Method & Evidence

AimCan ceramic stereolithography be used to fabricate biocompatible scaffolds with mechanical properties suitable for bone tissue regeneration?

MethodExperimental research and materials characterization

ProcedureCalcium phosphate nanoparticles were synthesized and suspended in a resin. Scaffolds with triple periodic minimal surface (TPMS) designs were printed using Digital Light Processing (DLP) stereolithography. The printed 'green' bodies and sintered scaffolds were analyzed for morphology, mechanical strength (compressive strength), and volumetric shrinkage. Degradation and biological interaction tests were also performed.
