3D Printing is cool, but you can’t doanything unless you have models…
How you get models????
CAD• Sketchup (great for beginners) – http://www.sketchup.com/• Autodesk (decent amount of functionality) – http://students.autodesk.com/?nd=download_center• Solidworks (most ME students use this) – http://store.solidworks.com/studentstore/default.php• Blender (great for animations) – http://www.blender.org/download/get-blender/• OpenScad (CAD for programmers/great for making “apps”) – http://www.openscad.org/
Get models from www.thingiverse.com*Not everything is necessarily 3D printable
Save as .stl• Save your model as a .stl file – Be careful what units you save in – Be careful what resolution you save in • Not too high or too low• Have a student version of Solidworks? – Save as .stl with eDrawings – http://www.edrawingsviewer.com/ed/download.h tm
Now for some vocabulary…
3D Printing Vocabulary *pertains mainly to FDM• Layers• Walls• Fill• Supports• Build Platform• Filament• Extruders• Build Envelope
Vocabulary: Layers• Layers are 0.4 mm wide and 0.1 to 0.27 mm thick• Resolution means usually means how thin the layers are
Vocabulary: WallsMinimum wall thickness is 0.4 mm (based on layer width)
Vocabulary: Fill10% vs. 50% vs. 100%
Vocabulary: Build Platform
Vocabulary: Extruder HeadSquirts out filament onto build platform at 210-230 degrees celsius
Vocabulary: Build Envelope/Volume
General Strategies for FDM• Not all models are 3D printable• Good resources for guidelines: – http://www.dreams.me.vt.edu/dreamvendor/TipsA ndTricks/index.htmldreambox – http://3dreambox.com/reference.html – Feel free to email us too at firstname.lastname@example.org and we will be happy to help!
Cool 3D Printing Projects @ Cal
There are endless possibilities with 3D printing!
• Eric Sweet, Sophomore ME, CAD (Solidworks) enthusiast, satisfied Dreambox customer!• Some of my designs and prints:The Wall (from Game of Thrones) Our CampanileCoit tower, GGB, TransAmerica Pyramid, Big Ben, etc. coming soon!
Future Dreambox 3D Printing Projects• Come CAD with Dreambox!• Want to hang out here with Dreambox and attend some informal CADing and printing infosessions? – Meet weekly or biweekly HERE at Dreambox HQ – Ask questions, CAD together, print your designs, and learn from and help teach your fellow 3D modeling hobbyists your CAD skills!
3D Modeling Project• I’d like to lead a CAD project this semester• Idea: 3D model (relatively) to scale all the major buildings on Campus– 3D Print designs and build a 3D “map” of UC Berkeley!• Fun semester-long goal, great opportunity to learn, improve upon, and share your 3D modeling skills.• If interested, come talk to me in a few minutes and we’ll talk more about the project!
Get creative, experiment with new designs, and challenge the3D printer…… The outcomes may surprise you!
3D Printing @ Cal• Facebook group• All of these slides will be posted there• You should all join! – http://on.fb.me/125Lf1D – Posted on the Facebook event page – How we will coordinate CAD/3D printing projects
