Abstract This work presents the results of a preliminary study in which a sodium aluminosilicate geopolymer powder was shaped into a lattice component by additive manufacturing and successfully employed as a structured heterogeneous catalyst for biodiesel production. The processing and the structural characterization of the 3D printed body and the chemical conversion tests are described and discussed.

Abstract By taking advantage of the multi-functional properties of preceramic polymers, their transformation into ceramic material at low sintering temperatures and the processing capabilities of polymer manufacturing processes, mullite components were fabricated by additive manufacturing. A photocurable silicone preceramic polymer resin containing alumina particles was shaped into complex structures via Digital Light Processing. Dense and crack-free, highly complex porous mullite ceramics were ...

Abstract Waste glass-based cellular geopolymers with total porosity about ~55 vol%, thermal conductivity of ~0.21 W/mK, and compression strength of ~7.3 MPa were successfully produced by a direct foaming technique using hydrogen peroxide (chemical pore-forming agent) in combination with Triton X-100 (stabilizing agent). Thermal treatment of these porous geopolymers at 700–900 °C resulted in a significant increase in volume (secondary foaming). Interconnected pores with a wide range of sizes, ran...

Abstract Thermoplastic filaments for Fused Deposition Modeling fabrication of mullite ceramic components were produced from a polymethylsiloxane ceramic precursor, γ-Al 2 O 3 powder and ethylene vinyl acetate (EVA) as an organic, elastomeric binder. Two micron-sized γ-Al 2 O 3 powders with different particle size distributions were used. Both type of powders could be successfully 3D printed, however γ-Al 2 O 3 with finer particle size resulted in better quality of printed parts with much smoothe...

Abstract A systematic study of the additive manufacturing of complex ceramic objects was carried out using two different Digital Light Processing (DLP) approaches, the "bottom-up" and "top-down" ones, employing the same projector as light source and a photosensitive Al 2 O 3 -based ceramic slurry. Cylindrical periodic architectures having different macro-porosity, as well a bulk (dense) component in the form of a disk, were designed and additively manufactured with the two printers employing sim...

Abstract 2 Hardystonite scaffolds produced by ceramization of 3-D printed preceramic filled polymer were impregnated with chitosan solutions, later neutralized into physical hydrogels. Hardystonite bioceramic and chitosan physical hydrogel were chosen for their interesting biological properties as potential bone substitutes. Five impregnation protocols, differing in impregnation vacuum, chitosan concentration, chitosan to hardystonite mass ratio and base used for chitosan gelation were studied. ...
