Hi

Silly question, but I'm playing with dual material printing with my 3D printer, and hen I save the SharkCAD Pro model, I get default facets or triangulations, that can be seen in the 3D print model, and the print.
This is a snapshot of the "Automaker" slicer software representing the parent material (blue) and the support material (orange), and the actual 3D print in "normal" mode.

Has anybody else experimented with the default STL export settings to reduce this "facetting" or triangulation with their 3D printer.

Many thanks
Mike

Right-click on your (native nurbs) model in VC and select change object type, choose mesh. The dialogue panel opens as shown, the mesh parameters change the .stl facet resolution. Cancel the change type instruction so that your model remains fully editable and associated, keep it selected and export the selection only as .stl, the .stl will retain the facet resolution that you've specified. If you've saved your model as .stl without retaining the native VC nurbs original, you've lost the capacity to do this and it'll have to be rebuilt to recover it.

Thanks for that murray,

Last night after posting the question, I did just change the STL Mesh Parameters Normal Deviation from the default 8.0 to 2.0, and I got a similar effect to your image.
I will try your method, but just a FYI, I already see improved aka finer "facetting" on the 3D print model.

Hi,
Adjusting the parameters is a bit tricky.
I always do small and accurate parts in HD sla.
Here are my usual parameters...
