Laboratory inject 3D printer for powder materials

The paper presents the results of development and testing of a laboratory 3D inkjet printer with an open architecture. The ability of designed 3D printer to forming structures with defined architectonics from different powder substances with an average particle size of 50-150 μm were shown. Installed drop-on-demand system allows dispensing dropwise liquids with a pH of 2 to 9 and a viscosity of 1 to 1000 mPa·s as a binder components. The printing resolution of the developed system is 100 microns, which is comparable to the resolution of commercially available powder 3D inkjet printers.
