Three dimensional printing head for melting and depositing layers of wire-shaped materials, has various types of wire feeders and feed channels for wires, where soft wire is made of thermoplastic elastomers

摘要

The three dimensional printing head has various types of wire feeders (A,B) and feed channels for the wires. A soft wire is made of thermoplastic elastomers, while a rigid wire is made of acrylonitrile butadiene styrene, polylactide and high-density polyethylene. The wire is provided with a tension-core and different diameters, where the unused wires are inserted or retracted in the closed feed channel. Independent claims are included for the following: (1) a supply channel with a collection device; and (2) a meltable wire with a tension core.
