Abstract:
Sinter-based additive manufacturing of metallic materials offers advantages in terms of design and efficiency but poses environmental concerns due to the use of chemicals and the generation of pollutant gases during the elimination of binders which are harmful to the environment. To improve this problem, the study of biopolymeric binders derived from renewable sources is proposed. This work explores composite extrusion modelling of metallic or metal-ceramic alloys using biopolymers to produce environmentally friendly feedstocks. Comprehensive evaluation of biopolymer blends based on poly lactic acid and polyvinyl alcohol were carried out for their use as binders. A study of critical solidity loads, microstructural, rheological characterisation, densification, and homogenisation, studies were performed.
