| Additive Process | The process of creating an object by adding small pieces or layers together to make a final product. |
| Ceramic | Of or relating to the manufacture of any product (as earthenware, porcelain, or brick) made essentially from a nonmetallic mineral (as clay) by firing at a high temperature. |
| Codes | A systemized body of laws; a set of principles, as of ethics. |
| Composite | Solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole; especially, a structural material made of plastic within which a fibrous material (as silicon carbide) is embedded. |
| Decision Matrix | A tool for systematically ranking alternatives according to a set of criteria. |
| Finishing | Machining a surface to size with a fine feed produced in a lathe, milling machine, or grinder. |
| Forming | A process that changes the size and shape of a material by a combination of force and a shaped form. |
| Liability | Anything for which a person is legally bound or responsible. |
| Manufacturing | To make into a product suitable for use; to make from raw materials by hand or by machinery; to produce according to an organized plan and with division of labor. |
| Material | The elements, constituents, or substances of which something is composed or can be made; matter that has qualities which give it individuality and by which it may be categorized. |
| Mechanical Properties | Those properties of a material that reveal the elastic and inelastic reaction when force is applied, or that involve the relationship between stress and strain; for example, the modulus of elasticity, tensile strength, and fatigue limit. |
| Metals | Any of various opaque, fusible, ductile, and typically lustrous substances that are good conductors of electricity and heat. |
| Physical Properties | Properties other than mechanical properties that pertain to the physics of a material and can usually be measured without the application of force. |
| Polymers | Any of numerous natural and synthetic compounds of usually high molecular weight consisting of up to millions of repeated linked units, each a relatively light and simple molecule. |
| Product Life Cycle | Stages a product goes through from concept and use to eventual withdrawal from the marketplace. |
| Raw Material | Crude or processed material that can be converted by manufacture, processing, or combination into a new and useful product; something with a potential for improvement, development, or elaboration. |
| Recycling | Returning to an original condition. The extraction and recovery of valuable materials from scrap or other discarded materials. |
| Subtractive | Processes that remove material to change the size, shape, or surface of a part. There are two groups of separating processes: machining and shearing. |
| Synthetic | Produced by the combining of parts or elements to form a whole, rather than of natural origin; not real, artificial. |
