Hello everyone! …

Hello everyone!

I'm running an introductory session on 3D printing this Wednesday at /usr/lib if anyone's interested in coming to check it out.
I'll be covering:
- What you can make
- What materials you can use
- Basic cost expectations of using online services such as Shapeways, Ponoko
- What software is available to use
- A quick demo on how easy it is to start making basic geometry in Blender.
- A lengthy Q&A at the end can be opened up, I can hang around for quite a while afterwards

    • 2. SO, WHAT IS 3D PRINTING?
    • 3. WIKIPEDIA SEZ...• “3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material.” - Wikipedia
    • 4. OR...• “Its like bringing an inkjet printer into the third dimension!” - Susan Hinton
    • 5. A QUICK DEMO
    • 6. WHAT SORT OF MATERIALS ARE WE TALKING?
    • 7. MATERIALS AVAILABLE• Virtually any colour plastic • Ceramic• Stainless steel • Allumide• Titanium• Wax casts (for silver parts)• Full colour sandstone• Glass
    • 8. WHAT CAN I MAKE?
    • 9. JEWELLERY
    • 10. CUSTOM TOYS
    • 11. SPARE PARTS
    • 12. IMPLANTS/PROSTHETICS
    • 13. MUGS
    • 14. WHY IS 3D PRINTING BETTER?
    • 15. 3D PRINTING:• Adds rather than subtracts material to create the object• Any waste is easily reused in next print run• Print an object with moving parts all in one piece• Fast way to test a design• IT’S FRAKKING COOL!
    • 16. SO, I WANT TO PRINT SOMETHING. Where do I start?
    • 17. YOU WILL NEED...•a computer• 3D modelling software eg. CAD, Blender, Z-Brush•A 3D printer or THE INTERNET• Some pocket money• Enthusiasm for learning by trial and error
    • 18. WHAT’S THE PROCESS?
    • 19. STEP 1:Create your cool idea in 3D modelling software
    • 20. STEP 2:Upload the model file to a 3D printing service online
    • 21. STEP 3:Choose your material and place your order
    • 22. STEP 4:Wait for it to arrive!
    • 23. THE PROCESS:• 1) Create some cool stuff in 3D modelling software• 2) Upload the model file to a 3D printing service online• 3) Choose your material and order• 4) Wait for it to arrive!• 5) ???• 6) Profit
    • 24. OKAY, WHO CAN PRINT MY STUFF FOR ME?
    • 25. 3D PRINTING SERVICES• Shapeways (my favourite) http://shapeways.com• iMaterialise http://i.materialise.com• Ponoko http://ponoko.com
    • 26. WAIT A SECOND, WHAT’S ALL THIS GONNA COST ME?
    • 27. EXAMPLE COSTS• Plastic starts at $1.40 per cm cubed• Stainless steel starts at $8.00 per cm cubed• Glass starts at $6.00 per cm cubed• most materials have a modest handling fee
    • 28. AND WHERE DO I FIND FREESOFTWARE TO GET STARTED?
    • 29. FREE 3D MODELLING WAREZ• Blender (I use this) http://blender.org• AutoDesk 123D http://www.123dapp.com/• TinkerCAD http://tinkercad.com/ (browser based)• Google SketchUp http://sketchup.google.com/
    • 30. BLENDER ADVENTURES!
    • 31. WHAT DO I NEED TO KNOW?• It’s free!• Blender can be a little tricky to learn at first• You totally need a mouse (a trackpad will make you suicidal)• Blender supports svg imports, can export to stl format• There is good documentation and youtube tutes online
    • 32. MOST COMMON TOOLS YOU WILL USE IN BLENDER• Scale - sizing of objects and polygons• Extrude - give that mofo some depth, yo• Boolean modifier - drill holes and scoop out areas• Loop cut and subdivide - make some new detail to work with
    • 33. WATCH AND LEARN, GRASSHOPPER
    • 34. NOW, GO PRINT SOME EPICNESS!
    • 35. QUESTIONS..?
