Belgian chemical company Solvay and SLS 3D printer manufacturer Aerosint have collaborated to research and develop an economically viable solution for the SLS 3D printing of high-performance polymers.

The research agreement intends to address the limited adoption of high-performance polymers like PEEK for powder fusion technologies like SLS. This is due to the cost caused by wasted material powder.

Companies - Years - Solvay - Expertise - Aerosint

Both the companies have been cooperating for over two years, with Solvay providing its material expertise to help Aerosint develop its multi-material SLS platform.

“SLS machines that can process high-temperature-polymers are carefully designed and assembled with sophisticated and expensive components. However, at present, there is a significant operating cost disadvantage during the build, which is the excessive waste of up to 90 percent of ‘used-but-unfused’ powder,” commented Edouard Moens, Managing Director at Aerosint.

Aerosint - Company - Studio - M4KEIT - Group

Established in 2016, Aerosint is a start-up company formed from the Belgian studio M4KE.IT Group, currently developing its patented multi-material 3D printing technology.

The multi-material 3D printing technology operates using a selective powder deposition system, which enables total control over the 3D printing material placement in powder bed fusion printing processes. Key to the technology is the alternate powder recoating system. This allows the selective deposition of two or more powders for a single layer containing more than one material, instead of the single material spreading of traditional recoaters. The powder can be polymer, metal, or ceramic-based.

Aerosint - Technology - Material - Wastage - Part

Aerosint claims the technology can potentially reduce material wastage, and as part of the research agreement with Solvay, this could lead to a cost-effective solution for high-performance polymer SLS 3D printing. Moens explains:

“OUR PATENTED SPATIALLY-SELECTIVE, MULTIPLE-POWDER DEPOSITION SYSTEM UNDER DEVELOPMENT INCORPORATES A NON-FUSIBLE SUPPORT MATERIAL IN EACH LAYER WHERE EXPENSIVE HIGH-PERFORMANCE POLYMERS ARE NOT REQUIRED, THEREBY REDUCING MATERIAL WASTE TO VERY LOW LEVELS.”

This is not the first collaborative research agreement that Aerosint has undergone to develop its...
