  • Patent number: 10071524
    Abstract: A printing method for printing a multi-material 3D model comprises the following steps: perform a slicing process on a multi-material 3D object to generate the multi-material object slices and the object slices of a useful object; compute a material-switching point and a retrieving point during the slicing process; print the multi-material object slices of a multi-material 3D model with one of the materials; when print to the material-switching point, switch to another different material and print useful objects with the material used before the material switching; when print to the retrieving point, print the multi-material object slices with the material used after the material switching; and repeat the above steps until completing the multi-material 3D model printing. The present disclosed example prints the useful object via the remaining materials after the material switching which effectively reduces the cost with of multi-materials printing.

  • Patent number: 10065374
    Abstract: A printing slicing method for 3D model for automatically adding a required supporting structure to a 3D model is disclosed. The method includes following steps. Retrieve a minimum overlapping ratio corresponding to a layer height. Execute a slicing process and analyze an overlapping ratio between two molded object slices which form a suspended slope. Add the supporting structure below the corresponding suspended slope when determining that the overlapping ratio is less than the minimum overlap ratio. This disclosed example can effectively prevent the suspended part of a printed 3D model entity from a deformation because of the adhesion area thereon is too small, and can also effectively save the printing time and the usage amount of supplies.
