12.13 nGen
NGen was developed by Eastman Chemical Company and colorFabb. It is very similar to
classic PETG. It does not contain styrene.
Advantages
Disadvantages
Smooth surface
Brittle
Good layer adhesion
Slight warping
●
Nozzle temperature:
240 °C
●
Bed temperature:
80 - 100 °C (a larger object requires a higher temperature)
● Heatbed:
Make sure the surface is clean, as described in
chapter. Apply a thin layer of glue stick when using the Smooth PEI
sheet.
12.14 PP
Polypropylene has very good mechanical properties, is partially elastic, can withstand higher
temperatures than ABS or PLA and is resistant to many chemicals.
Advantages
Disadvantages
Ductile
Tendency to warp
Partially elastic
Bad adhesion to the heatbed
Temperature resistance
●
Nozzle temperature:
210 -230 °C
●
Bed temperature:
95 - 100 °C.
●
Heatbed:
Do not print on the Textured PEI powder coated sheet. Use PP transparent
