Evonik and Cubicure to develop supplies for Scorching Lithography 3D printers

German specialty chemical compounds firm Evonik has entered right into a cooperative settlement with Cubicure to make supplies for its Scorching Lithography expertise. A patented methodology of 3D printing, Cubicure Scorching Lithography processes supplies with larger influence power, toughness and warmth deflection than these usually utilized in commonplace “chilly” SLA processes. Collectively the companions have been creating formulations for the strategy to higher meet the wants of business manufacturing shoppers. They anticipate the primary merchandise of this partnership to be made accessible within the close to future, and have introduced a preview of their findings at November’s Formnext 2019.

“The joint strategic improvement venture with Evonik is already in a sophisticated state,” feedback Robert Gmeiner, CEO and co-founder of Cubicure, including that this newest advance “is a vital constructing block on our approach to secure and scalable additive manufacturing processes.”

What’s Scorching Lithography?

Cubicure was based in 2015 as a spin-off of TU Wien (Vienna College of Know-how). It’s Scorching Lithography course of was found in an try to broaden the fabric selections accessible to widespread SLA 3D printing. Particularly, the group developed a way that will facilitate using excessive viscosity polymers, thereby enhancing the fabric properties of the thinner supplies utilized in SLA. Because the identify of the strategy suggests, Cubicure achieves this by growing the working temperature of its lithography techniques. Relying on the fabric chosen, this may be something as much as a temperature of 120°C.

A heated plate carries skinny layers of fabric into the processing space the place it’s then selectively cured by a precision laser-scanning-system. With this set-up, Cubicure ensures that the temperature of the fabric stays fixed, due to this fact eradicating the standard challenges of working with viscous supplies.

3D printing at Evonik

As a number one specialty polymer enterprise, Evonik is investing closely in the way forward for 3D printing. Not too long ago, the corporate has taken steps to maximise its output of VESTOSINT 3D printable PA12 to satisfy demand, and it has been partnering with 3D printing expertise builders to be the primary so as to add its supplies to their platforms. As Thomas Große-Puppendahl, Head of Innovation Development at Evonik explains, “Our strategic focus is on creating and manufacturing ‘ready-to-use’ high-performance supplies for all related 3D printing applied sciences. Shut cooperation with our clients and companions is a prerequisite for advancing improvements.” Earlier in 2019, the corporate equally partnered with Evolve Additive Options to develop supplies for the Selective Thermoplastic Electrophotographic Course of (STEP). In SLS, Evonik additionally acquired Austin based mostly start-up Structured Polymers Inc. in January this 12 months.

In response to Professor Stefan Buchholz, Govt Director of Evonik Creavis GmbH, Evonik has reportedly been utilizing the Cubicure Scorching Lithography system to develop “radiation-curing resin techniques for some time.” This has included, Professor Buchholz provides, the creation of custom-made “oligomers, specialty monomers and appropriate components.” The primary results of this collaboration to be shared with the general public is the event of versatile polymers for Scorching Lithography.

The versatile Scorching Lithography polymers from Evonik are a kind of one-component resin system known as 1K. With 1K techniques, there isn’t any pre-mixing required within the print preparation phases, to allow them to be utilized on to the printing course of, and received’t diminish shortly over time. The elastomer-like properties achieved by these polymers facilitate purposes comparable to 3D printed sealing, grommets, bellows, shock absorbers, protecting covers and shoe soles.

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