1. Introduction to 3D Printing
Jim Young – 1/2017

2. Definition
The making of parts and products using a computer-driven, additive process, one layer at a time. 3D printing builds parts out of plastic, metal and other materials directly from CAD drawings that have been cross sectioned into thousands of layers. Sizes of printed objects run the gamut from approximately 16 to 4,000 cubic inches.

4. How did we get to here?
CAD (Computer Aided Design): Computer aided design processes have been around for several years. It started with the dot matrix printer, then a plotter, laser printers, inkjet printers and finally we have reached the era of the 3D printer.
Being able to actually form an object from that process is a whole other ballgame.

5. CNC Machining (Subtractive)

7. CNC PROS and CONS Pros- (Subtractive Method)
It was the first/best method of both prototyping products and making product molds for pouring.
Cons –
Lost of waste product.
Slow, slow, slow.
Design Limited by cutter design.

8. 3D Printing

9. What’s so important about 3d printing?
Viewed by many as the beginning of the third industrial revolution.
Brings back the inventor mindset.
Anyone can do it.

10. 3D PRINTER PROS and CONS Pros - (Additive Method) Little or no waste.
Intricate designs. (If you can draw it you can 3D print it.
Fast compared to CNC machining.
A great number of colors and materials.
Cons –
Not good for mold making.
