I want to model a implant for 3D printing in STL format.

I need to adapt only part of my object (implant) to the surface and also maintain the thickness of the object at 1 mm every where. I have tried several methods and noting is working. Implant

Top picture is the basic implant designed i made.


This is the Mandible from the CBCT of the patient. In STL format.


I want the inner surface of the implant to warp or adjust in to the surface of the mandible. Also that part need to be in 1 mm thickness.

Can some one please tell me the workflow that i should follow in this case ? and get the surface well adapted to the complex geometry while maintaining the thickness.

After trying method suggested by Lemon

  • $\begingroup$ Shrinkwrap modifier can use a vertex group, so you can choose the part that will "exactly" follow the mandible surface (eventually, subdivide your mesh before doing that: subdivision modifier with "simple" option). Also can consider solidify modifier in order to obtain 1mm thickness. $\endgroup$

  • $\begingroup$ You should add that as an answer @lemon $\endgroup$ Oct 11 '19 at 15:17
  • $\begingroup$ @ArthurBlaquart I tried it and the implant looks weird on the affected region. I first apply shirinkwrap and then did the solidify and try it the other way around too. :-( $\endgroup$

  • $\begingroup$ @ArthurBlaquart i can send the both the stl file and the implant i would like to have the surface adapted. How can i send the file ? $\endgroup$
