Here’s the quote that’s of interest (bolding is mine for emphasis):
By the way, if you remember my first video on the VORON you’ll know that I had huge problems with the Carbon Fiber Nylon that I used for my parts because they slowly deformed over time. People were asking if I already fixed that. Well, I could have just printed all parts from ABS and be done with it, but that’s not how I and also you will learn a lot. Instead, I’m currently working on a material creep test that I came up with. For that, I printed test pieces of a bunch of different materials that I load in compression by tightening a bolt with a torque wrench. Torque and the pretension in the bolt are proportional to each other. So, when the material creeps away under the load, the pretension will reduce, and I will be able to retighten the bolt again by some amount that I measure with these dials. This is what I’ll be doing in regular intervals at ambient and at slightly raised temperatures to compare how different materials behave. If you have any thoughts on that procedure, please let me know and also make sure to be subscribed and have selected the notification bell to not miss the results. Despite these tests that are ongoing, I actually got the Carbon Fiber Nylon to work as well. How, you might ask! Well, I annealed some of the parts at 160°C for two hours and had them now installed on my VORON for several hours of high temp printing without any sign of deformation so far, pretty impressive! The cool thing about annealing Carbon Fiber Nylon is, that it basically doesn’t deform during that procedure in contrast to PLA! I’m still not sure what I’ll be using for the re-build and will decide that after I finished the creep test.
I have procured a chinese blast oven, now sitting in my garage. Just $300, delivered. I have used my own temperature probes to confirm that it is working correctly. Current plan would be to print in the X1C and let ti cool to ambient inside the X1C. Then, remove the print (unsure whetther to leave it attached to the garolite build plate) and then dry it at 160C for maybe 2 hours (as that number if what worked for stephan at CNC Kitchen). It would likely auto-release upon cooldown unless I were to secure it witih vision miner bed adhesive.
