Description
technical field [0001] The invention specifically relates to a direct resistance heating device for an additive manufacturing wire feeding process, which belongs to the technical field of electric heating components. Background technique [0002] Additive manufacturing technology, also known as 3D printing technology, is an advanced technology that directly manufactures solid parts by stacking materials layer by layer through CAD design data. Additive manufacturing technology can complete the manufacture of many complex structural parts that are difficult to complete by traditional processing, and greatly reduces the processing steps and construction period. It has been widely used in the development of new products and the production of small batches of complex parts. [0003] Additive manufacturing technology is mainly divided into powder-feeding additive manufacturing and wire-feeding additive manufacturing methods according to the different materials used for deposition...
