Tool and Die Making, Surface Treatment, and Repair by Laser-based Additive Processes

Abstract This paper explores the possibilities to use laser-based additive processes make, surface treat and repair/remanufacture tools, dies molds for cold working, hot injection molding. The failures encountered in these applications are described. materials used conventionally laser accounted for. properties of made by Laser-based Powder Bed Fusion (L-PBF) as good some cases better than those wrought materials. Shorter cycle time, reduced friction, smaller abrasive wear, longer life benefits L‑PBF Directed Energy Deposition with powder (DED-p) (or Laser Metal powder, LMD‑p, or Cladding, LC). leads higher toolmaking costs shorter lead time. Based on a review conducted investigations, this shows that it is possible design make L‑PBF, functionalize them DED-p (LMD‑p, LC), With efficient operational performance target whole tool cycle, combination LC) has greatest potential working molding tools smallest (due current high costs).
