Sumary of New way to 3D-print custom medical devices to boost performance and bacterial resistance:
- Similarly, single-material 3D printing methods have design limitations that cannot produce a bespoke device with multiple biological or mechanical functions..
- For this study, the researchers applied a computer algorithm to design and manufacture — pixel by pixel — 3D-printed objects made up of two polymer materials of differing stiffness that also prevent the build-up of bacterial biofilm..
- By optimising the stiffness in this way, they successfully achieved custom-shaped and -sized parts that offer the required flexibility and strength..
- Current artificial finger joint replacements, for example, use both silicone and metal parts that offer the wearer a standardised level of dexterity, while still being rigid enough to implant into bone….
