Abstract

Process stability in directed energy deposition is not sufficiently high to achieve high repeatability in deposition results due to residual heat. This paper summarizes the correlation between baseplate temperature and deposition result in DED in order to control heat condition around melt pool. The baseplate temperature certainly has a high correlation with porosity rate and amount of melting in deposited objects.
