There is no substitute for an accurate prototype, as it communicates features & quality that are impossible to validate or show via 2D drawings or CAD models. We offer on-demand rapid prototyping services and assist clients in their engineering-design needs. Our rapid prototyping services bring CAD files and design ideas to life in form of real physical models. What so ever are your needs, we can assist you to define and pursue a course of action.
The prototypes are ideal for concept modelling, verification, production mock-up and functional testing. Innumerable design variations, with functional plastic models, can be created to develop the most befitting product.

Stereolithography – more commonly referred to as SLA 3D printing – is one of the most popular and widespread techniques in the world of additive manufacturing. It works by using a high-powered laser to harden liquid resin that is contained in a reservoir to create the desired 3D shape. In a nutshell, this process converts photosensitive liquid into 3D solid plastics in a layer-by-layer fashion using a low-power laser and photopolymerization.
SLA is one of three primary technologies adopted in 3D printing, together with fused deposition modeling (FDM) and selective laser sintering (SLS). It belongs to the resin 3D printing category. A similar technique that is usually grouped with SLA is called digital light processing (DLP). It represents a sort of evolution of the SLA process, using a projector screen instead of a laser.
Selective laser sintering
Technology that uses a laser to sinter powdered plastic material into a solid structure based on a 3D model. SLS 3D printing has been a popular choice for engineers in product development for decades. Low cost per part, high productivity, and established materials make the technology ideal for a range of applications from rapid prototyping to small batch or bridge manufacturing
Recent advances in machinery, materials, and software have made SLS printing accessible to a wider range of businesses, enabling more and more companies to use tools previously limited to a few high-tech industries.
In this extensive guide, we’ll cover the selective laser sintering process, the different systems and materials available on the market, and when to consider using selective laser sintering over other additive and traditional manufacturing methods
The process starts by placing a two piece silicon mold in a vacuum chamber. The raw material is mixed with degassed and then poured into the mold. The vacuum is then released and the mold removed from the chamber. Finally, the casting is cured in an oven and the mold removed to release the completed casting. The silicone mold can be reused.
In some machines the chamber where the material is mixed a pressure can be applied to increase the pressure differential between the mold cavity and the mixing chamber.
