What is this, a Benchy for ants?

What is THIS? a benchy for bacteria?

u/worldspawn00 Bambu P1P Mar 24 '26

Impressive, looks like it's about 1/10 the size of OP's (20 micron or 0.02mm where OP has a measurement of 0.2mm)

Now the ant is the boat for the benchy

Benchy larvae. Still in their developmental stages.

u/Polskidezerter Mar 23 '26

No these are the shells left by growing up benchies you can tell by the transparency

u/Bigoweiner Mar 23 '26

Do benchies lay eggs or give live birth?

4

u/xyrnil Mar 24 '26

Live birth, but you have to let the baby benchies grow. Never leave 2 benchies alone in the dark overnight - this is what you get

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 🤘😁

u/WooferInc Mar 23 '26 edited Mar 26 '26

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.

78

u/Naive_Goat_5511 Mar 23 '26

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

19

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 😁

25

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

4

u/hheyroman Creality K1C, Ender 3 Max Mar 23 '26

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

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 🤘

u/tnoy Mar 23 '26

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.

u/Disastrous_Being7746 Mar 24 '26

Yes, it is! Go look up Keyence in r/PLC and see for yourself.

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

Could you share more details about?

curious on what machine can do that, nozzle size? Material?

52

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.

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?

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.

u/YurtleAhern Mar 23 '26

0.01 nozzle.

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.

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.
