Researchers in Switzerland are working on a 3D-printable ink that can mineralize to form a high-strength, lightweight bio-composite that mimics the structure and properties of bone. This “BactoInk” contains bacteria that trigger the production of calcium carbonate (CaCO₃) without the need for the high temperatures necessary for manufacturing ceramics.

And last year, Stryker opened a 156,000 ft² facility for 3D printing in Ireland. It’s the latest investment in the field by the world’s largest orthopedics company, which has been working with additive manufacturing technology for more than 20 years. 3D printing metal joint replacements, for example, allows Stryker to make more porous implant surfaces for better bone fixation.
