Preparation and characterization of PLA filaments for FDM 3D printing / Amir Yusuf Mohd Shukri ... [et al.]

Polylactic acid (PLA) is the predominant filament material utilised in fused deposition modelling (FDM) 3D printing. Despite being commonly utilised in FDM 3D printing, the fabrication of PLA filament involves a complex extrusion process that is not widely reported. This study aims to assess the the...
