Ultralightness for generations to come

Zieta Studio presents a story of interdisciplinarity—art, bionics, and technology—that results in unique objects that provoke the senses. Using the proprietary FiDU method of forming steel, we create functional objects that suggest their functions through their captivating shapes. Come see how our commitment to the process leads in its own directions, and be inspired by our pursuit of innovation.

We create functional objects whose potential is maximized through a bottom-up approach. The foundation is fascination with the material. The next step is stabilization and moulding. The final effects are objects whose form is the result of a partnership between the design team and the freedom of the material. The leading area of exploration is steel, but the FiDU proprietary technology is also applied to other metals, such as aluminium and copper.

The essence of design is fuelled by its parametric dimension. We automate processes and use new generative technologies to maximize material and human potential. The works result from years of study of the properties of metal, using the proprietary FiDU method of forming steel with internal pressure to create sculptural objects that provoke the senses. The shapes only suggest their functions.

Studies in ultralightness

Steel is an incredibly strong and versatile material, but it can also be prone to buckling under load. Addressing this issue by studying the material properties over the years, Oskar Zięta as an engineer has looked to the natural world for inspiration. One example is the development of metal products that mimic the structure of bone.

The tale of ultralightness is the continuous optimization of the lightweight index, meaning the ratio of an object’s weight to its strength. Harnessing the potential of algorithms, FiDU technology and optimization of the lightweight index allows for creation of light and durable steel structures, both big sculptures and functional objects.

Less is less—we mean it

ULTRALEGGERA, the world’s lightest metal chair, is the best example of this research, today expanded to the ULTRALEGGERA family of objects ideal for both indoors and outdoors. The studies in ultralightness dive into two major narratives: accessibility and ease of use for old and young, as well as the reduction in material consumption.

For generations to come

Most of Zieta Studio’s objects today are “circular” products: monomaterial, sustainable and fully recyclable. They did not become this way in the era of popularization of concepts such as the circular economy and the UN Sustainable Development Goals, but were conceived that way from the dawn of the search for production optimization. Zieta Studio is guided by the minimalism of form and material intensity starting at the conceptual level.

Ultralightness also manifests itself in the virtual dimension. Designing flat objects that take a 3D form only in the tactile world brilliantly reduces data consumption. Using the PLOPP object as an example, its standard 2.5D model consumes 16 kB of memory, while an identical design developed in a 3D model would need as much as 142 GB. Zieta’s less-is-less approach thus maximizes the material potential for design, daily functionality, and reduced transportation costs.
