HEXR and EOS established to scale up bespoke cycling helmet output by using AR application


Protecting clothes professional HEXR, with the assistance of leading PBF manufacturer EOS, has introduced a new head scanning application allowing buyers to have a custom made biking helmet 3D printed. The “scan-to-print” system is meant as a flexible and decentralized creation technique, enabling customizability with no sacrificing merchandise safety. Extra help in the improvement of the application came from international know-how corporation Siemens and materials professional Arkema.

Fitting the dome

The HEXR fitting app operates like so: buyers around the entire world scan their have heads working with the digital camera designed into their phones (this is aided by AR and a unique cap despatched out by HEXR). These scans are uploaded by means of the app and a 3D design of the inner lining of a helmet matching the head condition is printed on an industrial-quality EOS technique. The materials utilized is a plant-centered polyamide created by Arkema. The moment printing is complete, the interior lining is dyed black and inspected one particular last time for structural integrity and end quality.

Jamie Prepare dinner, CEO at HEXR, states: “With personalized-suit intrinsic to this major-edge producing process, and outstanding impartial basic safety test scores when compared with common foam helmets, we are enabling important enhancements in helmet technologies produced doable by 3D printing certification.”

To finish up, the numerous elements of the helmet are assembled, which includes the printed internal structure, the outer shell, and the chinstraps. Buyers also have the alternative to include a little bit of excess spin on the solution with individual engravings and a wide range of shell colors. Considering the fact that the helmets are printed on-need, HEXR faces small possibility with pre-financing and overproducing, which allows the business to just focus on refining its services.

Reinventing the sustainable supply chain

The polyamide employed for the inner lining is derived completely from renewable castor oil – an place of skills for Arkema. The beans improve in significantly less than a 12 months, do not compete with other food items, and do not add to deforestation. The substance by itself has superb effects resistance and is reasonably light-weight, even extra so when printed in the clever honeycomb structure formulated by HEXR.

Dr. Karsten Heuser, Vice President of Additive Production certification at Siemens, concludes: “With the aid of our finish-to-close remedies, we developed a digital twin of an industrialized AM manufacturing unit and aided to enhance the style and streamline generation procedures – even just before production started off. By combining simulations, structure optimization, and output scenarios with a substantial degree of automation, we were being capable to forecast and lessen charge for every part considerably – enabling HEXR to scale their software into mass production.”

HEXR’s partnership with EOS actually began in 2015 when EOS begun furnishing assist in the kind of technical consulting. Final yr, the duo underwent ultimate security testing and introduced their helmets would start transport to prospects. Given that then, HEXR has managed to deliver in its further industrial partners and hopes to improve to mass manufacturing, scaling its supply chain together the way.

Just this thirty day period, EOS, together with BASF, also secured $1.37M in funding for developing 3D printed protective headgear for the ongoing NFL Helmet Obstacle. Leveraging the novel technique to protecting gear fabrication, the corporations getting section have been able to build safer solutions even though conserving on excess weight and expenditures – paving the way for a new software of the technological innovation.
