Gizmo Dorks 1.75mm Acetal Delrin Filament POM 1kg / 2.2lbs for 3D Printers, Black

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.Extrusion Settings - The recommended print temperature is between 210 C - 220 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.Print Bed - The hardest part to printing acetal filament is getting the first layer to adhere. POM filament does not typically adhere to conventional 3D print bed surfaces. Some users have found success with blue painters tape with hairspray on top (different blue tapes and hairspray brands have different results). However, POM filament prefers wood or cellulose based platforms. Thicker weight paper such as resume paper or sketch paper can be glued to borosilicate glass with Elmer's glue stick. A heated bed should be used to at least 100 - 110 C.Special Note - POM filament warps a lot. An enclosed chamber should be used to retain heat for better layer adhesion and reduce delamination issues. Please keep acetal away from moisture and always keep filament in an airtight container with a desiccant.Extrusion Temperature: 210 - 220 CHeated Bed: 110 CPrint speeds : 30mm/sDiameter: 1.75mm +/- 0.03mmNet Weight: 1 kilogramAvailable Colors in 200g Size: Black and White

• High quality acetal 3D printer filament comes vacuum sealed with a desiccant pack
• POM filament temperatures - hot end nozzle: 210 - 220 C; bed temperature: 110 C
• Acetal printed parts have great strength and low friction, ideal for impact parts or gear wheels
• Acetal warps during the print so an enclosed printer (can be simple cardboard over printer) and a heated bed are recommended
• Only use in well ventilated areas or ventilated systems
