Polyjet is ideal when the requirement is for a prototype with multiple colors or materials, closely emulating the look, feel, and function of final products. It can be in a single build process, print parts, and assemblies made of several materials with different mechanical and physical properties. Also for parts that require soft materials or to produce a prototype that requires a soft overmold. Ready to build your project with Polyjet? πŸ‘‰ Start Your Polyjet Project

Polyjet Technology

PolyJet printing works by jetting tiny droplets of liquid photopolymer onto a build platform in precise layers, which are immediately cured with UV light. This process repeats layer by layer, allowing for smooth transitions between materials and colors within a single print, resulting in detailed, high-resolution parts.

Application Anchor

Applications

Rapid Prototyping

Polyjet is ideal for creating detailed, high-resolution prototypes that closely mimic final products in appearance and texture.


Medical Models

Polyjet produces accurate, multi-material anatomical models for surgical planning, education, and device testing.


Consumer Products

Polyjet enables realistic prototypes with different textures and colors, allowing designers to evaluate functionality and aesthetics.

MJF FAQs

What is the largest part that can be made with MJF
The max build size for the machine is 14.96 x 11.18 x 14.96" But as with other processes, it may be possible to split large parts into smaller ones to fit the build volume.
What is the minimum recommended wall thickness for MJF parts?
The minimum recommended wall thickness is 0.02", but thicker walls can achieve better mechanical properties
