Week 04 | 3D Scanning and Printing
This week's assignment is to 1) design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively and 2) 3D scan an object.
Things I did for this week:
- 3D scanned my bunny pendant with both Puma Plexus from REEF and Scaniverse on my phone
- Design a lattice-structed airpods case for my airpod
This is a painful week for me. Since I joined the class late and haven't had a chance to catch-up on CAD week, I am still at 0% of CAD skillset. Let's hope I survice.
3D Scan with Puma Plexus (REEF)
During the 3D scanning office hour on Wendesday after class, I gave a try on the Puma Plexus scanner from Reef. I put my cute bunny pendant on a black board as intructed and scanned it, but the scanner kept give me the alert that it couldn't match the object. I had to run after the workshop so I didn't get to finish or debug or even document, but I was assuming the issue is caused by the way I placed the object since a very big part of my bunny is covered on the black board.
I returned to REEF on next Monday to finish the scanning pratice. This time to avoid the blind spot, this time I hanged my bunny on a light stick so that I could an get all the surfaces of it.
This time it went smooth. I took 3 scans to get the outcome. It was satisfying to watch the object appear on the screen.
The scanned outcome looked like in on the Artec Studio:
I followed the instruction on REEF's laptop to clean up the model and get the materials, however the process wasn't very handy and intuitive for me, and the file was very heavy. I recalled for past projects I used a free software called Scanivers on my Phone. It was pretty handy, I heard it now has some new feautres so I decied to try it out with the same setting. (Maybe the free software will beat the expensive machine )
3D Scan with Scaniverse
The software was easy. I just downloaded, opened it and scanned it around the object. This is the outcome:
The software comes with post-processing functionality in it which allows for immediate export as sharable medias (videos, images), and here is the process:
I will say personally I feel like Scaniverse is to some extent better than Puma Plexus, for it:
- Does not require a set up
- Can user-select different scales
- Has in-app editing and customization functions
- (might not be true but) more photorealistic
- Smaller but various file types
I guess Puma Plexus might be better for other use cases other than scan small objects.
