Three-dimensional ribs and method of three-dimensional printing of ribs for crash test dummy
First Claim
Patent Images
1. A method of making a three-dimensional rib for a crash test dummy, the method comprising the steps of:
- providing a three-dimensional printer;
making a CAD model of the rib for the crash test dummy, wherein the model of the rib forms a first rectangular cross section comprising a damping layer sandwiched between two band layers, the first rectangular cross section extends along an axis perpendicular to the first rectangular cross section to form an arcuate length terminated at opposing ends, and each of the opposing ends forms a second rectangular cross section comprising a unitary band layer without a damping layer that extends away from the adjoined first rectangular cross section damping layer along the axis; and
printing, by the three-dimensional printer, the CAD model using a band material to form the band layers and a damping material to form the damping layer.

Abstract
A three-dimensional rib for a crash test dummy includes at least two layers of a band material and a layer of damping material sandwiched in between the at least two layers of the band material.

10. A system for making a three-dimensional rib for a crash test dummy, the system comprising:
-
a three-dimensional printer; and a controller coupled to the three-dimensional printer and configured to; generate a CAD model of the rib for the crash test dummy, wherein the model of the rib forms a first rectangular cross section comprising a damping layer sandwiched between two band layers, the first rectangular cross section extends along an axis perpendicular to the first rectangular cross section to form an arcuate length terminated at opposing ends, and each of the opposing ends forms a second rectangular cross section comprising a unitary band layer without a damping layer that extends away from the adjoined first rectangular cross section damping layer along the axis; and print, via the three-dimensional printer, the CAD model using a band material to form the band layers and a damping material to form the damping layer. - View Dependent Claims (11, 12, 13, 14, 15)
