TPM3D: Fatigue Testing of SLS-Printed and Foamed Footwear Soles
1 min read
The Chinese company combines lattice geometry and foaming to tune footwear-sole mechanical properties.
Two design variables
Foaming modifies weight, stiffness and energy return alongside lattice geometry.
Fatigue testing
In the reported third-party test, the tested structures did not fracture after 200,000 flex cycles. This does not establish the service life of a complete shoe.
Production perspective
Powder recovery, cycle time and cost per part matter as much as lattice design in production.
