Efficient production of customized implants
Hip cup from the powder bed: With the LASERTEC SLM series, DMG MORI creates efficient process chains for the production of medical technology products.
Thanks to its two powerful 600 W lasers, whose scan fields each cover the entire build volume, the LASERTEC 30 DUAL SLM allows build rates of over 90 cm³/h. DMG MORI makes use of this in the example of hip cups, for which the machine tool manufacturer has developed a highly productive manufacturing process. “The application is so interesting because the powder bed process offers us the possibility to economically manufacture even individually adapted hip cups,” explains Dr. Uli Sutor, Key Account Medical Industries at DMG MORI, the motivation behind the project.
Since medical technology products such as titanium implants are subject to the highest quality requirements, it was a top priority for DMG MORI to work out an absolutely process-reliable manufacturing process. Dr. Uli Sutor recalls the various tests: “We tested the stability of sample components in the entire build volume and their relative density – especially at higher assembly rates.” With a relative density of over 99.95 percent in the final component, the tests exceeded expectations, and the bending and stress tests were also consistently successful.
Component accuracy was also guaranteed: “The dynamically adjustable focus diameter was further optimized and is now 50 µm. In addition to the high productivity, this results in a very good surface quality. The active liquid cooling ensures outstanding long-term stability in the process. All ingrowth structures can be realized. Dr. Uli Sutor is satisfied with the entire process: “We achieve the best mechanical properties and build-up rates on the market.”
