Enabling Yield Improvement in 3D Printing Process Chain #IMTS40

Wed. September 12| 11:00 AM - 11:55 AM | W192-A

Ever since the first pioneering companies have been able to shape metal powders by means of 3D printing or melting, more and more companies want to supplement their conventional production processes with additive methods. How quickly and comprehensively additive manufacturing of metal parts will be established, depends to a large extent on the yield.

The 3D printing industry is still far from guaranteeing the high reproducibility and reliability known from traditional manufacturing processes. Additive manufacturing has only a fraction of combined know-how compared to conventional subtractive methods. Therefore, it requires a lot of investigation within every step of the process chain to enable optimal part printing. Gaining this process knowledge might take as long as several years. However, the number of iteration loops can be significantly reduced with detailed analysis of materials and processes. It takes significant experience combined with unique technology, to allow for a deeper understanding and detailed monitoring of the majority of process steps, such as material powder characterization, i. e. powder size, form, as well as distribution and compactness analysis, crystallographic analysis, build defects, internal and external surface analysis, internal and external dimensional analysis, and the influence of post build treatments, such as heat treatment. Each of those steps can have a significant impact on the overall yield, therefore, correlating obtained information across each of the process steps can significantly improve overall part performance and reduce development time of the optimal recipe.
