Definition: 3D printing simply means that the 3D model in the computer is printed out in layers by 3D printing equipment, and the layers are superimposed into a physical product.
Process: Have a physical object-3D scanning-3D printing-post-processing (polishing, coloring, plating, silk-screening, etc.)
Have picture or design draft-3D modeling-3D printing-post-processing (polishing, coloring, plating, silkscreening, etc.)
The most difficult point here is the 3D modeling, most of our designers have a certain understanding of graphic design, but not much understanding of 3D modeling, which is also a shackle limiting the development of 3D printing, complex design 3D modeling is not too cheap.
3D printing materials: 3D printing materials up to more than 50 kinds of materials, corresponding to the different needs of everyone, commonly used materials are as follows.
PLA material: polylactic acid biodegradable environmental protection material, the cheapest material, color optional, general accuracy, the surface has layer pattern, suitable for the budget is not high, the model accuracy is not high, the strength of a slightly demanding group. Currently on the market there is a direct sale of finished 3D printed PLA vase, the aesthetics are not bad.
Resin material: polymer resin, resin can also be subdivided into white ordinary resin, yellow toughness resin, high temperature resin, transparent resin, is the most used material in 3D printing material, the later can be finely polished, coloring, plating, screen printing can be done; suitable for display model, hand model, hand board proofing, crafts, jewelry, etc., white ordinary resin is inexpensive; the disadvantage is that the resin strength is poor. Not very strong, can not fall.
Nylon material: nylon has white nylon, HP black nylon, high strength, toughness, suitable for industrial parts, is a particularly suitable material for researchers and developers. In addition, white nylon in foreign clothing design, jewelry design applications are also quite extensive
Metal materials: metal gold, silver and copper, do jewelry with, there are stainless steel aluminum alloy to do performance testing with is also very wide.
Today first say these, in fact, the traditional process is to mold to do the product, 3D printing is a direct 3D model to print out the finished product, and do not need to do the mold, so you have any ideas welcome and I communicate
