Abstract： Two technical routes for the additive manufacturing of cemented carbide cutting tools were reviewed： the powder bed fusion route based on thermal forming，and the forming-debindingsintering based on cold printing of green bodies， followed by debinding and sintering. The powder bed fusion technique might produce cemented carbide cutting tools with near-theoretical density，but issues such as porosity，cracking，decarburization and cobalt evaporation remained. By adjusting parameters such as laser energy density，scanning speed，and powder characteristics，the quality of the printed components might be significantly improved. The forming-debinding-sintering technique might produce cutting tools with excellent surface quality and superior mechanics properties，but challnges such as binder residue and component shrinkage persisted. By optimizing key parameters such as binder type，debinding process，and sintering temperature，the density and mechanics properties of the components might be enhanced. Additionally， heat treatment processes such as vacuum sintering，hot pressing，and hot isostatic pressng might further eliminate internal defects in the materials，thereby improving the overall performance of the cutting tools.
