Introducing 3D Design and Printing

  1. 1. Agenda - Learn what 3D printing is and how it works - Get a snapshot of some of the best 3D printers on the market - Discovery a variety of 3D design applications - Study trends in digital scanning and other emerging 3D design/printing technologies - Understand how to implement and maintain a 3D printer in your library or makerspace
  2. 2. What is 3D printing? First off, 3D printing is not new. Chuck Hull invented stereolithography (i.e., solid imaging) in the mid-1980s. 3D printing is also known as additive manufacturing , which is a process of making, layer by layer, three dimensional objects from a digital file. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. Source:
  3. 3. • Vat Photopolymerisation • Material Jetting • Binder Jetting • Material Extrusion – The iLab’s Monolith printer uses Fused Deposition Modeling (FDM) technology • Powder Bed Fusion • Sheet Lamination • Directed Energy Deposition Seven processes are:
  4. 4. 3D Printing File Types .STL – STereoLithography or Standard Tessellation Language .OBJ – Object files define the geometry for objects. Includes textures. .X3D – used for color printing. Also added shaders, geo-location etc. .VRML – used for color printing. Includes 3D geometry etc.
  5. 5. Huh?
  6. 6. 3D Printing Process 1. Design an object via computer aided design (CAD) or animation modeling software. Not design-oriented? Try Shapeways, Sculpteo or Thingiverse. 2. The software will export the object as an .STL file ("stereolithography" or "Standard Tessellation Language"), which will then be built (printed) layer-by-layer (i.e., Additive Manufacturing). 3. Load the .STL file into the printer. (e.g., via Repetier). 4. Slice (i.e., create layers for the object). Note: Repetier integrates Slic3r into the software. 5. 3D printing materials vary. We use PLA (Polylactic acid) filament. Visit for more information. Source:
  7. 7. Download it at Repetier Demonstration
  8. 8. G-code is a language in which people tell computerized machine tools how to make something. G-code can also be used for CNC machines, knitting, tattoos etc. Visit for a large list of other 3D modeling, Slicer, 3D Printer Hosts etc.

  11. 11. What to Expect with 3D Printing • It is a slow process. • It can be very frustrating. • You will learn how to unclog the extruder and do other repairs. • Setup a way to remotely monitor your prints (e.g., use a webcam via RealVNC or Repetier-Server etc.) • Have a web form for print submissions with brief explanation. • Create procedures/policies.

  13. 13. Note: you do not need to use a Raspberry Pi, but you will be cooler if you do. ;-)
