Transient liquid-phase infiltration of a powder-metal skeleton
… infiltration and full-density sintering. Fabrication of direct metal parts with complex geometry is possible using TLI in conjunction with Solid Freeform Fabrication (SFF) processes such as Three-Dimensional Printing, which produce net-shape skeletons of powdered metal directly from CAD …

Nanotube reinforced thermoplastic polymer matrix composites
… The two studies demonstrate the effect of solid freeform fabrication (SFF) and chemical functionalization on anisotropy and limited reactivity, respectively. Both studies showed mechanical property improvements. The alignment study demonstrates a maximum increase of 93% in tensile modulus …

Fabrication of engineered ceramic components by the slurry-based three dimensional printing process
… engineered ceramic components. The process is a solid freeform fabrication (SFF) technique that builds components directly from a computer CAD file on a layer-by-layer basis. Solid-liquid interactions play a primary role in the process physics of each stage of the process. The formation of the …

Analysis of functionally graded material object representation methods
Solid Freeform Fabrication (SFF) processes have demonstrated the ability to produce parts with locally controlled composition. To exploit this potential, methods to represent and exchange parts with varying local composition need to be proposed and evaluated. In modeling such parts efficiently, any …

A surface texture modeling system for solid freeform fabrication
Solid Freeform Fabrication, SFF, is a set of manufacturing processes that fabricates parts as a bonded stack of individual layers. The Three Dimensional Printing process, 3DPTM process, is an SFF technology developed at MIT. It builds layers by ink jet printing binder onto the surface of a bed of …

Rapid tooling by integration of solid freedom fabrication and electrodepostion
Rapid tooling (RT) techniques based on solid freeform fabrication (SFF) are being studied worldwide to speed up the design-production cycle and thus keep manufacturers at a competitive edge. This dissertation presents a novel rapid tooling process that integrates SFF with electrodeposition to …
