STL (file format) - Wikipedia (US)
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. Binary files are more common, since they are more compact.[2] 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 endsolid name White space (spaces, tabs, newlines) may be used anywhere in the file except within numbers or words.

STL 2.0 May Replace Old, Limited File Format Since soon after it was developed, people in the rapid prototyping field have talked about replacing the industry-standard STL file format. Yet it has endured for 22 years. Still, the pressure for change builds. Frequently asked questions on 3D printing What is 3D printing? 3D printing is a prototyping process that makes it possible to create an actual object from a 3D file. The object is formed by applying successive layers of solid material.

Glass ExOne now offers digital part materialization in 100% recycled (and recycleable) soda-lime glass. The fine glass powder is glued together, layer by layer with a binder and sintered in a kiln. The material is porous, opaque and fragile and feels coarse to the touch. The glass material systems are best used for art sculptures and other decorative objects.

Technical source:StereoLithography Interface Specification, 3D Systems, Inc., October 1989 An StL file consists of a list of facet data. Each facet is uniquely identified by a unit normal (a line perpendicular to the triangle and with a length of 1.0) and by three vertices (corners). The normal and each vertex are specified by three coordinates each, so there is a total of 12 numbers stored for each facet.

Free 3D Models for 3D Printing Submit additions and corrections to the 3D Printing Directory These websites are the major repositories for finding and downloading free 3D models for use with a 3D printer. The sites files range from very simple free 3D models to very complex 3D models. 3D Content Central 3D ContentCentral hosts free 2D and 3D CAD files from engineers and firms.

Source File Types for Quotes / Prototypes ProtoCAM can accept several types of files as input data. We accept files from any CAD package, provided the geometry is exported into an STL (stereolithography) file format. The STL file format is standard for the Rapid Prototyping industry. This format approximates the surface of a parametric solid model with a mesh of triangles. For detailed instructions, please consult our instructions for exporting STL files from various CAD packages. Stereolithography An SLA produced part Stereolithography (SLA or SL; also known as optical fabrication, photo-solidification, solid free-form fabrication and solid imaging) is an additive manufacturing or 3D printing technology used for producing models, prototypes, patterns, and production parts up one layer at a time by curing a photo-reactive resin with a UV laser or another similar power source.[1] History[edit]

3D Printing: one step closer to a Star Trek future? [Infographic] April 20, 2014 Bestcomputerscienceschools.net has published a nice infographic titled "3D Printing: One Step Closer To A Star Trek Future" to help illustrate the power of 3D printing. "On the original Star Trek TV series from the 1960s, they had their fictional replicator technology that materialized food, drink and non-edible objects. ... 3D printing is turning fiction into fact. There's even a 3D printer by MakerBot Industries called the Replicator.

What is a STL File? Simply explained, a stl file is a format used by Stereolithography software to generate information needed to produce 3D models on Stereolithography machines.In fact, the extension "stl" is said to be derived from the word "Stereolithography." A slightly more specific definition of a stl file is a triangular representation of a 3D object. The surface of an object is broken into a logical series of triangles (see illustration at right). Formlabs Form 1 Teardown I got a Form 1 3D printer! It’s the first 3D printer I’ve purchased (technically, I “backed” it). I managed to acquire a pre-release beta unit, as I’m affiliated with Neoteny Labs, one of Formlabs’ investors. What’s the first thing I do with any shiny new gadget? That’s right, I take it apart!

Legacy Filament Extruder soon on Kickstarter, turning old plastic into 3D printer ‘ink’ April 21, 2014 Liz Havlin, a Seattle-based entrepreneur, is working on an Open Source project that turns recycled plastic into 3D printer ink. "The idea is that we can use the garbage which is choking our oceans, beaches and wildlife to create income and foster innovation in impoverished communities around the world." Havlin wrote to us. The extruder she is working on, called the Legacy, is designed by Seattle inventor Hugh Lyman who had won a contest by building the device that turned plastic pellets into 3D printing filament.

G-code G-code is the common name for the most widely used numerical control (NC) programming language, which has many implementations. Used mainly in automation, it is part of computer-aided engineering. G-code is sometimes called G programming language. Implementations[edit]

Curiosity 120$ eWaste Educational 3D Printer - All UPDATE: Our first crowd funding campaign is live on SparkRaise.com! The aim of our campaign is to donate 3D printer kits to needy schools, institutions and other groups around the world who then arrange workshops for children 8-12 years old who otherwise could not afford a 3D printer! Please help us to achieve this worthy and ambitious goal! Just 99USD is enough to spark the curiosity of a child and give him or her the chance of becoming tomorrows Innovator!
