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.
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.
Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
3D printing is used to manufacture moulds for making jewelry, and even the jewelry itself. [102] 3D printing is becoming popular in the customisable gifts industry, with products such as personalized models of art and dolls, [103] in many shapes: in metal or plastic, or as consumable art, such as 3D printed chocolate. [104]
The 3D model can be physically created using 3D printing devices that form 2D layers of the model with three-dimensional material, one layer at a time. Without a 3D model, a 3D print is not possible. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling ...
Shapeways, Inc. is a global, 3D printing marketplace and service, private company. Users design and upload 3D printable files, and Shapeways prints the objects for them or others. [2] [3] 3D printing resources are available for university students, faculty, and educators with an .EDU email [4]
Pinshape was founded in 2013 by Lucas Matheson (CEO), Nick Schwinghamer (COO), and Andre Yanes (CTO). [5] The site is a marketplace that showcases the digital work of 3D designers from all over the world. 3D print designers set their own prices for their design files, and also choose which license to offer their work under (Creative Commons or other).
A demonstration of a sample print, printed by the D-Shape 3D printer. D-Shape is a large 3-dimensional printer that uses a binder-jetting, a layer-by-layer printing process to bind sand with inorganic seawater [1] and magnesium-based binder [2] to create stone-like objects.
