Tips and tricks

When post-processing PLA, use wet sanding to achieve a perfectly smooth surface. Without water,
you'll quickly start heating the plastic by friction - the object can melt locally. PLA is only soluble
in chemicals like chloroform or hot benzene. The preferred option for connecting multiple parts is
superglue or acetone.
Nozzle temperature: 215 °C
Bed temperature: 50 - 60 °C
Heatbed: Make sure the surface is clean, as described in 10.1 Flexible steel sheet surface preparation

9.2 PET/PETG
PETG is another commonly used material for 3D printing. It is a great choice for printing
mechanical components. Compared to PLA, it has higher temperature resistance, is more
ductile and therefore less brittle. Due to its low thermal expansion it holds well on the heatbed
and does not warp. Printing with it is almost as easy as with PLA. But unlike PLA, it can offer better
mechanical properties. Parts for our printers are printed from PETG!
