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.
Chuck Hull (Charles W. Hull; born May 12, 1939) is an American inventor who is the co-founder, executive vice president and chief technology officer of 3D Systems. [1] [2] He is one of the inventors of the SLA 3D printer, the first commercial rapid prototyping technology, and the widely used STL file format.
Stereolithography (SLA or SL; also known as vat photopolymerisation, [1] optical fabrication, photo-solidification, or resin printing) is a form of 3D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photochemical processes by which light causes chemical monomers and ...
Revenue. $82.5 million (2021) [1] Number of employees. 500. Website. formlabs.com. Formlabs is a 3D printing technology developer and manufacturer. The Somerville, Massachusetts-based company was founded in September 2011 by three MIT Media Lab students. The company develops and manufactures 3D printers and related software and consumables.
3D printing filament is created using a process of heating, extruding and cooling plastic to transform nurdles into the finished product. However, unlike a 3D printer, the filament is pulled rather than pushed through the nozzle to create the filament. The diameter of the filament is defined by the process that takes place after the plastic has ...
Austin-based Icon has made quite a name for itself in the budding 3D printing construction industry. In 2022, the company unveiled a 2,000-square-foot luxury home with printed walls in Austin.

[4][5] The company is incorporated in Israel. [6] Engineers use Stratasys systems to model complex geometries in a wide range of polymer materials, including: ABS ...
Developed by. 3D Systems. Initial release. 1987. Type of format. Stereolithography. STL is a file format native to the stereolithography CAD software created by 3D Systems. [3][4][5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography. [6] An STL file ...
