Abstract A solid freeform fabrication technique is described where powder is deposited layer by layer using electrophotographic printing. In this process, powder is picked up and deposited using a charged photoconducting surface and deposited on a build platform. The paper describes a test bed that was designed and constructed to study the application of electrophotography to solid freeform fabrication. It can precisely deposit powder in the desired shape on each layer. The electric field required to transfer the powder on to the platform (or on to previously printed layers) was studied. A polymer toner powder was used to build small components by fusing each layer of printer powder using a hot compaction plate. (Auth abstract) [References: 12] XX
