Material Jetting (MJ)

Material jetting is one of the fastest and most precise 3D printing technologies. The parts here are created by applying photopolymer drops hardened with an UV lamp. The printer jets resin from a number of printing heads at once, then the resin solidifies, and the whole process repeats itself layer-by-layer until the product is complete.

Stratasys Objet J750

The printer can use up to 6 materials per printing session. They are either used separately, or mixed together, enabling the creation of a new material with specific properties. Objet J750 can also process coloured materials – it is able to create up to 360 000 colours. Due to the special “Voxel printing” feature, enabling the access to the computer model, allows setting up mechanical or optical properties of individual points (voxels).

Stratasys Objet 500 Connex1

One of the most precise printers today, which enables the manufacture of high-quality parts using different types of photopolymers. The printer can print from two materials in one printing process, or mix the materials together. The resulting models are solid, dimensionally stable, allowing easy surface treatment after the printing process.
