Overview

What is PolyJet Printing?

PolyJet is a 3D printing technology that uses inkjet technology to layer liquid photopolymer, which is then cured with UV light to create highly detailed and complex parts. It offers a range of materials and can print multi-material objects in a single build, making it ideal for producing realistic prototypes and intricate designs.

How PolyJet Printing Works

1. Design: A 3D model is created using CAD software.

2. Preparation: The model is prepared in slicing software to determine the layer-by-layer path for printing.

3. Printing: The printer jets liquid photopolymer droplets onto the build tray, layer by layer. UV lights immediately cure the material as each layer is deposited.

4. Post-Processing: The printed part may require support material removal and surface finishing, depending on the application.
