In the context of Industrial Additive Manufacturing, the requirements for SLS machines have become more and more stringent, which also means that the plants are becoming larger and larger. Among other things, this poses a major challenge: the efficient and mainly automated feeding of SLS systems becomes necessary. LSS GmbH has developed the Modular Material Processing Solution (MMPS) as a solution for this.
The MMPS is a powder management system for laser-sintering systems. It automates the feeding process of your SLS machine. As soon as the Material Module has been manually filled with powder, the automatic weighing, mixing and feeding of the system takes place in the other modules. This allows for time savings for the machine operator of up to 90% and for the entire filling process of up to 25%.
Thanks to its modular design, the MMPS can be individually adapted to the customers’ requirements. With a complete MMPS system a maximum of four material types (e.g. used, virgin, overflow, recycled) can be processed and several machines can be fed. The software developed by LSS enables intuitive control of the entire system. The MMPS is material-open and can be used with almost all current SLS machines on the market.
At the moment, Material, Mixing, Buffer and Filling modules are available. Together with the Top- and Bottom-Feed Adapters, this enables individual adaptation to the existing printing process. Furthermore, the MMPS offers a feed length of up to 20m. This allows for efficient feeding even if there is no more space available in the direct vicinity of your SLS machine.
Due to the integrated filter system a low-dust operation is realized. Furthermore, the direct contact of the powder with employees and the environment is minimized, which reduces the risk of contamination of the powder. The material batches and relevant environmental influences are measured and logged by the MMPS, which allows a good history and traceability of the mixing and conveying process.
