Introduction
The first Stereolithographic Apparatus (SLA) is made by 3D Systems
Charles “Chuck” Hull invented the first form of 3D printing – Stereolithography
3D printers sold per year. Sales of consumer-grade machines (less than $5,000) begins in 2007 and outpaces sales of industrial-grade machines in 2011.

Fused Deposition Modeling (FDM)
Material: soft plastic, living cells or even raw cookie doughPluses: ideal for home and office useMinuses: use only soft materials
Polyjet (Material Jetting)
Material: photopolymerPluses: fast and preciseMinuses: photopolymer is expensive and fragile
Laser Engineered Net Shaping (LENS)
Material: usually metal materialsPluses: can use hard materialsMinuses: not for home use
