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.
In 2022, engineers reported the development of swarms of autonomous 3D-printing drones for additive manufacturing and repair. [53] [54] In November 2022, researchers at the University of Maine Advanced Structures and Composites Center completed a 600 square feet (56 m 2) home composed of modular sections printed from wood byproducts.

This is a category of templates that generate timelines. A few of them are a specific timeline used in one article context. Others are parameterizable templates, used to generate a particular type of timeline visualization, in multiple contexts.
CAD post-processors will approximate the application vendors' internal CAD geometric forms (e.g., B-splines) with a simplified mathematical form, which in turn is expressed in a specified data format which is a common feature in additive manufacturing: STL file format, a de facto standard for transferring solid geometric models to SFF machines.
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing, while subtractive manufacturing may also be referred to as machining, [1] and many other technologies can be used to ...
All three templates are required. One or more occurrences of {{timeline-item}} may be included; each MUST use {}. See {} for date formatting options. Add {{UF-timeline}} to the External links section of the page, for links to time-line generating software.
[[Category:Automotive company - North America timeline templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Automotive company - North America timeline templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.
