Spooler Manual 20
Polymers Guide
In this section you can find some information about the plastics you can extrude with Felfil
System.
When using commercial pellets, rely on the maker’s identification of the type of plastic.
When using recycled plastic, check the markings on the item(s) to determine which type of
plastic you are using.
Do not mix types of plastic, as this may affect processing times, both in the extruder and in
the printer.
The following is a table of general processing temperatures. Notice that the processing tem-
perature may not be the same as the melt temperature. Temperatures will vary based on:
humidity, ambient temperature and chemical composition of the polymers.
NOTE: The temperature ranges in the chart are approximate. It will require some trial and error
to determine the right processing temperatures. Keep notes of actual temperature settings
with different types of plastics, along with other operational notes, to develop a procedure that
works well in your situation.
