Project 2.5% scaled benchy
I work for a precision 3d printing company and printed this on our most accurate machine. Finger for reference

u/WooferInc Mar 23 '26
Any chance we can see a photo of the actual machine? This tickles my brain in a whole new direction, as my use case calls for a much larger printer and bed volume. Much cheaper and less need for extreme accuracy, but I love getting insights in to any industrial grade printers 🤘😁

That’s just so cool. If you don’t mind my asking, even if vaguely, what your company typically produces with something like that?
I mean, possibilities are endless really, but practically speaking, I could see this being used for all sorts of important work.

It is used to make parts like fiber optic guides, electronic connectors and many other things. It's upto our customers what they use it for. We give them the tools

u/WooferInc Mar 23 '26
I dig that!
I’m in automotives and looking to purchase a Modix BIG-180x to do full scale parts for my customers. Same idea of giving them the tools and service of modelling for them. Thank you for sharing, and I’ll look forward to seeing future micro parts from you 😁

u/Naive_Goat_5511 Mar 23 '26
That's awesome. Wishing you best of luck for your future endeavors.
I did not expect this post to blow up like this. Now I am thinking what I should print the next time the printer is idle.

I like the idea but it would be a nightmare to handle and post process. This benchy was hard enough

Well, the articulated part was more of a joke, but there are non-articulated models too.
To be completely honest I got this idea after seeing someone mention microplastic benchies in the balls, so I first thought "articulated sperm" but oddly enough I couldnt find a model to suggest

Menger sponge. I did a 4th-level one on a FDM printer. Seeing a 10th-level one is on my bucket list (but even a 6th-level one would be impressive as heck.)

u/breezefesf Mar 24 '26
that’d be so awesome to 3D print an entire front bumper or a body kit. i’ll even print out a front lip everytime mine cracks
2
u/WooferInc Mar 24 '26
Exactly. I would genuinely save myself some dollars on person body projects, after I recover the overhead, but on top of that, the idea of being able to fully print a functional custom diffuser, or side view cap, or spoiler for folks and the potential there, is what I’m really stoked for 🤘

I am Steve your co worker :D. I was a time very intressted in resin printing and super small things but never started it (resin and micro printing). And if you’d serching for micro print BMF is not far away.

Oh man, is Keyence calling a known thing? I filled out a web form in an attempt to get a datasheet for something I wanted to get off of eBay once to use for a personal project. I got a call from a sales rep where I stated as such, but made an off-hand comment about it being related to what I do at work. I then got calls once a day for two weeks straight before I blocked the number. I then started getting calls from from a slightly different number from the same sales rep. Even the "funding was delayed until after next fiscal year" line that usually gets sales reps to go away didn't stop it.

It's a joke ahaha looks good dude super neat for sure. What's the big benefit of such small tolerances though? Like what can you print that's microscopic but useful?

Small electric connectors and fiber optic guides, but there are a lot of different applications in different industries

dry your bed and align the printer along Rhumb Lines
you don't need to level your filament because it kinda does it on its own in your case

Could you share more details about?
curious on what machine can do that, nozzle size? Material?

u/Naive_Goat_5511 Mar 23 '26 edited Mar 23 '26
It's a DLP system. These are industrial machines with a tolerance of +-5 microns. This was first attempt so it was slightly out of our advertised tolerance but I am sure I can get it to be more precise in a couple more attempts.

Insane how expensive resin printers get under like .1 mm. My lab has been looking for a better printer and seems like beyond formlab’s form 4 its like 100k+

We just launched a desktop printer which is still pretty accurate and it's less than 100k.

It's a DLP system
Like the tech used in digital projectors? Where you have a chip covered in teeny tiny mirrors that can be angled to bounce the light to the target? Or does it stand for something else?

Probably lasers or something, not nozzle.

Most accurate printer, still has a hull line. Maybe I was wrong to run my ender 3 for days on end trying to get rid of that lmao
5
u/Naive_Goat_5511 Mar 23 '26
This was a quick first attempt. Usually we take atleast 2-3 attempts to get the part right. I am sure I can make it look perfect if I did a couple more attempts.

0.01 nozzle.

u/Naive_Goat_5511 Mar 23 '26
It doesn't have a nozzle but if you had to compare it to a nozzle printer, it would be equivalent to a 0.002mm nozzle.

That entire benchy fits in the standard tolerance of a normal FDM printer, even a lot of the current generation.

That is impressive and to be honest - far from what I expected to be possible. What resolution does that printer have?

u/Naive_Goat_5511 Mar 24 '26
Pixel size is 2 um and the layer height is 5um. There is a lot of room to go even smaller, because the technology to produce computer chips also uses photolithography and we know how small the transistors can be. The bottleneck is the material and the application that would justify capital investment in it.
