Pushing the art of the possible.
With key partners, our systems are being used to accelerate the development of new LPBF capabilities, to include:
Selective Laser Ablation and Melting (SLAM™)
SLAM is a hybrid process that combines selective laser melting with in situ laser ablation using two different laser sources, for all-optical (non-mechanical) additive + subtractive processing. The patent-pending technique allows in situ ability to:
produce smooth side and top walls,
improve sharpness of edges/corners,
produce fine thin walls and accurate internal features, and
reduce residual stresses as built.
Process control and applications development are ongoing, led by Universal Technology Company with University of Dayton Research Institute's support. The process is expected to be best suited for smaller parts requiring very high complexity with minimal post-processing. OpenAdditive's PANDA platform can be configured with subtractive laser for SLAM R&D. Contact us fto discuss potential configurations, applications, or get a quote.
Spatio-Temporal Redistribution of Energy for Additive Manufacturing (STREAM™)
We're working with partners to evaluate, develop, and integrate beam-shaping technologies (together, dubbed as STREAM) to control the dynamics of laser-material interaction, in order to promote microstructural phases of interest (or inhibit undesirable ones) and/or reduce defects such as spatter and cracking. The overarching goal is dynamic control of beam shape (or multiple beams) to better melt/sinter difficult materials for demanding applications. Both commercially-available and custom optics are under study. Our PANDA system is ideal for researchers interested in developing their own solutions in this area.
Multi-Material Powder Bed Deposition
We are interested in capability to produce structures with compositional grading, enabling metal AM parts with strong metallurgical bonding across regions with different materials. Potential applications include (1) parts with hard metal/ceramic surfaces for improved wear, (2) selective regions of high-temp or oxidation resistant alloys for parts with areas exposed to extreme environments, and (3) functional grading to meet conductivity or shielding requirements. Development by Universal Technology Company is ongoing for full automation of grading in three dimensions. Contact us to discuss potential applications.
