Mold SDM is an additive-subtractive layered manufacturing process that builds fugitive wax molds for use in secondary processes, such as gelcasting. Several build techniques have been developed to improve part quality and process efficiency. By decomposing models into non-planar layers surface quality is improved and fewer layers are required. The range of buildable features is improved by a tw...

AlN/epoxy composites with high thermal conductivity were successfully prepared by infiltrating epoxy into AlN porous ceramics which were fabricated by gelcasting of foaming method. The microstructure, mechanical, and thermal properties of the resulting composites were investigated. The compressive strengths of the AlN/epoxy composites were enhanced compared with the pure epoxy. The AlN/epoxy co...

The stray grain defect is often found at the platform in process of directional solidification single crystal blades because local undercooling easily occurs this area. A variable wall thickness mold based on stereolithography and gelcasting technology was proposed to solve platform. influence temperature field during studied via simulation. numerical simulation results show that can effectivel...

Replamineform Inspired Bone Structures (RIBS) using multi-piece molds and advanced ceramic gelcasting technology.Abstract A new technology was developed for quickly, simply, and affordably creating Replamineform Inspired Bone Structures (RIBS) that combines multi-piece mold manufacturing for creating complex macroscale geometries with advanced ceramic gelcasting technology for controlling micro...

Hydroxyapatite (HA) is widely applied as bone graft material due to its osteoconductive potential and well-established biocompatibility. In this work, macroporous hydroxyapatite structures made through foaming of aqueous suspensions and gelcasting were tested for in vivo osteointegration. These foams are composed of a three-dimensional array of spherical pores with diameters of approximately 10...
