Fabrication of Si-based ceramics using polymer-derived ceramics (PDCs) is gaining popularity. Using this route, preceramic polymers can be shaped in the polymer state and then pyrolyzed to produce different types of ceramics. Cellular ceramics can be manufactured using this technique. Herein, the novel fabrication of cellular ceramics with a two-step process using PDCs is reported. First cellular structures are 3D printed with fused filament fabrication (FFF) using thermoplastic polyurethane and impregnated with preceramic polymer polysilazane. Second, pyrolysis of the impregnated structure produces a self-similar ceramic cellular structure. The impact of 1) catalysts, 2) curing environment, and 3) pyrolysis sequence optimization to form cellular ceramics with fully dense SiOC(N) struts are systemically evaluated. The resultant custom ceramic components can tolerate operating temperatures of 1500 °C and can be manufactured for less than 5% of the cost of competing methods. The ceramic material is shown to be biocompatible and promotes fast cell adhesion. Finally, early-stage cell activation on the SiOC(N) structure is shown to be tunable by adjusting the porosity with this 3D printing to mimic the bone tissue geometry for bone regeneration.\n\n{{Pearce publications notice}}\n\n== Keywords ==\n\n polymer derived ceramics; fused filament fabrication; material extrusion; 3D printing; open-source platform,Additive manufacturing, Fused filament fabrication, Open source 3D printing, 3D printing, open hardware, open source, RepRap, Polymer-derived ceramics, Polysilazanes, preceramic polymers, Thermoplastic polyurethanes\n\n== See also ==\n\n* [[Polymer-derived SiOC Replica of Material Extrusion-based 3-D Printed Plastics]]\n* [[3D Printed SiOC(N) Ceramic Scaffolds for Bone Tissue Regeneration: Improved Osteogenic Differentiation of Human Bone Marrow‐Derived Mesenchymal Stem Cells]]\n* [[Effect of thermoplastic polyurethane filament on the cellular ceramics structures obtained from material extrusion and polymer-derived ceramic]]\n\n== In the News ==\n\n# [https://3dprintingindustry.com/news/scientists-successful-in-slashing-ceramic-3d-printing-costs-by-95-using-novel-approach-194994/ Scientists successful in slashing ceramic 3D printing costs by 95% using novel approach] 3D Printing Industry 72k\n# [https://3dprint.com/284539/3d-printing-news-briefs-9-2-21/ 3D Printing News Briefs] 3D Print 78k\n# [https://hackaday.com/2021/08/30/printing-ceramics-made-easier/ PRINTING CERAMICS MADE EASIER] Hackaday 14.9k\n\n{{Page data\n| title-tag = Fully Dense SiOC(N) Cellular Structures via FFF 3-D Printing\n| keywords = Additive manufacturing, Fused filament fabrication, Open source 3D printing, 3D printing, open hardware, open source, RepRap, Polymer-derived ceramics, Polysilazanes, preceramic polymers, Thermoplastic polyurethanes\n| sdg = SDG09 Industry innovation and infrastructure, SDG10 Reduced inequalities, SDG12 Responsible consumption and production,\n| published = 2021\n| organizations = Free Appropriate Sustainable Technology, Western\n| license = CC-BY-SA-4.0\n| language = en\n}}\n\n[[Category:FAST Completed]]\n[[Category:3D printing]]\n[[Category:DIY]]\n[[Category:Distributed manufacturing]]\n[[Category:Polymers]]\n[[Category:Plastic]]\n[[Category:transport]]\n[[Category:materials]]\n[[Category:Open hardware]]\n[[Category:Open source]]"}
