Metal 3D Printing
Method

Unlike other powder bed fusion methods, metal 3d printing technology user a laser to scan and selectively melt the metal powder particles bonding them together by the same token building parts layer-by-layer.

Also, materials used in this method are metals that comes in a granular form. Direct metal laser sintering (DMLS), the aforementioned powder is composed of materials which have variable melting points that melt on a molecular level at raised temperatures. Set by the equipment manufacturers, layer height set in metal 3d printing, ranges between 20 to 50 microns and differs based on the metal power properties. Build part size of metal 3d printing machinery is 10 x 6 x 6 inches or (250 x 150 x 150 mm). However, larger machines which are available, build size range up to 20 x 11 x 14 inches or (500 x 280 x 360 mm). DMLS metal 3d printing systems correlate more like batch production capabilities of SLA or FDM machines. Components are often oriented in an angle to minimize the probability of warping and maximize part strength in critical directions.

Post finishing possibility can be done as a request with various post finishing techniques used to improve the accuracy, appearance, and mechanical properties of metal 3d printed parts. Also, CNC machining may be selected for dimensionally critical features for parts with holes or threads.
