Direct and Selective Electroless Metallization of low-cost 3D Printed Composite Filaments Loaded with Metals to Enhance Surface Properties

The selective and direct metallization (electroless plating) of low-cost FFF 3D printed objects will be investigated in this research project. After 3D printing, the workpiece will be directly subjected to the electroless plating process (skipping the etching and catalyzation steps). We show that conventional low-cost conductive composite filaments loaded with metals can be used for direct plating. We will not only forego pre-treatment (i.e., harsh chemical etching), but we will also employ a formaldehyde-free (green) electroless copper solution, making this a major step forward in sustainable plastic metallization. Allowing complex and functional devices printed on a low-cost commercial desktop 3D printer to be rapidly and selectively metallized without modification is a significant advancement in lowering the cost and manufacturing complexity of 3D printed parts, increasing efficiencies, and reducing weight, and thus represents a turning point in the technology’s adoption. VPMR is developing custom 3-D products development and printing service, currently based on polymer FDM process. It is VPMR’s strategic objective to expand into low-cost 3-D printed metal products, based on the use of composite filaments, and later also debinding and sintering capability (such as currently available in system like XERION’s Fusion Factory).
