Abstract: 3-D build jobs having surrogate supports, 3-D printers using surrogate supports, and techniques to support vulnerable regions of build pieces using surrogate supports are disclosed. The surrogate supports are generated in a first material configuration and are offset via a gap from the vulnerable regions. The gap comprises a second material configuration, such as loose or partially fused powder on which the build piece can be supported during 3-D printing. In alternative embodiments, the gap instead includes thin manual ties or a solid body using material that is stronger but more amenable to breaking off without damaging the build piece. Post-processing steps are dramatically reduced as the surrogate supports and gaps facilitate virtually error-free separation from the build piece. In an embodiment, the surrogate supports include a support structure extending to a fixed base underneath, the fixed base being a build plate or a global surrogate.

Abstract: Self-supporting 3-D printed chassis structures are disclosed. Self-supporting ribs are selectively printed to walls of the structure to meet desired dynamic stiffness targets while maintaining a reduced mass. The self-supporting ribs can be used as both support structures (e.g., for outer walls) during 3-D printing and as stiffening structures when the chassis structure is in operation. In an embodiment, the chassis structure is printed such that no support structures are needed. Topology optimization can enable remaining unneeded internal ribs or supports to be removed, and a high inner spatial volume between ribs can be maintained to make maximum use of the part. In various embodiments, wall thicknesses can be maintained at or below 1-2 millimeters, which further reduces mass.

Abstract: Techniques for joining nodes and subcomponents are presented herein. An apparatus in accordance with an aspect of the present disclosure comprises a 3-D printed first part having an interconnect co-printed with the first part such that the interconnect of the first part can float within the first part, and a 3-D printed second part having an interconnect co-printed with the second part such that the interconnect of the second part can float within the second part, wherein the interconnects of the first and second parts are configured to form a connection between the first and second parts.
