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. 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. 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 - 220 C. POM can be printed on a heated bed plate 100 C - 130 C. Acetal does not adhere well to any of the typical 3D printer bed surfaces. Using wood or cellulose based platforms to print on is the best alternative. A cheap and quick alternative is to use a thick resume or sketch paper, roughly 80 pound weight. Glue down the paper with Elmer's glue stick on top of your printer bed which is typically metal or borosilicate glass. Some users print using blue tape covered with hairspray. Not all blue tape and hairspray are the same. If you have a heated chamber, then please remember to pre-heat your chamber to reduce warping. Printing in an enclosed chamber will help with delamination. Please keep Acetal away from moisture and always keep filament in an airtight container with a desiccant. Net weight = 1 kg or 2.2 lbs Printing temperature : 210 C - 220 C Bed temperature : 100 C - 130 C Print speeds : 30mm/s Great strength and low friction Print on a heated bed Use in well ventilated areas or ventilated systems Size Options 1.75mm 3mm (2.85mm) Please note that Acetal degrades when overheated and may give small amounts of formaldehyde gas. Do not keep Acetal heated above 230 C. Please always use in a well ventilated area or in a ventilation system. Decomposition of the material depends on the length of time it is exposed to elevated temperatures. At typical print temperatures of C, decomposition is not significant until after 30 minutes. At melt temperatures, acetal is incompatible with halogenated polymers and can cause spontaneous formaldehyde gas formation. Print using an all metal hotend.

High quality acetal 3D printer filament comes vacuum sealed with a desiccant pack,POM filament temperatures - hot end nozzle: 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
