The days of 3D printing solely with plastics are far behind us. Not only can 3D printing be done using silver, titanium, steel, and waxes—we can also print using ceramic powders for binder jetting and stereolithography (SLA) processes. Tethon 3D was the first company to develop and commercialize ceramic powders as 3D printing material, and they are now using it to create high quality durable 3D printed ceramics.
The company is built around a business that has a strong background in ceramics. They began at the Kaneko Experimental Studio in Omaha, Nebraska, founded by a ceramic sculptor named Jun Kaneko. Their SLA materials are ceramic glass and ceramic: Vitrolite and Porcelite. These can be used for objects that need the same properties as ceramic; heat shock tolerance, heat insulating, anti-corrosive, chemically resistant, controllable porosity, and other factors. It’s used in automotive, jewelry, manufacturing, aerospace, architecture and healthcare.
Porcelite is an alumina-based ceramic resin. Once it’s printed it becomes a polymer clay composite material and after it’s sintered it becomes porcelain with a temperature stability of 2,500 degrees Fahrenheit. Vitrolite is a silica-based glass ceramic resin that’s sintered at a lower temperature. It’s very dense and very smooth, with a milky white color. The two materials could be used on many SLA and DLP printers, and are compatible with both industrial and desktop use.
