or microspheres may also be associated with the usage of this invention as substantial components for applying the proposed unified fibrous tissue regeneration for disc replacement once the intervertebral scaffolding image design dataset is created it can be automatically converted into a surface representation in stl file format stereolithography triangular facet data this makes it possible to fabricate the intervertebral scaffolding from any type of solid free form fabrication sff system using either direct or indirect methods the direct sff methods include but are not limited to 1 selective laser sintering sls 2 stereolithography sla 3 fused deposition modeling fdm and 4 selective laser melting slm one example solid freeform fabrication method may be found in u s patent application publication no 2003 0074096 which is incorporated herein by reference as if fully set forth herein indirect methods are based on casting biomaterials such as those listed above into a mold created on a sff system in addition to the above sff systems the molds may also be created on direct 3d printing systems including those systems that print wax the indirect methods described in u s patent application publication no 2003 0006534 and u s pat no 7 087 200 which are both incorporated herein by reference as if fully set forth herein may be used to make the disc scaffold the methodology of the invention has been implemented to make scaffolds for temporomandibular joint repair in a yucatan minipig model the design procedure.
