Lignocellulosic Materials in 3D Printing—From Biomedical Applications to Metal Parts Fabrication

Lignocellulosic-based feedstocks are renewable natural materials that are of high interest in materials chemistry for manufacturing. As polysaccharides, their ability to complex with surfactants or metal ions are derived from some of their ligand function and the presence of hydroxyl and carboxylic groups. Thir use of 3D printing has gained ground as both additive and host matrix and gel materials. In this talk, we will focus on the use of lignocellulosic-based polysaccharides isolated from pulp or directly from the raw fiber: 1) polysaccharide complexes and nano cellulose in SLA 3D printing, and 2) Host hydrogels for metal 3D printing. SEM, X-ray, and tensile-compression properties as 3D printed parts were investigated. Their advantages for improved thermo-mechanical properties and biomedical applications will be evident.
