What is Additive Manufacturing and its uses?

3D printing, Additive Manufacturing (AM), or Rapid Prototyping (RP) is the process of fabricating objects by building materials by adding layers with the help of a 3D modeling software such as AutoCAD. This differs from traditional manufacturing techniques such as casting, molding, or subtracting materials from an existing starting material.

What materials are used in 3D printing?

Plastics or resins, metals and alloys such as titanium Ti-6Al-4V alloy and sterling silver, and ceramic materials such as oxides and nitrides. These materials are typically in powdered form, although alternatives like inks may also be used.

Which industries use 3D printing?

Industries that currently used 3D printing include aerospace and aircraft, automotive, biomedical devices, dental, consumer electronics, and defense, pharmaceutical manufacturing, photovoltaics, space, jewelry, and consumer goods manufacturing.

What are the advantages of 3D printing?

3D manufacturing is cost and time efficient; allows for the fabrication of customizable, complex designs that would be impossible to produce via casting or machining, in addition to requiring no tooling. Because the volume of material used (and thus waste material generated) is much lower than in traditional subtractive manufacturing techniques, 3D printing is becoming increasingly important green technology.

What are the different 3D printing techniques?

3D printing techniques include Direct metal laser sintering (DMLS), selective laser sintering (SLS), Powder bed technologies such as Selective Laser Melting (SLM), Electron Beam Melting (EBM), and Precision inkjet printing; Blown powder technologies such as Laser Metal Deposition or Laser cladding. Methods can include various types of sintering and extrustion.

Is it possible to 3D print graphene foam?

Yes! 3D graphene foam is typically produced via chemical vapor deposition, but researchers have been able to 3D print low-density graphene foam by using a mixture of nickel and sucrose and a CO2 laser. Read more about the experiment at http://pubs.acs.org/doi/abs/10.1021/acsnano.7b01987.
