2 1981 : Early additive manufacturing equipment and materials were developed in the 1980s. Dr. Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three- dimensional plastic models with photo-hardening thermoset polymer.

3 1984 : Alain Le Méhauté, Olivier de Witte, and Jean Claude André filed their patent for the stereolithography process. The application was abandoned by the French General Electric Company (now Alcatel-Alsthom) "for lack of business perspective". Three weeks later in 1984, Chuck Hull of 3D Systems Corporation filed his own patent for a stereolithography fabrication system. Hull's contribution was the STL (Stereolithography) file format and the digital slicing and infill strategies common to many processes today. Odysseas Levantis MBCS, CITP, CEng

4 In 1992, Bill Clinton played sax on The Arsenio Hall Show (SLA) — 3D Systems (Charles Hull’s company) created the world’s first stereolithographic apparatus (SLA) machine, which made it possible to fabricate complex parts, layer by layer, in a fraction of the time it would normally take. That same year, startup DTM produced the world’s first selective laser sintering (SLS) machine—which shoots a laser at a powder instead of a liquid. Odysseas Levantis MBCS, CITP, CEng

5 PLA Polylactic Acid, commonly known as PLA, is one of the most popular materials used in desktop 3D printing. Derived from crops such as corn and sugarcane, PLA is renewable and most importantly biodegradable default filament of choice for most extrusion-based 3D printers :  it can be printed at a low temperature temperature  it is easy to print  very inexpensive  creates parts that can be used Odysseas Levantis MBCS, CITP, CEng for a wide variety of applications for a wide variety of applications  most environmentally friendly filaments on the market today filaments on the market today

6 HIPS High Impact Polystyrene, is a dissolvable support material that is commonly used with ABS (Acrylonitrile Butadiene Styrene). When being used as a support material, HIPS can be dissolved in d-Limonene, leaving your print free of any markings caused by support removal. Odysseas Levantis MBCS, CITP, CEng HIPS has many of the same printing properties as ABS prints :  it’s more dimensionally stable  slightly lighter than ABS  a great choice for parts that would end up getting worn out would end up getting worn out  used in applications that can benefit from the lighter weight benefit from the lighter weight

7 Polycarbonate Polycarbonate is known for its strength and durability. It has very high heat and impact resistance making it an ideal choice for tough environments. Odysseas Levantis MBCS, CITP, CEng Wood Filled Wood Filled Wood filaments combine a PLA base material with cork, wood dust, or other derivatives, giving the models a real wooden look and feel. Metal Filled Metal Filled Metal filled filaments are made by mixing a fine metal powder into a base material, providing a unique metallic finish and added weight.
