I want to print this as a mold for a silicon part. I got the tree AA Nozzles. I'm pretty sure that if I printed with PLA .25 Nozzle an layers off .05. It will be great.

But what,if I use the same height but with a .4 or .8 nozzle. Do you think that it will give me the same detail inside.

thank you.

Since you provided the STL file I sliced at both 0.25mm Nozzle and 0.4mm Nozzle.

 

The slices are practically identical. But, the 0.4 mm Nozzle was about 0.5 hours and the 0.25 mm Nozzle was 15.25 hours.

 

Both were sliced at 0.1 mm layer height.

 

To be honest, I do not think the time difference is worth the trouble unless your need that extra precision.

 

Keep in mind that you do not have any really tight lines or details to account for. The nozzle differences are in the x and y axis only. The z axis is what will give you more layers or less layers. Top be honest, I have also noticed on even some of my curviest prints in the z axis do not really look different at the 0.1 mm layer height or 0.6 layer heights. But you do get another increase in time to consider.

 

With the x and y axis taken into account, I think you would be safe with the 0.4 mm nozzles.

 

0.4 mm nozzle:

0.25 mm Nozzle:

Hope this helps 🙂

 

Edit: You could slow down the print to increase circular accuracy. My slices were with default settings.

I would smooth out some of those sharp corners personally but this particular shape should print very well (just as well) with 0.4mm than 0.25mm.  The inner corners should be just as good with either nozzle.  Outer corners (you have none in the mold - your only outer corners are not related to the mold) will look better with 0.25mm.

 

More important - if you want this to come out high quality - is to print it slow.  I'd print this with 0.4mm nozzle, 0.1mm layers and 25mm/sec (all printing speeds - not just outer shell - because at every speed change you get a blob).

 

Also I recommend rounding all corners if possible especially deep down in the mold where walls meet floors.
