Abstract Scope |
Additive manufacturing of metals offers innovative solutions to the problems faced during traditional casting and fabrication methods, particularly in producing metal platforms for removable partial dentures (RPDs). However, the presence of dendritic grain structure in 3D-printed metal microstructures limits its application in the denture field. This study explores the 3D printing of Ti-6Al-4V alloy powders mixed with ~1 vol% TiO2 nanoparticles by directed energy deposition (DED) technique. Ti-6Al-4V metal powders and TiO2 nanoparticles were uniformly mixed using a ball-milling approach. Cubic samples were printed using the BeAM Modulo 250 V1.0 DED metal 3D printer, and their microstructural changes were analyzed with optical and scanning electron microscopes. The results show that incorporating nanoparticles resulted in an equiaxed grain structure in the build direction, indicating a significant enhancement in the mechanical properties of the RPDs. This improvement potentially eliminates the need for post-processing techniques such as heat treatment and hot isostatic pressing. |
