New additive manufacturing process uses water-based metal paste

Additive manufacturing (AM) is a novel process that creates parts by building upward from a base, layer by layer, until a complete form is finished. It is a process that traditionally has been viewed as a slow, methodical way to produce complex parts with internal features, parts that cannot be created using other manufacturing technologies.

Rapidia, Vancouver, has introduced a new AM system to 3D print strong, complex metal parts for prototyping and end-use applications using a water-based metal paste, rather than the powders and wires typically used in AM applications. Recognizing that existing “office-friendly” metal 3D printers typically require a chemically intensive and lengthy debinding process, a procedure that treats the finished parts in a chemical solvent, the Rapidia […]
