Different types of RP methods
The Poly jet process
Stereo lithography (SLA for stereo lithography apparatus),
Selective laser sintering (SLS),
Fused deposition modeling (FDM),
Laminated object manufacturing (LOM),
Inkjet systems and three dimensional printing (3DP).
Solid Ground Curing
Rapid prototyping is a layer -based fabrication that quickly create physical objects from CAD data
The Poly Jet 3D printer rapid prototype system deposits liquid acrylic photopolymer through nozzles to produce plastic 3D models for concept analysis, functional prototypes, silicone and urethane molding, and end product use.
The Poly jet 3D printer uses acrylic and flexible rubber-like photopolymers that are cured to solids via exposure to ultraviolet light
By using Rapid Prototyping Techniques (RPT) car manufacturer today produce plastic parts for Prototypes faster and even cheaper compared to the techniques used up to now.
As well metal parts made either by RPT combined with metal casting processes or by poly jet, are inserted earlier as usual into dummies and tests.
As a consequence of this process the automotive industry increasingly demands to have sheet metal parts also earlier than now at their disposal.
Sheet metal forming tools are geometrically complex, massive and require a high surface quality. The material must be stiff and resistant to pressure and wear.
