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 be...

3D printing or additive manufacturing is a process of making three dimensional objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of …

Jan 25, 2025 · 3D printing, in manufacturing, any of several processes for fabricating three-dimensional objects by layering two-dimensional cross sections sequentially, one on top of another.

Aug 28, 2024 · Learn about the 7 main types and more than 20 subtypes of 3D printer technology, including FDM, SLS, MJF, SLA, SLM, and many more methods of additive manufacturing.

3D printing uses computer-aided design to create three-dimensional objects through a layering method. Sometimes referred to as additive manufacturing, 3D printing involves layering materials, like plastics, composites or bio-materials to create objects that range in …

Sep 20, 2023 · 3D printing is an additive manufacturing method that creates a physical object from a digital model file. The technology works by adding layer upon layer of material to build up a complete object. The 3D printing process was invented in the 1980s and was originally known as ‘rapid prototyping’.

Nov 20, 2024 · At its core, 3D printing, or additive manufacturing, creates three-dimensional objects layer by layer from a digital design. Unlike traditional manufacturing methods that involve cutting, drilling, or molding material, 3D printing only adds material where needed, resulting in less waste and increased efficiency.

3D printing is additive manufacturing that creates three-dimensional physical objects by layering material, typically plastic, metal, or resin, based on a digital model. Slicing software slices the computer-aided design (CAD) into thousands of horizontal layers and then prints each successively to create the final product.

Jun 24, 2024 · 3D printing consists of a diverse array of methods, each with strengths and applications. This section delves into the various types of 3D printing, unraveling their complexities and showcasing their unique capabilities. Stereolithography, commonly known as SLA, is a pioneering 3D printing technique.

Other 3D printing techniques include stereolithography, sheet lamination, material extrusion, directed energy deposition and various material jetting processes. Dawn of a new technology NSF began supporting the precursors of 3D printing in the 1970s by funding research on computer-aided design and numerical control machining — the automated ...
