Acetal POM 1Kg


  • £45.00

Polyoxymethylene (POM) filament is also known as Acetal or Polyacetal. The company DuPont uses the trade name Delrin for Acetal Resin. It is a commonly used thermoplastic to engineer specific parts. Acetal filament has high stiffness, low friction and excellent wear resistance. The filament has good chemical and heat resistance. Because of it's low friction, POM is routinely used as gear wheels, ball bearings, etc.

The recommended print temperature is between 210 - 225°C. Please note that Acetal degrades when overheated and may give off small amounts of formaldehyde gas. Do not keep Acetal heated above 230°C. Therefore, please always use in a well ventilated area or in a ventilation system. Please keep Acetal away from moisture and always keep filament in an airtight container with a desiccant. POM can be printed on a heated bed plate ~130°C covered in tape. Use hairspray or print glue on top of the blue tape for even better results. Some users prefer wood or cellulose based platforms to print on such as high density cardboard. If you have a heated chamber, then please remember to pre-heat your chamber to reduce warping.

Important Notes

3D printing with Acetal is very challenging so please note:-
i. it requires a dual-head filament based 3D printer, in order to apply a mixed material as the raft;
ii. requires high temperature printing, which runs the small risk of the Acetal catching fire - so the printer should not be left unattended;
iii. there can be technical issues adhering the base layers of the geometry; so this requires experience;
iv. the parts can "warp"; so some geometry may be very challenging;
v. Acetal degrades when overheated and may give off small amounts of formaldehyde gas; so strictly controlled ventilation is required.
