2. 3D Printing
Lesson 2
Section Topics:
-What is 3D Printing?
-How does it work?
-Examples of 3D Printing
-Brief History of 3D Printing
-Open Source 3D Printing
-RepRap
-Makerbot - Replicator
-Tinkercad

3. What is 3D Printing?
-'Additive Manufacturing'
-The process of making a 3D, solid object of almost
any shape from a digital model
Lesson 2

4. How Does 3D Printing Work?
-Basic Process:
-Designed using 3D modeling software
-Sent to the machine
-Design assembled layer-by-layer
-Considered distinct because it uses an additive process to create items,
as opposed to a subtractive process
-The difference in the main types of 3D Printing mostly comes down to how
these layers are assembled
Lesson 2

5. Lesson 2

6. Brief History of 3D Printing
Lesson 2
-Chuck Hull
-'Stereolithography'
-Created the first 3D Printing Machine
-Developed the STL file format
-Devices continue to get smaller, faster, and cheaper

7. Open-Source Printing
Lesson 2
-RepRap
-The first 'self-replicating manufacturing machine'
-Can print another fully-working version of itself
-The designs are free to share and use, including
the design of the machine itself

8. Open-Source Printing, Cont'd
Lesson 2
-Makerbot Replicator
-Founders are from the maker community
-Provide completed 3D Printers
-Help created Thingiverse

9. Getting Started With Tinkercad
Lesson 2
First, visit the official website at https://tinkercad.com/
Next, click the blue 'Sign Up For Free Account' button in
the top-right corner of the screen

10. Getting Started With Tinkercad
Lesson 2
The following window should pop up:
Fill out the information and create your account!

11. Getting Started With Tinkercad
Lesson 2
Welcome to your Dashboard - To create new projects, simply
click the 'Create Project' button on
the sidebar to the left
-This creates a brand new
workspace which you will use
to try out the concepts
discussed, and ultimately to
create your designs
-At one point we follows along with
'Lesson: Making Holes'
-at this point you will just simply
return to your dashboard to
select the lesson (seen in
picture)

12. Lesson 2
Tinkercad Lesson Topics:
-Basic Movement and Camera Controls
-Object Interaction
-Inspector
-Object Manipulation

13. Moving Objects
Lesson 2
-Objects can be moved by either clicking and dragging, or using the
keyboard arrow keys
-Note how changes in distance are displayed - helpful!

14. Moving Objects
Lesson 2
-Objects can be moved by either clicking and dragging, or using the
keyboard arrow keys
-Note how changes in distance are displayed - helpful!
-Objects also 'snap-to-grid' to maintain accuracy in moving things
without being too sensitive to mouse input

15. Lesson 2
Moving the Camera
Two Primary ways to control the camera:
-Use the navigation located in the top-left
corner of the screen
-Hold down the right mouse button and
move the mouse in the desired direction

16. Making Holes
Lesson 2
Orange area shows where the hexagonal
prism should be placed
Correctly placed hexagonal prism

17. Lesson 2
Inspector
-Before finishing the wrench, we take a
quick look at the 'Inspector' window
-When an object is selected, the Inspector
allows you to either color it or make it a 'hole' (to
remove an area in the shape of the object)
-The key to building more complex shapes is
learning how to combine solid and hole shapes
together

18. Lesson 2
Hexagonal Prism is designated a hole
Both wrench and hole selected via shift-clicking
'Group' button pressed, and the
wrench is fixed!

19. Lesson 2
Object Manipulation
When selecting an object in Tinkercad,
the various symbols around the box
might look intimidating.
In the next slide, you will be shown
what these dots and arrows do, so you
will be able to make your designs much
more interesting!

20. Object Manipulation Cont'd
Lesson 2
Arrow: Raises/lowers objects off of the
workspace depending on direction pulled
Upper White Dot: Makes objects
taller/shorter depending on direction
pulled
Lower Dots: Extends/compresses objects
in the direction based on the dot being
pulled
Curved Arrows: Rotates the object

22. Object Manipulation Helpers
Lesson 2
Helpers: Establishes workspace and adds a ruler
Ruler: You can set dimensions. Tip - be
sure to place it away from your object
Curved Arrows: Rotates the object

23. Object Manipulation Helpers
Lesson 2
Helpers: Establishes workspace and adds a ruler
Ruler: You can change the workspace
orientation. You can press W and click
outside the workspace to return to the
original workspace setting. Tip - use the W
key to select workspace.

24. Object Manipulation Helpers
Lesson 2
Adjust: Align text and “mirror” objects Align: This is important tool. Use it!
