Additive friction stir deposition (AFSD) is a solid-state metal additive manufacturing process that uses a rotating tool to deposit feedstock material onto a substrate. [28] AFSD offers a number of advantages over other metal additive manufacturing processes, including high material utilization, low energy consumption, and the ability to print ...
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.
After several years of trial-and-error, Deckard's machine was capable of manufacturing real parts. He licensed the technology from UT Austin and co-founded Desk Top Manufacturing (DTM) Corp. in 1987. [4] DTM Corp. specialized in rapid prototyping and manufacturing systems for manufacturers and service bureaus.
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 ...
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.

Cold spray additive manufacturing (CSAM) (also called cold spray 3D printing) is a particular application of cold spraying, able to fabricate freestanding parts or to build features on existing components. During the process, fine powder particles are accelerated in a high-velocity compressed gas stream, and upon the impact on a substrate or ...
Stratasys, Ltd. is an American-Israeli manufacturer of 3D printers, software, and materials for polymer additive manufacturing as well as 3D-printed parts on-demand. [4] [5] The company is incorporated in Israel. [6]
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.
