Selective Laser Sintering of Lignin-Based Composites [PDF]
ACS Sustainable Chemistry & Engineering, 2021 Lignin is introduced as a suitable component for selective laser sintering (SLS) of polyamide (PA12) to reduce costs while maintaining or improving processability and performance. Alkali lignin (sourced as a polydisperse, amorphous powder) was used at a volume concentration of up to 60 vol % for three-dimensional (3D) printing of complex, layered ...
