Method & Evidence

AimCan ultrafast high-temperature sintering (UHS) be effectively employed for rapid, single-step debinding and sintering of additively manufactured ceramic components, and what are the resulting microstructural and mechanical properties?

MethodExperimental investigation and material processing

ProcedureCeramic components produced via material extrusion were first chemically debound in acetone. Subsequently, these components underwent a single-step thermal debinding and sintering process using ultrafast high-temperature sintering (UHS) for durations ranging from 30 to 120 seconds. The resulting microstructures and densities were analyzed.
