Shape becomes rounded after using shrink wrap

After using shrink wrap mesh, I have noticed that the shape becomes too rounded. Why are the edges not preserved, and what can be done to reduce this effect/preserve the original edges and sharpness? The shape looks too distorted from the original stl model to be used, as shown in the attached images....

<?xml version="1.0" encoding="UTF-8"?> <--- the resulting mesh

<?xml version="1.0" encoding="UTF-8"?><---- the original stl model

shrink wrap is based on applying a shell mesh around an existing shape and 'shrinking' it, as if you were wrapping it with paper.

Just like when you wrap a gift for someone.

There will always be some lost in your shape.

You could use tight wrap, but if does not prevent some smoothening.

You migh need to use SimLab for reworking your STL.

It looks like you're using nTop Platform to create your original geometry, correct? I recommend using a voxel grid with a very fine voxel size to discretize the TPMS body as the meshing algorithm in nTop has difficulties discretizing complex geometries like yours. Smoothen it, then use Mesh from Voxel Grid and export it as STL. Remesh in HyperMesh to create a volume mesh afterwards. Shrink wrap mesh won't help you in this case as noted by Adriano.

Thank you so much for all your helpful responses - I will try to see how the stl can be improved /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />
