I bought the flashforge foto 6 during the last closeout sale and can kinda describe my workflow with it.

Pros :
-Much, Much better detail. For miniatures it can't be beat by an FDM printer, my ender 3 isn't even close.
- Resin comes in water washable which makes cleaning a smidge less annoying. You CAN NOT just wash your prints under the tap though, set aside a Tupperware of water to clean your minis then dispose of properly according to your city's hazardous materials guidelines.

Cons :
- Cost of Filament is cheaper than cost of resin. Last time I purchased 1kg of resin it was $35-40 whereas filament is $15-20 on average for PLA. (EDIT: Thanks all for the feedback on this, turns out resin is frequently on sale these days. It's been a bit since I've purchased some!)
- Can be messy, there are ways to cut down on this, but always wear gloves and eye protection.
- Need a respirator, I use a 3M half mask reusable that takes bayonet style cartridges. A room with ventilation is a good idea.
- Resin is not really for functional prints in my experience. Just doesn't have the strength of FDM filament when all cured, it's too brittle. (EDIT: I failed to acknowledge the different resin types here, as I've only messed around with simple water-washables. forgot ABS-like resin even exists lol).

Workflow :
Import STL, add supports if not already included (kinda tricky to learn but there's a bunch of videos on resin supports). Once done, export to thumb drive. My printer settings for DETAIL on my 4K foto 6 are : Layer height .05, bottom layer count 8, exposure time 2.8, bottom exposure 35 (results probably vary for a bigger printer like this, but might be a good starting point to run your own tests).

Plug in thumb drive, print. Wear PPE, take print out of printer, scrape uncured resin into the vat, pop print into your Tupperware of cleaner. I use water and a small brush to get in all the nooks and crannies. Let it dry in front of a fan, then put it under a nail curing station that I got off Amazon for like $12. This will finish the UV cure and make it less flexible, but more brittle. Unfortunately, this is a required step.

And you're done! You truly can't beat the detail on this type of printer, but you also have to plan accordingly with PPE. There are products like the Elegoo wash and cure station that streamlines this process, but I imagine there may be some Slickdealers like me who don't want to fork over even more cash if not needed.

Overall I'm very pleased, but it's not just a plug and play hobby, you kinda gotta work at it and watch a lot of how-to's.

I have the Elegoo Mars and can speak to this from my experience. The resin is a little stressful because it's not supposed to touch your skin. From my understanding, if it gets into your skin and is then exposed to sunlight (UV) it will cure in your skin and cause irritation / rash / infection possibly (been a while since I read up on it). Not sure how easy it is to cure but didn't sound fun.

Cleaning was annoying because it didn't wash out easily (perhaps easier with ethyl alcohol which I believe is the recommended solvent, but I bought the water washable resin) and you can't just leave it in the container longer than 48 hours.

Others probably have better experiences, but just sharing mine. I've also given up on my Ended 3 Pro because every time I tried to fix it it got worse.

Any questions, I should be able to answer.

Hint for folks that buy this; FlashForge has two variations of this machine that only accept a particular file-type each. FDG and SVGX. For sake of ease the FDG version is the easier to work with. It is the one I received and just loading the USB drive that came with it, I had all the files I needed to print.

Update edit:

You can download the newest firmware here: https://www.flashforge.com/download-center/92
HUGE INFO: There are two types of boards each with their own preferred file type they will print. The Self Design board uses SVGX files and the Chitu board uses FDG. The Chitu board icons when the machine is on will be blue and black icons mean Self Design.
Download the firmware for the machine you have!

To install, and make it easy, copy or delete everything off of the USB drive they provided and then copy all the files you downloaded onto the root directory. With the Foto 8.9 turned off plug in the drive and remove the vat if you have resin inside because the update will fire off the UV light. Once everything is cleared, turn the machine on.

From here the instructions differ based on the board:
For Self Design boards, you should have an update button in the options and it will start installing all the files it can after you press update. When done the machine may or may not reboot, either way turn it off manually and then turn it back on.

For Chitu boards, go to "print" and "print" all the files on that drive. Once the .bin file is "printed", meaning installed it will you tell you on reboot it will load. You can then turn the machine off and then turn it back on.

After everything returns to normal you are good to go.

Now, you can download Chitubox for free [chitubox.com]. You will have to sign-up, I believe. The newest version has a profile built-in labeled "Flashforge Foto 8.9" you can auto load by going to the settings tab > machine tab > upper-left is a page+ icon.

All confirmed to work perfectly.

So you can't run normal STL files through a slicer and print? What's the workflow like with this unit? The price is certainly right

It comes with their own and Chitubox slicers. It indeed does import from STL. From there you save as either FDG or SVGX and see which file type your printer needs.

See updated first post.

I actually opened up the guide PDF located on the memory stick they included and followed step-by-step. They provide a Deer.stl to try in Chitu so the only error in the manual is they tell you to print the .stl file as-is.

Anyways, the manual shows how to load the included profile that is also on the memory stick into Chitu. It even specified to export Chitu files as .fdg - everything worked first time for me.


I updated the first post with more info.

Isn't resin supposed to be super messy and toxic if not handled carefully?

Hmm… 30 bucks more on Amazon.

Not sure where to buy from. It also looks like 219.99 is their regular price on Amazon.

It's more than that. The resin is a sensitizer much like latex. Repeat exposure can eventually trigger significant reactions. A little now and then isn't likely to cause problems, but people are people and many never wear gloves.

Have been using FDM printers for about 6 years and a (smaller than this) resin printer for about a year. Resin is definitely messy. Ideally, you need to wear gloves, and have a workspace that you're not afraid of getting resin on while you're transferring prints, straining resin back into bottles, etc. It's a very viscous liquid, and it will get everything no matter how hard you try, from my experience. I wouldn't set up a resin printer on anything nice, but if you have a crappy old worktop go for it. Otherwise, you'll need to use a big tray of some kind and hope you can contain the gradual and eventual mess.

However, you won't find better print quality for small and fine pieces than you will with resin printing. FDM is great for a lot of functional prints and larger format things, but resin printers are incredible for small detail things. D&D miniatures are one of the big ones people do, but you could make jewelry etc. as well. However, to get things to really pop if you want them to be translucent you need to spend a lot of time sanding - gradually using sanding paper and then Zona paper or the like. It can be time consuming.

I got my son the elegoo mars 2 for christmas, he printed a few of the sample test chess pieces and lost interest so I've been messing with it. I set it up in a spare room because it does stink up the room, and I'm using low odor water washable resin. I put an old towel down and set everything up on that, spills and mess are kind of unavoidable. I had my first few tries end up botched for various reasons, but the more I did the more mistakes I've learned from. I do not wear gloves or a mask but wash up afterwards, so far I don't feel like it's a problem.

A note on cleanup for water-washable resins (Which I can't recommend enough over standard resin) is if you keep your dirty water in a bucket or whatever you can let it cure in the sun to harden and then are usually able to throw the hardened resin away with your normal trash.
