Abstract
A low printing temperature thermoplastic filament composition for fused filament fabrication 3D printing is described. The filament includes polycaprolactone in an amount from 70 to 90 wt %, at least one thermoplastic polymer having a melting temperature between approximately 60° C. and approximately 90° C. in an amount from approximately 10 to 30 wt %, at least one antioxidant, and at least one plasticizing agent. This 3D printing filament can be printed out at temperatures below 100° C. and no heated print bed is needed, which saves energy and minimizes the complexity of 3D printer. Besides the low printing temperature, this 3D printing material is bio-friendly which makes it safe for household use.
