3.4.2 Fabrication

So for my model, I decided to choose the easiest thing I had on hand to scan that I carry everywhere: My Head.

To start off, the creality scanner spat this out. This model was pretty good! Though there were a few problems I needed to fix first, namely the flat part on the head, the mangled right ear, and the not-so-flat bottom section of the model. Simple enough for MeshMixer to fix with me

After a while in MeshMixer, I repaired the ear a bit, fixed the flat spot on my head (Since the scanner was having trouble capturing it because of the darkness of my hair and the lighting in the space) and added a base for easier printing. However, I was able to take advantage of something else in the space too, the Prusa’s color change feature!

So here it is! My golden idol of my own head! Printed at .1mm layer height using our Marble and Gold PLA filament, with a grand total of 36 hours to print.

 

So why pick my own head? I can scan literally anything using the Creality and/or photogrammetry. For starters, the source of this model is ME, so there’s no copyrighting or citing, and because I figured out the creality basically by myself, I was able to get a fantastic scan of my own head along with some other things in the space. Without that tool I most likely would not be getting as good as a scan as this.

3.3 Design

So there’s not much I can say about designing my head, since this was sort of an alternate project, so I’d rather go over the creality scanner and my struggles with it instead, then write a small blurb about scan cleaning and printing at the end.

Is the creality worth it? I’d say yes. Its a very slow process, the software sucks, and the only documentation is in my head, but the scans are high quality.

Working with the scanner was pretty hard at first. When I first cracked it open, I was sort of amazed about how clunky the software was, how horrible the first scan was, and how tough it was to set up. It needs USB 3.0+ and wall power to even run, so it’s hardware and location locked, the turntable needs either a bunch of AAA batteries or to be plugged into the scanner itself, and the object choice was odd.

But eventually I broke it.

I got through creality’s stupid software, and through a few rounds of testing, I got a good scan off it. The soda can. It wasn’t on the turntable, but it was good to me.

The turntable issue was also resolved, doing the pear and removing the base, allowing the software to clean itself up, and exporting it, the pear model came out almost identically, +/- some polygons.

Then was the ambitious part. Using a tripod and staying a little late, I slowly turned myself around, scanning my head all around before I was left with a model:

This model was fantastic, mostly. The right ear was absolutely mangled, and it had missed a big portion of my head, which I had to fill with Meshmixer. For a first scan of a person, it was very very promising.

Printing was another challenge, I definitely should have used support material for the chin, and maybe selected something higher than 0.1 mm layer height, but after a day and a half of printing my head, I think it was worth it.

3.2 Exercise Reflections

3.2.1 Digitizing and Mesh:

For this I took the regular bunny model and added some arms and legs to it, basing it off a certain boss from a game called Bloodborne, named Ludwig the Accursed, a gory horse monster (Below):

And I decided to add the ‘Tilted Spheres’ pattern to it and throw it into fusion. Just something simple to work with meshmixer on, since I already scanned a rather large object and edited it, so this was a better practice:

 

For some reason, fusion is not showing the correct texture in the preview window, so here’s a simple render.

3.2.2 Surrealism through Booleans and Other Operations:

 

I went a little off-topic with this, but I wanted to make something interesting using Booleans. So here’s a ‘Gear Tower’ using two tall gears, and a sphere to make a sort of 4th Dimensional Gazebo. I was going to make a gear cube instead, but this seemed to be a little more fun, and printing out a functioning gear cube would be a lot of trouble.
