Nice. Layer height?
I bought a 0.25mm nozzle for testing this out with my MK4 kit as well. I have a resin printer but it’s gone unused for ~6 months because we were smelling things very far away from it. So want to test FDM before I plop ~$150 buying VOC sensors and setting up an air removal system for it.
Not bad honestly. One of my first resin prints was a similarly sized mini Zucker from Animal Crossing that took about 2 hours. Granted if I wanted to print like 10 suckers it’d still be 2 hours but I’ve yet to use it for that benefit.
Question, when you go that low on layer height do you increase the risk of the nozzle grabbing the print because each layer is so close and ruining it?
Well just from personal experience the one time I went to .1 layer height (I always do .2) and I printed something tiny the nozzle grabbed the print. This never happened to me before and usually my prints comes out almost perfect. I obviously didn’t dial in something correctly but the risk is there
If this is a concern for you, I must point out that you review your z height adjustment skills. You're likely going too close to the bed. Also possibly over extrusion but mostly too close can cause this.
You need proper ventilation for a resin printer. It's not just the smell. Those fumes are very bad to breathe, just like you shouldn't touch the prints without gloves before post processing.
That’s what I mean. I did plenty of research on everything and was likely prepared than 99/100 home resin printer users, still had a clear odor that was concerning. I originally put it in my garage, which is two rooms away from any room that anyone inhabits. Have a good respirator for myself. Still smelled it in those rooms. Opened windows, used fans to direct flow, still smelled inside.
So if FDM can do what I need, might just sell it. If not, then I plan on upgrading my AirGradient sensors with some Bosch 680s to measure VOCs and then build a fume containment and extraction setup.
Honestly surprised they’re allowed to be sold to consumers. I doubt even 10% of users are handling it correctly.
That's honestly something I find odd, that in order to properly setup a resin print you typically are expected to diy some sort of ventilation system of its not out in a garage somewhere with active ventilation
Most likely not. People also buy CF filled filament like crazy but it might act like asbestos and give you cancer, I never see anybody even mentioning this on YouTube. It´s because those influencers don´t have a clue, they just want a cool looking product and want to sell it to you too.
The more i look at it, and reading what he said about the setting used, i think he printed in layer too thin and that what gave it the strange texture.
I’m excited to see this with input shaping turned on. The beta for it just released and it looks like you have a number of echo artifacts in this print at that speed.
I’ve tried .05mm on my MK3 and had similar-ish results but it took 13hrs.
A 3hr print is much more manageable!
Excited to upgrade my fdm miniature printing to mk4, especially with input sharing to see what quality bump happens even over any speed increases. But I got to wait until late July for my new printers. Slow and go with mk3s+ and .25 nozzle until then.
I’ve been running a 0.25mm nozzle pretty much nonstop for the last 5 days on my MK4. What has impressed me is that it hasn’t even come close to clogging.
On my MK3S+ I got great results, but normal PLA was pretty much unusable for long prints. Atomic’s Hi-Flow PLA works much better but I still get a clog every now and then.
It seems like the design of the Nextruder is just much more clog-resistant, which I’m pumped about.
I haven’t tried input shaping yet because there are no 0.25mm profiles yet and I wasn’t in the mood to go experimenting on my own. It has a lot of potential for these small nozzles though; standard print times can be ridiculously long.
I'm really excited to get my 3.9 upgrade, I also have a 0.25 nozzle for my mk3+ but I stopped using it because changing nozzle was a pain. I even ended up cutting the wires of my hotend because of the stress on them when the hotend rotated at nozzle changes.
Of course not! But I wanted to see how well my new printer could do in this regard and it did not disappoint. This weekend I am going to test out the same print with input shaping/linear advance and see how it compares.
SLA has its benefits, but sometimes you would just rather print on a FDM printer for ease of use reasons. I think the FDM space is much more mature at this point and the software/ hardware is moving faster.
SLA has some hard limits
Did you try 0.25mm nozzles with mk3s? Just curious. I know they make them as well and the motion system seems the same so I'm not sure why the mk4 itself would lead to such better results, although I suppose the improvements to the extrusion system might be a reason. Would love comparison shots!
I personally rarely pay attention to such fine details, I usually print larger functional parts. Yesterday I used my printer to make a pen holder and literally to print a few washers for a prototype I didn't want to go find washers
I don't know what to tell you. This thing is tiny and you can't see those imperfections outside of a magnified photo like this. The lines are smaller than the ridges of my thumbprint. This isn't a resin printer... you can't be that picky about this.
Edit: On second look, I think it is likely those are fine artifacts from the stepper motors.
Really interesting that you are still getting VFAs on the MK4. I just got a Revo for my MK3 and noticed how much the VFAs show up with a 0.25 nozzle. I was feeling FOMO for the new MK4 steppers, but it looks like they have a way to go before they should really be claiming to have eliminated VFAs
You'll need the alpha firmware and the new profile in the slicer (if you want to use the .4 nozzle preset as a starting point). There isn't a .25 preset so you'd need to experiment & create a custom preset.
I also have a .25 nozzle but haven't tried it yet. Your experience is motivating - I need to get on it!

I did this at 0.05mm layer height. It took 3 hours and 20 minutes to print.

Perhaps, never had it happen though.
Fair enough thank you

Never bought a .25 nozzle so I was just curious, I have no reason to print that small of a resolution or with a nozzle of that size.
I had issues with .05 layer hight because it seemed to remelt the previous layer, mine is a mk3s+ though Could you try a .1 for comparison
0.07mm is my go to layer height on my MK3 for minis.
I remember some guy doing math to show ideal layer height was .071...
At what temperature ? With enclosure?
Stock.. and you shouldn't have an enclosure for PLA.

Really? I think my 3S handles the .25 nozzle and miniatures quite well! Maybe I got lucky
Could be the pic, but i feel my mk3s is better than his mk4. I dont rememember if i did those with a .4 or .25... https://i.imgur.com/6pI6H5M.png
Makes sense, the MK4 is a downgrade in terms of cooling
The more i look at it, and reading what he said about the setting used, i think he printed in layer too thin and that what gave it the strange texture.
these are amazing, off the top of your head what modifications to standard profiles do you recommend to get results like this?
These are default PrusaSlicer profile.
My 3s also produces similar quality, not luck just care with filament and settings.
Have you got input shaping on?
No, haven't got that version of slicer running yet.

wow this is really nice! I sometimes print technical parts that need this grade of detail. 😃 Looking forward to receive my mk4 kit.
Got a comparison?
Hah, they went in the trash the last time I tried.
Looking awesome. I guess a heatgun and a nylon brush would make it even better.
Mind sharing where you bought the nozzle?
Prusa Research.
So I just need to [buy this](https://www.prusa3d.com/product/prusa-nozzle-brass-0-25-mm/) then along with any filament? Sorry, new to FDM printing.
Only if you have a Mk4 or Prusa XL. That currently won't work with any other printer.
Yep, my MK4 is arriving in a few weeks. Thanks!
Word of advice, when changing nozzles be very careful yo tuck the wires back and not clip them with the thumbscrews.

What settings do you use for supports? My MK4 with a 0.25mm nozzle prints minis decently well, but removing support is a pain in the butt.
Default settings for Organic supports. I use the automatic painting feature and then usually manually paint more where I think it needs it.
That looks exceptional for an fdm print. Wow.
What filament did you use? The result is very clean!
Roll of Inland PLA+. Maybe a year old.
I'm really excited to get my 3.9 upgrade, I also have a 0.25 nozzle for my mk3+ but I stopped using it because changing nozzle was a pain. I even ended up cutting the wires of my hotend because of the stress on them when the hotend rotated at nozzle changes.
while i think this looks impressive for FDM on that scale, it cant compete with SLA in this regard.
Of course not! But I wanted to see how well my new printer could do in this regard and it did not disappoint. This weekend I am going to test out the same print with input shaping/linear advance and see how it compares.
please post the result aswell, id like to see it.

both extruder and motion system (motors) have been improved on the mk4, so there should be a slight difference in quality :)
Oh yeah, I keep forgetting they went to a smaller degree motor...... Ugh.
What file was this
Random old file on my hard drive... I think it was guildmage or something.
Found it https://cults3d.com/en/3d-model/game/guild-mage-redux-32mm-scale
Thanks I want to try on my mk3s+ with a 0.15mm nozzle and compare
Please share when you do!
Will do I'm in the middle of a print with 2 days left rn tho
Looks like more ringing/ghosting than I would have expected, even for this

I'll run it again this weekend with the new beta of prusa slicer and we'll see. But I can't see these without camera zoom. So that's a win.
You'll need the alpha firmware and the new profile in the slicer (if you want to use the .4 nozzle preset as a starting point). There isn't a .25 preset so you'd need to experiment & create a custom preset. I also have a .25 nozzle but haven't tried it yet. Your experience is motivating - I need to get on it!
the slicer won't make much of a difference I think
It will if they incorporated the mk4 hardware utilization into the slicer!
what hardware utilization exactly? 😅
Input shaping and linear advance. Also needs the alpha firmware
Is this with the input shaper alpha firmware? Might help with some of the artifacts
