About 3D Printing

3D printing is a catch all term referring to a range of different additive manufacturing technologies. Essentially it means the construction of an item from a digital 3D file. Typically it is built up in layers, and the most common 3D printing technology is called Fused Filament Fabrication (FFF). There are a number of different technologies, but they tend to fit into one of the following types:

  • Light polymerised based technologies such as Stereolithography (SLA) and Digital Light Processing (DLP)
  • Powder based technologies such as Selective Laser Sintering (SLS)
  • Laminated based 3D printing such as Selective Deposition Lamination (SDL)
  • Extrusion technologies, such as Fused Filament Fabrication (FFF)

Why Use 3D Printing?

Fused Filament Fabrication (FFF)

FFF is the most common 3D printing technology, there are a lot of different manufacturers of the FFF technology 3D printers. Typically these 3D printers use ABS, PLA and a number of other materials.

Nearly all of the 3D printers aimed at the consumer market are likely to be based on FFF technology. This is because of public access to the RepRap project means anyone can create their own 3D printer.

Essentially a filament of a particular material is fed through a tube into a heated extruder, this then melts the material and it is then extruded in small dots, often at layers of around 100 microns or 0.1mm. The 3D printer then builds these up over time, if there are overhangs (for example an archway) then support material has to be used.

FFF is ideal for cheap and quick prototyping of very simple parts.

Stereolithography (SLA)

Stereolithography is ideal for doing small, intricate items. There are many applications of SLA, for example: prototyping, dentistry and jewellery.

SLA works by often using a resin and a light to cure the resin. Rather than building up from the bottom, like in FFF, Stereolithography pulls up out of a bed of resin, with the light curing each layer of resin as it goes.
