With the development of laser rapid prototyping technology, people in increasing the precision of laser rapid prototyping products, enlarge the using range of molding material, explore new methods of forming process.
Out at the moment, forming layered manufacturing technology mentioned above, also developed a material removal and increase the molding technology.
data remove forming and increase the forming technology integration, its principle is: the laser melting data accumulation in forming local, after milling parts.
prototype data performance to meet:
to rapidly and accurately processing prototype;
built function of data directly with the RP system performance is close to parts zui eventually use of strength, stiffness and wave resistance, thermal stability and so on request; For the subsequent disposal of rapid manufacture of moulds, the 3 d Systems company early prototype using polyacrylic acid as materials, poor performance, then replace polyacrylic acid with epoxy resin, mild parts progress greatly. Currently have developed plastic belt, stainless steel and ceramics, can be applied to the specification of LOM process of laser rapid prototyping.
in SLS laser rapid prototyping technology, the original only choose such as resin, polycarbonate, nylon and other materials. After gradually to hardening plastic, thermosetting plastics, thermoplastics, etc. Ceramic powder is added in the photosensitive resin granule can manufacture special function keys. Then carry out to the metal powder ( Or ceramic powder) The selected laser sintering moulding directly, this material has the advantages of high strength and thermal stability. Molding technology in recent years the rapid develop, material varieties are also carried out from time to time.
the industrial application of laser rapid molding machine is mainly used in a variety of different photosensitive resin or easy sintering plastic manufacturing plastic mold. Use a metal or ceramic powder powder directly manufacture metal mould is still in development stage.
forming process and the development of new materials are also carried out from time to time, American airlines have developed a laser molding materials of titanium components. The data of molding process similar to SLS process. The difference is that he is able to make high density parts, without hot isostatic pressing. Using pure titanium and Ti - 6AL- 4 v and Ti 6Al- 2 sn made of titanium forming parts have good mechanical properties. Dickten company is developing a new and different forming materials, using the parts of it do not demand roasting. Like Japan GMET company after ceramic powder are added into the photosensitive tree powder. Can manufacture special functions or rapid molding directly. Therefore, in the near future there will be more new technology and molding materials.
