Hi,
V5
choosing ‘export selected’ as .stl file, an option box appears, showing 0.01inch
I have not made any changes to such in the past and likely never used this install of Rhino V5 to do an stl, so assume its default.
If in doubt go with default, my brain says, however I know I have been drawing items finer than .01inch
this fillet was 0.00787 (.2mm) then I scale1D it using 60% and its .003inch
so I ask as its now 0.003 in one direction, did I do right to alter the option to 0.001 inch ?
what decides the value the user places in that options box ?
The item is to be mass printed 3D resin printed 50microns probably , perhaps 75 ?
standing on edge to avoid suction, or maybe tilted a tad, not enough to warrant tons of scaffolding !
Generally, that should be set to the resolution the STL printing device can achieve.
If you are modeling detail smaller than that and that is indeed the print resolution of the STL printer you’ll be using, then you are wasting your time modeling detail that fine.
Others with more STL printing experience may well chime in with their experiences.
If you click the Detailed Controls button, you’ll see that value is how far you’ll allow your mesh facets to pull away from your smooth NURBS surfaces.
generally speaking, you want your distance to surface to match your file tolerance, then use the max edge length to control how small your polygons are.
Hi,
V5
I know the printer can do 50 microns. ( 0.005mm) thats 0.000196inch in the Z axis and two can do as fine as 10 microns, though the part doesnt require that for all but the filletEdge.
I shall let the print company decide though I should be sending files suitable in the stl settings I use.
