Formlabs uses a proprietary resin cartridge... it's the paper printers situation all over again, the printers themselves are not that expensive but the disposable ink costs an arm and a leg.
Don't go with Formlabs, support any of the open-platform alternatives.
And also, be aware that these printers require some serious development work (you need solvent to wash away uncured resin (if you ask me, this basically necessitates a chemical hood... Formlabs will happily upsell the "Form Wash" for this for another 699). If uncured resin falls on your floor (which has happened to me a little too many times), boy is it a horror cleaning it up even if you have industrial grade solvents; FDM printers are easier and their "ink" is much, much less expensive by comparison.

It says it includes "Open Material Mode" which let's you "...print with any 405 nm photopolymer resin or 1064 nm powder on Formlabs 3D printers..."

The amount of upselling, extra parts necessary for basic functionality, predatory resin pricing and specific open "modes" that are free to be subjects to amendment by contract makes this seem like a cash grab for investors rather than serious product. Really sour taste in the mouth from this.
Just buy an open source version from China that has the necessary hardware in an open format and let Claude adjust the software if there are concerns.

I'm unclear what the open source version from China of a resin printer is. Creatlity and Elegoo don't appear to be at all it as they lock you to the chitubox ecosystem.

What are the open-platform alternatives? I was under the impression that the majority of printers used the CHITUBOX hardware platform internally, which was now locked to the CHITUBOX slicer. Has this changed? That would be wonderful news.
I don't think that Formlabs locks you into their wash and cure stations. Some of their printers lock you into their resin, but it looks like the Form Studio 1 discussed above and the Form 3, 3L, 4, and 4L let you use resin of your choice, although the Studio 1 does require you to buy a special $80 tray.

This printer at least comes with the "Open Material Mode (included)" that lets you print with 3rd party resins. I'm sure the workflow won't be quite as nice as with the Formlabs native resin. That is unless you can somehow refill the old jugs or buy empty ones. Before long I imagine 3rd party compatible containers will show up.

If you’ve ever used resin printers, you know the cartridges are a good thing because the liquid inside is basically carcinogenic if it comes in contact with your skin, so a lot of people just don’t do resin printing for exactly that reason and this gets around that.

Except you will have failed prints (for me it's 1 out of every 10 with my form 4), which will require taking out the tank to clean obstructions and free-floating debris... and when you're having to filter the resin (like so: https://www.youtube.com/shorts/UdX94R3k7YU ), it's exceedingly hard to not get it in contact with your skin.

This page really needs to explain what is “resin printer” and why would I need it. I have no idea how is it different from my regular 3D printer.
dofm 7 minutes ago [-]
Your regular printer, like mine, presumably puts down a line of melted plastic material with an extruder, bit by bit, so the print time is guided by complexity as well as size.
Resin printers, basically:
- dip a plate (upside down) into a thin tray of resin
- push it all the way onto onto a screen at the bottom of the tray
- blast that screen with UV through a translucent LCD display that contains a mask image of the current "slice" of the whole plate
- lift the plate out of the resin so it peels off the screen and the resin replenishes below it
- repeat, with the next slice.
- then the whole model is taken out by hand, blasted with UV light to completely cure it, washed off and the (more or less inevitable) supports snipped off.
So instead of printing line by line, the entire plate prints layer by layer — a small print takes (approximately) the same time as a full plate.
There are several big differences, notably that it is single-colour, much higher resolution, the various peel/adhesion forces are managed differently, the parts need to be hollow so uncured resin drains out, most resin prints are quite brittle, and the whole process is traditionally really rather cytotoxic.
There are eco resins, tough resins, and printers that do a better job of not being chemically evil; this is one.
I've stayed away from it, because it's not the kind of printing I need (for all except one part that I might end up subcontracting) and because it is chemically nastier than b/w darkroom printing, which until now has been about my limit of risk.

It prints by curing a resin instead of heating and forming plastic. They've been around in industry for decades.

The commenter you're replying to doesn't represent the company and they are 100% correct. The company is known for selling expensive products to educated commercial customers. A five second Google search for "what is a resin 3D printer" gives you a very good idea of what's being talked about here. Clarifying every single obvious details in the comments doesn't improve the conversation being had here.

I used to use an older, more expensive version from FormLabs in my last company to print our (more accurate) version of Invisalign negatives, and we'd thermoform the aligners over the top of the cured resin (with a barrier).
The accuracy was great. They'd hold up. Printing took a while, but generally pretty solid as we scaled from in-house to full lab setup. They're great as resin printers go.

I have a noob "reverse" resin creation question. The product page says it has low VOC emissions. Could certain recyclables(e.g. 4,5 HDPE types) create the resin from my stuff at home with low VoC that I could use/sell etc?
My gut would say economically/technologically prohibitive but a low throughput table top recycler seems like a great way to reduce my recyclable garbage.

there are products where you can re-melt and create filament for 3d printers or push it into a mold. Can probably build your own for $500 + a $500 3d printer.

Please, please do NOT buy a resin printer as your first printer; IF you want to print intricate details (where resin excels) at least start with an FDM printer anda 0.2mm nozzle. Lots of information can be found here at r/fdmminiatures.
Resin is extremely toxic and requires a dedicated area and handling and care.
twelfthnight 35 minutes ago [-]
My first printer was resin without a dedicated wash/cure set up and it was difficult enough that I sold the printer and got an FDM. Currently I'm using an Snapmaker U1 and it's really awesome and much easier. It also prints in multicolor seamlessly.
That said, if you do spend the extra for this along with the wash/cure and the voc extractor, the demos are really impressive. It seems like this printer is blazing fast, for single color prints it will print basically anything at better resolution than an FDM in <2 hours, whereas FDM could take anywhere from 4-12+ for a similar part with bigger layer lines.
virtualritz 37 minutes ago [-]
You can wash the print in an ultrasonic bath [1] in isopropyl alcohol (IPA).
Then cure using a UV LED strip (5m w USB plug ~2 EUR) inside an empty can (another 2-5 EUR) and a solar-powered rotating base [2].
The light from the LEDs is cures as well as powers the base. All four will set you back less than 50 EUR.
You can wash manually with some isopropyl alcohol in a wash basin and then cure in the sun. It will be a pain to do, and somewhat inconsistent, but its possible. You can also get a cheaper wash and cure station for other 3D printers that would likely work well enough with some tuning.
pedalpete 43 minutes ago [-]
We don't have a wash here at our office, we just use a small container with IPA.

Ive been 3D printing for over a decade, SLA printers are just not worth it IMO. There useful for certain applications, especially industry but for home hobbyist, FDM + 0.2mm nozzle would go further as a first 3D printer

Agreed, unless you need to print intricate 3D figurines or high resolution engineering widgets, get a FDM printer and avoid the mess of SLA.

Wrote this elsewhere, but this printer prints a full volume in 2 hours. In many scenarios it's 10x faster than FDM with better resolution and compatibility with advanced materials, like food grade / skin contact, ultra strength and rubber-like consistency.
You actually would probably want the wash/cure and VOC extractor upgrades so it's more like 1200$ before it's useful, but if you have the clean room space and ability to handle the toxic resin, functionally resin printing is typically better than fdm for single color prints.

From the hobbyist perspective, the main thing this gets you is much more precise and detailed prints, so they're very popular in the model making community.
From a professional perspective, this gives you access to a bunch of different materials that open up all kinds of options for prototyping.
SchemaLoad 19 minutes ago [-]
The slight increase in fine detail is just not worth the toxicity imo. Put a 0.2mm nozzle on your FDM printer and you'll get good enough quality. Leave resin to businesses that can set up a proper warehouse with fume extraction and PPE.
You can even prototype your designs at home with FDM and send the final file to a company to do the resin prints.
hingler36 5 minutes ago [-]
I agree that for most people it's not worth it, but for people who need it it's absolutely necessary. The biggest hurdle is making sure new hobbyists don't just assume it's like FDM with minimal post-processing.

As someone who got into FDM printing about a year ago, and still finds it very exciting, this is a really compelling resin printer. It's priced very well for the capabilities, especially in terms of providing everything a beginner might need to be comfortable with resin printing.
That said, I just noticed Costco online has some FDM stuff, which I think is a pretty exciting development, so if I have any money to spend on 3d printing stuff in the near future, I'll probably spend it there. :)
