7. Design Revisions Happen

8. Fails Happen Photo Credits: http://www.pinterestfail.com

9. 3D Printing Fails Happen

10. Tinkercad – Signing In http://www.tinkercad.com Signing in is straight forward

11. Tinkercad - Workplane Like a piece of graph paper. By Default– Millimeter measurements (Can be changed)

12. Tinkercad – Camera Controls Navigation Buttons (officially called “The Camera”) on the upper left hand corner Right Click allows you to move the “camera” Shift Right Click allows you to pan Mouse Scroll Wheel lets you zoom in and out

13. Tinkercad – Shapes, Letters, Numbers, Etc. Our building blocks. To start click on the “Geometric Shapes” icon

14. Tinkercad - Shapes You can build a lot out of standard shapes

15. Tinkercad - Shapes You can build a lot out of these standard shapes- “Bipedal Mech ” by Mathew Ridge in Tinkercad ! http:// shpws.me/GQX5

16. Tinkercad - Adding Shapes Drag and Drop to Your Workplane

17. Tinkercad - Selecting Shapes Left Click on a Shape to Select It Holding the Shift Key Allows you to Select Multiple Objects You can also draw a box to select multiple objects at once.

18. Tinkercad - Clicking You can think of it as alphabetic order: Left Clicks  Shapes Right Clicks  Workplane Mouse Image by Wasin Waeosri

19. Tinkercad - “Inspector” Additional Properties for the Object Such as Colors and Holes (More Later)

20. Tinkercad - Moving Things on the Workplane Photo Credit: Project Ignite

21. Moving Things – Along the Workplane Along the Workplane (X and Y), just Left Click and Drag and Drop Tip: Be careful to click on the object and not one of the icons. The numbers and arrows show you how far you have moved it.

22. Moving Things – Up and Down To move up and down off the workplace, Left Click on the little arrow icon and drag. As you pull it up, you’ll see a shadow, indicating the object is not resting on the workplane . The numbers to the right of the object tell you exactly how far it is off the workplane

23. Moving Things – Up and Down The practical application is to put objects on top of each other.

24. Moving Things - Nudging You can also use the arrow keys to nudge. How far is each press of the arrow key? It’s defined in the lower right hand corner in the Snap Grid To nudge 10 units at a time, hold down the Shift key and use the arrow keys at the same time. To nudge up and down (off the workplane ), hold down the Control key as you use the arrow keys

25. Tinkercad - Rotating When an object is selected, the three little curved arrow icons (the “Rotation Handles”) allow you to rotate your object.

26. Tinkercad - Rotating A circle appears to help you rotate (The “Protractor”) The Inner Circle rotates at 22.5 degrees steps The Outer Circle rotates at 1 degree steps Holding down S hift rotates at 45 degrees steps

27. Tinkercad - Resizing (Scaling) When you select and object, there are black and white dots (the “Scaling Handles”)

28. Tinkercad - Resizing White Dots scale two sizes (dimensions) at once Black Dots scale one size Hint: You can tell what sides you are resizing by the n umbers

29. Tinkercad - Resizing The White Dot (“handle”) at the top allows you to control the height of your object

30. Tinkercad - Resizing – Proportional If you want to resize everything uniformly (you love your object, you just want it bigger all around), hold down the Shift key. If you want to grow out from the center while resizing, hold down the Alt Key

31. Tinkercad – Copying Items Using the menu option you can do Edit->Copy and Edit->Paste (like in Word) You can also do Ctrl-C and Ctrl-V Holding down the Alt key while you Left Click and Drag will also make a copy of the object. You can select multiple objects at once and copy and paste those too.

32. Tinkercad - Fixing Mistakes Undo/Redo Like Word, Excel or most programs, you have the ability to Undo and Redo steps. Delete Just click on the object and click the Delete button

33. Tinkercad - Holes Any Shape, Letter, Number, etc Can Be Turned Into a Hole Holes allow you to subtract an object from another Click on the Inspector and select Hole

34. Tinkercad - Holes Practical Applications: Actual Holes To Change Shapes Or to Engrave!

35. Tinkercad - Grouping Grouping makes multiple mbjects into one and applies any holes Select your objects and hit Group. You can always Ungroup .

36. Tinkercad – Download for 3D Printing Click on Design -> Download for 3D Printing In most cases, you’ll pick .STL as the format

37. Design Time!

38. 3D Printing – “ Slicing ” We used Tinkercad to make .STL files. Next we used a Slicer Software to “ slice ” our model into layer by layer instructions for the printer (called Gcode )

39. 3D Printing Concepts and Vocabulary Words Filament – Our “thread” for our final product Filament Drive – Moves the Filament to the Hot End Hot End – Melts that Filament so we can “draw” with it.

40. 3D Printing – Start Up and the Skirt Makes sure the filament is flowing Like squirting m ustard before putting it on your sandwich Photo by Josh Reichlin

41. 3D Printing – The All Important First Layer You want your print to dtick People have e mployed a variety of t ools to make that happen: Heated Bed Painters Tape Glue Stick Hairspray Even Superglue Rafts

42. 3D Printing – The All Important First Layer Why? Your print may fall off or move Precise Measurements – A curled edge may throw things off Your Nozzle could even knock the print

43. Design Considerations – Thin Walls Your object n eeds to be sturdy enough to support itself… and be moved.

44. Design Considerations – Thin Walls The 3D Printing service companies publish guidelines on Wall Thickness Varies for My Home Printing: Walls Supporting Lot of Weight– 2mm Normal Walls 1.0 – 1.5mm Detailing (such as Embossed Letters) – 0.5mm

45. Design Considerations - Bridging With the right speeds and temperatures, we can print over gaps! Just small distances - I tend to stick to 20mm-30mm gaps Find/Test Your Printer’s Capabilities With “Ultimate Extruder Calibration Test” http:// www.thingiverse.com/thing:9804

46. Design Considerations - Overhangs Overhangs – Supported underneath by one side Works when there is good overlap with previous layer Most printers can handle angles of 45 degrees or higher Photo Courtesy of Joel Telling, The 3D Printing Nerd

47. Design Considerations - Supports Overhangs too flat, bridges too far, object starts in mid-air? Supports are temporary structures that help the print

48. Design Considerations–Orientation You aren’t necessarily going to print your object right side up.

49. Design Considerations– Splitting Up Into Parts You don’t necessarily have to print it all at once

50. Design Considerations – Using Other Parts No need to recreate the wheel.

53. Getting Models – So MANY Resources Including PinShape , YouMagine , Yeggi … Martha Stewart! Need A Listing? Check out http://3dprintingforbeginners.com/3d-model-repositories/

54. Advanced Tinkercad – Importing Models You found and downloaded a model you like. In Tinkercad , click on Import , browse to the file and hit Import again.

55. Advanced Tinkercad – Importing Models It’ll bring the new object into Tinkercad and you can manipulate, add additional objects or engrave just as a normal object to make it your own

56. Advanced Tinkercad – Image Generator Allows you to engrave or emboss based on the content of an image. To start click on Shape Generators-> Tinkercad The Inspector has extra options for you to upload an image

57. Advanced Tinkercad – Image Generator It makes an object based on the image.

58. Advanced Tinkercad – Ruler Adds keyboard control to be more exact with the measurements Under Helpers you can drag a Ruler object to your Workplane . It’ll display the dimensions of your object. Click on a measurement and you can enter in exact numbers.

59. Advanced Tinkercad – Workplane Tool Under Helpers , the Workplane tool allows you to move the Workplane (our graph paper) Helps save some layout and rotation time

60. Advanced Tinkercad - Align A quick way to line your objects. Click on Adjust (in the top tool bar) and choose Align… Click where you want to align everything (Top, Middle, Bottom, Right, Left)
