slicer resolution of slice itself #17043

Is your feature request related to a problem?

I want to request higher resolution for the slice itself for us who prints super small prints on FDM with 0.1-0.2 nozzles

This is top of the head of a 10mm tall pikachu with 0.1mm nozzle, and the resolution here is less than pretty. So i want to request a feature to double/quadruple the slice's resolution so that with microstepping, we can achieve super high resolution quality miniatures.

Increased slicer gcode commands per millimeter.

The resolution of any model is mostly dependent on the resolution that the model was created with. Programs like MS3D Builder will allow you to "Simplify" a model to decrease the resolution but you cannot increase a model's resolution beyond what the original translation software converted that model into. The Cura setting "Maximum Resolution" can affect the resolution that shows up in the gcode. Smaller numbers mean more short line segments will remain unfiltered and be part of the toolpath. That reaches a point of diminishing returns as the printer is flooded with line segments in the range of nanometers. These are two exports of the same model. The one on the right is a High Resolution export and doesn't show any faceting. image

The slices make it looks like the low res model is smoother, but it is highly faceted. image

And this is what the slicer sees. There are no curves in either model. Just approximations of curves as the triangles that make up the mesh get smaller. image
