6. 3D Scanning and printing¶
In this week I will be working on 3 main projects
- Indivdual Projects
- To design and 3D print Object that has the following specifications:
- Undercut
- Overhang
- has nested parts
- To design and 3D print Object that has the following specifications:
- Group Assignment
- To test the design rule of the 3d printers
Theoretical Aspects¶
by conducting a small reasearch I found these useful images that can illustrate the difference between subtractive manufactoring and additive manufacturing:
what I mean with undercut and overhang:
3D Printing Technologies:¶
and from the 3d printing workshop that was conducted on the lab by the Engineer Loay AlKooheji I have learned the following: - Continuous Liquid Interface Production (CLIP)
- Selective Laser Melting (SLM)
- Binder Jetting
- Stereolithography (SLA)
- Digital Light Processing (DLP)
- Fused Deposition Modelling (FDM)
3D Printer Limitation¶
- Bed Size
- Heated Bed
- Nozzle Size
- Layer Height
- Printing Temprature
Slicer Properties¶
- Infill Percentage
- Infill Type
- Shells
- Orientation
Design and 3D print an object¶
for this task, I thought about printing my version 1 of my robot that I have designed in week3. this design can only be fabricated by 3d printers as it has undercuts, overhang, and nested parts and all of those sepecifications cannot be done subtractively by cnc machines or fine milling machines or laser cutters So this was the final outcome: as I have adjested the design by making the hand and neck thicker:
I faced a minor problem on saving files as I made the robot with some parts and then assembled them together so when I tried to save the file as stl, all parts saved individually so I googled the problem and I found out that when I select save as stl, an option button will be displayed so by clicking on I have to select :
By using Slic3r Prusa Software
Printer’s Settings¶
Changed the properties based on the material and the printer we have in the lab as well as the desired outcome:
and then I clicked on slice now and this was the result:
the result¶
the result was accceptable however the balljoints of the arms didnt work well and it turned out that I have scaled it very small
so I decided to scale it bigger and try again and this was the final result
Scanning an object¶
for this part I have done it by using QLONE app on my iphone and by following the guide of the app
lets start first with what is Qlone
and this video explain how to use Qlone:
you can download the application through this website Qlone
and if you have an iphone you can search on the app store for Qlone and you will find it
this is the result
