Welcome to 3D Printing! 🎉

3D printing, also known as additive manufacturing, builds physical objects layer by layer from digital files.

Info
3D printing is revolutionizing manufacturing, from prototyping to producing custom parts on demand.

How 3D Printing Works

  1. 1Design - Create a 3D model in software
  2. 2Slice - Convert the model into layers
  3. 3Print - The printer builds layer by layer
  4. 4Finish - Remove supports and clean up

Common Technologies

FDM (Fused Deposition Modeling)

  • Melts plastic filament through a hot nozzle
  • Most affordable and common
  • Great for functional parts
Tip
FDM printers are perfect for beginners - they're affordable and the materials (PLA filament) are easy to work with!

SLA/Resin (Stereolithography)

  • Uses UV light to cure liquid resin
  • Higher detail and smooth surfaces
  • Great for miniatures and jewelry
Warning
Resin printing requires proper ventilation and safety equipment. The liquid resin can be toxic before it's cured.

What You'll Learn

  • Designing for FDM printing constraints
  • Understanding scale and tolerances
  • Creating support-free designs
  • Exporting print-ready STL files
Important
By the end of this course, you'll be able to create your own 3D printable designs from scratch!
