HTMA Week 4: Bocchi and Fumo
Published: 2023-10-043D Printing
This week’s focus is on 3D printing and scanning. Since I do digital sculpting in my free time, I thought it’d be cool to print one of my models. Due to material and time constraints placed on us for this week, I chose a model that is on the simpler side and wouldn’t require much material to capture its details:
I had split the model such that the hair and hair cubes are printed separately to avoid printing a huge amount of unnecessary supports.
For printing, because it has dissolvable supports and I don’t want to deal with getting supports out of tiny crevices (especially behind the hair), I chose the Stratasys printer.
The print took about 6-7 hours. However, of the way the support was built, the ends of the hair on both sides moved mid-print, causing that area to fail.
I also did not have the foresight to make the hair strand thicker at its stem, so it broke off after a while. I used superglue to glue it back on.
In the end, it turned out pretty good.
3D Scanning
For my 3D scan, I decided to use AliceVision to scan my fumo plush doll. I tried a simple workflow of recording a video going around the doll, and just extracting the frames via ffmpeg and feeding all the frames into AliceVision. The whole process took about 3 hours in total for 957 images, and the results are frankly not great.
It seems that more data doesn’t necessarily mean a better scan. Next time I’ll try to just take a bunch of good pictures instead of going with the lazier route, since other people have way more successful scans of their objects with fewer pictures.
