Bioceramic scaffolds fabrication: indirect 3D printing combined with ice-templating vs. robocasting
Original language description
Ice-templating combined with indirect 3D printing is proposed as a promising method for preparation of scaffolds with multiscale porosity, including a well-defined interconnected macro-channel network. Robocasting was used as a comparative technique to produce scaffolds with comparable porosity at the introduced macroporosity and the inter-grain microporosity levels. Porosity, phase composition and mechanical stability were measured and compared for bio-scaffolds prepared by both techniques. Comparable total porosities could only be achieved in robocasting by choosing a significantly lower sintering temperature (950 degrees C vs. 1200 degrees C). The compressive strength of robocast scaffolds was significantly greater (6.5 +/- 1.19 MPa vs. 2.3 +/- 1.00 MPa, respectively). However, the increased level of interconnected multiscale porosity coupled to a finer grain size of ice-templated samples sintered at 1200 degrees C (similar to 500 nm vs. 2.5 mu m for robocast parts) could prove to be beneficial for the development of highly porous bioactive scaffolds with enhanced biological performance.
