A review: Challenges stand off for tooling material in AM field

Abstract

Direct metal laser sintering (DMLS) is one part of additive manufacturing (AM) emerges as rapid prototyping
(RP)technique and it is making three dimensional product or parts directly from computer aided data (CAD) without
intervening of tooling or human effort. Cl50WS material is hot tool steel material which widely accepted in additive
manufacturing field. Nowadays, conventional cooling in die and mould manufacture have been shifted to new developing
technique conformal cooling. Cooling is provided in die or mould by drilling in conventional method which provides uneven
cooling, but now conformal cooling provide uniform cooling in cavities of die or mould. Die and mould has own special
characteristic like high mechanical properties, wear resistance, dimensional accuracy and good surface finish. These
characteristic can be fulfill when die and mould would be made by selection of proper parameter of machine. Hence, it is
very essential to conducted optimization of DMLS machine for CL50WS material.
