Model　slicing　is　a　key　process　in　3D　printing　technology　from　digital　model　to　entity.　Traditional　slicing　technology　takes　a　long　time　to　slice　massive　model　files.　Using　distributed　computing　technology　and　cloud　platform　technology,　distributed　model　slicing　can　be　realized　to　improve　processing　efficiency.　In　this　paper,　we　propose　a　distributed　3D　printing　slice　cloud　platform　based　on　cloud　computing,　which　combines　model　layout　algorithm　to　segment　massive　model　printing　tasks.　In　this　paper,　25　models　are　used　to　carry　out　the　distributed　slicing　experiment.　The　maximum　acceleration　ratio　is　2.25.　The　results　show　that　the　problem　of　too　long　slicing　time　in　3D　printing　production　can　be　effectively　solved　by　using　distributed　computing　technology　combined　with　model　layout　algorithm.
