The Art4leg prosthesis cover is shaped into the form of a natural human leg. 3D scanning is used for customization by taking accurate 3D scans of the user’s healthy leg. The personalized surface of the cover expresses the lifestyle of the individual for whom it has been designed. The cover is 3D printed from durable plastic. It is attached to the leg prosthesis by using high-powered magnets that hold the front and back panels tightly together. The style and functionality of the cover gives the prosthetic device a new dimension and improves self-confidence of an amputee using the cover.

Tomas Vacek studied Industrial Design at the Tomas Bata University in Zlin. In 2011, he and his brother Jiri founded Studio Vacek, which specializes in product design. His designs have been displayed in some of the most famous exhibitions in Paris, London, Milan, and New York. He is the chief designer of Art4Leg since 2015, when Art4Leg has been launched together with 3Dees: Centre for 3D printing in Prague.

A startup specialized in the design and production of customized 3D printed prosthetic leg covers. The concept behind Art4Leg is to create a fully customized and stylish cover for each user. No two covers will ever be the same. The process starts by taking accurate 3D scans of the user's healthy leg. Secondly, the user chooses a design that they want to apply to the cover, either from a set of designs in the Art4Leg collection or their own unique creation. Thirdly, the cover is engineered to precisely fit the user's prosthesis so that it does not interfere with any of the mechanical parts. The end result is a fully customized cover that is modeled on the user's natural leg, with an applied design that suits their personality and precisely fits their prosthetic device. The covers are produced using industrial quality 3D printed thermoplastics. Without this technology it would be technically complex and prohibitively expensive to produce a unique cover for each user.
