HP 3D-prints glasses for dyslexic children

French company Atol Opticians has revealed how it was able to use HP’s 3D print technology to manufacture special glasses for dyslexic children in the country.

The frame for the glasses weighs just 35 grams

Abeve, a start-up business created by Atol Opticians, used a HP Multi Jet Fusion 3D printer to produce the new Lexilens glasses, which make reading easier for dyslexic children.

The electronic Lexilens glasses have active and tinted lenses that filter out the mirror images that cause reading difficulties. Children can activate the lenses by pressing a button on the glasses, triggering the electronic system incorporated in the temples.

Working with Erpro, a specialist in the mass production of 3D printed products in France, Abeve used the HP Multi Jet Fusion to 3D-print the frame for the glasses.

The manufacturing process for Lexilens 3D printed glasses is remarkable as it is the first printed multi-component product with such a complex assembly

“Atol Opticians is committed to delivering visual wellness for everyone and at all stages of their lives,” Atol chief executive Eric Plat says, adding: “3D printing has reduced manufacturing lead times for Lexilens, enabling us to commit ourselves to dyslexic children as early as possible and help them unlock their full potential for improved educational and social inclusion.”

Emilio Juárez, EMEA sales director for the HP 3D Multi Jet Fusion business, also praised the innovation behind the project, saying: “The manufacturing process for Lexilens 3D printed glasses is remarkable as it is the first printed multi-component product with such a complex assembly.

“As there are no less than nine components, our partner Erpro’s expertise was extremely important in the context of developing multi-component products, where assembly groups must be managed without compromising the quality of the final product.”
