Stereolithography

Technology based on Photopolymerisation of liquid resin with a UV laser.

Choice of resins:

- Transparency

- Thermal applications (> 250°C)

- Mechanical applications

- Biomedical application (contact)

High resolution for jewelry, connectors,

medical applications,...

Layer thickness:25, 50, 100 to 150 µm

3D Printing polymer technology

Objet Connex 500TM

PolyJet Matrix TM

Technology based on inkjet printing process.Jetting heads print fine resin drops, layer by layer. The resin is photosensible and cured by 2 UV lampsduring printing step. Each horizontal layer is built one by one to producea full 3D part.

The Connex500TM is able to jet two distinct model materials in many presetcombinations.Resolutions : 600 x 600 x 1600 dpiLayer Thickness: 16 to 30 µm
