Now many industrial designers make hand models are 3D printing molding production, because the printing production cycle is fast, low cost, high precision, but do you understand the 3D printing molding method? You know the following three kinds of 3D printing to make you more comfortable.

The first is the FDM molding method, which is suitable for schools and simple verification teaching for students. This kind of printer is light and small, cheap, is a kind of we often see, see the following figure, the forming principle is like making a cake according to the shape of your product, like toothpaste, followed by the outline of the product. This printing cost is the cheapest, the printed product precision is not high, the surface is very rough, the material toughness is good.

The second is SLA laser molding, this printing molding method is currently the most suitable for 3D printing hand model, this forming principle is the laser curing principle, the use of UV laser irradiation material curing laminated accumulation molding. This printing cost is slightly higher than FDM printing, because of high precision, smooth surface, material close to ABS, but note that the name of this material is photosensitive resin, there are domestic materials and imported materials, imported materials are not so brittle can lock screws, the buckle is not easy to break,

The third is SLS powder sintering molding. This printing is suitable for engineers with high material toughness requirements, because the printed material is similar to nylon. This forming principle is similar to SLA forming principle. Only the material of SLA is a photosensitive resin liquid material, and the material of SLS is a powder material. The disadvantage of this material is that the surface of the printed product is very rough, as rough as the FDM desktop and will not be smooth when polished. But this printing cost is up to 10 times higher than the SLA cost.
