4. Fused deposition molding

The basis of this process is the heating and melting of thermoplastic polymer materials into filaments. At the same time, under the control of the computer, the three-dimensional nozzle selectively coats the material on the workbench according to the sectional profile information, and forms a cross section after rapid cooling. The above process is then repeated to continue the meltblown deposition until the entire solid shape is formed. This molding method can be imagined as two tubes of toothpaste simultaneously extruded, one extruded to be a model material, one extruded to be a supporting material, and stacked on a forming surface.

5.MJM multi-nozzle 3D printing technology

The photosensitive resin material is sprayed out through a plurality of print heads, and after the material is ejected, the ultraviolet light in front of or behind the print head solidifies it, which is a relatively fine curing method.


High-resolution digital light processor (DLP) projectors for curing liquid photopolymers are a very advanced way. They use ultraviolet light (white light) on the machine to illuminate a cross-sectional image and liquid The photosensitive resin is cured.
