Innovative post processing paves the way for mass production in metal 3D printing
The AutoSmooth project, launched last year by Headmade Materials, AM Solutions – 3D post processing technology, and Neue Materialien Bayreuth, is showing its first promising results with regard to highly efficient processing times and significantly improved surface quality. By 2025, a system will be introduced to the market that will revolutionize the surface treatment of ColdMetalFusion (CMF) parts. With this, AM Solutions provides the “missing link” to make CMF technology – and thus metal 3D printing – suitable for mass production.
The AutoSmooth project, initiated last year by Headmade Materials GmbH in cooperation with AM Solutions – 3D post processing technology and Neue Materialien Bayreuth GmbH, focuses on CMF technology and has made impressive progress. Since the project began, the partners have worked intensively to significantly advance the development of a fully automated process chain for unpacking, depowdering, and surface treatment of ColdMetalFusion parts. The initial results are very promising, bringing industrial implementation within reach.
Fast and efficient green part processing ensures excellent surface quality in the final part
AM Solutions – 3D post processing technology has contributed all its expertise in surface treatment to the development. The result is a system that will significantly improve green part processing. An innovative shot blasting process ensures that the surfaces of the parts are finely depowdered and smoothed in a single operation. Staircase effects are effectively removed, and the surface quality is already so high that in most applications there is no need for an additional, lengthy finishing process after sintering. This saves an enormous amount of time. For example, the process of depowdering and smoothing takes only a few minutes, whereas conventional post processing methods can take several hours.
Integrated 2-in-1 solution with an additional powder recovery system
As part of the AutoSmooth project, AM Solutions once again relies on its proven 2-in-1 principle, combining the two process steps of depowdering and smoothing in just one machine. Additionally, the powder is recovered thanks to an advanced system and can be reused, ultimately resulting in significant cost reductions and conservation of valuable resources. A specialized part clamping solution also ensures the careful handling of sensitive green parts during the process.
CMF technology offers many advantages
ColdMetalFusion technology already allows users to produce high-quality metal parts in series through cost-effective additive manufacturing. The main advantage is that a standard and therefore inexpensive powder bed-based polymer printer is sufficient for printing, making the process an interesting drop-in technology for many companies. The parts do not require support structures, which would need to be laboriously removed after printing. Compared to other binder-based processes, CMF technology also excels, as the green parts are significantly more stable, offering greater process reliability.
“If we now provide the ‘missing link’ in post processing with our new development, CMF technology will take a huge leap forward,” says Dr. Till Merkel, Division Manager Technology at Rösler Oberflächentechnik GmbH. “For the industry, this paves the way for cost-efficient, automated processes that will fully unlock the potential of additive mass production for metal parts and significantly reduce unit costs.” The new system from AM Solutions is expected to be available on the market by 2025.
