Multi-material 3D printing is the additive manufacturing procedure of using multiple materials at the same time to fabricate an object. Similar to single material additive manufacturing it can be realised through methods such as FFF , SLA and Inkjet (material jetting) 3D printing .
3D printing filament in different colours with models created using the filament. 3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter ...
[86] [87] The most popular 3D printer in the world is the Prusa i3, a RepRap printer. [88] [89] Because of the FOSH aims of RepRap, many related projects have used their design for inspiration, creating an ecosystem of related or derivative 3D printers, most of which are also open-source designs. The availability of these open-source designs ...
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.
3D printing, and open source 3D printers in particular, are the latest technology making inroads into the classroom. [158] [159] [160] 3D printing allows students to create prototypes of items without the use of expensive tooling required in subtractive methods. Students design and produce actual models they can hold.
Regardless of the system used for printing (gantry crane or robotic arm), the coordination between the nozzle travel speed and the material flow rate is crucial to the outcome of the printed filament. [95] In some cases, multiple 3D printing robotic arms can be programmed to run simultaneously resulting in decreased construction time. [96]
