Plastic and elastic deformation are both terms used to refer to the behavior of a material under stress (such as compression, tension, or torsion).

For an ELI5 since I don’t feel like cracking open a material science textbook or really getting more nuanced than this for a basic explanation, elastic deformation is generally reversible without permanent changes to the structure of the material, while plastic deformation imparts a permanent change.

All materials have elastic and plastic deformation modes that can be identified based on their characteristic stress-strain curve. Generally, the linear portion of the curve at lower stresses is the elastic region, and the plastic region begins where the curve becomes nonlinear.

For example, a wooden beam in a house will bend under normal load. As people move out of the room that beam is in, it will straighten back out- that is elastic deformation. Put too many people or some very heavy furniture in the room, though, and the beam will become permanently bent or even break altogether- that is a plastic deformation.

Some solid books on this topic are Shigley’s Mechanical Engineering Design and Roark’s Formulas for Stress and Strain

The colloquial use of elastic and plastic to describe certain groups of materials is based off the behaviors of these modes of deformation. E.g. elastics are stretchy and return to their original shape. If you really want to get into semantics, there are only four types of materials: metals, polymers, ceramics, and composites. Everything else is one of those 4 things.

You’re good, I didn’t take it as an attack. I totally understand where you’re coming from, I used to manage a fleet of 12 ender 3 printers with varying degrees of modifications from the previous lab manager and hated every minute of it.

I’m not familiar with Creality’s R&D program and cannot really speak to their efforts in that department. They could very well not be pursuing much R&D in addition to cutting QC and having nonexistent customer support, but I didn’t want to make claims in an area I’m uninformed.

Costs can be cut in a variety of ways and each manufacturer has different approaches that affect their end product differently. The main areas that are affected by cost-cutting measures first would typically be quality control (QC), research & development (R&D), and customer support.

In contrast to Creality, some budget manufacturers skimp on R&D instead of QC. They do this by taking existing designs developed by the open-source community (e.g. RepRap, Voron, etc.) and finding cheaper ways to produce them, rather than designing new machines in-house. For example, the Sovol SV08 is pretty obviously a Voron v2 with some custom parts to make it visually distinct.

Creality machines are inexpensive for a reason- they use cheap components and have next to no quality control. As far as I’m aware, that’s no better now than it was when they were peddling the first Ender 3s. It’s entirely possible that your friend got lucky and you didn’t in the quality lottery, it’s just the way it goes sometimes.

Older Creality designs were great if you wanted a machine to tinker with. I would never recommend that brand for people who want a printer that just works, though.

I bought a CR6-SE from Creality several years ago for similar reasons to you. It had all the upgrades one would typically do to an Ender 3 and was supposed to be basically bulletproof. I don’t think I ever got a successful print from it, and it’s been relegated to paperweight duty until I finally get around to taking it apart for components.

You’re not missing much, it’s a pretty pathetic paragraph suggesting that we should lick billionaire boots because Amazon delivery is fast.

Here’s what I got with some element zapping in ublock:

Before Amazon came along, ordering anything by mail ordinarily meant waiting six to eight weeks for delivery. Today, for a trivial fee, not only will Amazon bring virtually anything to you with astonishing alacrity, but the final cost of the goods is comparable to, sometimes even less than, the best price you can find at a retailer near your home. During the pandemic, when we were all afraid of crowds, it kept us all going with anything we needed. Thanks, Jeff Bezos.

Lmao no.

GIMP never called itself Photoshop. The problem here is this clone is using the trademarked name and lying about official association with Ho, not that it has similar functionality to Notepad++.

Also, Blender predates Maya by at least a couple years, so not sure what you’re going on about there.

Nice, the default file types isn’t a deal breaker for me. I’ll have to give it a shot! I’ve been testing debian on my laptop before changing my desktop over. Hadn’t found a good solution for a handful of my windows-only programs yet but this seems like it might do the trick.

Winboat looks really interesting. How does it compare to just using WinApps? It seems like it’s basically just doing the heavy lifting for setting programs up, yeah?

Where there a will to enshittify, there’s a way.

They could weave dependencies in such a manner as to prevent other critical stuff from running without it, or straight up build it into something that would prevent the system from running properly if you remove it.

Of course, they’d lose the vast majority of their userbase, but short term profit line must go up according to the idiots with MBAs.

Edit: fixed a typo

It’s only a layer line if it’s parallel to the bed, otherwise it’s just sparkling print artefacts.

That’s totally fair. It was not my intent to conflate people who aren’t willing/able to take on the burden of living their truth in a hostile society with people who just lack the ability to reflect on their situation, but I can see how you arrived there from my comment and I’m sorry to have put you in that position.

I realize this maybe reads like some slop-generated apology but I swear that isn’t the case, it’s just my formal writing tone!

There’s an unfortunately large amount of people who completely lack any ability to introspect or think critically

Maybe they should stop platforming these geriatric fucks and make space for the next generation then.

A calendar is not an inventory management system.

How does half a pickup truck compare to a large boulder the size of a small boulder?

Interesting. Seems like a natural next step from the recent color mixing features Bambu/Orca slicers (I assume if it isn’t already in Orca, it will be soon).

I did, but go off I guess. It’s fucking creepy to put a recording device at the dinner table, regardless of whether it’s a ‘dumb’ recording device or some bullshit slop device.

JFC. Add that to the list of brands I’m not fucking buying anymore.

THEY MAKE TOMATO SAUCE. WHY THE FUCK ARE THEY TRYING TO SELL LITERAL WIRETAPS
