The studies carried out by CRP Technology from 1996 have changed the scenario of Rapid Prototyping introducing a new concept of Rapid Manufacturing: WINDFORM® materials have allowed the technology of selective laser sintering (SLS) in order to realize high performing parts for wind tunnel applications as well as finished and functional parts. All WINDFORM® materials can be CNC machined.
The development of the Windform® line is due to the need to introduce in the market more performing RP with properties able to distinguish them as the main SLS materials.
All WINDFORM® materials can be CNC machined and processed with tooling machines if necessary, for example to obtain plans and seats with narrow tolerances.
The development of the Windform® line is due to the need to introduce in the market of RP more suitable materials compared to those available, with particular structural properties. For this reason Windform® powders are different and can be considered as the main SLS materials in high-performing applications.
The line of WINDFORM® polyamide materials is composed of different kind of powders, patent-pending and with trademark, developed by the R&D department of CRP and sold worldwide. On the other hand Windform® PS is a polystyrene material that is used to realize disposable patterns for casting.

Windform® PS - Polystyrene-based material suited to produce complex investment casting patterns
Better surface quality and detail reproduction
Less “curling” effect in the first layers
Very low ash content, therefore perfect suitable for highly reactive alloys, such as Titanium alloys too, besides aluminium, magnesium, steel and nichel based alloys.
