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.
Alumide is a material used in 3D printing consisting of nylon filled with aluminium dust, its name being a combination of the words aluminium and polyamide.Models are printed by sintering a tray of powder, layer by layer. [1]
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 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.
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
RepRap (a contraction of replicating rapid prototyper) is a project to develop low-cost 3D printers that can print most of their own components. As open designs , all of the designs produced by the project are released under a free software license , the GNU General Public License .
3D printing is used to manufacture moulds for making jewelry, and even the jewelry itself. [102] 3D printing is becoming popular in the customisable gifts industry, with products such as personalized models of art and dolls, [103] in many shapes: in metal or plastic, or as consumable art, such as 3D printed chocolate.

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.
