Wear of ultra-high molecular weight polyethylene manufactured with laser powder bed fusion
… in this work, we use laser-powder bed fusion (L-PBF) to manufacture UHMWPE specimens. We print and post-process cylindrical pin specimens and perform pin-on-disc wear testing against stainless steel countersurfaces. We measure wear as a function of sliding distance for 3D-printed UHMWPE specimens …
