What is 3D Printing?


3D Printing is an ideal process used in Rapid Prototyping parts for engineering tests and next generation products, as well as art pieces and architectural models.  There are several different 3D Printing processes and a variety of materials to choose from. There are 3 kinds of printing techniques which are SLA/SLS/FDM.

SLASLA(Stereo lithography) stereo lithography technology, also known as the process is mechanical, laser, photochemical, software, crystallization control technology.

Tuowei Model has 2 sets of Printing Machines. One is Objet30 imported from Israel,another is made in China. The biggest printing size is 600mm*600mm*400mm.


Surface finish:painting/laser etching/silk-screen and so on.

For small complicated parts, SLA will be the first choice.It could machine the whole part with 1 piece and have tight tolerance.

SLS:Selective laser sintering is using laser selective sintering of layered solid powder, and the curing layer overlap to form a desired shape of the sintered parts.

Material: Nylon/Nylon12/Nylon+GF

Surface finish: not adhesive with oil(painting) & glue,cleaning the surface

The materials need to withstand high temperature up to 100°or so.
