In the three-dimensional printing process of ceramic with low-angle structures, additional supporting structures are usually employed to avoid collapse of overhanging parts. However, the extra supporting structures not only affect printing efficiency, but the problems caused by their removal are also a matter of concern. Herein, we present a ceramic printing method, which can realize printing of unsupported multi-scale and large-span ceramics through the combination of direct ink writing and near-infrared induced up-conversion particles-assisted photopolymerization. This printing technology enables in-situ curing of multi-scale filaments with diameters ranging from 410 µm to 3.50 mm, and ceramic structures of torsion spring, three-dimensional bending and cantilever beam were successfully constructed through unsupported printing. This method will bring more innovation to the unsupported 3D manufacturing of complex shape ceramics.
Auxiliary supports are commonly introduced to avoid collapse in three-dimensional (3D) ceramic printing with low-angle structures, which could bring concerns of complex process and unsatisfying material utilization, limiting the improvements of printing efficiency. To overcome this limitation, this paper presents a simple ceramic printing method, which realizes printing of unsupported multi-scale and large-span ceramics through the combination of direct ink writing (DIW) and up-conversion particles-assisted photopolymerization (UCAP) process under near-infrared (NIR) irradiation. This printing technology enables in-situ curing of multi-scale filaments with diameters ranging from 410 µm to 3.50 mm, and successfully constructed ceramic structures of torsion spring, three-dimensional bending and cantilever beam through unsupported printing. This method will bring more innovation space to the high-throughput and unsupported 3D manufacturing of complex shape ceramics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
