Learn the basics of 3D design and printing.

2. 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

3. 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.

4. • 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:

5. 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.

6. Huh?

7. 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
http://reprap.org/wiki/PLA for more information.

9. 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.

12. 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.

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