Special Issue Information

Dear Colleagues,

Over the years, advanced manufacturing processes have been developed and improved in order to reduce costs and make a better use of materials. It is known that 3D-printing processes combine excellent characteristics in terms of customization and waste reduction, in addition to their demonstrated potential of optimization. Furthermore, they are suitable to produce high-performance lightweight parts and/or parts with complex geometries that would require considerable extra work if produced using conventional processes. The introduction of advanced materials in the 3D-printing field involves significant investigation under different aspects, such as recommended process parameters and resulting mechanical properties. Special attention is given to bio-based and natural fiber-reinforced polymers due to their characteristics in terms of processability and performance.

This Special Issue aims to provide the latest developments of polymeric materials for 3D/4D-printing technologies. Studies involving, but not limited to, the convergence of process parameters, experimental characterization of resulting properties, numerical modeling of mechanical behavior, and mechanism-based failure analyses are welcome in this Special Issue.

Some photosensitive resins have poor mechanical properties after 3D printing. To overcome these limitations, a polyurethane acrylate oligomer (PUA) microsphere was prepared using the Pickering emulsion template method and ultraviolet (UV) curing technology in this paper. The prepared PUA microspheres were added to PUA-1,6-hexanediol diacrylate (HDDA) photosensitive resin system for digital light processing (DLP) 3D printing technology. The preparation process of PUA microspheres was discussed based on micromorphology, and it was found that the oil-water ratio of the Pickering emulsion and the emulsification speed had a certain effect on the microsphere size. As the oil-water ratio and the emulsification speed increased, the microsphere particle size decreased to a certain extent. Adding a suitable proportion of PUA microspheres to the photosensitive resin can improve the mechanical properties and thermal stability. When the modified photosensitive resin microsphere content was 0.5%, the tensile strength, elongation at break, bending strength, and initial thermal decomposition temperature were increased by 79.14%, 47.26%, 26.69%, and 10.65%, respectively, compared with the unmodified photosensitive resin. This study provides a new way to improve the mechanical properties of photosensitive resin 3D printing. The resin materials studied in this work have potential application value in the fields of ceramic 3D printing and dental temporary replacement materials. Full article
