The present disclosure provides methods and systems for printing a three-dimensional (3D) object. A method for printing a 3D object may comprise receiving a computer model of the 3D object in computer memory and generating a parametric representation of the computer model of the 3D object. Next, a first edge in a parametric representation of a curved surface of the computer model may be selected, and a 3D tool path may be generated at least in part by: (i) selecting a first set of points on the first edge; and (ii) computing coordinates of a second set of points on a second edge parallel to the first edge in the parametric representation, wherein the first edge and the second edge define the 3D tool path. Printing instructions may then be generated for printing at least a portion of the 3D object along the tool path.

Systems and methods for determining tool paths in three-dimensional printing

Methods and systems are disclosed for structurally analyzing and/or three-dimensional printing a part. The method may comprise receiving a model of the part for three-dimensional printing from a material comprising a matrix, receiving one or more properties for the material, and using the model, determining a print head tool path for use during the three-dimensional printing of the part. The method may also comprise determining a trajectory of at least one stiffness-contributing portion of the material based at least in part on the print head tool path, determining a performance of the part based at least in part on the one or more properties and the trajectory, and electronically outputting the performance of the part.

Systems and methods for structurally analyzing and printing parts

A substrate support for a substrate processing system is provided and includes a body and mesas. The mesas are distributed across and extending from and in a direction away from the body. The mesas are configured to support a substrate. Each of the mesas includes a surface area that contacts and supports the substrate. Areal density of the mesas monotonically increases as a radial distance from a center of the substrate support increases.
