Disposable chopsticks. Seriously. You can't do everything with them (especially removing build plates and such) but when you need to fish things out of vats or cleaning solution, they save you a lot of gloves.

Oops, didn't mean to imply they were personal stories so much as just spending four years getting beaten over the head with the importance of proper safety procedures. The worst that ever happened to me personally was getting a bunch of shards embedded in my leg after an idiot blew up an overpressurized glass cylinder. I did have one professor with a severe epoxy sensitivity from constant exposure and that did not sound fun.

I'm a computer toucher and I don't use my degree at all, so the least I can do is keep this poo poo in mind when dealing with my own fun-time hobby chemicals.

edit- but my understanding of resin sensitivities is that the mechanism is similar to epoxy sensitivities, and that's really not something you want to gently caress around with. it's essentially a "when, not if" kind of thing if you're exposing your skin directly without protection.

So kind of like poison ivy then? I used to think I wasn’t allergic to it and used to pull it out by hand until one day OOPS YOU GET REACTIONS NOW.

I was just curious if you had seen or learned of any example cases. Didn’t mean it had to be you or that I doubted it. Just a lot of people say it is bad (and I believe them) but I am curious about how it manifests.

More newbie questions for you guys. Just got my resin in and I'm doing a test print now and it's looking great so that's a plus!

I got anycubits plant based resin for the low odor factor and now I'm wondering about cleaning safety. Since it's a plant based resin do I still need to treat the cleaning fluid as a hazardous waste or can I just throw the tub in front of the UV light to harden it all and filter off the bits and bin it? The article about eco resin I read baaaasically clarified it all BUT that and I don't want to go poisoning my well.

Yes, you should treat the plant based resin as hazardous but what you described is a good way to dispose of any resin. Fully cure it and toss it. It’s hazardous when uncured.

Basically treat it just like any other kind of resin.

Looking at moving, and part of that is going to be more of a dedicated 3d printer space. If I had about a grand Canad an to spend on a better FDM printer what should I be going for?

I have multiple resin printers, a souped up ender 3 in an enclosure, and a voron 0.1. I'll mostly be printing wargaming terrain to sell online

My Prusa MK3+ has become my workhorse for that stuff.


Edit: hmmm I looked up a Voron 2.4 build manual and … it looks pretty straightforward??? I built my Prusa MK3 and it wasn’t too bad. This seems about the same level of complexity with the exception of not getting pre-printed parts. Is that accurate? Having done that, I probably won’t have too much trouble, right?

If you're seriously considering it I'd recommend Tom Sanladerer's live stream build. It will take hours + hours to watch but you will see the gotchas he ran into, and it is significantly more complex to build than the MK3. He also had a custom wiring harness built for him which might be something most people have to do themselves.

Like I said, the original idea is very... basic in what I need (we're talking adaptingsomething made back in the 80's/90's at a 30mm size, so it's fairly light on fine details, to something that's about 6" tall), so I'm hoping that it'll be a good starting point for learning the program.

If you have an iPad or Mac and you aren't opposed to paying for something I use Shapr3D for things like you describe. The Free version is limited in that you don't have as many import/export options, but is otherwise open with access to all the tools. Should be able to use that for a while and see if you want to pay for it, or maybe just make 1 or 2 things. The free version only exports "low quality STLs", but that might be good enough for your use case.

New version of Lychee dropped and it's nice. Seems a hell of a lot faster on Mac and the UI has been streamlined quite a bit. Cool new features like Supports that avoid the base and model look sweet.

It also claims to have support for the Epax E10 5k, which is supposed to only use the new Chitu slicer file format. I guess I'll have to go ahead and install the upgrade so I can see if it works.

There's a terrible grinding sound when it goes down to do the first few layers. I'm almost certain this is the little flex plate tabs running into the curved side of my resin tank.

I'm friendly with a couple of the guys from 3D Resin Solutions in Illinois, who are the ones doing the manufacturing for Vulcan. I didn't get in on the beta test for that one, but I've done a lot of testing for their other resins, and if Vulcan is even half as good as the rest of the stuff they make then it should be pretty nice to use. They don't have the lowest prices in the industry but I do think they make some of the best resin you can buy (at least for my purposes). I discovered their products about two years ago and have been using them almost exclusively ever since... it was a case of becoming chummy after becoming a customer, and not the reverse, but I still don't usually mention them here because I don't ever want to sound like I'm shilling for them. except maybe this one time

Well my super cheap used Photon Mono is sort of hosed. Had a resin leak that ruined the screen and the clear piece it sits on, and since the LCD control panel has been sort of hosed up since I got it, I'm thinking I'm better off just getting a new printer. Is there a compelling reason to get anything other than another Photon Mono, assuming I don't want to spend more than $300? I have the magnetic build plate and extra vats/FEP for the Mono already, so I'm leaning that way but if there's a big upgrade I can get, I'd check it out.

Not really. Up until the Mars 3 came out, it was the only affordable 4k printer in town, and it's still a drat fine machine so I would just stick with it. Have you contacted Phrozen to see how much an LCD is?

Finally got around to getting a wash and cure station, taking the chance to re-evaluate my post print process.

I still can't find a reliable source of 95%+ IPA nor can I find Mean Green offline. Been using Everclear, is that still my best bet? I've seen acetone suggested, but don't know if that's actually a good idea or just people loving around, getting passable results, and preaching their new solution. Acetone breaks down nitrile and thus requires different gloves.

When should I remove supports? I used to print -> drip dry -> remove from build plate -> remove supports -> wash -> cure. Removing supports after curing would be a harder material, but would allow more care and closer cuts.

Acetone does work better than IPA from everything I've seen, but as you identified is more hazardous, smelly, and difficult to handle.

My workflow:

Print (I use flexi plates) > wash 1 (dirtier IPA) > Wash 2 (pretty much clean IPA) > Let dry for 30 minutes to an hour > remove supports > cure

Removing supports when the figure is still kind of soft before it dries fully has the best results in my experience. But if you remove them any time before curing you should be fine.

Textured PEI steel sheet -- is there something I should be doing every few weeks or months to 'refresh' it a bit?

I typically wipe with alcohol between prints, give it a good hot and soapy every week or so, but it's starting to lose its adhesion.

I'm thinking about lightly abrading it with the 'soft ' scotch brite in case there is a build up of filament by-products baked on.

Thoughts? Do they just get knackered over time? It is about 8 months of pretty regular use

This is what Prusa says. I haven’t had to yet, so who knows if it works.


Prints don’t stick

If your print surface is perfectly clean and all grease has been removed by wiping it with a paper towel soaked in isopropyl alcohol ~90%. Also, make sure the first layer height is set up perfectly.

If your prints still do not adhere reliably to the print surface, try to wash the sheet in warm water with a few drops of liquid dish soap (not hand soap). This can clean away oils/sugars that are not affected by rubbing alcohol. However, the textured sheet is not water-proof so consider this a last resort which should not be done often.

Looking to sell small stuff online allongside my resin stuff, but really not sure what's reasonable.

I use the exact same formula I use for resin. Essentially cost of material multiplied an aggregated factor that takes into account supplies, power, my time, etc. Then I look around to see what the market will bear and adjust accordingly if needed (I don't want to be selling double than everyone else). From what I've seen FDM can command a better price because you are printing large items in general, so people are more tolerant of it being more expensive. If anything I probably undercharge what I could but I'm certainly not losing money so... meh.

I know that lots of other mini sellers have spreadsheets where they track resin amount, cleanup time, etc for each miniature and use that in their pricing. They are completely ignoring their product -- it could be a highly detailed and dynamic model that could easily sell for $15 a pop but because of their formulas they list it for $5 and never realise the money they're losing. Just as a simple example, I sell the Godzilla model from Lord of the Print for $200 full size because it's Godzilla. A different miniature that uses similar amounts of materials and time I might sell for $80. If I just used time and materials as my cost basis like so many other sellers I'd be losing out on more than $100 from a single model. I don't know if that makes sense -- I'm finding it weirdly difficult to explain.

It would be different if they came to you with an STL and asked you to print the piece, in which case you're acting as a printing service and nothing else.

Yes, I agree wholeheartedly then! That's the part where i do research on the market for the product. If the model fits into a niche that's hard to find models for, or if there are not a lot of other sellers for it, I adjust pricing upward. :capitalism:
