Week Overview

This week, we are characterizing the 3D printers and creating 3D prints on our own.

Neil’s lecture Notes

• The printhead need to be at the right distance.
• Bridging:
  • If the print is anchored at 2 points, then the bridge between the 2 anchors could span quiet a distance.
• Angle:
  • 3D printer layers can build on itself to create 20 degree and 30 degree arcs.
• Fumes:
  • ABS filament typically produce harmful fumes.
  • PLA doesn’t.
• Hangover:
  • The more it hangs over, the worse it gets.
• Friction joint:
  • Use of abrasives to join joints.
• Nano printing:
  • Use of 2 photons to print extremely tiny pieces.
• Extrusions allow a 3D printer to print things larger than the machine itself.
