Mechanical properties of components fabricated with open-source 3-D printers under realistic environmental conditions

Authors report that:

 

Open-source self-replicating rapid prototyper, RepRaps are 3-D printers.

Low costs enable mass-scale distributed digital manufacturing in ABS, PLA.

Average tensile strengths of 28.5 MPa for ABS and 56.6 MPa for PLA.

Average elastic moduli of 1807 MPA for ABS and 3368 MPa for PLA.

RepRaps are as mechanically functional as commercial 3-D printers.

 

Anisotropic material properties of fused deposition modeling ABS

Authors report that:

“Tensile strengths and compressive strengths of directionally fabricated specimens were measured and compared with injection molded FDM ABS P400 material. For the FDM parts made with a 0.003 inch overlap between roads, the typical tensile strength ranged between 65 and 72 percent of the strength of injection molded ABS P400. The compressive strength ranged from 80 to 90 percent of the injection molded FDM ABS.”
