Polyoxymethylene (POM) filament is also known as Acetal or Polyacetal. It is a commonly used thermoplastic to engineer specific parts. Acetal filament has high stiffness, low friction, and excellent wear resistance. It has good elastic resilience and great dimensional stability. The filament has good chemical and heat resistance. Because of it’s low friction, POM is routinely used as gear wheels, ball bearings, etc. It has high impact resistance, which is one of the reasons the M16 rifle’s stock is made out of POM.
The recommended print temperature is between 210°C – 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 blue tape. Use hairspray 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.
