RISAn Integrated Dual Ultrasonic Selective Powder Dispensing Platform for Three-Dimensional Printing of Multiple Material Metal/Glass Objects in Selective Laser Melting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a new approach of combining point-by-point selective powder delivery with powder bed fusion for multiple material (metal/glass) components printing. Dual ultrasonic vibration was used to achieve ...
Additive Manufacturing of Polymer-Metal/Ceramic Functionally Graded Composite Components via Multiple Material Laser Powder Bed Fusion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the printing of 3D functionally graded polymer/metal, polymer/ceramic composite components via an ultrasonic vibration-assisted laser-based multiple material powder bed fusion (PBF) is reported. Components ...
Easy-To-Remove Composite Support Material and Procedure in Additive Manufacturing of Metallic Components Using Multiple Material Laser-Based Powder Bed Fusion
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Support structures are always associated with laser-based powder-bed fusion (L-PBF) processes, particularly for additive manufacturing of metallic components of complex geometry with overhang structures and for reducing ...
