Thin Parts Are Very Flimsy and Don't Hold Shape

Support & Troubleshooting
1

Good morning,

I have been trying to print a small object to help automate microscopy experiments in my lab. We are hoping to print something that will allow us to compartmentalize a microscope slide. This is 2 mm thick.

We are printing this file on a Form 3 using V4 Clear resin. I have tried printing this file flat on the plate, and it failed. I’m using a layer thickness of 0.5 mm and the default orientation, auto-supports. I’ve also used my own supports as well. Both times this came out to flimsy to use effectively. Each compartment is separated by a 2 mm by 2 mm by 50 mm rod. These seem too thin to keep properly rigid when printed.

So, I am here wondering if I should change resin, settings, supports, etc. Please see the file in question and thanks for reading!

It will be very hard to print correctly the thin ribs.
As I print a lot of thin shells here is one orientation of the model which may help you to get correctly all other things except the ribs.

BTW, if I have to make such part I would do it on my milling machine instead on the 3D printer,

Thanks for the response, I’m going to try thickening the part and see how it goes.
