Tiny Letter Stamp / possible and how to configure at best

dear community,

this is my first post and also one if the first tiny items I try to master.

I have the standard 0.4 mm nozzle installed in my i3 mk3s and like to print a tine "E" stamp with thin elements.
Any idea if this is possible or if I need to bye an 0,2 mm nozzle?

Its only 72.07 mm^2 at 100%.

I am open for any suggestions.

The printer is loaded with PLA and the flat steel sheet. 

stamp_micro.stl

Hi, this item is very small with thin sections, the 0.4mm nozzle will not work with the STL as it is,
even going down to a 0.2mm nozzle will not give a good resolution... 

In the attached .3mf file, I have used the 0.4mm nozzle and changed the XY Size compensation, which gives a much better resolution, 

changing to a 0.25mm nozzle and using XY size compensation, would also work, giving a finer background


0.4mm nozzle with 0.15mm XY Size Compensation

 

regards Joan

Dear Joan,

thank you very much for this valuable solution.

I was not able to open your attached file but could re-create the results as described by you. 

Next steps will be to mirror the letter and run a test to emboss a clay item. 

Result, surface sanded with grain 1000

Result, raw

Layers, raw

Settings & slicer view:

Small gaps in the basement layer lines, no idea why they occur. 

XY settings

to mirror the item, select it in Prusa Slicer, 
Right click, and select Mirror... along X axis... and the job is done!
