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.
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 ...
In computer vision and computer graphics, 3D reconstruction is the process of capturing the shape and appearance of real objects. This process can be accomplished either by active or passive methods. [1] If the model is allowed to change its shape in time, this is referred to as non-rigid or spatio-temporal reconstruction.
The 3D CAD product, now known as SolidWorks, is the central product for the SolidWorks brand. [2] As of 2024, SolidWorks had an estimated 3 million users. [5] [6] SolidWorks provides analyses and simulations, including Finite Element Analysis. This approach can result in faster modeling, new design tools, and enhanced collaboration. [7]
Holography. Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
3D Systems Corporation is an American company based in Rock Hill, South Carolina, that engineers, manufactures, and sells 3D printers, 3D printing materials, 3D printed parts, and application engineering services. The company creates product concept models, precision and functional prototypes, master patterns for tooling, as well as production ...
Building information modeling. Building information modeling (BIM) is a process involving the generation and management of digital representations of the physical and functional characteristics of buildings and other physical assets. BIM is supported by various tools, technologies and contracts. Building information models (BIMs) are computer ...
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane. 3D projections use the primary qualities of an object's basic ...
