A rapid prototyping machine using selective laser sintering (SLS) 3D model slicing. Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design data. [1] [2] Construction of the part or assembly is usually done using 3D printing technology. [3]
RepRap (a contraction of replicating rapid prototyper) is a project to develop low-cost 3D printers that can print most of their own components. As open designs , all of the designs produced by the project are released under a free software license , the GNU General Public License .
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
For example, rapid prototyping was one of the earliest additive variants, and its mission was to reduce the lead time and cost of developing prototypes of new parts and devices, which was earlier only done with subtractive toolroom methods such as CNC milling and turning, and precision grinding, far more accurate than 3D printing with accuracy ...
Such models can then be saved in formats for more convenient exchange with others (such as OBJ for virtual viewing in 3D graphics programs) or manufacturing (such a STL to create a real-life model via a rapid prototyping machine). CAID helps the designer focus on the technical aspect of the design methodology rather than the sketching and ...
3D Systems was founded in Valencia, California, by Chuck Hull, the inventor and patent-holder of the first stereolithography (SLA) rapid prototyping system. Prior to Hull's introduction of SLA rapid prototyping, concept models required extensive time and money to produce.
Through Stratasys, Crump has provided financial support to the SME Bright Minds Mentor Program, affording opportunities for high school students to attend the annual Society of Manufacturing Education (SME) RAPID Conference and Exposition. Stratasys has also donated 3D printers to schools participating in the RAPID event.{{Lulka, Jess.
DesignSpark Mechanical is a 3D computer-aided design (CAD) solid modeling software application. It is licensed as proprietary freeware. It enables users to solid model in a 3D environment and create files to use with 3D printers. Using the direct modeling approach, it allows for unlimited and frequent design changes using an intuitive set of tools.
