AI Technical Summary
Existing additive manufacturing components are difficult to manufacture directly to conform to standard threads, and the post-processing is complex or requires additional effort, especially in the case of difficult-to-machine materials such as nickel-based alloys or titanium. The problem of reliable connection of threaded elements has not been effectively solved.
By designing mushroom-shaped receiving spaces in additively manufactured parts, including widened molding sections and cylindrical support sections, and utilizing compression threaded elements such as blind rivet nuts or threaded sleeves, gauge-compliant threaded connections are achieved. Combining form fit and press fit, the threaded elements are secured and prevented from rotating within the part.
It enables reliable connection of standard threads in additive manufacturing parts, simplifies the manufacturing process, avoids complex post-processing steps, and improves the pull-out resistance and positioning stability of threaded components.
