Laser Chemical Vapor Deposition (LCVD) is a promising rapid prototyping and manufacturing process that deposits metals and ceramics by local heating of a substrate with a laser. Even though many LCVD process planning characteristics are shared with those of more common Solid Freeform Fabrication (SFF) technologies, LCVD process planning requires new efforts due to its unique characteristics. Un...

In this paper, the electrospray technology is used to easily deposit the glass frit into patterns at a micro-scale level. First, far-field electrospray process was carried out with a mixture of glass frit in the presence of ethanol. A uniform, smooth, and dense glass frit film was obtained, verifying that the electrospray technology was feasible. Then, the distance between the nozzle and the su...

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...

Electrospark deposition (ESD) was studied to investigate the possibility of forming non-equilibrium microstructures in Al alloy systems. The results have demonstrated that the level of supersaturation is system-dependent. The Al-10 wt% Mg system exhibited a complete supersaturation, while the Al-Si system had a supersaturation level reaching about 1wt%. The ESD process was also used to demonstr...

For an evaporating colloidal suspension in which the evaporation velocity exceeds the sedimentation velocity, particles will accumulate at the solvent-air interface. If neither diffusion nor convection can disperse this accumulation, it is expected to grow into a colloidal multilayer several microns thick. We observe that the thickness of colloidal crystals vertically deposited from 1 mum diame...
