Hello, I am new to 3d printing and I am having problems slicing my file. The progress bar gets filled up and then it says 0 min to print which is obviously incorrect. I assumed the polygon count was too high so I used decimate to lower it by about 30-40% which helped cura slice it but removed so much detail that it was not helpful. The file called “smallest4layer” is the original stl file that I am trying to stack on top of itself a few times to create a filter, but I am unable to slice even the 4 layer version. The file called “smallest128layerdecimate” is the desired final product after using decimate which sliced and printed fine but was too far off from my original design. I am getting extremely frustrated with this, so any help would be greatly appreciated.

Thanks in advance

Hi

I’m not sure if your file is printable, I just sliced both files in Cura 2.4 and it took a few seconds

But then when I displayed the layers view, there was nothing to print, probably because my printer nozzle is 0.4mm

You probably need to stack the objects in Mashmixer and then convert the whole thing to solid before printing.
