Term
| Any category of electropositive elements that usually have a shiny surface, are generally good conductors of heat and electricity, and can be melted or fused, hammered into thin sheets, or drawn into wires. |
|
Definition
|
|
Term
| A manufacutring process in which the industrial material is made into a liquid. The liquid is then introduced (poured or forced) into a prepared mold of proper design. |
|
Definition
|
|
Term
| Materials that undergo a permanent change in shape or size when subjected to a particular amount of stress. |
|
Definition
|
|
Term
| Liquid resin material that utilizes light (visible and ultraviolet) as a catalyst to initiate polymerization, in which the material cross-links and solidifies. The technique is used by various rapid prototyping technologies. |
|
Definition
|
|
Term
| A common practice that includes clean up and finishing procedures on models after they are removed from a rapid prototyping machine. It may also include mechanical or chemical removal of the support structures, powder removal, and surface finishing. |
|
Definition
|
|
Term
| The first step in manufacturing where raw materials are processed into a usable form for further manufacture. |
|
Definition
|

Definition
|
|
Term
| Basic substance in its natural, modified, or semi-processed state, used as an input to a production process for subsequent modification or transformation into a finished good. |
|
Definition
|
|
Term
| Biological materials that can be replaced. |
|
Definition
|
|
Term
| A process of pressing moist sand around a pattern to make a mold. The pattern is removed, leaving a cavity in the sand. The cavity is the mold that will be filled with liquid metal. The result will be a casting that is identical in shape to the original patter. |

|
|
Term
| A process that removes excess material to change the size, shape, or surface. |
|
Definition
|
|
Term
| A rapid prototyping process that fabricates a part layer-wise by hardening a photopolymer with a guided laser beam. |
|
Definition
|
|
Term
| Processes that remove material to change the size, shape, or surface of a part. There are 2 groups of separating processes: Machining and Shearing. |
|
Definition
|
|
Term
| Process to heat a thermoplastic sheet until it softens and then force the hot a pliable material against the contours of a mold using vacuum pressure. |
|
Definition
|
|
Term
| A process that uses a high speed jet of water emitted from a nozzle under high pressure (10,000-60,000 psi or greater). The advantage of water jet cutting is that it does not create a burr and is a low temperature process. |
