3D Printing Guide Cheat Sheet

What is 3D printing?

3D printing is “additive manufacturing”: a manufacturing method wherein material is selectively added.

What are people 3D printing?

  • Prototypes
  • Gadgets
  • Scale Models
  • Props
  • Medical Devices, Prosthetics, and Surgical Guides

What industries use 3D printing?

  • Industrial/ Product Designers
  • Architects
  • Jewelry Designers
  • Engineers
  • Toy Designers
  • Artists and Animators
  • Research Scientists and Medial Professionals
  • Fashion Designers
  • Hobbyists and Tinkerers

History of 3D printing

3D printing was invented in 1986 by Chuck Hull at 3D Systems. ¬†Expiring patents, new low cost models, and an enthusiastic community of early adopters led to a significant growth in 3d printing’s popularity around 2009.

3D Printing Advantages

  • Complex geometry
  • Lighter, stronger, parts
  • Faster design cycle iteration
  • “Long tail” customized products
  • On demand manufacturing
  • Reduced waste

3D Printing Disadvantages

  • Speed
  • Price/ economies of scale
  • Limited material properties
  • Surface finish not smooth
  • Limited size constraints
  • Unreliable hardware

3D Printing Files

File Types

  • .STL (most common)
  • .OBJ (sometimes for color files)
  • .VRML (color files)

Technical Specs

  • “water tight” model with surfaces pointed in the correct direction
  • repair 3d models using NetFabb
