6. 3D Scanning and printing¶
Instruction¶
Group Assignment
Individual Assignment
- Design and 3D print an object (small, few cm3, limited by printer time) that could not be easily made subtractively
- 3D scan an object, try to prepare it for printing (and optionally print it)
What I did in Week5¶
- Test the 3D Printer : Angle, Overhang, Bridge, Wall-thickness, hole test → Group Assignment
- Design and 3D print an object → In this page
- 3D scan an object, try to prepare it for printing → In this page
What I want to print by 3D printer¶
is light bulb because it is the symbol of the invention and prototyping and ideation
Design Light Bulb¶
Design by Fusion 360¶
- Sketch and Extrude cylinder
- Create Sphere and join to cylinder
- Fillet the circle between cylinder and sphere
- create cylinder from the bottom
- thread
- chamfer the bottom edge to create bulb bottom
- cut out a little bit smaller sphere from the sphere
- create coil primitive to be firament inside the bulb
- create rectangular under the firament to support printing
- create a hole from the bottom to illuminate inside the bulb by LED or Light
- conbine the whole body
- project the ourline of the light bulb and sketch a groove between upper and lower by “revolve”
- cut out the groove sketch
- finish the design. It is difficult to shape in subtractive because of the filament inside the bulb.
- export to Cura by “save as mesh”
- move on to Ultimaker Cura and adjust the setting
- check whether each mesh can print out from the bottom by “preview”
3D Printing¶
[Printing Trial 1] :¶
The PLA we used : Jr.PLA XYZ print Clear Tangerine 600g
- failed to print the object clearly because PLA was broken dring printing
[Printing Trial 2] : Change the different type of PLA¶
- But, fail again to print the object the clearly
[Printing trial 3] : Change the different PLA which was proven operational¶
- but in this case it came off the object during printing because the basement was too narrow and the adhesion was not enough.
[Printing trial 4] : Set “Brim” at “build plate adhesion” in Cura and try again.¶
- But unfortunately, even “Brim” was not enough for the bottom to stick to the plate and fail to print.
[Printing trial 5] : Set “Raft” at “build plate adhesion” in Cura and try again.¶
- Printing
this shot is that the printed object is not “subtructive” evidence! :)
- done! Here is hero shots.
- Lighting!
Put LED into the printed light bulb to illuminate to the filament in the inside.
Try different LED colors
3D scaning¶
Software I use¶
I decided to use iPhone 13 Pro as Lider (3D scanner) because it has the most reasonable and newest Lider sensor.

the object I choose¶
the lightbulb which I printed out in 3D printer JUST NOW
Scaning
the scanning data
- export to sketch fab and prepare for printing
What I learned in this week¶
group/individual assignment
- This is the first time I’ve designed my own material and had it output on a 3D printer.
- It turns out that a 3D printer does not necessarily output exactly what I design on my PC throughtout a variety of tests
- We should understand various traits of the 3d printer we use and design the data to be able to output without problems
- It’s very fun to watch the moment the bits on the computer turns into an atom in the real world.
