Direct Digital Manufacturing and Additive Manufacturing
Windtunnel scale model of a F1 carAmong the first in Europe CRP Technology is involved since 1996 in Direct Digital Manufacturing (DDM) namely Additive Manufacturing with SLS technology and Windform® composite materials CRP patent-pending and branded.
Direct Digital Manufacturing and Additive Manufacturing refer to Rapid Manufacturing and namely to the production of finished and functional parts through additive techniques of manufacturing (Layer Manufacturing).

With Direct Digital Manufacturing and Additive Manufacturing CRP Technology supports the customers offering:
  • Finished and functional parts for sporting vehicles, road vehicles and concept models
  • Mock-up for assembling, fitting, functionality and performance tests (for example on static and dynamic dyno and on track)
  • Finished and functional parts for limited productions
  • Mock-up for windtunnel
  • Functional prototypes
  • In-scale reproduction for physic archive
Moreover CRP Technology sells SLS composite material Windform® and the R&D department always studies new innovative materials and processes.

The main properties of Direct Digital Manufacturing and Additive Manufacturing are:
  • Total freeform and no limits in designing (Design For Functionality instead of Design for Manufacturing)
  • Production of pieces with undercuts and complex features that might be difficult to realize with traditional production systems
  • Reduction in product and project realization timing and reduction in cost production
CRP Technology has been in the field of Additive Manufacturing and Rapid Prototyping since 1996 when it began to develop the SLS technology as well as new polymeric with high structural properties (the family of Windform® materials). The department of Rapid Prototyping and Additive Manufacturing of CRP Technology creates a finished model in short time and it is suitable for functional tests, fluid-aerodynamic, fitting and assembling.
For example it is possible to produce a windtunnel F1 1:1 mock-up equipped with helmet and rear-view mirrors.
Focus: Selective Laser Sintering (SLS)
Sinterizzazione Selettiva a mezzo Laser
The selective laser sintering can produce a prototype by layer overlapping of polymeric material.

In an inert atmosphere room and with a constant temperature a roller rotating at opposite direction towards its forwarding, lays a thin layer of powder on a platform where the addressed laser ray sinters the material providing the Δ necessary to melting the powders.
The system does not need supports because the parts stand thanks to non-sintered powders.
