Some important 3D printer metrics include: Print technology: 3D printing processes encompasses a variety of methods which each have their own unique challenges. Length of production run and support: 3D printers often require adjustments and parts replacement. A long production run often means that spare parts are also available.
The Prusa i3 is a family of fused deposition modeling 3D printers, manufactured by Czech company Prusa Research under the trademarked name Original Prusa i3.Part of the RepRap project, Prusa i3 printers were called the most used 3D printer in the world in 2016. [1]
Form 1 3D printers began shipping to backers in May 2013 after months of delayed production. [15] [16] The Form 1 used a 3D printing process known as stereolithography, wherein liquid resin is cured, or hardened, into a solid material by the application of laser light. Although previously available in larger, more expensive machines, the Form 1 ...
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.
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.
In 2021, Stratasys acquired the outstanding shares of Xaar 3D, which Stratasys purchased from Xaar. Xaar 3D provides 3D printers using SAF Selective Absorption Fusion technology, a type of powder bed fusion. This technology is designed to 3D print polymer production parts at volume. The first printer used the technology is called the H350. [34]
3D printing technology has a limited potential to vary material properties in a single build, but is generally limited by the use of a common core material. In the original Z Corporation systems, cross-sections are typically printed with solid outlines (forming a solid shell) and a lower-density interior pattern to speed printing and ensure ...
An example of how 3D printing can be included in the design process is automotive design. [19] There, it is necessary to quickly test and verify a prototype to get the design approved for production. The reduced post-processing steps induced by the multi-material 3D printing technology result in a shorter fabrication time.
