3DP that is 3Dprinting, the choice 3d molding of 3DP technicality 3D printer using the standard inkjet printer printing technicality, according to the liquid connection body laid on the powdered laminate to print out the cross-sectional data method to establish each component step by step, the establishment of three-dimensional digital model, the choice of this technicality to print out the forming of the physical model of the trial product with specific goods with the same color, but also be able to Colorful profiling conclusions immediately outlined in the model, the entity model trial products transmitted by the information content is relatively large.
EmanualSachs expert professor of the mobile mine Massachusetts Institute of Technology in the United States in 1989 applied for the patent rights of three-dimensional printing process (3DP). This is also a kind of porcelain, metal materials, such as powder as raw materials, according to the adhesive will be each layer of powder bonded together, according to the layer by layer stacking and forming. 1993, the powder bonded into shape processing process is to complete the wonderful printing out the best is the processing process, the application of cooked plaster powder, porcelain powder, metal powder, etc. as raw materials, is the current more perfect color 3D printing technology sex.
SLSps selective laser calcination mtr hk technology, that is, SelectiveLaserSintering, and 3DP technology is similar, the same choice of powder as raw materials. The difference is that this type of powder can dissolve under the continuous high temperature of the laser beam. The powder coating equipment first lays down a layer of powdered raw material, heats the material to a point close to the melting point, and then, using a laser beam, scans the profile of the solid model that must be formed so that the powdered material melts and is partially bonded together by calcination. Under this type of full-process continuous cycle system, the powder is deposited layer by layer until it is finally formed.
SLS was first clearly proposed by Carlckard of the University of Texas at Austin in 1989 in his master's thesis. Over the decades, the University of Texas at Austin and DTM have made significant achievements in the development of machinery and equipment and in the development and design of processes and raw materials in the SLS industry. The French company EOS has also carried out a lot of research in this sector and has developed a series of forming machines and equipment. Among them, the laser calcination technology is the 3D printing technology with more complicated forming fundamentals, the largest forming standard, and the largest cost of equipment and raw materials, and it is also the technology that is more harmful to the development trend of 3D printing technology in the long run at this stage. At this stage, there are many types of SLS technical forming raw materials, which can be nylon, wax, porcelain, metal materials, etc.
