Week5 3D Scanning and Printing
Group assignment
Design rule test of 3D printer
Bridging Test
Angel test
Overhang test
Wall Thickness test
Clearance test
3D printer: Bambu Lab A1 Mini 3D printer and the Automatic Material System (AMS) Lite.
Bridging Test- All bridges from 2mm - 20 mm are good enough.
Angel test- Angles from 90° to 20° lookd good, but 10° slightly “spaghetti”，and 0° heavily and obviously “spaghetti”.
Overhang test
| 1mm overhang | OK |
| 2mm-5mm overhang | Slightly“spaghetti” |
| 6mm-10mm overhang | Obviously “spaghetti” |
Wall Thickness test-the minimum printable thickness is 0.4mm
Clearance test- 0.1 and 0.2 clearance cannot move freely
Individual assignment
3D printing - Cup
Following the tutorial to make a cup
Step 1 draw the 2D diagram as below with dimension
Step 2 use the tool to rotate
Step 3 make the handle with constraint as below
Cut the extra line
Draw a ellipse as below
Use the sweep as the sketch 2, make the handle
On shape 3D file:
STL file: cup-3D-priting.stl
3D Printing with Bambu :
Step 1 Download Bambustudio, and login
Step 2 import or drage the 3D print file, followed the defaulted setting
Step3 Slice plate checking if need support, fot this cup, need to add some “support”
Step4 click print plate to start, but found the printer not connected
Step 5 connect the printer
connected
Step 6 start printing
The cup printed

3D Scanning
With the recommendation from Ai, I will use "Polycam" for my project.
I download the App and sign up
The object I wanna Scan is the "Lucky bot", I spin the object the scan with Polycam.
I select the default setting as below, select " Photogrammetry"
Upload the images, and Polycam is processing
I tried many times, I found the video or pictures need to be sufficient, like 1-2 minutes video, with many times trying, I pick the one looks better.
The 3D Scanning picture looks good than i expected. Then I download the stl. File, as below,
STL file: 3D Scanning Luckybot.stl
Open from Bambu studio,as below
On the App, pictures looks more better. If I could upload a more longer video, or scan it slowly, the final 3D model will be better.
Update on 28th, Jun.
I still feel the one made yesterday is not good enough, I feel the main reason is the video data is not enough, so I tried another 2, with a longer video, around 1- 1.5 minutes, I upload the video from the website, and then I check the 3D scanning item from APP and download the Stl. File from APP
Sculpture Dog, see the image from the app.
Stone
A small conclusion by my experience, with the Polycan, we can make a scanning file very close to the actual object, as long as the data is enough; when transefer to Stl file, it looks not that good as the Scanning file
Stl. File for the 2 items:
STL file: Wangwangdui.stl
STL file: Stone.stl
