Introduction3D printing is a form of additive manufacturing technologyIt is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object.The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.

HistoryThe technology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986. While Stereo lithography systems had become popular by the end of 1980s, other similar technologies such as Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were introduced.

TechnologyHow it worksThe different types of 3D printers each employ a different technology that processes different materials in different ways. Others include sanding, lacquer, paint or other types of traditional finishing touches, which all typically need to be done by hand and require skill and/or time and patience.

MaterialsThe materials available for 3D printing have come a long way since the early days of the technology. There is now a wide variety of different material types, that are supplied in different states.PlasticsMetalsCeramicsPaperBio MaterialsFoodOther
