Quick question, I am planning on doing some prints with my ender 3v2 with some glow in the dark rainbow filament. Should I invest in more brass nozzles or upgrade my nozzle in advance for the abrasive nature of the filament? Any suggestions on what type to use?

If you're printing abrasive filament, you should not be using brass. The nozzle diameter will not be 0.4mm by the time you're done with a reasonably sized print (ie, the size you'd need in order to show off that fancy rainbow). This will make your print fail if it's severe enough, taking your expensive rainbow glow in the dark filament with it. Hardened steel like the ones you linked is what I'd use for that type of filament. I can't speak for quality of those specific ones however.

Both options work, but running through a little GITD won't murder a new brass nozzle immediately if you want to experiment before upgrading.

But I grabbed a bunch of cheap ones for spares too to see For what it's worth, I haven't had a nozzle get seriously clogged (like something that a cold pull won't fix) since like 2015. Hell, even clogging at all is extremely rare with regular plastics. Better hotend designs these days mean that the nozzles usually just work. I have had a few brass ones wear their bore into an oval from thousands of hours of printing, and a lot get gross looking while still working fine, and that's it. Buy one good E3D brass nozzle, or spring for a hardened one if you're planning to do abrasive filaments, and just forget about nozzles for the next couple of years.

All3dp gives the impression that both are good for that type of basic use, but I'd appreciate commentary on how it handles, spares worth having on hand, and quality of life upgrades worth getting from the goon hive mind. Nothing heard but I went with the Mega zero 2. Anycubic's online store has them on sale for $145 though, which seems like a good deal if you're not in a hurry.

InternetJunky posted:Except for FEP changes every 3 months I don't do any preventative maintenance on my machines. That said, I also have three Mars2 Pros out of commission right now waiting for new screens so maybe I need to adopt some type of general cleaning routine. I'm not sure that would solve anything though as FEP holes are the screen killers and they are pretty much impossible to prevent unless you strain your resin after every print and replace your FEP after each failed print. I guess I've been lucky since I've been running the printer pretty heavily for more than 3 months and there doesn't seem to be any indication right now that the FEP is in imminent need of replacement. I do have a roll of replacement film ready to go just in case. I'm thinking I'm lucky because I haven't really had any failed prints (one, kind of, out of easily 50+ full build plates), so there haven't been any floaters running around in the vat to puncture the FEP. You're probably right that I should start scraping down the whole build plate after each print instead of just relying on dumb luck, though.

Hello Braintrust. I need help. Odor, and potentially chemistry help. Running a resin printer. In a basement. The smell starts.. to get serious. And my buddy with the printer, is concerned for the health of people in the household. There's two questions: First, is about how to manage things. How do you deal with resin printer smells? Are you concerned about them? The thoughts that come to mind are, in order, ventilating the enclosure to the outside. Building a warmed box to run the printer in a garage. Finally, a heavy duty carbon filter in an enclosure inside. In a rather involved conversation Friday, we got into the toxicity of resin. We know that the resin itself, is toxic. But what about the materials that do vaporize from an open bath of resin. What is the component that's evaporating? Is that component toxic? Resin is toxic... Have I missed the rash of long term effects of dealing with resin?

I feel like that still amounts to a few hundred bucks, with resin and the rest of the assembly line and other startup costs included, so it's not THAT cheap. Still *pretty* cheap.

Enders, and I mean all enders, print out of the box. My sample size is reasonable. (about 12?) This puts creality a good step ahead of a lot of the smaller vendors. They ~work~. The biggest problem I have with complaints on 3d printers, is that they aren't ~a printer~. At least, how we think of printers. They're CNC machines. And to our benifit, they come as COMPLETE CNC machines. If you've ever priced out machine tools, you'll find that the vast majority of them come with a hilariously inept set of basic parts, and frequently, are plain ~not functional~ if you buy just the machine. poverty goat posted:You'll never convince me that creality is cool and good for continuing to ship printers with useless warped beds after the problems came to light. If nerds had held them to account like literally any tool or computer supplier would be for shipping defective equipment maybe they'd have had reason to get their poo poo together. Warped beds work. But your logic doesn't work here... And there's a cost to what you're saying. The cost, is ~literal~ cost. The cost for a cast aluminum bed for my ender was $45. The whole printer was $200. Practical terms, this would have made me not get into this end of CNC. The bed alone for my V0 is $30. The bed for my Legacy? $60. If you want "something better" the scale is there. There's printers at the consumer level, for every dollar range from $100 through $2000 or so. Creality is a business. As (especially) Chinese businesses go, they're pretty decent on most levels. poverty goat posted:Sorry to anyone I berated earlier, the printer and I had a bad morning and spooky, inexplicably things were happening with that thing that stopped me from really even testing the extruder I'd just torn down and put back together. I might have been naive getting into this but the plan when I impulse bought the mystery box was always to avail myself of the amazon return policy if I couldn't get anything out of it, and I think it's headed right where it belongs. quote:I learned a lot from my Ender 3 v2 and put that to work ordering an Anycubic i3 Mega S for 199 based on recurring themes in reviews that it works out of the box, doesn't need any extra parts to perform really well and is well supported by the company I'm still not sold on the e3v2. I don't like the screen. And coming with a glass bed was how they deal with people eating the magnetic sheet. If I were them, I'd be shipping it with a garolite bed, instead of glass. But I think the choice of glass is driven by "the community" instead of what's best. *shrugs* The big selling point of it is that it has the silent driver board. Everything else about it.. doesn't make me happier about the machine. That said... I've moved up in the world. You're here late. (to the party, that is) And I'm sorry. What you're going to find, especially anywhere BUT here. Is that the 3d printing community, in general, doesn't know it's rear end from a hole in the ground. I could write a LOT about that. It's really frustrating. I've left most f the groups I've been in about 3d printing because of how entrenched bad advice is. And lovely people are. Voron is an exception to this. As is VoidStarLabs.

It's styrene you can probably smell, and we already know styrene to be bad for long term health. TL;DR if you can smell it, it's giving off something. Even if you can't smell it, it may well be giving off something.

But, you can trick the printer into shutting itself off, with a switch on.. say.. the Z axis that'll flip a power switch at max height. All you'd need to do, is add a line of code that sends the Z up, and boom, it's off. I've seen it done with bed movement too. ----------------------------------- On the subject of "if you can smell it, it's a problem". Well... that's a bit of a trick for me. I can smell PLA, PETG, no matter what. From ~rooms away~. My nose twitches at the end of my driveway when someone is running the dryer with a dryer sheet in it. I'll smell the orange that's just started to go moldy from the front door, when nobody else can smell it. My nose is notoriously sensitive, so "if you can smell it" is rarely a good measure for me. It's nice on some levels, it sucks on others. It means I need to know what an odor is. And I can then know if I can do my best to ignore it, or if it's a danger.

If the print is finished, show her where the power switch is and she can turn it off. if the print isn't finished, then either move it or install quiet fans. With good ones, it should be pretty close to silent. PS: Putting people on ignore is weak. :P

It's darkly amusing to me how wide the range is in terms of how people treat resin printer safety. You've got everything from people running these printers all day on their desks two feet from their face to people who won't run them anywhere except in a detached structure with a full fume hood and scrubber. There's also very little authoritative or reliable information. Even with a background in chemistry and tons of research into the topic I'm not at all confident in my own choices or making suggestions for other people. Resin printing is cool as hell, but extremely disconcerting in some ways.

It's also worth pointing out that the Elegoo data sheet you linked is in direct contradiction to your post here: An MSDS is, however, a head's up document that you should take precautions. They are also all written from the perspective of the reader being properly trained in basic safety precautions when handling or working with industrial chemicals and substances. If you're going to look at Elegoo's MSDS compared to the others and say "Welp, it's safe to go without basic PPE!" then you shouldn't be advising anybody about anything to do with resin printing, you're correct about that in your previous post. Also, since you missed it: and Now, what happens to resin materials when resin machines are printing? What's that? They are warmed by the UV reaction and/or warmed by the user for easier printing? Oh wait, "good industrial hygiene practice" can't possibly mean making sure to wear proper PPE if you find yourself encountering industrial fumes from an industrial process, can it? Yeah, the sheet doesn't specifically say "if you smell fumes during use, you should probably put on some PPE (or set things up so that you ventilate the fumes away from the area you are in)" but that opening statement about avoiding breathing the dust/fumes from the substance isn't exactly rocket science in terms of the thought process for how to avoid it. I know home hobbyists like to play fast and loose with safety precautions vs. how things would work if you were exposed to these things throughout a work shift at a company (assuming it isn't run by cartoonishly evil people), but resin printing has been around since the 1970s and every industrial setup you may encounter about it will have specific respiratory PPE recommendations.
