FEA and 3D printing – challenges and potential workarounds

3D printing is challenging the ways that Finite Element Analysis (FEA) methods are traditionally employed to assess the structural adequacy of engineered components. Thanks to 3D printing technologies, it is no longer a safe assumption that materials can simply be modelled in FEA software as uniform homogeneous solids. Indeed, a 3D printed cube of material is not what it appears to be on the outside, as it can be built from the ground-up, piece by piece and may actually possess a complex internal cross section composed of intricate void spaces such as complex hexagonal honeycomb structures.

Inside the Enable Community Foundation’s (ECF) prosthetic challenge with Andreas Bastian

The Enable Community Foundation (ECF) challenges the GrabCAD community to lend a hand and take part in a challenge to create a 3D printed terminal device for those with limb differences. The ECF and the e-NABLE community believe that limb differences should never serve as barriers towards living a fulfilling and extraordinary life.

Challenge helps NASA pack for Mars

NASA’s Advanced Exploration System (AES) Division’s Logistics Reduction Project is trying to decrease the dependence on earth resupply for future long duration space missions. This is done via direct mass reduction, re-purposing logistics, and conversion of waste into useful by-products (gases, water, solids). We are trying to pack everything for Mars but our suitcase is too full. So we need to be smart about what we take, how we maximize the use of those items, and create new uses for the items once they’ve met their original purpose.
