Scan path generation for a rotary additive manufacturing machine

A computer-implemented method to facilitate creation of an industrial asset item via a rotary additive manufacturing process wherein a build plate rotates about a vertical axis and moves, relative to a print arm, along the vertical axis during printing, comprising:

• receiving, at a frame creation computer processor from an industrial asset item definition data store, at least one electronic record defining the industrial asset item;
• slicing, by the frame creation computer processor, the data defining the industrial asset item to create a series of two-dimensional frames helically arranged as a spiral staircase of steps, wherein a hatch angle associated with a frame of one revolution of the build plate and defined between a centerline of the frame and a scan line is different than the hatch angle associated with a frame of another revolution of the build plate, and wherein the hatch angle is incremented within frames of a single revolution of the build frame;
• and
• outputting the sliced data indicative of the series of two-dimensional frames to be communicated to a rotary three-dimensional printer.

A non-transitory, computer-readable medium storing instructions that, when executed by a computer processor, cause the computer processor to perform a method to facilitate creation of an industrial asset item via a rotary additive manufacturing process wherein a build plate rotates about a vertical axis and moves, relative to a print arm, along the vertical axis during printing, the method comprising:

• receiving, at a frame creation computer processor from an industrial asset item definition data store, at least one electronic record defining the industrial asset item;
• slicing, by the frame creation computer processor, the data defining the industrial asset item to create a series of two-dimensional frames helically arranged as a spiral staircase of steps, wherein a hatch angle associated with a frame of one revolution of the build plate and defined between a centerline of the frame and a scan line is different than the hatch angle associated with a frame of another revolution of the build plate, and wherein the hatch angle is incremented within frames of a single revolution of the build frame;
• and
• outputting the sliced data indicative of the series of two-dimensional frames to be communicated to a rotary three-dimensional printer.
