A Redditor shared on the platform using a ‘bone-simulating’ filament to 3D print a sample test rib for planning surgeries. User u/PectusSurgeon said on r/3Dprinting that they will also use TPU to print simulated cartilage but will still have to work out how to attach it to the PLA bone and “make it behave like the real thing.”
It seems that the Redditor used the SimuBone Bone Modeling Filament created by 3DXTech to print the test rib, and according to the user’s feedback, it mostly feels like the real thing. “My main concern was whether it would melt from the heat generated by friction with the saw,” u/PectusSurgeon said in reply to one of the comments. “At 75% infill it’s pretty rigid but still has some flex to it. Cartilage will be trickier but there are lots of kinds of TPU that have different amounts of elasticity.”
