I agree with your thoughts. I hate what Bambu has done to the industry in terms of starting a patents arms race and encouraging other companies to reject open source, but I do love how they’ve pushed innovation and have made 3D printing easier for people just looking for a tool.

I hope the DIY printers like Voron, Ratrig, VzBot, and E3NG can continue the spirit of the RepRap movement.

Cute cat! Nevermore and Bentobox are two super popular ones.

Since you’re running an E3 V2, first make sure you’ve replaced the hotend with an all-metal design. The stock hotend has the PTFE tube routed all the way into the hotend, which is fine for low temp materials like PLA, but can result in off-gassing at higher temperatures such as those used by ASA and some variants of PETG. The PTFE particles are almost certainly not good to breathe in during the long term, and can even be deadly to certain animals such as birds at small quantities.

In my experience doing a bit more than 10% can be helpful in the event of underextrusion, plus I’ve seen it add a bit more rigidity. But you’re right that there are diminishing returns till you start maxing out the infill.

4 perimeters at 0.6mm or 6 at 0.4 should be fine.

Yeah, I agree. In the photo I didn’t see an enclosure so I said PETG is fine for this application. With an enclosure you’d really want to use ABS/ASA, though PETG could work in a pinch.

I also agree that an enclosure (combined with a filter) is a good idea. I think people tend to undersell the potential dangers from 3D printing, especially for people with animals in the home.

All good, it’s still something to keep in mind (especially if OP thinks about enclosing their printer in the future). Thanks for your comment!

IMO heat formed from stress will not be a big deal, especially considering that people frequently build machines out of PETG (Prusa’s i3 variants, custom CoreXYs like Vorons and E3NG). The bigger problem is creep, which suggests that you shouldn’t use PLA for this part.

PETG will almost certainly be fine. Just use lots of walls (6 walls, maybe 30% infill). PETG’s heat resistance is more than good enough for a non-enclosed printer. Prusa has used PETG for their printer parts for a very long time without issues.

Heat isn’t the issue to worry about IMO. The bigger issue is creep/cold flowing, which is permanent deformation that results even from relatively light, sustained loads. PLA has very poor creep resistance unless annealed, but PETG is a quite a bit better. ABS/ASA would be even better but they’re much more of a headache to print.

IIRC BOTW was built on MonolithSoft’s engine (the devs behind Xenoblade) so in fairness, those games are more-so the same exception rather than the rule. That said, even without the comparison, GameFreak clearly did not properly optimize the Pokemon games on switch, with stuff like loading the whole map’s ocean at any given time.

It really depends on what you’re looking for. Are you just looking to learn how to print new materials, or do you have specific requirements for a project?

If it’s the former, I’d say the easiest thing to try is PETG. It prints pretty reasonably on most printers though has stringing issues. It has different mechanical properties that make it suitable for other applications (for example, better temperature resistance and impact strength). It’ll be much less frustrating than trying to dial in ABS for the first time.

ABS and TPU are both a pretty large step up in difficulty, but are quite good for functional parts. If you insist on learning one of these, pick whichever one fits with your projects better. For ABS you’ll want an enclosure and a well ventilated room (IMO I wouldn’t be in the same room as the printer) as it emits harmful chemicals during printing.

A filament dryer was honestly the single biggest improvement to my printer’s quality. I’d definitely recommend getting one. Wet filament is so frustrating to print.

He’s apparently said he was born in 1988. In another thread others mentioned that would make him 21 when he started his PhD, which checks out.

Not that unusual IMO, lots of people start their PhD directly after completing their Bachelor’s. If they weren’t born born in the first half of the year then they’ll have completed their BS by 21 and start the PhD either at 21 or 22.

I’ve tried Overture, Creality, and Inland (all black though, not transparent) and Overture printed the best for me (at least for functional parts where I cared about print quality and tolerances). Inland’s PETG+ and High Speed PETG was even better though.

It’s not “really” espresso but the AeroPress does make great small, strong coffees. There’s a James Hoffman video on it. You’ll want to use the inverted method (aeropress upside down, mug on top) for a short brew time, a large dose of coffee, and relatively little water.

IIRC I used 18g coffee, stir immediately after pouring 90g of water, then after 90s I flip the AeroPress + mug and press. You don’t want to use a ton of force or you’ll end up with a really bitter taste.

Sony v Connectix is the actual case that set the precedent for emulation, not Bleem. The Bleem case decided whether or not the use of screenshots of copyrighted games to advertise their emulator was legal. I believe it just deferred to the Connectix case for the legality of the emulator.

I work in an ML-adjacent field (CV) and I thought I’d add that AI and ML aren’t quite the same thing. You can have non-learning based methods that fall under the field of AI - for instance, tree search methods can be pretty effective algorithms to define an agent for relatively simple games like checkers, and they don’t require any learning whatsoever.

Normally, we say Deep Learning (the subfield of ML that relates to deep neural networks, including LLMs) is a subset of Machine Learning, which in turn is a subset of AI.

Like others have mentioned, AI is just a poorly defined term unfortunately, largely because intelligence isn’t a well defined term either. In my undergrad we defined an AI system as a programmed system that has the capacity to do tasks that are considered to require intelligence. Obviously, this definition gets flaky since not everyone agrees on what tasks would be considered to require intelligence. This also has the problem where when the field solves a problem, people (including those in the field) tend to think “well, if we could solve it, surely it couldn’t have really required intelligence” and then move the goal posts. We’ve seen that already with games like Chess and Go, as well as CV tasks like image recognition and object detection at super-human accuracy.

One of the big changes in my opinion is the addition of a “Smart Dimension” tool where the system interprets and previews the constraint that you want to apply instead of requiring you to pick the specific constraint ahead of time(almost identical to SOLIDWORKS), and the ability to add constraints such as length while drawing out shapes (like Autodesk Inventor, probably also Fusion but I haven’t used that). It makes the sketcher workflow more like other CAD programs and requires a little less manual work with constraints.

Hmm, that actually sounds like a bug. I haven’t seen that on my end (once I set the locations of options in my toolbars they stay there, even after restarts). You may want to report that on their issue tracker. Sorry that you’re having a rough experience!

Last I tried it, there was no fix. Their latest update on the website says:

The work on the toponaming problem is an ongoing project, and we are very grateful to the FreeCAD community for contributing a lot to that effort. But it’s not complete yet, there will be much more to say when it’s largely done. So let’s focus on the other three.

So I take it they haven’t implemented a fix. They previously said they were going to work with the FreeCAD team on mainlining a toponaming fix, using realthunder’s work as a proof of concept, but said fix has not landed in mainline FreeCAD yet. I believe that’s the major feature they’re looking to implement for FreeCAD 1.0.

Definitely excited for Ondsel though! Hopefully that fix can be integrated quickly.

IMO the bigger problem with FreeCAD is the topological naming problem. It’s very easy to get frustrated because your model broke due to a change you made in an earlier feature.

The UI isn’t amazing though, and that unfortunately happens quite a bit with open source software. Hopefully it’ll go the way of Blender and KiCAD with an eventual major release that overhauls the UI.
