METHOD FOR MANUFACTURING THREE-DIMENSIONAL SHAPED OBJECT AND THREE-DIMENSIONAL SHAPING DEVICE
Provided is a method for manufacturing a three-dimensional shaped object of shaping a three-dimensional shaped object by discharging a shaping material from a discharge unit provided in a three-dimensional shaping device to laminate a plurality of layers according to shaping data for shaping the three-dimensional shaped object layer by layer. The shaping data is generated based on shape data indicating a shape of the three-dimensional shaped object. The method for manufacturing a three-dimensional shaped object includes: a first lamination step of laminating an n-th layer, n being any integer of 2 or more; a measurement step of measuring a physical quantity of an (n−1)-th layer; a data processing step of preparing shaping data for an (n+1)-th or more layer; and a second lamination step of laminating the (n+1)-th or more layer according to the shaping data prepared in the data processing step. The data processing step includes executing a correction step of preparing the shaping data for the (n+1)-th or more layer by correcting shaping data generated in advance based on the physical quantity, or a generation step of generating the shaping data for the (n+1)-th or more layer based on the physical quantity and the shape data.

System and method for improved infilling of part interiors in objects formed by additive manufacturing systems
A slicer in a material drop ejecting three-dimensional (3D) object printer identifies the positions and local densities for a plurality of infill lines within a perimeter to be formed within a layer of an object to be formed by the printer. The local density of each infill line is filtered and a control law is applied to the filtered local density to identify an error in the local density compared to a target density. This process is performed iteratively until the error is within a predetermined tolerance range about the target local density. The error is used to generate machine ready instructions to operate the 3D object printer to achieve the target density for the infill lines.
