SELECTIVE LASER SINTERING

Powder Sintering is a fast prototyping technology which applies the additive manufacturing or 3D printing method. To do this, a 3D digital file, obtained with the help of CAO (SolidWorks, Catia, Rhinocéros, …) software, is necessary. The prototype is created on a platform of polyamide powder in the centre of the manufacturing trough. A roller (or an arm) will place a thin layer of powder on the bottom of the tray. Just like with stereolithography, a laser will polymerise the powder to harden it. Then the roller will apply another layer of powder, so that the laser can design the following layer, and so on until the full prototype is achieved

 

ADVANTAGES WITH POWDER SINTERING

Powder sintering allows the development of complex shapes
The mechanical resistance of this technology allows validation of clips
The thermal resistance of the pieces is increased

 

DISADVANTAGES WITH POWDER SINTERING

The surface condition is slightly granular / porous
One should expect risks of deformation with this technology
painting finish with your pieces is possible, but it is more difficult and more expensive than it is with stereolithography

Our strong points

Our responsiveness

Painting finish, Metallisation preparation and internal Metallisation

Epoxy impregnation and polishing

We perform and validate the assembly of your subassemblies

Applications

Ideal for the performance of mechanical, thermal and dimensional tests

Functional model

Technical validation

Can allow the creation of tools, because this technology is accurate and high quality

Offered Material

PA 650: Type PA 12 polyamide, white. Combines resistance, durability and chemical resistance and produces prototype pieces which are robust and durable

PA 615 : Glass-filled polyamide. The addition of glass fibre to nylons significantly improves stress resistance, solidity, thermal distortion temperatures, abrasion resistance and dimensional stability.

PP (Polypropylene): This material has excellent plasticity, superior elongation, low moisture absorption and increased durability. It works perfectly for hinges and clips. It is resistant to most acids and bases and has a slight translucent appearance.
