Zieta Prozessdesign is a multidisciplinary team of architects, designers, engineers and technologists. We cooperate with psychologists, biologists, scientists and many others specialists in order to create the most innovative solutions. These solutions are FiDU and 3+ technologies of stabilising metal sheets.

As process designers we not only aspire to design fabulous forms. our aim is to create innovative solutions which generate endless possibilities for development and usage. We design processes that are inspiring and lead us to unpredictable results and forms.

Through out design process we want to reach the best possible synergy between technology and design. Thanks to this that we are also a manufacturer we can bring the whole process to perfection and all projects are produces in EU.

By changing and deforming sheet-metal into structural elements, we discover a whole new world of ultra-light, stable and durable construction. We fully utilise its potential and qualities of the material with our process of ‘controlled loss of control’. We design a net of points which define the final form, but the space in-between is defined by the material itself creating the bionic, unique and one-of-a-kind form of our objects. Sheet-metal is not just steel, but also ultra-light aluminium or copper which we use for our limited edition collection.

FiDU Technology
FiDU is an innovative method of changing bits to atoms. Today’s world is overflowing with unnecessary and intrusive data. We puts emphasis in its production processes not just on using less material, but also less data.

Zieta Prozessdesign uses precise robots and organised tools to create an effective and sustainable production process. Thanks to the programmed process and excellent understanding of the material, sheet-metal, the designer can pass on some of their competencies.

With FiDU technology designers can only control key joining points of the geometry, while surfaces and the negative space were the result of free deformation by internal - ‘controlled loss of control’.

Thus the material ‘decides’ about its final form which is achieved when deforming from 2.5D (two welded flat metal shapes) into 3D using internal pressure. Production files required to define the 2.5D form are just a few kilobytes when allowing for a ‘controlled loss of control’. Trying to define the same final form for traditional production methods would require several gigabytes of data!

FiDU technology is also mass customisation. Its the continuation of craftsmanship, in which the material nad craftsman leave their mark in the object they create, giving them their individual feel. That’s what FiDU achieves – unique products on a mass scale.

Moreover – it makes objects so durable, that it can be categorized as an ultra-light construction. It allows us to create innovative, customised, bionic shapes and to produce them in small series using very efficient production processes. The technology can be applied to produce ultra-light constructions of great weight capacity – for product design and architectural elements.

About 3+ Technology
Create your own design with components made in the technology of 3 + is so easy and unrestricted as building with Lego or Mechano constructions.

The office, workshop, kitchen, lounge room and retail are all stationary, yet characterised by mobile function. They tend to follow the contemporary user.

3+ technology reinvents its function every day with every interaction. It becomes an ultra-light construction for the every day, thanks to its strong, innovative and minimalistic features, which you create.

In our collection we offer chairs, tables, shelving, but we don’t want to categorise them as office or dining chairs, workshop or kitchen tables, because it is you, that creates their function. Thanks to a simple system of connectors and versatile elements you are able to give each product a new context, function or even create new ones from scratch. Each perforation is a starting point to satisfy your personal needs, accommodating products to new situations and tasks.

3+ is work, hobby and leisure. It is customisation, lifestyle, space – it’s always current, and ready to answer the requirements of change.

First researches led by Oskar Zieta, Philipp Dohmen and professor Ludger Hovestadt started at the ETH Zurich in 2002 by the in-depth analysis of the properties of the metal sheets. The purpose was to find an efficient and customized way to stabilize the thin material using a computer controlled production chain and to build durable construction elements using it. The first experiments were made of bent steel sheets that formed 3d structures able to carry their own weight. From 2002 a series of objects, roofs, ceilings, paravents were created and the know-how is now being used for many projects.

The experiments on the FiDU technology began in 2003. FiDU can be compared to IHU technology of hydroforming used in a car industry, but is far less expensive, because no moulds are needed. Short series of unique objects can be made that way. FiDU requires one thousandth of the pressure needed for IHU. The main advantage is that the production is very fast, flexible and precise. Two dimensional elements are cut from the steel sheets and welded one to another using laser and then the inflation transforms them into a stable 3 dimensional object.

FiDU football - a modular object, a more than 4m diameter icosahedron, i.e. a football, explored the application of such characteristics as planned contour control, precision and rigidity. In this case, high precision was required. 90 elements in total were produced. This project was the first successful completion of a refined, precise, three-dimensional construction from FiDU elements. This is where one often overlooked feature of the basic technology is brought to the fore - FiDU is a sophisticated combination of digital and laser production techniques tailored to produce the highest possible accuracy in forming technology, in which the level of precision loss is taken into account deliberately.

As further development of the research on the FiDU technology, the following task was produce a non-symmetrical profile for a wind rotor. Three aerodynamic profiles were created and successfully tested for a low-cost wind turbine. This project has manifold benefits over traditional wind turbine construction and bionic design (assymetrical profiles are inspired by whales’ fins). In addition to significantly lower production cost it is also possible to scale the blades to almost any size and thus adapt the design to the specific weather conditions of any location.

One of the most important projects to date, the FiDU-foot bridge, was carried out in late 2007 with architecture students from the ETH. The foot bridge has a span of 6m and a net weight of only 174 kilograms. The span to weight ratio astonished even the enlisted ETH structural engineers. The expected 500 kg were easily supported during a professional stress test, and a top weight of 1850kg exceeded all expectations giving the FiDU bridge a 1:10 weight to load-bearing ratio. Thus, FiDU was positioned as a new player in the ultralight construction class. The main ingredients of the construction were there still: 1mm thick sheet metal and 0.4bar from the air compressor.The technology is suddenly as mobile as a simple air compressor.

The series of rolled steel profiles - "Blow and Roll", were created for the London Design Festival 2010. The new opportunity is the milestone in the development of FiDU. Flat and rolled elements can be transported cost-efficiently on site an then inflated and unrolled to the stable form.

Thanks to volumetric expansion allowed by FiDU technology, we are able to create antennas’ constructions made of steel that take a marginal room on board but can be inflated through the inside pressure deformation in space and reach very large dimensions. In this way we get ultra light steel antenna constructions that are produced in effective and flexible production process.

In 2007 another technique was invented as a development of the technology of puncturing the metal sheets. Metal sheets are punctured and then they can be put together and joined by the holes. Connecting 2 metal sheets using this technique makes a stable, usable object. In 2007 Oskar Zieta has created two experimental chairs in 3+ Platte technique. They are made of thin steel sheets, laid one on another and joined by the punctures. The technique can be used as a construction for furniture and facades.

Our latest product HOT PIN explore subject of inner thermal deformation. The classic PIN hanger is created by seam welding two sheets of metal and deforming it through inner air pressure using a compressor. The HOT PIN is similar but is formed through pressure formed within the object itself. The user receives the product flat packed and sealed with special potion locked inside. At temperature of 200ºC the HOT PIN transforms from a flat 2 dimensional object gaining a bulbous 3 dimensional shape. This way we can „bake” many objects made of metal sheets.

Production process
Through out design process we want to reach the best possible synergy between technology and design. Thanks to this that we are also a manufacturer we can bring the whole process to perfection and all projects are produces in EU.
Our production process takes advantage of synergy between technology and material properties. Excellent knowledge of material and our technology have a crucial influence on efficiency, flexibility and environmental aspects of the process. Most important for us are not only machines, but connections between every part of every machine and process. We use additive production method. It means that we created 3D object by inflated flat shapes without taking away any material. Due to FiDU technology we can create customized construction elements with a variety diameters.
Our objects are made of steel and are fully recyclable. It means that they can be reused again and again as a fully valuable material which helps save resources and avoids waste.

Furthermore, processing of sheet-metal in FiDU helps reduce CO2 emissions due to lowered material use. We develop techniques for transporting our pieces more efficiently. We learn to fold and roll them and transport them flat-packed, to save space in transportation and in storage. We develop lighter versions of our products made of thinner sheets and ultra-light materials any time that great load bearing is not needed.
We use efficient packaging without colour prints or complicated graphics. Boxes used for our products are made out of 100% recyclable cardboard that can be further reused.
