3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model.
3D打印（英語： 3D printing ），又称立體打印、增材制造（英語： Additive Manufacturing，AM ）、積層製造，可指任何打印三维物体的过程。 3D打印主要是一个不断添加的过程，在计算机控制下层叠原材料。
3D printing processes. Computer-Aided Design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
3D printing is a way of creating three dimensional (3D) solid objects. [1] 3D printing is done by building up the object layer by layer. [2] Usually, 3D printers use plastic, because it is easier to use and cheaper. Some 3D printers can 3D print with other materials, like metals and ceramics, but they cost too much money for most people.
Applications of 3D printing. In recent years, 3D printing has developed significantly and can now perform crucial roles in many applications, with the most common applications being manufacturing, medicine, architecture, custom art and design, and can vary from fully functional to purely aesthetic applications. 3D printed chocolate.
Stereolithography (SLA or SL; also known as vat photopolymerisation, 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 ...
Fused filament fabrication ( FFF ), also known as fused deposition modeling (with the trademarked acronym FDM ), or filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. [1] Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the ...
Feb 20, 2024 · Key Takeaways. 3D printing origins: The first 3D printing technology, Stereolithography (SLA), was invented by Chuck Hull in 1984. He founded 3D Systems and released the first 3D printer, the SLA-1, in 1987.
The Prusa i3 is a family of fused deposition modeling 3D printers, manufactured by Czech company Prusa Research under the trademarked name Original Prusa i3. Part of the RepRap project, Prusa i3 printers were called the most used 3D printer in the world in 2016.
Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.
