2. Electron-beam additive manufacturing - Wikipedia

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

   Parts are manufactured by melting metal powder, layer by layer, with an electron beam in a high vacuum. This powder bed method produces fully dense metal parts directly from metal powder with characteristics of the target material. The EBM machine reads data from a 3D CAD model and lays down successive layers of powdered material.

3. Material extrusion-based additive manufacturing - Wikipedia

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

   Printing: The process begins with printing the part using a filament containing metal powder bound in plastic. This filament, similar to that used in conventional FFF printers, is infused with metal. The printer deposits the metal-infused filament layer by layer, building up the shape of the part. These printed parts are referred to as "green ...

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

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

   Powder bed and inkjet 3D printers typically range in price from $50,000 to $2,000,000 [citation needed]. However, there is a hobbyist DIY kit selling from $800 to convert a consumer FDM printer to powder/inkjet printer.

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. Titanium powder - Wikipedia

   en.wikipedia.org/wiki/Titanium_powder

   In the direct powder rolling (DPR) process BE powder is used to produce sheet and plate and composite multilayered sheet and plates. Sheets between 1.27 and 2.54 mm and 50 to 99+% dense of single layer CP titanium, Ti Grade 5, TiAl (Ti-48Al-2Cr-2Nb) and composite Ti/Grade 5/Ti and Grade 5/TiAl/Grade 5 have been produced by DPR and sintering.

8. Multi-material 3D printing - Wikipedia

   en.wikipedia.org/wiki/Multi-material_3D_printing

   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.

9. Health and safety hazards of 3D printing - Wikipedia

   en.wikipedia.org/wiki/Health_and_safety_hazards...

   Research on the health and safety hazards of 3D printing is new and in development due to the recent proliferation of 3D printing devices. In 2017, the European Agency for Safety and Health at Work has published a discussion paper on the processes and materials involved in 3D printing, potential implications of this technology for occupational safety and health and avenues for controlling ...
