Plastic Prototypes

A complete rapid prototyping service through selective laser sintering of thermoplastic materials.

Plastic prototyping:
the sintering process

The output of selective laser sintering

Selective Laser Sintering is a technique for rapid prototyping that uses thermoplastic materials to create prototypes and parts with complex geometries for use in the automotive and industrial sectors.

The most commonly used thermoplastic polymers are Polyamide (PA) and thermoplastic rubbers (TPE, TPU), exploited in the form of powders also with 30 percent fillers (glass filler, aluminum filler, carbon filler) that incentivize the performance of the plastic prototype from the thermal point of view.

Through laser sintering, the polymer-based or composite powders are solidified into objects with no real dimensional limits. Large objects can in fact be broken down into smaller sub-parts that already have mechanical joints to be reassembled.

SLS 3D Printing

Technological advances and a wide variety of source materials lead to the evaluation of the SLS printing for the production of advanced components.

The Flight HT403P-H 3D printing system offers a rapid prototyping service that meets the demand of different customers and industries.

The polymer used is specific for industrial applications and colored black so as not to soil the surface during environmental testing. The high quality of the molded parts also allows them to be painted directly, without the need for manual retouching, and prepare them already for the next stage of the development process.

The advantages of our SLS printing

  • An “open” printing system, which allows the use of a very large number of parameters
  • 500W “fiber” laser, which supplants 130W CO2 laser sources and avoids power fluctuations
  • extreme printing speed
  • printing chamber 400x400x540 mm (h)
  • smooth and precise details
