3D Printing China.

3D-Printing is the less costly process of rapid prototyping which turns the 3D CAD data to quickly produce a three dimensional model for conceptual evaluation. Where an ordinary printer lays down a single 2D layer of ink on a sheet of paper, these printers add the extra dimension by printing layer after layer until you have a real, 3d object similar to your CAD model. Manufacturers report enormous productivity gains from using 3D-printed parts.

Stereolithography process produces plastic parts directly from 3D CAD model; by solidifying the surface of a liquid photo polymer layer by layer with the help of a laser beam. When the laser beam hits the liquid, it solidifies the resin. When a layer is fully traced, the elevator is then lowered in the vat. The self-adhesive property of the material causes the layer to stick with each other and in this way a 3D-part is formed in multi-layers.

SLS also known as “Selective Laser Sintering”, primarily used to quickly produce 3-dimensional prototypes, parts, direct mold inserts, tools, and lost wax casting patterns. SLS process provides durable, metal, plastic or rubber like prototypes directly from CAD model. These prototypes can be used as test parts for form, fit and function. SLS technology provides broad range of materials like rigid thermoplastics, stainless steel, polystyrene, thermoplastic elastomers, cast form plastic for investment castings.

Typical tolerances on our SLA models are about +/- 0.005″. For parts over 5″ we can hold around +/- 0.001″ to 0.0015″ per inch. Part geometry and build orientation can also have an effect on tolerances.

High Resolution is a special mode on a Viper si2 SLA system. The diameter of the laser beam is decreased from about 0.010″ to about 0.003″-0.004″ and parts are built at a layer thickness that has been shaved from 0.004″ to 0.002″. The effective area for this mode is 5″x5″. Parts best suited for high resolution are small with intricate detail and/or extremely small features. High Resolution parts are more expensive than their Normal Resolution counterpart.

It really depends upon the functionality of the product you want to achieve. We have various technologies available, to make functional parts e.g. FDM & SLS and CNC machining direct on industrial materials. Please check specifications and applications of different materials. Sometimes we machine prototypes from solid block of metal or plastic block to get the maximum strength when demanded.

We provide full range of Prototyping service, using our in-house facilities and network of partners. Some of services we provide 3D printing, SLA, SLS, FDM, CNC machining, Vacuum Casting, Investment casting, Sheet Metal parts and tooling, CAD/CAM service. Lately we started our new division of Architectural modeling. For more information please check our Service section or send us your request.
