Good Morning from my Robotics Lab! This is Shadow_8472, and today, I am taking a little side quest to try out some techniques so I can paint my Raspberry Pi case and have it look good<\/em>. Let’s get Started.<\/p>\n

I decided to paint one or more of my old test prints. The first two were an acrylic paint straight onto the plastic. It didn’t work all that well. I couldn’t even get a small piece devoid of any brush strokes, and I want a smooth finish. On top of that, I was able to easily scrape off part of the paint with my finger nail after it was fully dry.<\/p>\n

My next step took the rest of the time for the week. I moved over to a goal of spray painting, so I printed up another pyramid from when I tried to figure out if the percent completed was in terms of time, z axis, or plastic used.<\/p>\n

I was thinking of testing both sanded and unsanded surfaces, so I was going to print it twice, but I cut back and only sanded half of it. I still have the original around, but I wanted to leave that one alone as sort of a memory piece. Printing it again reminded me of how difficult the raft was to get off.<\/p>\n

After getting most of the raft off, I got out the sandpaper, going through grits of 80, 150, 220, 320, and 600, using water for the fine grits on “waterproof” paper, and I actually got it pretty smooth. I did get the stubborn part of the raft off. After going back and forth on what part of the model to mask off first, I decided on using some blue painters’ tape to mask off the very top and dangling the whole thing off that. I applied two layers of white spray paint, including the bottom (primer included in paint). I let it sit for a day over Sabbath. After it had the recommended 24 hours to dry, I masked off the rest of the pyramid body and painted the capstone yellow.<\/p>\n

As I peeled back the masking, I saw a few spots where I didn’t make sure the tape was perfectly creased in there and it leaked in. Lesson learned: use your thumbnail ensure the quality of your masking.<\/p>\n

In the end, I like the smoother sides. The little ridges from printing poke out a little, and I’m not sure if they are catching dirt or wearing through, but I think it may be worth it to put the bit of extra effort to make the final product just that much better.<\/p>\n

Final Question: I’ve been thinking of including a sub-title for multi-part projects. This one would have been something like: “(Side Quest: Painting Skills)”, but that makes it harder to just edit the URL to jump to adjacent posts. I know I don’t likely have enough regular readers to warrant this question, but should I include subtitles?<\/p>\n","protected":false},"excerpt":{"rendered":"
