Rapid Innovation Call

Tensile Behavior of AM Lattice Structures Project Call

America Makes is proud to announce its first Government Driven Rapid Innovation Call. Additive manufacturing of metal lattice structures presents a unique opportunity to tailor product performance and weight.  Hence, lattice structures have been considered for various automotive, medical, aerospace, energy, and defense applications.  While these complex geometric features offer another beneficial dimension of design freedom, qualification of products which incorporate these features can be financially belabored with trial and error approaches at the full component or sub-element scales due to a lack of sufficient tools and methods to assess lattice structure mechanical performance.  There exists an unaddressed need to develop and validate test coupon designs and methods which facilitate quantifying the intrinsic mechanical behavior of additively manufactured metal lattice structures.

Approaches should systematically address and eliminate sources of potential or known variation for the tensile testing of metal laser powder bed fusion lattice structures.  Proposers are encouraged to consider tensile testing of 316 stainless steel, Ti-6Al-4V, or both materials.  It is envisioned that outcomes from a successful effort will mitigate sources of variation for the measurement of lattice structure tensile properties.
