I have an object that has very precise teeth that need to fit with matching teeth on a second object and they occurs on top & bottom of each object. I have tried various orientations with limited success. I have also split the object in half to have a flat base on one side. I have tried then printing the object with this flat base attached directly to build platform. This did give me a flat base but with voids and the teeth were very precise. Whenever I print with supports the attachments always create imperfections and in some cases warpage that does not give me the precision I need. I am thinking of trying printing with the teeth adhered directly to the build platform but this would mean having some portions of the model unsupported for a small distance. Does anyone know how large and area can be unsupported before distortion starts to occur? Also does anyone have experience printing directly on the build platform without have these voids occur , what causes the voids to occur and is there anything one can do to the model to not have the voids occur? Thanks in advance for any help or advice.
