Tethon 3D launches High Alumina Tethonite Powder

July 16, 2018

Tethon 3D, Nebraska-based manufacturer of ceramic powders, binders, and other 3D printing services and supplies, announces the launch of High Alumina Tethonite, a high alumina ceramic powder for use in binder jetting additive manufacturing.

“Ceramic powder material development continues to be an area of focus for us,” said CEO Karen Linder. “We have over a decade of R&D experience and expertise with ceramic powders in binder jetting additive manufacturing applications.”

Objects fabricated with high alumina materials are reported more resistant to corrosion, wear and thermal stresses. The high alumina Tethonite powder is composed over 96 percent alumina and can be used by by large enterprise companies for unique technical applications, including oil and gas processing, high voltage bushings, specialty crucibles, laser shields and more.

Tethon 3D companion binder is required for the binder jetting 3D printing process. Partial sintering at 1300C (2372F) can form a porous high alumina object. With heat tolerance up to 2000C (3632F), Tethonite high alumina powder can be used to make parts with densities near 99 percent.

Following the 3D printing process, the printed objects must be sintered in a kiln to achieve vitrification. No other post processing or infusion steps are required. When appropriately sintered, the 3D printed objects are one hundred percent ceramic and exhibit expected physical properties of each of the respective ceramic materials.

Tethon 3D has been at the forefront of ceramic 3D printing, having developed its own Tethonite Ceramic Powder for Zcorp/3D Systems 3D printers, as well as the Tethon3D Ceramic Liquid Binder. Tethon 3D initially released the Tethonite stoneware powder and its companion binder when it began commercial operations in 2014. Since then, the Tethon 3D team has added porcelain, earthenware and now high alumina ceramic powder materials. Tethon 3D also manufactures and sells several ceramic and polymer UV curable resins for SLA and DLP additive manufacturing.

Tethonite is currently offered in four formulations at the same price ($360): earthenware (terra cotta), stoneware, high alumina and porcelain.

DELIVERING SUCCESS AT SCALE

My partner and I approached David at Re3dtech with our project and were greeted with kind and caring service. Throughout the last couple of months we have placed several orders in varying size and were even able to sit down with David and the owner to discuss our needs as a small business. Through this sit down we saw their passion for assisting both small and large clients in achieving their goals. We even had a hiccup with a batch of prints that was immediately addressed and remedied with precision and care. I almost don't want to recommend these guys because I feel like I have stumbled upon a hidden gem in 3D printing services and selfishly want to keep it to myself. Jokes aside we will be continuing our business relationship with the folks there and look forward to growing our order quantities and business with their help.

Re3DTech was instrumental in helping us get our product, Stroba™, to market faster! We needed a technology that could do snap fits and looks and feels as close the injection molded part as possible, and Re3D Tech was there for us. We used SOLIDWORKS Make to get in touch originally, upload models directly, and sign an NDA directly with their excellent team. It was really simple and easy to use their quoting tool as well. Excellent prices, excellent lead times, and superior quality are perfect words to describe our experience with Re3DTech. We went through many prototypes for Stroba™, and we at Goodfriend Innovations™ use Re3DTech for our other rapid prototyping jobs to help get our additional productions out to market faster than the competition. 5 Stars

I provided RE3DTECH three laser scanned ".stl" files for 3-D printing of prototypes. I used their on-line quote and file delivery process. The file acceptance and resultant quote were returned quickly. The parts were received at the quoted time. The parts are quite complex with many holes, angles, curvatures and notches. Each of the parts came out identical to the scanned parts dimensionally and passed the form/fit/function test in the upper level assembly. RE3DTECH has a high quality business process and produces high quality products. I will use them for future prototyping projects and recommend RE3DTECH.

Re3dtech is one of the most honest and reputable companies we have done business with. We decided to look into options for getting parts made in the USA for the retail market. It was awesome to find a local company with humble staff looking to provide their services meeting our criteria, not to mention meeting the Re3tech crew face to face and checking out their operation. Peter was very honest, knowledgable about design. Peter's creative element made working with him a great pleasure. Jim's flexibility was a breath of fresh air and greatly appreciated. CentralSound is proud to scratch the surface with Made in the USA parts in the retail market now, thanks to Re3dtech. Hope to do more business with them in the future.

Re3dtech has consistently delivered the best service I have ever received in the industry. Their response time is unmatched and they always stand by their parts and quality. They regularly make me look like an all star at my job.

It is always a pleasure to have a vendor that provides quality, experience, and always shows as much care for your order, and your product as you do!
