heat can cause resin to gel in the cartridge. To prevent this, observe the following guidelines when handling and storing Eden modeling and support materials. 3–4 DOC-00500 Rev. F...
Eden500V/350V/350 User Guide Storage Printing materials used with Eden systems are supplied in UV‐proof cartridges. • To ensure product stability, do not allow these materials to come into contact with metal. Plastics made from monomer‐soluble substances (such as polystyrene or polyvinyl chloride) are not suitable for storing Objet printing materials. • When not in use, keep material cartridges tightly sealed to prevent contamination, the effects of exposure to UV radiation, and accidental spillage. • Store material cartridges indoors, in a dry area with adequate ventilation, between 16–27 degrees Celsius (60–81 degrees Fahrenheit). If exposed to heat or flames, cartridges may burst or ignite. • Make sure that material cartridges are stored in accordance with all local regulations and other applicable requirements. Shelf Life Materials used for producing models have a limited shelf life. The expiry date on the label is valid when properly stored in an undamaged, unopened cartridge. Always rotate your stock, so that the cartridge with the earliest date is used first. Light If printing materials are not in their sealed cartridges, make sure to shield them from sunlight and other sources of UV radiation, such as fluorescent and mercury‐vapor lights. Exposure to UV radiation causes an increase in viscosity and, eventually, solidification. 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. •...

Using Objet Studio Model Orientation The orientation of models on the build tray affects how quickly and efficiently they will be produced by the 3‐D printer, where and how much support material is used, and whether or not model parts will have a gloss 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 longest dimension along the X‐axis. Since high‐resolution models are built up, on the Z‐axis, in 16‐micron layers, 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 the left until reaching them. If, on the other hand, the taller sections are positioned on the left of the tray, the print heads only have to scan the model until printing these sections—once the lower parts have been completed. Therefore, you should position the taller side of the model, when possible, on the left. The following rules are based on the fact that support material is not required on the top of the printed model.
In practice, the Eden 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.
After you manually manipulate an object with the mouse, its new properties are displayed in the Transform tab of the Entity Properties dialog box.

Handling Completed Trays After you have properly placed all objects on the build tray, you save the tray as an otf file, which is sent to the 3‐D 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 Eden 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.

With two of the options, the print block is flushed with the new model material. With the third option, the print block is flushed with cleaning fluid before it is filled with the new model material. Flushing the block with model material: • Short Cycle. During this cycle, which takes about 30 minutes, the pump purges the model material from the print block, then flushes the system with the new material. Since traces of the previous material may be present in the first models printed with the new material, this cycle is usually acceptable when replacing a light‐colored model material with a darker material (such as TangoBlack™ or VeroBlack™), or if the color of the printed models is unimportant. • Double Short Cycle. During this cycle, which takes about 50 minutes, the wizard cleans the feed tubes and print block more thoroughly by flushing the system twice with the new material. This cycle is used when replacing a dark‐colored model material (such as TangoBlack or VeroBlack) with a lighter material. Flushing the block with cleaning fluid: • Long Cycle. During this cycle, which takes about 60 minutes, the wizard cleans the tube and print block very thoroughly by flushing the system with cleaning fluid before filling the block with the new material. This cycle is used when replacing a dark‐colored model material (such as TangoBlack or VeroBlack) with a lighter material.

Operating & Maintaining the Eden 3-D Printer The waste container consists of a plastic container inside a cardboard box. You typically dispose of the entire waste container—including the box. Therefore, you must assemble a new box and insert a new plastic container before you can install it in the printer. Replacement boxes, plastic containers, and sealing caps are supplied in the Eden printer start-up and preventive-maintenance kits. To prepare a new waste container: 1. Assemble the cardboard box, making sure to punch out the perforated sections. 2. Place a new plastic container into the box. Note: Do not close the box until you connect the waste drain tube from the printer (see below).

3. Place the models on a flat surface, and cover them with a cardboard box or paper hood. This allows the models to cool slowly and evenly. 4. Let the models cool for several hours. Removing the Support Material After printed models have cooled, the support material must be removed. This can be done by different methods, depending on the size of the model, how delicate it is, the amount and location of the support material, and other factors. Use the following methods as a guide, and adapt them (or a combination of them) for finishing the models you are handling. Removing Excess Support Material by Hand While wearing protective gloves, break away excess support material on the outside of the model. For delicate models, use a toothpick, pin or small brush after dipping the model in water. Removing Support Material with Water Pressure For most models, the most efficient way to remove support material is by using a high‐pressure water jet. One suitable system is the Balco WaterJet cleaning unit, shown in figure 8‐1 on page 8‐3. This device is marketed by Objet. 8–2 DOC-00500 Rev. F...
Eden500V/350V/350 User Guide Figure 8-1: Balco WaterJet Cleaning Unit To clean a model using this device, you place it in the chamber, and you manipulate it and the jet using the built‐in, waterproof sleeves. A pump turns ordinary tap water into a high‐pressure jet, and a wiper keeps the window clear. Use caution when cleaning delicate models with high-pressure water systems. Removing Support Material with Caustic Soda Soak models in a 2‐percent solution of caustic soda (sodium hydroxide) to remove support material from difficult‐to‐reach areas and to give the 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.
