Ceramic Powder 3 D Printing

Printing debinding and sintering.

Ceramic powder 3 d printing.

Successful 3d printing of ceramics using stereolithography is achieved through the photopolymerisation of preceramic polymers to yield silicon based ceramics of a class known more widely as polymer derived ceramics including silicon carbide and silicon oxycarbide. The slurry content can be 3d printed by either photopolymerisation inkjet printing or extrusion. On the basis of form the 3d printing ceramic market analysis is done into filament liquid and powder. Tethon 3d has just released their newest ceramic powder for the creation of high alumina prints.

Extrusion a paste or slurry of clay is pushed through a nozzle and parts are built up layer by layer like on a desktop 3d printer. Slurry based ceramic 3d printing technologies generally involve liquid or semi liquid systems dispersed with fine ceramic particles as feedstock either in the form of inks or pastes depending on the solid loading and viscosity of the system. The powder segment holds the significant market share due to increase in demand for laser sintering technology in commercial applications. However 3d printing is only part of a longer manufacturing process.

Nanoe s zetamix product line makes our powders and their properties available to most 3d fdm printers. Ceramics have been a hot trend in 3d printing materials for a while now. There are five major processes for 3d printing ceramic. Tethonite is an ideal powder for binder jetting systems available in a variety of formulations for quite some time now adding the high alumina version to their portfolio.

As with most tethonite powders it works alongside tethon s ceramic binder. Inspired by ceramic powder injection processes the zetamix manufacturing process consists of three stages. Today ceramic 3d printers are mostly expensive industrial additive manufacturing systems. Extrusion binder jetting photopolymerization and powder sintering.

Resolution is lowest on this technology but it also scales up to the largest build volumes. These systems vary in the 3d printing technologies they use to 3d print ceramic material. Producing complex parts with ceramics is challenging and costly with 3d printing. Binder jet 3d printing known variously as powder bed and inkjet and drop on powder printing is a rapid prototyping and additive manufacturing technology for making objects described by digital data such as a cad file.
