Electron Beam Solid Freeform Fabrication of Metal Parts
A novel method for near-net-shape fabrication of large, complex metal parts without the need for specific tooling is described. Parts are built up in a layer-by-Iayer fashion by feeding raw material in wire form into a ...
In-Situ Property Measurements On Laser-Drawn Strands Of SL 5170 EPOXY and 5149 Acrylate
Material behavior plays a significant role in the mechanics leading to internal stresses and, potentially, to distortion (curling) of parts as they are built by stereolithography processes that utilize photocuring resins. ...
A 3D Print Process For Inexpensive Plastic Parts
Many of the currently available RP-Systems are suitable for building design models of arbitrarily shaped parts. However, most of these RP processes use sophisticated and expensive equipment which is not well suited for ...
Production of Injection Molding Tooling with Conformal Cooling Channels using The Three Dimensional Printing Process
Three Dimensional Printing is a desktop manufacturing process in which powdered materials are deposited in layers and selectively joined with binder from an ink-jet style printhead. Unbound powder is removed upon process ...
