How thin can I print?

[thirty6 3]

Trying to print a scale architectural model for a student, the problem is the supports they have designed come out at .3mm when scaled at 1:500. In cura they don't show up on the layers preview. So what is the thinnest you can print something that looks like trellis ?

You can cheat a bit and tell it your nozzle diamter is .3mm. This might be enough to get an okay print.

Otherwise consider fixing the model so that walls are .81mm thick if you can.

In my architectural experience it depends on whether the orientation of the piece on the print bed is flat or vertical.

E.G. window frames, if printed flat, I can go to 0.8mm. I could go to 0.4mm but at that size I found them very difficult to handle.

Printing vertically - I found it depends on the geometry. I printed a long straight length of "glass" for a balcony, about 4cm, at 0.4mm but again it had no rigidity and quite difficult to handle. I printed some support columns, supporting a 1st floor balcony, at 1.6mm square and printing real slow and with 4 of them on the bed to get the slowest layer time they were messy. I had to double up to 3.6mm square to get a decent result - maybe I could have gone between the two sizes but it was easy for me to double up as scale was 1:100

In my somewhat limited experience, the professionals I have dealt with, commercial or local government, tend not to go to 1:500 and would not expect great detail if they did.

So if it is flat trellis that you will mount vertically against a wall I guess you could do .4mm, but you may actually find that .8mm could be visually acceptable. I do think though that at 1:500 it is difficult to go to that level of detail
