Verbatim Primalloy 3D Filament PrimalloyTM is a soft rubber material with outstanding heat, oil and abrasion resistance and mechanical strength.It is a high performance polyester based thermoplastic elastomer (TPE).Exceptional diameter consistency providing the best possible homogeneous wire structure for smooth operation.Manufactured in Japan to very tight tolerances from the highest quality materials to ensure consistent feeding and stable prints.PrimalloyTM is a registered trademark of Mitsubishi Chemical Corporation.All filament is delivered in a vacuum bag, with desiccant, wound onto a bespoke spool.2 year limited warranty.Not food safe Usage Recommended for use in commonly available fused filament fabrication (FFF) 3D printersPrint only in a well-ventilated or hooded work areaBest results obtained with printers having a heated platform (40-50 C)The extruded material adheres best to a build platform that has been covered with Polyimide Tape (see also KaptonTM tape)Keep material sealed until ready for useTo control moisture content, return any partially consumed reel to a sealed, air-tight bag that contains a desiccantTo prevent layer drooping, apply forced air cooling on object as it buildsTo prevent feed jams, apply slow print speeds (30 mm/s) and turn off retraction. Avoid excessive pressure in the pinch feederDue to its flexibility and resultant buckling risk, this filament is not recommended for printers with significant distance (e.g. >15 mm) between pinch feeder and hot end Process temperature 210 - 235 C Material Net Weight 0.5 kg Filament Length 190m Density 1.08 1.10 g/cm3 Tensile Yield (JIS K 7113) 14 MPa Elongation (JIS K 7113) 990 %Melting Point 175 to 195 C Melt Flow Index at 230 C, 21.1N 45 g/(10 minutes) Durometer Hardness D (JIS K 6253) 33 Note Quality Advice: To maintain our product quality we recommend to remove the filament from your printer
