3D Printing

  • Process of making a 3D solid object
  • From a digital model
  • Additive
  • It's been around since the 80's, but not popular till 2010
  • 2.2B, up 29% each year

Example 3d printer

What is it used for?

  • Prototyping
  • Distributed manufaturing
  • Construction
  • Automotive/aerospace industries
  • Fashion
  • Food
  • And many other fields

Technology

Additive

  • Joining
  • Forgin
  • Riveting
  • Screwing
  • Welding


Substractive

  • Filing
  • Milling
  • Drilling
  • Grinding

The process

It starts with 3D models

Slicing

Transforming a 3D model to a printable file

Generate Gcode

  • Each 3D printer has their own way of printing
  • Gcode is the unifying language to print on any device
  • Gcode is interpreted by the 3D printer's firmware


Example...

Building

  • Once the machine is told to build
  • a computer gives serial commands to the printer
  • (This is the Gcode)
  • It executes these commands blindly

Finished product

  • After 10 minutes - 4 hours
  • You come out with a 3D printed product

Some other things

  • ABS/PLA
  • Which 3D Printer should you buy?
  • 3D printed guns
  • 3D printed prosthetics
  • 3D printers in space

3D printers

RepRap

  • Open sourced self-replicating 3d printer
  • Changing the idea of building as we know it
  • Used by thousands of people in the maker community

Thingiverse

  • The Github for sharing 3D files
  • A platform for open source hardware designs
  • Owned by Makerbot

Shapeways

  • Best place for getting high-quality prints
  • Print in plastic, steel, gold/silver, sandstone
  • Just upload a 3d file and see the 3d version on your doorstep the next week.

DEMO!
