The   3d   FDM   printing   process   starts   with   slicing   an   stl   (Stereolithography)   file   into “curves”   of   the   desired   height   and   adding   toolpaths   for   the   printer   to   follow. The   slicing can   cause   errors   as   the   stl   file   is   only   an   approximation   of   the   part   geometery   using triangles.   Creating   tool   paths   using   a   “one   size   fits   all”   approach   will   cause   air   gaps reducing the strength of the part. At   Eee   Tee   Digital   Design   we   slice   the   stl   file   and   edit   every   curve   to   repair   the   errors. Next, we generate a generic toolpath and edit every curve to reduce or eliminate the  air gaps.
