AI Technical Summary
Existing FDM consumables cannot meet the multiple performance requirements of high rigidity, high toughness, wear resistance, fatigue resistance, and flame retardancy. In addition, high filler doping makes extrusion difficult, traditional equipment is costly and complex to operate, and it is difficult to achieve multi-functional material stacking.
The printing consumable adopts a multi-functional composite structure, including a difficult-to-extrude core layer and an easy-to-print outer layer. It is co-extruded through a multi-channel die head. The melt index of the easy-to-print outer layer is higher than that of the difficult-to-extrude core layer. It is designed as a multi-layer or multi-core coaxial structure to ensure smooth filament feeding and endow the printed parts with flame-retardant, conductive and other functions.
It enables multi-functional material stacking, improves the mechanical properties and functionality of printed parts, reduces equipment modification costs, ensures filament feeding stability and surface finish, and is suitable for conventional FDM equipment.
