WHAT IS 3D PRINTING? - TECHNOLOGY DEFINITION AND TYPES
3D printing, also known as additive manufacturing, is a method of creating a three dimensional object layer-by-layer using a computer created design.
WHAT IS 3D PRINTING?
A variety of 3D printing materials includes thermoplastics such as acrylonitrile butadiene styrene (ABS), metals, resins and ceramics.
Building on Ralf Baker's work in the 1920s for making decorative articles, Hideo Kodama's early work in laser cured resin rapid proto-typing was completed in 1981.
History of 3D Printing
There are three broad types of 3D printing technology;
3D Printing Technologies
– Binder Jetting
– Direct Energy Deposition
– Material Extrusion
– Material Jetting
– Powder Bed Fusion
– Sheet Lamination
– VAT Polymerization
3D Printing Processes
3D printing can take anything from a few minutes to several hours or days - speed, resolution and the volume of material are all important factors here.
