STL (file format)

STL (file format)
Example of STL vs CAD format STL (STereoLithography) is a file format native to the stereolithography CAD software created by 3D Systems. STL is also known as Standard Tessellation Language.[1] This file format is supported by many other software packages; it is widely used for rapid prototyping and computer-aided manufacturing. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. An ASCII STL file begins with the line: solid name where name is an optional string (though if name is omitted there must still be a space after solid). facet normal ni nj nk outer loop vertex v1x v1y v1z vertex v2x v2y v2z vertex v3x v3y v3z endloop endfacet where each n or v is a floating point number in sign-mantissa 'e'-sign-exponent format, e.g., "-2.648000e-002" (noting that each "v" must be non-negative). endsolid name

RepRap Project RepRap version 1.0 (Darwin) RepRap version 2.0 (Mendel) First part ever made by a Reprap to make a Reprap, fabricated by the Zaphod prototype, by Vik Olliver (2006/09/13) The RepRap project is a British initiative to develop a 3D printer that can print most of its own components.[1] RepRap (short for replicating rapid prototyper) uses an additive manufacturing technique called Fused filament fabrication (FFF) to lay down material in layers; a plastic filament or metal wire is unwound from a coil and supplies material to produce a part. As an open design, all of the designs produced by the project are released under a free software license, the GNU General Public License.[2] History[edit] All of the plastic parts for the machine on the right were produced by the machine on the left.

Fused deposition modeling Fused deposition modelling: 1 – nozzle ejecting molten plastic, 2 – deposited material (modeled part), 3 – controlled movable table An ORDbot Quantum 3D printer. Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications. FDM works on an "additive" principle by laying down material in layers; a plastic filament or metal wire is unwound from a coil and supplies material to produce a part. The technology was developed by S. The term fused deposition modeling and its abbreviation to FDM are trademarked by Stratasys Inc. History[edit] Fused deposition modeling (FDM) was developed by S. Process[edit] The model or part is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle. A plastic filament or metal wire is unwound from a coil and supplies material to an extrusion nozzle which can turn the flow on and off. See also[edit]

A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.

Drukarka 3D pod strzechą. "Rewolucja na miarę internetu" Reporter "Polski i Świata" poprosił doktora Przemysława Siemińskiego z Politechniki Warszawskiej o wydrukowanie zabawki - klocka lego. Najpierw trzeba wykonać projekt, potem przełożyć go do drukarki - i czekać. - Drukowanie 3D polega na wartstwowym nakładaniu materiału. Jest to technologia przyrostowa, w przeciwieństwie do technologii ubytkowych, jak toczenie czy frezowanie, gdzie materiał jest zabierany - mówi dr Siemiński. Studenci Politechniki Warszawskiej, którzy zaprezentują ciekawy i nowatorski pomysł, mogą w ramach zaliczeń drukować na przykład części do samochodów. Drukarka 3D: "nieskończone możliwości" Jak mówi dr Siemiński, drukowano już koła zębate do pasów bezpieczeństwa albo przyciski do amerykańskiego samochodu, których nie można już dokupić. Ale to nie wszystko. - To jest proste, a możliwości nieskończone. "To będzie przełom" Na razie sprzętem, który pozwala drukować w 3D, dysponują głównie specjalne firmy lub uczelnie, ale to się zmienia. Autor: MAC//bgr / Źródło: tvn24
