SLS nylon powder printing
Nylon sintering is the selective laser sintering processing project is to use spread powder stick to tile a layer of powder materials (such as 3D printing metal powders) in has formed on the surface of the parts, and heated to well below the powder sintering point instead of a certain temperature, the control system to control the laser beam according to the layer of cross section contour scanning on powder, make the temperature of the powder, rose to melting point and sintering, and established under the partial implementation of the bond.When the sintering of one cross section is completed, the thickness of one layer is decreased, and the laying roller lays a layer of uniform and dense powder on it to sintering a new cross section until the whole model is completed.
Material: nylon, nylon and fiber, etc
SLM metal 3D printing
Metal sintering is selective laser sintering process, the process is to use spread powder stick to tile a layer of metal powder materials in molded parts on the surface, heating and to well below the metal powder sintering point of a certain temperature, the control system to control the laser beam according to the layer of metal section contour scanning on powder, make the temperature of the metal powder, rose to melting point and sintering, and established under the partial implementation of the bond.When the sintering of one section is completed, the thickness of one layer is lowered on the workbench, and the laying roller lays a layer of uniform and dense metal powder on it to sintering a new section until the whole model is completed.
Materials: aluminum alloy, stainless steel die steel, titanium alloy, etc
SLA laser photocuring process flow
Fill a resin tank with liquid photosensitive resin, which solidifies quickly under ultraviolet laser beam.At the beginning of the forming process, the lifting table is at the height of a section layer thickness below the liquid surface. After focusing the laser beam, under the control of the computer, scan along the liquid surface according to the requirements of the section contour, so as to cure the resin in the scanned area and obtain the resin sheet of the section contour.The table is then lowered by a thin layer so that the cured resin sheet is covered with a new liquid resin for a second laser scanning cure. The newly cured layer is then bonded to the previous one, and so on until the entire product is formed.Finally, the lifting platform rises the liquid resin surface, takes out the workpiece, carries on the cleaning, the removal support, the secondary curing and the surface smooth treatment and so on.
