3D Printing of Porous Mullite From Sol–Gel Photocurable Powder‐Free Ink
Porous mullite (AlVI2(AlIV2+2xSi2−2x)O10−x, where x ranges between 0.17 and 0.57) structures were fabricated by integrating sol–gel chemistry with digital light processing (DLP), enabling complex geometries with coupled micro‐ and macroporosity. The method uses a powder‐free, low‐viscosity photocurable sol–gel ink (0.0...
