As part of their collaboration, 3D resin printing material producer Tethon3D and global chemical company Showa Denko K.K. develop a UV resin for ceramic additive manufacturing.


Showa Denko brings around this table decades of experience in the inorganics, ceramics, and chemical sectors while Tethon has a proven experience in filled UV resins.  


Trent Allen, CEO of Tethon 3D explains that “some ceramic additive solutions have issues with shrinkage which limits feature sizes and often creates unwanted warpage. This material and partnership set a new standard around material properties and reflects the original intent of the ceramic additive manufacturing industry.”


 This high purity alumina material is the first that results from their collaboration. It is loaded 25% higher than other leading industry competitors.  For those who may not know, high-purity Alumina (HPA) is a form of aluminum oxide (Al2O3) with purity levels above 99.99% or 4N+. Alumina is a ceramic material with exceptional hardness, chemical resistance and thermal stability. In this specific development, the ceramic loading is over 75% by volume and 90% by weight. Due to the higher loading, shrinkage in the x, y & z is less than 10 percent after sintering.


“We are expecting to see a lot of growth in Ceramic Additive over the next decade and our Showa Denko America team has been looking to enter the additive market.” Says Masao Horayama, President of Showa Denko America. “We are very excited to launch this first alumina material designed for additive and believe working with an experienced materials team like Tethon is an appropriate venue for bringing Showa Denko’s material expertise to market.”
