Process-Reliable And More Efficient Surface Finish For 3D Plastic Parts
The new media mix from AM Solutions – 3D post-processing technology allows the cost-efficient finishing of a wide variety of 3D-printed plastic components (MJF/SLS) in one single processing step. Irrespective of the size and shape of the work pieces, the process is absolutely stable and produces consistently repeatable finishing results. Time-consuming and costly media changes because of multi-stage processes are no longer necessary. This also helps to eliminate the stocking requirements for different media types. The grinding performance depends on the geometrical complexity of the work pieces. For certain applications, the surface roughness can be reduced from Ra = 15 μm to Ra = 3 μm within 240 minutes
"The composition of the new media mix was developed through numerous processing trials. The result is a product that allows the surface finishing of a broad spectrum of components with different shapes and sizes. Irrespective of whether small, delicate work pieces or large components must be treated, the result is always a highly homogeneous, consistent and repeatable finish", explains Christoph Bätz, Project Engineer at AM Solutions – 3D post-processing technology
The surface finishing of particularly delicate work pieces with complex geometries poses especially demanding post processing challenges and frequently causes problems (photo on the left). In combination with optimized printing methods, the new media mix generates highly homogeneous results for these difficult finishing tasks. At the same time, it minimizes scrap and saves costs (photo on the right).
"Decades of valuable experience allow us to continuously develop new solutions that offer a significant added value for our customers and provide solutions to the challenges they have to face. The perfectly adapted interaction between machine, consumables and process know-how makes the innovative, unique solutions of Rösler and its brand AM Solutions – 3D post-processing technology highly successful", concludes Rainer Schindhelm, Division Manager for the Production of Consumables at Rösler Oberflächentechnik GmbH
For over 80 years, the privately-owned Rösler Oberflächentechnik GmbH has been actively engaged in the field of surface preparation and surface finishing. As global market leader we offer a comprehensive portfolio of equipment, consumables and services around the mass-finishing and shot-blasting technologies for a wide spectrum of different industries. Our range of about 15,000 consumables, developed in our Customer Experience Center and laboratories located all over the world, specifically serves our customers for resolving their individual finishing needs. Under the brand name AM Solutions, we offer numerous equipment solutions and services in the area of additive manufacturing/3D printing. Last-but-not-least, as our central training center, the Rösler Academy offers practical, hands-on seminars to the subjects of mass finishing and shot blasting, lean management and additive manufacturing. Besides the German manufacturing locations in Untermerzbach/Memmelsdorf and Bad Staffelstein/Hausen, the Rösler group has a global network of 15 manufacturing/sales branches and 150 sales agents.
With its latest development of a new media type for post processing of thermoplastic components, printed with the MJF and SLS technology, AM Solutions – 3D post processing technology is further expanding its product portfolio. The new media permits the safe, cost-efficient finishing of 3D-printed components with different shapes and sizes in one single process step and with absolutely repeatable results. This eliminates the time-consuming and costly media changes for different processing stages. In combination with the respective printing know-how, the new media mix generates a perfect, finely structured and highly homogeneous surface finish.
