3D Scanning and Printing



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

Group assignment:

  • Test the design rules for your printers
  • Document your work and explain what are the limits of your printers


Software used:

  • 1. Autodesk Fusion 360
  • 2. Ultimaker Cura
  • 3. Qlone 3D Scanner

Machine used:

  • 1. Ultimaker Extended 3D Printer



1. 3D Printing


First, to print a 3D object you should have a 3D design to print it.
Therefore, I did a simple 3D roket design by using Fusion360. I saved the design as stl file.



Sketchfab


After finishing the design, I downloaded Ultimaker Cura software.
This 3D printing software is used to set all printing settings before puting the design in the 3D printer to ensure that the print will be clean and successful.

The following images shows the settings.


Then I clicked on Slice then Preview and the result is shown in the following image.
The software added support at the sides below the wings of the rocket and below the thruster.
The purpose of the support is to prevent the material while its hot from falling down because of gravity.


Then I saved the file and put it in a flash and insert it in the 3D printer .


Ultimaker Extended 3D Printer

The first thing I did before starting printing was to change the material used in the printer and replace it with another material with different color. In this assignment we used the PLA material.


Steps to change and Load Material in Ultimaker Extended 3D Printer

1. From the main menu choose Material/Printcore 2. Material 1 3. Choose change then the material will be removed automatically

4. Place the new material on the holder and choose the type then insert it in feeder1 and confirm 5. Material Extruded 6. Confirm

7. Choose Return then Print 8. Finaly it started printing after heating the plane (I choosed this pink color to print the angle test design for the group assignment)

The results after printing. I choosed silver color for my rocket.

Second design

I did a hexagonal cup design in Fusion 360.
I wrote the word hope inside it and I extruded the word. Also I added a ring at one side, and I made it as a chain. Chains are hard to be done in subtractive machines like cnc milling machines and it could be done easily in 3D printers. Then I saved the design as a stl file


Sketchfab


Then I opened the design in Cura software to set all print settings.



After that I clicked on Slice then Preview and the result is shown in the following image.
The software added support to the ring.



I saved the file from Cura and put it in a flash then insert it in the 3D printer.

And here is the result

2. 3D Scanning


I used the Qlone app to scan 3D objects.



To scan with this app, I printed the Qlone Mat and I put the object I need to scan on top of it.



Here is the result. 3D scanning is hard for me because I cannot keep my hand stable for long time.







Group Assignment


Angel Test
Group Page Link

I downloaded the STL file of this design from Fab Academy website.
Then I opened it in Cura and set the print settings as shown in the following image. I didn't click on Generate Support because I want to test the 3D printer we have in the lab. I want to see the result of 3D printing different angels from a straight line to a 90 degree angle.


Then I clicked on Slice then Preview.


Finally I saved the file ia a flash and insert it in the 3D printer

And here is the result




As shown in the previous images, the material is falling down a little in last two degrees as they approximatly equal to 90.
