Remember when we got the Prusa i3 Mk3? Well, even if you don’t remember, you might be excited to learn we just got the Multi Material 2.0 upgrade kit, and it’s been installed, and we can now print in multiple colors. Neat!
This is the printer that we won in the Hack-a-Day contest about 2 months ago. It arrived at my house last night, so I decided to open it up and inspect the contents. That’s when I saw it…
I lifted it out of the box and discovered that the left Z axis motor mount was also broken:
Finally, printed parts installed…
Alas, it appears that the lead screw is bent- you can see it wobbling when it rotates. I’ll be contacting Mr. Prusa for a replacement…
Wow! Wow! Wow! Mark our 3D Printing Champion is always busy, either building 3D printers, or designing and printing parts. He 3D printed a Prius Hatch Release Switch Cover and entered it into a Hackaday Contest and won an Original Prusa i3 MK3 3D printer for the space!
As we just got one of these where I work I can vouch for how nice this machine is. I built my first RepRap Prusa Mendel i2 about six years ago, and before that used a MakerBot Cupcake, so I’ve seen some evolution of desktop FFM printers. The first thing you’ll notice (or, don’t notice) about the MK3 is that it is quiet. Really quiet. Like, in our office we have to look at it to see if it’s running. It’s that quiet, thanks to the Trinamic stepper drivers. The PEI powder coated magnetic build surface is also nice, and… well, I could go on, but let’s all thank Mark for being awesome and winning this amazing new printer for the space!
Last minute decisions work out once in a while. For example, I was going to be at the Makerspace booth at the Milwaukee Maker Faire for the weekend and wanted some examples of the sorts of things you can use a 3D printer to make, so I grabbed the usual collection of sample prints, and then I thought, “sure, why not?”, and loaded the Van de Graaff generator into the car. It sat on the floor in the booth for about 1/2 of Saturday and I was getting a little bored, so I moved it closer to the foot traffic and plugged it in. Wow! Kids and adults with stunted emotional development went nutz! They were zapping themselves and each other as if it were more fun than painful.
Then I found a plastic bucket and the fun really started. We had kids and many adults who were definitely much too heavy, standing on the bucket and making their hair stand up with moms, dads, boyfriends, girlfriends, husbands, wives, partners all taking pictures. I had to move one gentleman who was breathing oxygen from a tank away from the machine. Fortunately, no one fell off the bucket or caught on fire, and next year we’ll do it right and take a block of styrofoam for people
to fall off of to stand on.
Even Gordon couldn’t resist!
Last year Son of MegaMax (a 3D printer built at the Milwaukee Makerspace) went to the Faire. This year he had two companions to keep him company- an extra-beefy printer being built by Erich Zeimantz: MiniMax XY. MMXY isn’t complete yet, but promises to be a super high quality, high speed printer. He’ll be operational at next year’s Maker Faire. SoM also brought his big brother, Ultra MegaMax Dominator, named that because he is ultra, mega, maximum, and he dominates.
UMMD and SoM rotated between the booth and the dark room where the both printers’ UV lighting and fluorescent filament was a big hit.
We had a few things besides 3D printers at the booth. Tony brought in some Bismuth crystals to give away, and surprisingly, they didn’t all disappear in the first hour. Tony thinks people left them because the Makerspace logo on the info board on which the crystals were sitting looked a lot like the skull and crossbones that usually indicates poison. The crystals do have an other-worldly toxic look about them. Oh well…
Marcin’s LED signs on the table at the booth and hanging above the entrance to the Dark Room were also very popular and hard to miss, though I managed not to take any pictures of either. The one above the Dark Room was so bright that if you saw it, you’ve probably still got its image burned into your retinas.
Everyone involved had a great time and we’ll be there again next year with even more cool stuff!
Sometimes you see amusing things at the space. Take for instance, this lock on the bathroom stall. The black piece is actually 3D printed. Yes, someone took the time to measure, and model, and 3D print a rectangular bar to fix the bathroom stall door lock.
Never mind that a piece of wood, or plastic, or metal could have probably done the job in much less time, sometimes you just need to 3D print a replacement part for a bathroom stall door and you bust out the 3D printer and in a matter of hours you’ve got the part you need!
