Origins of 3 D Printing • 1980 s: “rapid prototyping” machines; “stereolithography apparatus” (SLA) • 1990 s: ballistic particle manufacturing (BPM); laminated object manufacturing (LOM); solid ground curing (SGC); three dimensional printing (3 DP) • Most systems were for industrial use up until 2007, when consumer models started to appear

How Does 3 DP Work? • additive manufacturing vs. subtractive manufacturing • printing material: plastic, metal (gold, silver, titanium, etc. ), wax, ceramics • research is ongoing into printing tissue, organs subtractive additive

Why is 3 D Printing Useful? • rapid prototyping • can print things that would be too intricate to create any other way • can create tools that no one else has thought of, solve new types of problems
