Hybrid manufacturing method comprising an additive manufacturing step and a product resulting from such a method
A hybrid manufacturing method comprising providing a base member, the base member comprising a metallic portion provided with a coating; providing a surface treatment to all or part of the coating, the surface treatment comprising a mechanical, a chemical and/or a physical treatment, to obtain a treated base surface; and forming an additional part onto the treated base surface by additive manufacturing.
1 . A hybrid manufacturing method comprising:
providing a base member, the base member comprising a metallic portion provided with a coating, the coating comprising resin, an e-coat primer, and a top-coat layer;
providing a surface treatment to all or part of the coating, the surface treatment comprising thermal or chemical treatment, to obtain a treated base surface to provide adhesive features to at least a portion of the coating; and
forming an additional part onto the treated base surface by additive manufacturing.
2 . The hybrid manufacturing method of claim 1 , wherein the surface treatment comprises removing at least in part the coating.
3 . A hybrid manufacturing method comprising:
providing a base member, the base member comprising a metallic portion provided with a coating, the coating comprising an e-coat primer and a top-coat layer;
providing a surface treatment to all or part of the coating comprising removing all or part of the top-coat layer only, the surface treatment comprising thermal or chemical treatment, to obtain a treated base surface; and
forming an additional part onto the treated base surface by additive manufacturing.
4 . The hybrid manufacturing method of claim 1 , wherein the surface treatment comprises a predetermined pattern.
5 . The hybrid manufacturing method of claim 1 , comprising, before forming the additional part, providing a layer of adhesive material onto the treated base surface.
6 . The hybrid manufacturing method of claim 1 , comprising, after forming the additional part, a post-treatment.
7 . The hybrid manufacturing method of claim 1 , wherein the additional part is made of polymeric material.
8 . The hybrid manufacturing method of claim 1 , wherein the base member is all or part of a vehicle chassis or of a vehicle body, and the additional part is a bracket, a fastener, a mounting part, or an informative element.
