As a 3D printing technology,Fused Deposition Modeling(FDM)has the advantages of simple structure,convenient operation and low cost.At present,3D printer with FDM technology uses standard printing materials,which has high requirements for printing materials and relatively high price.In the process of 3D printing,particles will be wasted,which will affect the environment.In this regard,a 3D printer based on screw extrusion of particle materials is designed,which directly uses traditional particle materials for extrusion modeling without standard diameter printing materials.This design aims to reduce costs and waste,and achieve more environmentally friendly"green"printing.
