3D Scanning and printing¶
Group assignment¶
2023¶
You can find all group-assignment in our group page
This week we worked on learning printing parameters.
We use Makerbot Replicator 2
We printed same sphere but with different mashing parameters and printing parameters.
Then we measured weight of prints, and compared with program numbers.
With buildplate, without and buildplate apart.
Then we made cardboard plate to make stand for prints.
And finally we have this.
2025¶
This week we tested different 3D Printers that are available at FabLab Armenia, with help of our instructor Areg.
I was testing Elegoo Neptune 4 max.
It is nice printer with big build volume (420420480mm) and awesome printing speed.
I used Orca Slicer to generate g-codes for testing.
I found my printer in program
I will use built-in tests.
Temperature test¶
First test is temperature test
We are trying to different materials for every test , PLA and PETG
i started with PLA , i am testing printing temperature from 190 to 230 degree.
After generating object with my parameters program doesn’t generated the up plane, so i needed to repair it.
Program found error and repaired it
Here is my model i want to print
So i sliced it
and exported G-code
As we have 2 same printers at FabLab, i made same test g-code for PETG, and printed it on second one.
I am testing PETG from 230 to 250 degree.
So i started printing (lime is PLA, white is PETG)
and got results
VFS test¶
I did same VFS test for PLA and PETG
And started print
Max Volumetric Speed test¶
Same steps for next test
Tolerance Test¶
Results¶
With help of Areg, I made table for Elegoo Neptune 4 max optimal parameters parameters
| Test | PLA | PETG |
|---|---|---|
| Temp. Test | 190-215°C | 250°C |
| Volumetric Flow Test | 15mm^3/s | 10mm^3/s |
| VFA | 90-450mm/s | 165-300mm/s |
| Tolerance | 0.05 mm | 0.05mm |
Designing Model¶
I started from creating cube, using “Createan additive primitive” tool
Then I set parameters of my cube, and position. (when setting position, very important to attach your body to “something”. I attached to X axis)
Then I cuted Sphere with 33mm radius from my cube, using “Substractive Sphere” tool
Let’s use some math and geometry to count radius of circles cube sides, to see what size i must set my inner cube
Off course, instead of that you can use your computer, but i don’t trust computers)))))
After making sure my computer is not lying, lets design inner cube
However, i will count it my myself))
I decided to take radius of cube 25, which i s more than 21.54mm as i need, so diameter will be 50.
Now, I counted what size must be my cube sides
Now i will make Sphere and Boolean-Cut it from my inner cube
Printing¶
2023¶
I am using Sindoh 3DWOX DP200 printer
In summary, the 3Dwox and Replicator 2 are high-quality 3D printers with advanced features and better build quality compared to the more affordable Ender 3. While all three printers are capable of producing high-quality prints, the 3Dwox and Replicator 2 are better suited for experienced users who need advanced features and higher print quality, while the Ender 3 is a good choice for beginners or those on a budget
Unfortunately, printer broke one of my outter cube side, and i stop printing.
I’m gonna print it with 100% density
2025¶
As i have new Bambulab Carbon X1 Combo I decided to print previous designed model on it
Firstly i downloaded stl model from my website, and imported it in Bambu Studio
Sliced it
and printed
After removing supports
I finally got my cube in cube (which is absolutely absolutely can not be easily made subtractively)
3D Scanning¶
I decided to scan the model of DaVinci’s catapult, we made in our laboratory with middle school children WITH POLYCAM program using my smartphone
As you can see sizes are not scanned correctly
here is link to watch video i’ve exported.
Then i scanned myself with Kinect usind Scanekt program.
And I imported it to FreeCad
Look mom, I am in FreeCad))))

Conclusion¶
In summary, We learned about printing parameters and tested various settings on a Makerbot Replicator 2 to produce a sphere. I also designed a cube with a subtractive sphere and printed it on a Sindoh 3DWOX DP200. Although one of the outer cube sides broke during printing, I was able to print a replacement with 100% density. Additionally, I attempted 3D scanning with PolyCam and Scanekt programs, but encountered size accuracy issues. Overall, I gained valuable experience in 3D printing and scanning, and learned how to troubleshoot and find solutions to issues that arose during the process.
