Metal and glass may both be used for 3-D printing as well, though they are much more expensive and generally used for works of art. However, the development of WAAM (wire arc additive manufacturing) has reduced the costs of metal 3-D printing. FDM is somewhat restricted in the variation of shapes that may be fabricated.
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.
Mozal is an aluminium smelter joint project in Beluluane Industrial Park, Maputo, Mozambique. [2] The project is a smelting facility that began operations as a producer of aluminium exclusively for export. The smelter is located 20 kilometres (12 mi) west of the city of Maputo in the south of the country.
Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
Screen printing may be adapted to printing on a variety of materials, from paper, cloth, and canvas to rubber, glass, and metal. Artists have used the technique to print on bottles, on slabs of granite, directly onto walls, and to reproduce images on textiles which would distort under pressure from printing presses.

Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image. [ 1 ]
Digital printing is a method of printing from a digital-based image directly to a variety of media. [1] It usually refers to professional printing where small-run jobs from desktop publishing and other digital sources are printed using large-format and/or high-volume laser or inkjet printers.
