  2. 3D metal moulding - Wikipedia

    en.wikipedia.org/wiki/3D_Metal_Moulding

    3D metal printing builds components by delivering the powdered metal and binder in alternative layers through a nozzle controlled by a computer system, working to a CAD drawing. The initial process does not achieve the required strength so parts must go through a secondary process which involves fusing another type of metal into the shape.

  3. 3D printing processes - Wikipedia

    en.wikipedia.org/wiki/3D_printing_processes

    As the costs of 3D printers have come down, they are becoming more appealing financially to use for self-manufacturing of personal products. [97] In addition, 3D printing products at home may reduce the environmental impacts of manufacturing by reducing material use and distribution impacts. [98]

  4. Material extrusion-based additive manufacturing - Wikipedia

    en.wikipedia.org/wiki/Material_extrusion-based...

    Material extrusion-based additive manufacturing (EAM) represents one of the seven categories of 3D printing processes, defined by the ISO international standard 17296-2. While it is mostly used for plastics, under the name of FDM or FFF , it can also be used for metals and ceramics.

  5. Multi-material 3D printing - Wikipedia

    en.wikipedia.org/wiki/Multi-material_3D_printing

    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 .

  6. 3D printing - Wikipedia

    en.wikipedia.org/wiki/3D_printing

    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.

  7. Selective laser melting - Wikipedia

    en.wikipedia.org/wiki/Selective_laser_melting

    The process starts by slicing the 3D CAD file data into layers, usually from 20 to 100 micrometers thick, creating a 2D cross-section of each layer; this file format is the industry standard .stl file used on most layer-based 3D printing or stereolithography technologies. This file is then loaded into a file preparation software package that ...

  8. Powder bed and inkjet head 3D printing - Wikipedia

    en.wikipedia.org/wiki/Powder_bed_and_inkjet_head...

    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 ...

  9. Electron-beam additive manufacturing - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_additive...

    Electron-beam additive manufacturing, or electron-beam melting (EBM) is a type of additive manufacturing, or 3D printing, for metal parts. The raw material (metal powder or wire) is placed under a vacuum and fused together from heating by an electron beam. This technique is distinct from selective laser sintering as the raw material fuses have ...
