We can provide exact replica of your designed 3D models parts in special polymers by our service Rapid Prototyping.

 Direct Methods:

• SLA : This method provides protos with excellent finish & is suitable for parts having intricate details as well as those having excellent surface finish requirement . The Masters for vacuum casting process are made using this process. These protos are pricier than those made with SLS. Also are slightly brittle than SLS protos

• SLS : This method provides protos with slightly coarse finish but with better strength than those done with SLA. Though the as obtained protos have coarse finish, they can be post processed with sanding/lacquering  & finally spray painting to get desired colours & finish

• Short Batch Production by Vacuum Casting : A master made by SLA is utilized to get a rubber mould by vacuum casting & the cast protos are obtained by using special PU based polymers

SLS Rapid Prototyping Service is an additive manufacturing (AM) technique that uses a laser as the power source to sinterpowdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to direct metal laser sintering (DMLS); the two are instantiations of the same concept but differ in technical details. Selective laser melting (SLM) uses a comparable concept, but in SLM the material is fully melted rather than sintered,^[1] allowing different properties (crystal structure, porosity, and so on). SLS (as well as the other mentioned AM techniques) is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves.
