PolyMax™ PLA is an incredibly easy-to-print filament with improved mechanical properties, making it an excellent alternative to ABS. What makes PolyMax™ PLA so different from other PLA? PolyMax™ PLA features our nano-reinforcement technology which significantly increases its ductility. Ductility is the ability of a material to exhibit plastic deformation before fracture.In simple words, PolyMax™ PLA will always bend instead of breaking. The opposite of ductile materials can be seen as brittle materials. Printing and Drying Settings? Printing Temperature: 190˚C - 230˚CBed Temperature: 25˚C - 60˚CPrinting Speed: 40mm/s - 60mm/sFan: ONDirect Drive:Retraction Distance: 1mmRetraction Speed: 20mm/sIndirect Drive:Retraction Distance: 3mmRetraction Speed: 40mm/sDrying Settings: 55˚C for 6h(Only if the material has absorbed moisture) What is PolyMax™ PLA heat resistance temperature? PolyMax™ PLA is a PLA based product and will display similar heat resistance temperature as regular PLA: ~60˚C (Glass Transition Temperature) For similar printability with higher heat resistance we can recommend PolyMax™ PETG (~80˚C) Spool Dimensions? 0.5kg cardboard spool:Spool Inner Hole Diameter: 55±1mmSpool Diameter: 200±1mmSpool Width: 65.6±2mmSpool Weight: 190±7g 0.75kg cardboard spool:Spool Inner Hole Diameter: 55±1mmSpool Diameter: 200±1mmSpool Width: 50.6±2mmSpool Weight: 125±7g 1kg cardboard spool:Spool Inner Hole Diameter: 55±1mmSpool Diameter: 200±1mmSpool Width: 65.6±2mmSpool Weight: 140±7g 2kg cardboard spool:Spool Inner Hole Diameter: 55±1mmSpool Diameter: 250±1mmSpool Width: 117.2±2mmSpool Weight: 370±18.5g 3kg cardboard spool:Spool Inner Hole Diameter: 55±1mmSpool Diameter: 250±1mmSpool Width: 117.2±2mmSpool Weight: 425±21.3g 5kg plastic spool: 32mm/300mm/160mm/819gSpool Inner Hole Diameter: 32±1mmSpool Diameter: 300±1mmSpool Width: 160±1mmSpool Weight: 819±30gSpool Material: PP
