Hiya, I know very little about the physics of creep as we've just started studying this in class... and I doubt we will go into much detail, but I had a question. In class the images and examples of creep in lattices show that the metal ions shift over so as to align themselves into the correct lattice shape. However this seemingly is breaking the 2nd law of thermodynamics which we have learnt to be that systems go from a state of order to disorder. However to my understanding it is seemingly doing the exact opposite! I can't imagine it actually breaks this law, so can anyone explain how it doesn't break the 2nd law of thermodynamics? Any help is much appreciated!
Im looking for perspective or empirical evidence regarding this issue.
Cliff Stamp's advice to de-stress (?) the cutting edge makes sense to me - you want to remove the deformed/weakened/fatigued steel because it loses structural integrity.
An accessible example is bending a paper clip; if you fold it over itself enough times it with break.
However, this seems to contradict other anecdotal advice that burr formation does work harden the steel, and the general approach to creating a burr when sharpening.
So, does forming a burr lead to work hardening the steel? And, how does using a honing rod/knife steel, or quick touch ups on a whetstone affect edge retention & chipping after repeated use?
Are there any know resources about steel deformation removal vs work hardening & edge rention?
I was asked which of the two is more prone to creep and it got me thinking. I assume it's related to the structure of the material's grain, but that's already getting deeper into materials sciences than I'm familiar with.
Seems to me that Kavvy has been bussy building a defamation lawsuit against himself and handing it to Ethan on a silver platter. He has since been deleting his tweets and post, but the Internet is forever KavKav, and your post have already made their impact. He has been: -posting defamatory statements...-encouraging defamatory info for money ....-causing banning with spamming (costing lost revenue).....-attempting to suppress sponsorships...-and perhaps encouraging swatting?
Hi everyone, I've noticed that the bed mesh on my Ender 3 shows this ridge going left to right along the middle, with a peak in the middle left. After flipping the bed from the PEI to the glass side, the same thing remained.
Regardless of how I level the corners, when I get it as flat as possible roughly the same relative differences remain as pictured. I've tried with all 4 springs both more heavily tensioned, and looser, and this same pattern was present in both.
I've had the printer for about a year and a half now. It sits by a window, I've speculated sun exposure may have caused it to warp over time but that's just conjecture.
Seems to me the only logical conclusion is that it's a physical deformation in the metal bed, is that correct or am I missing something?
Hi Guys,
I am quite new and trying to figure out why my Anycubic Vyper isn't printing crisp prints as what can be seen throughout this community.
I am currently using Polymaker Polyterra PLA with the settings mentioned below
Bed temp 60C
Nozzle temp 230C
Retraction distance 3mm
Retraction speed 40mm/s
with .4mm nozzle
if any further info is needed please let me know, i'd love to hear what you guys have to say
