Inkjet 3d printer

Types of Inkjet 3D Printer

Inkjet 3D printers are also known as material jetting 3D printers. They use a print head that jets photopolymer liquid resin onto a model. MJ technology cures the resin layer-by-layer with ultraviolet light. Inkjet 3D printer types include:

PolyJet Printer

This printer jets liquid photopolymer onto a build tray. The material solidifies as UV light hits it. PolyJetting produces smooth multi-color and multi-material parts.

MultiJet Printer

MultiJet printing is close to PolyJetting but uses different materials. This printer jets the photopolymer material in layers like ink droplets. It builds the part layer by layer. It cannot produce smooth parts but is superior when building functional test prototypes.

3D Inkjet Printer

This printer prints parts using inkjet technology but applies it in the 3D realm. This involves using inkjet technologies deposited on layers that harden resin. The inkjet printer applies hardening ink just like in simple 2D printing. The 3D model increments develop where the ink hardens and creates a solid layer. The process is repeated until the part is created.

Commercial Uses of Inkjet 3D Printer
