Sintering of 3 D ‐Printed Glass/ HA p Composites
We report the sintering of 3 D ‐printed composites of 13‐93 bioactive glass and hydroxyapatite ( HA p) powders. The sintering process is characterized on conventionally produced powder compacts with varying HA p content. A numeric approximation of the densification kinetics is then obtained on the b...

Summary: | We report the sintering of 3
D
‐printed composites of 13‐93 bioactive glass and hydroxyapatite (
HA
p) powders. The sintering process is characterized on conventionally produced powder compacts with varying
HA
p content. A numeric approximation of the densification kinetics is then obtained on the basis of Frenkel, Mackenzie–Shuttleworth, and Einstein–Roscoe models, and optimized sintering conditions for 3
D
‐printed structures are derived. Fully isotropic sintering of complex cellular composites is obtained by continuous heating to 750°C at a rate of 2 K/min for a
HA
p content of 40 wt%. The approach can readily be generalized for printing and sintering of similar glass‐ceramic composites. |
