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.

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.

8gb of ram shouldn’t necessarily be an issue in and of itself, although it’s on the low end these days. The memory is also old enough that it may just be failing.

Some searching suggests you could use something like Memtest86 to run diagnostics on the memory.

If it isn’t a hardware issue, you might have luck trying a Linux distro on it. Linux generally runs better on older machines than windows, and some distros are specifically designed to be lightweight and consume as few resources as possible.

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).

Dassault too. Solidworks runs like a dumpster fire and the backwards incompatibility is a daily frustration for me. Their ham-fisted attempt to pivot to online products is so divorced from the reality of how their products get used that it’s abundantly clear no engineers were consulted when defining the new product.

The situation would be laughable if any of the alternatives weren’t also garbage in their own unique ways. Solidworks is only dominant because it’s the least shitty, not because it’s good.

How so?
