Evonik and Cubicure to build elements for Very hot Lithography 3D printers


German specialty chemicals enterprise Evonik has entered into a cooperative agreement with Cubicure to make supplies for its Very hot Lithography technologies. A patented approach of 3D printing certification, Cubicure Hot Lithography processes materials with bigger impression toughness, toughness and heat deflection than those typically utilized in typical “cold” SLA procedures. Collectively the associates have been producing custom made formulations for the process to much better meet the needs of industrial manufacturing clients. They be expecting the initially products and solutions of this partnership to be produced out there in the in close proximity to potential, and have announced a preview of their results at November’s Formnext 2019.

“The joint strategic progress task with Evonik is presently in an highly developed condition,” comments Robert Gmeiner, CEO and co-founder of Cubicure, including that this most up-to-date advance “is an crucial setting up block on our way to stable and scalable additive manufacturing procedures.”

What is Scorching Lithography?

Cubicure was started in 2015 as a spin-off of TU Wien (Vienna University of Technology). It is Scorching Lithography method was identified in an endeavor to develop the materials options available to typical SLA 3D printing certification. Specially, the crew developed a method that would aid the use of significant viscosity polymers, thereby maximizing the product homes of the thinner supplies utilized in SLA. As the identify of the process indicates, Cubicure achieves this by raising the operating temperature of its lithography units. Depending on the materials picked, this can be just about anything up to a temperature of 120°C.

A heated plate carries slim layers of materials into the processing region exactly where it is then selectively fixed by a precision laser-scanning-technique. With this set-up, Cubicure makes sure that the temperature of the materials continues to be constant, as a result eliminating the regular issues of functioning with viscous resources.

3D printing certification at Evonik

As a major specialty polymer small business, Evonik is investing intensely in the long term of 3D printing certification. Not long ago, the enterprise has taken actions to optimize its output of VESTOSINT 3D printable PA12 to satisfy desire, and it has been partnering with 3D printing certification technological know-how builders to be the initially to insert its supplies to their platforms. As Thomas Große-Puppendahl, Head of Innovation Growth at Evonik describes, “Our strategic emphasis is on acquiring and production ‘ready-to-use’ superior-efficiency supplies for all appropriate 3D printing certification systems. Shut cooperation with our buyers and companions is a prerequisite for advancing innovations.” Previously in 2019, the enterprise in the same way partnered with Evolve Additive Solutions to create resources for the Selective Thermoplastic Electrophotographic Process (Step). In SLS, Evonik also acquired Austin based commence-up Structured Polymers Inc. in January this yr.

In accordance to Professor Stefan Buchholz, Govt Director of Evonik Creavis GmbH, Evonik has reportedly been employing the Cubicure Incredibly hot Lithography method to develop “radiation-curing resin units for a when.” This has involved, Professor Buchholz adds, the generation of customized-created “oligomers, specialty monomers and suitable additives.” The very first final result of this collaboration to be shared with the general public is the improvement of versatile polymers for Sizzling Lithography.

The versatile Scorching Lithography polymers from Evonik are a kind of a single-element resin procedure referred to as 1K. With 1K techniques, there is no pre-mixing necessary in the print preparation levels, so they can be applied directly to the printing course of action, and will not diminish promptly above time. The elastomer-like properties reached by these polymers facilitate purposes such as 3D printed sealing, grommets, bellows, shock absorbers, protecting covers and shoe soles.

At Formnext 2019, Evonik and Cubicure are anticipated to share more data about the formulation of this resin. From November 19 by means of the 22, Evonik will be exhibiting in corridor 12.1, stand C71 and Cubicure will be in corridor 11.1, stand D.48.
