NASA’s space suits have not been custom made for
astronauts since the Apollo era due to high
costs of production

Suits are instead modified after the fact and adjusted
via inserts and other methods to reach astronauts

computational design to automatically produce an Extra
Vehicular Activities or EVA Boot
By optimizing production for FDM printing of TPU, on long term manned mission such as Artemis, Astronauts can "remanufacture" their EVA Boots or inserts
Algorithm built in Rhino + Grasshopper
To achieve a pressure supporting customizable
shape a modified Hilbert curve was used.
At higher levels it’s possible to treat 1st and 2nd level curves as replaceable cells while keeping the links constant seen blow with smoothed curves
Base this cell replacement on a plantar pressure map and it becomes possible to selectively densify the infill pattern
Offset the curve, loft through the surfaces, and repeat to create a spring like surface from which a final shape can be cut out
This method enables high printability in FDM printed flexible materials and allows custom pressure distribution for 3D printing of recyclable materials
