Stereolithography

[English] [français]

HIGH DEFINITION PROTOTYPES RIGHT UP TO XXL SIZE

his process is how 3D printing began. It consists of the layer-by-layer polymerisation of a photosensitive resin using a laser. To see how the process works, take a look at the video in the video tab.

Thanks to our 10 stereolithography machines, we are able to create a particularly accurate prototype or model working from a 3D CAD file. We are specialists in decorative elements (paint finish), precision parts and also very large scale objects with two systems with a capacity of 1500x750x550mm.
We use the very best resins to date, the Xtreme resin (grey) and Xtreme white. We are also able to produce clear pieces (Clearvue).

And we can also produce biocompatible pieces. Indeed the WaterShed XC resin has been given USP Class VI grading.
In June 2014, we announced as a world exclusive our purchase of a new 3D Systems "ProX 950" 3D printer with dimensions of 1500x750x550mm.

"We are delighted to see our new technology adopted so quickly by clients as professional as ERPRO and Sprint Plastique," said Pascal Rizzon, Sales Director EMEA Production & Professional 3D Systems.
"ERPRO and Sprint Plastique are first class service providers who show constant innovation in their offers to industrials, with the very latest developments representing the new generation of 3D printing."

Erpro ; first service provider in Europe to purchase the VIPER PRO (2007)
As a pioneer in rapid prototyping and digital manufacturing services (...) we are delighted Erpro is to be the first service provider in Europe to invest in this system," declared Joël Delanoue, Director of 3D Systems France.

Erpro, first purchaser of the Viper SI2 / 3D Systems in the world (2001)
On our Viper SI2, in HR (High Resolution) mode, we produce pieces of a quality unequalled to date (layers of 0.05 mm, details smaller than 0.1 mm)
- The best resolution possible with stereolithography technology. 
- The best detailed, fine, small pieces.

Advantage

- Precision
- Surface finish
- Very large pieces
- Biocompatible pieces
- Transparent pieces
- Working pieces

Process

The basics of stereolithography lie in photopolymerisation.
A laser works on a photosensitive resin and reconstructs the piece to be made by superimposing successive layers. Supports are required to keep the piece(s) in the resin during manufacture.

Stereolithography
/ The laser beam sweeps the surface of a tray of resin wherever the resin needs to be rendered solid
2/ The platform lowers one level following the Z axis and the liquid resin covers the part already solidified over its entire surface
3/ The laser polymerises the following layer 
The drawing below illustrates the concept
