After my initial post, Testing 3D Printed Stamps, I decided to taking my findings and actually give it another shot. One of the things I had found was that flexible resin outperformed the other filaments and resins I tried. However, it was far too flexible and fragile. One of the recommendations for using flexible resin was to mix it with standard resin to make it more durable. I didn’t have the recommended resin at the time but I did order some to try.
Monoprice’s rapid resin does come in clear, but the yellow was $10 cheaper at the time I was ordering. Also, I’m still testing, so the transparency of the stamp material really wasn’t a concern.
I’ve seen 3D printed stamps around the various 3D printing download sites for many years. The results I’ve seen never seemed particularly good. For a long time the only filament you could print with were hard plastics and now that some flexible and alternative filaments are available I wanted to try printing stamps with them.
My mother, after seeing my doodles and watercolor post, suggested that I try making stamps, which sounded fun. I had most of the equipment from other projects to give it a go. All I really needed was the photopolymer. After ordering a bottle of COLOP photopolymer off amazon, it showed up a few days later (it wasn’t even amazon prime, so I was impressed).
My first idea was to shove it into my 3D printer. The whole idea behind my new printer was that it uses UV Resin, which is what a photopolymer is. Shine a UV light on it and it cures. It turns out that this stamping resin is so highly viscous that it’s barely a liquid and 3D printer resin is still quite liquid. I started pouring it into the printer and it was hard to stop it from pouring because it was pulling itself out of the bottle.
Well, I can tell you that didn’t go well. It was far too thick and the printer didn’t like it. After editing the 3D printer’s program to see if I could make it work, I found the cured photopolymer wasn’t sticking to the platform and just ended up making a mess.
Just under a year go I contributed to an Indiegogo campaign for a SLA printer called Bean and it finally showed up at my doorstep last week.
This printer has been basically been running non-stop since it showed up. I’m having a lot of fun with it. So far I’ve mostly been printing little figurines from one of my favorite 3d artists, who recreates a lot of characters I like. I know his models are good and this has let me figure out all the ins-and-outs of printing with resin.
This weekend, I promised my co-worker I would spend some time doing some painting on some of the 3D items he requested. Why? Because I volunteer myself for everything.
I’ve done many many paintings, but 3D Prints are a bit hard to paint. First, they have a texture from the plastic layers (unless you do some post-processing). Second, they’re 3D, and unlike a painting, they don’t have any definite lines where the paint should stop. Third, I didn’t prime the object, because I printed it in the character’s main color so it took many layers to cover the green plastic. And last, I didn’t give it a clear coat to lock it all in, so I’m just waiting for him to accidentally scrape some of the paint off.
Basically, it can easily come out looking very messy. My co-worker seemed to really like it this morning when I brought it in, so maybe I’m being too picky. I hope it gets easier once I get a few more painted.
I finally printed something for my desk. Everyone else has little chotskies all over their desks and mine just has paper everywhere. So I browsed the 3D repositories for something I’d like and found Roger Smith from American Dad on thingyverse.
As soon as John (the guy I 3D scanned) saw it on my desk he took it. What a jerk! This is why I can’t have nice things. And why I shouldn’t bring my 3D prints into the office.
My coworker John was excited when I came in this morning. “WHERE IS IT?” he shouted as I passed his office.
I had been annoying him with different methods of 3D scanning. I kept taking him to one of the big open rooms in the office so I could walk around him and take photos or use different types software on my phone to see what would work best. I was excited someone was willing to let me do it, turns out not many people want to be 3D scanned. After many attempts, we found nothing was really working well.
Finally, I remembered I had bought a Structure sensor for my iPad years ago. I had the sensor but couldn’t find the darn cables anywhere. I ordered new ones and as soon as they came in I bothered him again to stand perfectly still in the middle of an open room while I slowly walked around him letting the software do its thing.
I dumped the results to my workstation and found we finally had a usable result.
So this morning when he was shouting at me, I produced the mini-John printing.
It could use some work, especially on the top of the head. But, overall, I was pretty happy that we finally got it to work. I still need to work on full body scans. We tried that as well but the room we were in was making it pretty difficult. I told him on a nice day we’ll have to go to the parking lot and give it another shot.
Over the weekend, I got to sit down and do some playing with the new 3D printer. I have to admit, the Ultimaker 3 is pretty amazing, especially when I compare it to my old machine. Once I got it up and running, you pretty much just push the button and it does everything for you. So I loaded up a Tiny Rick 3D file (by 3D Print Guy) that I downloaded from MyMiniFactory.com. His prints are pretty stinking cute and I think I’ll be watching his account for new files.
The new printer prints with water-dissolvable supports, which means I can pretty much print anything. What used to be impossible (or just a huge pain) to print is now not an issue. I can print a lot of these on my old printer also, but I’d have to sit there and cut away a lot of material it needed to print in order to prop things up while it printed.
So now, things come out looking like this:
(You can thank me for that tushy on your screen later.)
Once the print is done, it’s just tossed into a bucket of water and all the clear/white plastic will disappear within a few hours.
The only downside to 3D Printing is the patience required. This machine is super easy to use, but printing with such detail takes literally forever.
Over a day to print a 5-inch statue… YIKES! At least this printer is just a set-it-and-forget-it type of thing. I think I got the print started early enough yesterday that it should be done printing before I get home from work today.
I also spent some time fixing my old machine. The replacement parts came in and now I have dueling 3D printers in my basement.
