3D printing body parts
CNET reports on a Belgian company that used a process that uses a laser to melt additive layers of titanium powder to create a solid object from a CAD drawing. In this particular instance, the object is a human jaw bone, replete with integral screw threads and myriad nooks and crannies to foster supporting muscle and nerve growth. All precisely accurate to 1/33rd of a millimeter.
This technology takes what has been a rapid prototyping technology materials like wax, plastics and resins to finished end products of the highest durability (doesn’t get much more durable than titanium…). One can imagine that this process combined with recent regenerative advances to narrow the divide between prosthetic and “replacement” limbs.
