FDM (fused deposition modeling) printing is one of the most popular types of 3D printing, [1] it is used throughout different engineering industries (medical, robotics, automotive) [1] and also has a great number of individual users that enjoy 3D-printing as a hobby. [2] FDM printing is so popular because it can produce near finished models of ...
In 2005, a system was development at the Drexel University, based on material extrusion, consisting of a mini-extruder with a single screw mounted on a high-precision positioning system, fed with bulk material in granulated form (pellets); [6] In 2015, a 3d printing machine was developed at Politecnico di Milano for MIM metals and CIM ceramics ...
A desktop FFF printer made by Stratasys. Fused deposition modeling was developed by S. Scott Crump, co-founder of Stratasys, in 1988. [6] [7] With the 2009 expiration of the patent on this technology, [8] people could use this type of printing without paying Stratasys for the right to do so, opening up commercial, DIY, and open-source 3D printer applications.
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 RepRap Morgan is an open-source fused deposition modeling 3D printer.The Morgan is part of the RepRap project and has an unusual SCARA arm design. [1] The first Morgan printer was designed by Quentin Harley, a South African engineer (working for Siemens at the time) at the House4Hack Makerspace in Centurion. [2]
Typically desktop 3D printers can make small plastic 3D objects. They use a roll of thin plastic filament, melting the plastic and then depositing it precisely to cool and harden. They normally build 3D objects from bottom to top in a series of many very thin plastic horizontal layers. This process often happens over the course of several hours.
