  1. that does look odd, are you sure the core is fully seated in the carriage? Can you take a picture of the assembled core laying on the table? I would want to verify that you did not accidentally bend the core while installing the new nozzle. @gr5 might also have some input.

    Issue with PVA

    It is possible that I am being overly cautious with my cleaning routine - by cleaning the nozzle every few days. (When I do clean the nozzle, I only see specs of burned PVA, but nozzle is mostly clean) But no way can I get 2000 hours without cleaning. @kmanstudios what settings do you use for your Matterhackers PVA? Maybe the default UM PVA temps are too hot.

    Issue with PVA

    I suspect my issues are that my printer will run for several days, sit for a day, run some more...and so on. Not running continuously could be the difference. Additionally, I print a lot at .1mm layers, so maybe I am not moving enough support material though the nozzle.

    Issue with PVA

    When I run PVA on our UM3, I clean the nozzle every day or two, depending on how many prints I am running. To clean the nozzle I use the clear nozzle cleaning sticks sold by Ultimaker, which work really well. I set the core temperature to 220, push the plastic rod into the nozzle until the filament turns clear (indicated the cleaner material is moving through) then set the core temperature to 140. once it hits 140 (i call this a coldish pull) , I pull the rod out, usually bringing burned PVA with it. After a good cleaning, you should be able to see daylight through the nozzle when looking down. Also, I tend to use Matterhackers PVA for a few reasons: #1 is that UM PVA is always sold out, #2 is that it is less brittle, so when the nozzle inevitably hits a support, it doesnt snap like the UM brand does. Last thing is that if I am done with the PVA for the day, I put it into my air tight super dry box full of desiccant.
  5. Where did you source this from? Ive seen these before, but for a lot more than 4 usd. I was thinking they would be good for a diy laser engraver gantry (or something?)

    Post your latest print!

    We printed some laptop stands (wedges). Good news is they just BARELY fit on the buildplate - diagonally. We need (2) per laptop, so I decided to stack them with a bit of PVA in between for a tasty PLA PVA sandwich!

    Prosthetic Elbow

    Ha, not sure. I was worried it might be considered an advertisement for College Park.

    Prosthetic Elbow

    The company I work for just released the industrial design video of a new prosthetic elbow we have been working on! The video features a quick shot of our UM3 printing (a cylinder...because of course we had bad luck the day of filming...) and various prototypes floating around in the background - all printed on the UM3. Maybe future videos will include more shots of the Ultimaker... 😉 Mods feel free to move or delete this post if it violates the rules. Its just an exciting project that has definitely benefited from 3D printing, and the Ultimaker specifically. http://www.espire-elbow.com/

    NylonX

    Here is my latest NylonX creation. It is a bracket used to remove a steel core from a molded cylinder shape. Kind of difficult to explain, but this particular plastic molded part had a feature that had to have reverse draft, so it has a part of the injection mold stuck inside of it even after the mold opens. After we remove the part, we can push the part out the non-reverse draft way and make another part. Very time consuming, but it had to be done. Anyways, this part will replace an ABS part that only lasted (6) tries. Hopefully this one lasts longer. Otherwise, we have aluminum machined brackets coming in another week or so. Production must go on! 0.5mm SS nozzle 0.2 layer 6 walls 40% fill 260*C at the nozzle 100*C bed no cooling Ultimaker adhesion sheets Emergency super glue application to keep part stuck to bed 🙂 ~20 hours to print.

    Post your latest print!

    no, it was a bracket for a special fixtures used to remove a steel core from a molded cylinder. Ill post some pictures in my NylonX thread.

    Post your latest print!

    I printed some abstract art this weekend using about 200g of NylonX. Now I just need to build a display case.

    Ultimaker 3 Print cores jammed with Filament

    Sometimes I do that. But I really dont have much issues getting oils etc on the build plate. Occasionally if I get some stuck on PVA particles I might take it to the sink to wash with soap.

    Ultimaker 3 Print cores jammed with Filament

    Absolutely. I have a squeeze bottle of water stored next to the printer. a little bit of water on a paper towel after every-other print and it is clean and ready to go to. New application of gluestick and I can hit print. 🙂

    Ultimaker 3 Print cores jammed with Filament

    I always use glue stick, even for PLA. prints pop off just fine once cooled, and it just doesnt seem worth the trouble to risk an unstuck print. I have around 2k hours on my Ultimaker 3 and have not had this happen.

    NylonX

    Absolutely, I would consider this not be a good test - only some indicator. The carabiner was something i found on Thingiverse. Tensile testers use dogbone samples, and pull at a very specific rate in a straight line - I definitely do not expect this to hit perfect theoretical numbers, but it was weaker than I had mentally planned. The surface finish is strange, I cant tell if it is the carbon fiber or if there are some bubbles in the material (indicating water content). We have a device than can behave like a tensile tester, as soon as I find the fixtures for it, I will test some samples for fun.
