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 500 PolyJet Matrix
TM 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 lamps
during printing step.
Each horizontal layer is built one by one to produce
a full 3D part.

The Connex500TM is able to jet two distinct model materials in many preset
combinations.
Resolutions : 600 x 600 x 1600 dpi
Layer Thickness: 16 to 30 µm
