Authors of a new article in the Journal of the Am Ceram Soc report on a solution to the problem of shrinkage and deformation that occurs during sintering of large and complex parts composed of one type of bioactive glass - 3D-pringed "13-93" bioactive glass. They say the addition of hydroxy-apatite powder, creating a glass-ceramic composite for 3D printing, creates a finished product that retains more of the critical shape and dimensions during sintering than pure powders of the glass.
