Seamless Manufacturing and Remanufacturing for Foundry Industry via Laser-based 3D Printing and Surface Cladding
Abstract
he goal of this project is to develop cost effective technologies for rapidly building and repairing various molds and toolings used in the foundry industry such as sand molds and also achieving bimetallic cladding on various metallic alloys. In order to achieve this goal the project will aim at i) establishing the capabilities for rapid 3D printing of cores with conformal cooling lines, ii) developing a seamless strategy for rapid repair of various toolings and demonstration, iii) determining the range of possible materials for bimetallic cladding and develop a design of experiment, iv) cladding a representative sample of the most promising bimetallic cladding materials and optimize the microstructure for wear resistance and v) characterizing the resultant microstructure, wear resistance and mechanical properties. Both the powder bed and directed energy deposition techniques will be used and automatic reconstruction of part drawings from actual legacy or damaged parts and an automatic laser scanning path procedure will be developed.
