Shock Absorbing Structures For Sports Helmet [WIP]

Sports Protective Equipment Fabricated With Additive Manufacturing

Project: Design and test of shock-absorbing structures produced by AM to be applied to helmets used as PPE (Personal Protective Equipment) in sports as climbing, biking, skating, etc.

Innovation: Use of an impact-absorbing structure designed specifically for AM production.

Challenge: We believe that an inner structure of a safety helmet designed with a shock-absorbing lattice structure and produced by AM would make a better helmet.

Application: The solution PPE helmet can be used in outdoors sports as climbing or biking or skating..

Activities:

Design study on several techniques to generate lattice structures.

Fabrication of test probes produced in MJF PA11 and SLS TPU

Dynamic Impact Tests

Test consisted in dropping 5 kg round metal object onto the test subject from a height of 1m. Test was run at the User Partner lab, equipped with testing machinery, using the 1011e 1012_MAU 1002_2W ALU_SF equipment by CKL engineering (figure 3 left). Machine measures the total impact force which is absorbed by the sample, measured in Newtons.
