Evaluation of the surface roughness and dimensional accuracy of low-cost 3D-printed parts made of PLA-aluminum.

Fused deposition modeling (FDM) is currently used in several fields, such as architecture, manufacturing, and medical applications. FDM was initially developed to produce and create prototypes, but the expense appears excessive for producing final products. Nevertheless, in this day and age, engineers have developed a low-cost 3D printer.
