Evonik, a leading German chemical company,has announced a partnership withEvolve Additive Solutionsto advance the range of thermoplastic materials for Evolve’sSelective Thermoplastic Electrophotographic Process(步骤)技术。
“STEP has been developed for volume manufacturing so offering the widest range of thermoplastic materials to our customers is a critical element for production,” stated Steve Chillscyzn, CEO of Evolve Additive Solutions.
“The joint development agreement with Evonik allows us to broaden the spectrum of STEP materials to include materials currently accepted by OEMs from additive manufacturing, but more importantly to debut a whole new set of materials opening up more applications that can take advantage of everything additive manufacturing offers.”
Optimizingthermoplastics for 3D printing
Since its founding in 2007, Evonik has produced a range of specialty polymer powders such as PEBA and PEEK. The company is also known for its Polyamide 12 (PA 12) range of powder called VESTOSINT, which can be customized for SLS, HSS (High Speed Sintering), and Multi Jet Fusion 3D printing.The collaboration with Evolve will initially focus on PA 12 and PEBA polymers.
PA 12 protects against chemical and water as well as being tough and resistant to stress, fatigue cracking and has durability over a wide temperature range from -40°C to 90°C. Due to its strong mechanical and chemical properties, this material is used for automotive and lightweight design as well as in oil and gas pipelines.
Recently, the company announced theclosure of its Witten plantto establisha new€400 million plant for the production of PA12.Evonik has also been strengthening its additive materials offerings with the acquisition of Austin-based startupStructured Polymers, a producer of colored powders for SLS, earlier this year.
“Evolve’s entirely new technology approach will allow us to expand the range of applications of our high-performance materials, which are produced through a unique production process,” added Thomas Grosse-Puppendahl, the Head of the Additive Manufacturing Innovation Growth Field at Evonik.”
“With more than 20 years of experience in 3D printing, we will also develop a wider range of customized material formulations to unlock the full potential of the STEP technology.”
Taking STEP beyond Alpha
Evolve Additive, an OEM which started out life in Stratasys’ R&D labs, officiallyspun out from the companyin 2017, developingSTEP technology. This was unveiled asa new, high-speed plastics 3D printing process said to be up to “50 times faster than the next fastest AM plastics technology.”
STEPis based on the proprietary technology behind most photocopiers and laser printers andhas been developed to process thermoplastic materials quickly, offering isotropic properties in X, Y, and Z, and rival the surface finish of traditional methods.The last few years has seen Evolve focus on the commercialization and industrial application of STEP.
In September 2018, the companyreceived $19 million in investmentto help the company achieve a Beta stage rollout of its STEP 3D printers. This was followed in November by news ofa partnership with Kodakto develop Evolve’s 3D printing technology for commercial release in 2020.
Presently, STEP is still in the alpha development phase and is expected to be ready for the market by the end of 2020.
