Frequently Asked Questions (FAQ)

Rapid Prototyping is the automatic construction of physical objects using additive manufacturing technology. The first techniques for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts.

Rapid Manufacturing, also known as direct digital manufacturing, Instant or On-Demand Manufacturing is a manufacturing process which creates physical parts directly from 3D CAD files or data using computer-controlled additive fabrication techniques without human intervention, also called 3D printing or rapid prototyping. When a small low cost device is used it is also called desktop, or personal manufacturing. The primary distinction between the use of other terms to describe 3D printing is that additive freeform fabrication is solely intended to describe a 3D printed part that is to be used as the final product with minimal post-processing. Whereas other terms used to describe rapid prototyping, additive freeform fabrication and the like are simply alternative ways of describing the 3D printing process itself.

Additive Manufacturing (AM), also known as Direct Digital Manufacturing, is the process of joining materials, such as liquid resin, powders to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. Synonyms: additive fabrication, additive processes, additive techniques, additive layer manufacturing, layer manufacturing, freeform fabrication.

Stereolithography (SL) is a process where high powered ultra-violet lasers are directed into a basin of liquid polymer resin solidifying those areas. The part is created in layers from the bottom up, each layer only thousandths of an inch thick. The result is a precise physical copy of the virtual computer model significantly lower in price than conventional prototyping, and delivered to you in a fraction of the time.
SCICON continues to use the latest in Stereolithography technology to generate solid or flexible, highly detailed functioning parts from your drawings, blueprints, or 3D-CAD files.

Stereolithography was invented by Chuck Hull and introduced by 3D Systems in 1986.

Selective Laser Sintering (SLS®) is an additive manufacturing technique that uses a high power carbon dioxide laser to fuse small particles of plastic powder into three-dimensional objects. The laser selectively fuses powdered material by scanning cross-sections generated from a representation of CAD data on the surface of a powder bed. After each cross-section is scanned, the system lowers the powder bed one layer thickness, applies a new layer of material on top, and repeats the process until the object is completed.

CNC (Computer Numerical Control) is a modern machining method use to perform a wide range of machining tasks on a variety of metal and plastic materials. The primary advantage of CNC machining is that it allows for greatly improved accuracy, efficiency, productivity and safety over other forms of metalworking equipment. Virtually every piece of metalworking equipment is available in the CNC – lathes, drills, milling machines, routers, turret punches, grinders and other high-powered cutting devices.
