Abstract
This study presents a novel strategy to construct ceramic structures comprised of microporous filaments using photocurable ceramic/monomer feedstocks containing terpene crystals as sublimable porogens for UV curing-assisted 3D plotting technique. The biphasic calcium phosphate (BCP) feedstock, composed of frozen terpene crystals surrounded by BCP/UDMA walls, could be favorably extruded through a fine nozzle and then effectively photopolymerized by UV light. Thus, green filaments with high shape retention could be obtained. In addition, a number of pores could be created in BCP filaments after removing terpene crystals via freeze-drying and the porosity could be tailored by adjusting terpene content in BCP feedstocks. This approach allowed for the construction of dual-scale porous structures comprising microporous filaments in a periodic pattern, with tailored overall porosities and compressive strengths. Several types of self-supporting structures were also successfully constructed using our approach.
