Tethon 3D announces composite resin 3D printing patent



3D tethon announced the issuance and publication of its latest patent which enables 3D printing of composite resins.

The “Photopolymer Development Resin Base for Use with Three-Dimensional Printer” patent (U.S. Patent Number 11,126,088) covers a range of products manufactured by Tethon 3D under the trade name “Genesis,” a group of light-curing polymer resins for use in the large-scale formulation and production of SLA and DLP 3D printing materials.

Pure Genesis is said to be unsuitable for 3D printing until the addition of a powdered solid material that allows the material to be printed as a polymer composite. According to the patent, the photopolymer developing resin base functions as a binder precursor material with the ability to accept solid powder or liquids for UV printing. Thanks to the patent, Tethon 3D states that “countless types of materials and composite powders are potentially printable”.

Since its introduction in 2016, Genesis has facilitated the R&D and production of custom 3D printing resins in hundreds of facilities. Formulations incorporating alumina, zirconia, silica, silicon carbide and hydroxyapatite in Genesis would be desirable in the aerospace, automotive, metal foundry, jewelry, dental, electronics and biomedical.

“Genesis is a line of multiple resins. By formulating an evolving range of resin bases that achieve specific goals, such as high load and physical flexibility, it allows a wider range of solid materials to be added to the potentially endless means of developing specialized materials that perform specific applications. Commented Tethon 3D CTO Greg Pugh.

“We have found that companies in the semiconductor industry want to use the same powder that they use in traditional manufacturing methods while embracing additive manufacturing,” added Trent Allen, CEO of Tethon 3D. “Dental labs want to use the same zirconia powders that are used in milling and defense companies want to use the same ceramics, carbides and metals that they have successfully sent into space since the 1960s. Genesis resins are trusted by hundreds of customers and over a dozen in the Fortune 500 to make UV material manufacturing more accessible.
