What we’ll be discussing The origins of 3D printing How far has 3D printing come Where do we see 3D printing headed 2

What is 3D printing? 3D Printing is a process whereby physical, three- dimensional objects are created by a machine, known as a 3D printer, using designs created in CAD 3

Conception First developed by Charles Hull in 1984 He named the technique Stereolithography It was patented in 1986 and available to the general public in by

Growth & Development There are six unique technologies predominantly used in 3D printing. 1. Stereolithography (SL) 2. Fused Deposition Modeling (FDM) 3. Selective Laser Sintering (SLS) 4. 3 Dimensional Printing (3DP) 5. Polyjet 6. Polyjet Matrix 5

Why 3D Printing? Faster turnaround time 8

Why 3D Printing? It saves on manufacturing costs 9

Why 3D Printing? Entry costs into 3D printing continue to go down 10

OK, what’s the catch? CAD models need to be airtight 11

$ Pricing $ About $15,ooo for commercial models Below $1,500 for desktop models (hobbyists) 12

Printing 3D printers? 13

Now what? You wouldn’t download a car. Or would you?

Summary 3D Printing is a process whereby physical, three- dimensional objects are created by a machine, known as a 3D printer, using designs created in CAD First developed by Charles Hull in 1984 There are six unique technologies predominantly used in 3D printing. Entry level desktop printers start at under $1,500 Downloadable 3D objects are known as Physibles 15
