DIY-Materials

The image captures a researcher engaged in an experiment transforming organic waste, specifically pea pods, into new sustainable bio-materials. The workbench features a mix of household and scientific tools: a pot for extraction, purple silicone molds, circular bio-plastic samples with vegetable inclusions, and a notebook filled with technical notes. The scene illustrates the methodological research process: manipulating raw natural materials to develop innovative, low-impact environmental solutions.

Materials are unquestionably one of the main players in the design process. It is through materials and associated technologies that the future of the artefact and its relationship with users and the environment are determined. The principle behind the development of materials following the Do It Yourself Materials (DIY-Materials) approach emerged within the concept of the Materials Experience, which describes a holistic view of materials in design that allows us to understand and define how a material can influence thought, feeling and action.

DIY-Materials are defined as an emerging material experience and are created through individual or collective self-production experiences, often with techniques and processes of the designers own invention, as a result of a process of "Material Tinkering", i.e. through creative experimentation with substances, ingredients and processes. These may be new materials, created by adding other elements, or they may be modified or further developed versions of existing materials.

The photograph documents the physical results of a material experimentation project at Politecnico di Milano, focused on bio-design. In the foreground, a booklet showcases the "Laboratorio Concept Design" and the "Material Driven Design" process, surrounded by various prototypes: brown hemispheres with a fibrous texture resembling mycelium or pressed organic waste, thin sheets of flexible bio-matter, and colorful samples (red and blue) exploring different textures and densities. To the right, a fan-shaped set of technical cards lists the properties of the developed materials, highlighting a scientific and design-oriented approach to sustainable innovation.

The cross-disciplinary research group DIY-Materials was founded and is still led by Valentina Rognoli, Associate Professor at the Department of Design of the Politecnico di Milano, with the participation of Italian and international researchers.

The photograph documents a series of samples exploring the chromatic transition achieved through natural pigments. At the top are arranged seven wads of raw fibers, likely wool or cotton, ordered in a smooth color gradation: it begins with an unbleached white on the left, moves to a vibrant yellow, then a golden mustard, a pinkish beige, a light pink, and finally a deep burnt Sienna brown. Beneath each raw fiber wad is a corresponding small square of dyed fabric, demonstrating how the same dye translates onto a finished surface. The clean and methodical arrangement highlights a scientific and experimental approach to creating eco-sustainable colors and understanding their behavior across different textures and compositions.

It is easy to determine the origin of traditional materials - it is certain that plastic comes from oil and glass from silica - while the origins of DIY materials are not so obvious. Their classification is based mainly on the origin of the material or the materials of which they are composed, and is inspired by the taxonomy of Linnaeus, the Swedish botanist, zoologist and physician who in 1758 collected the elements of the earth in his Systema Naturae.
Therefore, in order to facilitate the classification and understanding of DIY-Materials, five groups have been defined, referred to as kingdoms. From the more traditional and easily imaginable Kingdom Vegetalia, Kingdom Animalia and Kingdom Lapideum to the more complex and less obvious Kingdom Recuperavit and Kingdom Mutantis, referring respectively to materials born from waste and those
materials born from the evolution and mutation of ingredients, even from different sources, through the use of a specific technology.
Following this scheme, a database *www.diymaterials.it * has been developed, presenting several case studies and some materials created within the research group by individual designers or by groups. This database is intended to be an archive of inspiration for future research around the topic of self-produced materials.

The collage features fourteen polygonal panels showing detailed close-ups of various raw materials of animal origin. Included are a honeycomb with a working bee, a dark texture of glossy bubbles resembling caviar or amphibian skin, and a series of samples exploring the chromatic and textural transition of hides and furs: from a vibrant yellow and a golden mustard to a pinkish beige, a light pink, and a deep burnt Sienna brown. Beneath each raw fiber wad is a corresponding small square of dyed fabric, demonstrating how the same dye translates onto a finished surface. A central red band displays the white text "kingdom animale" in sans-serif characters, while a stylized icon of a tanned hide appears on the right. The clean and methodical arrangement highlights a scientific and experimental approach to creating eco-sustainable colors and understanding their behavior across different textures and compositions.

In addition to the DIY-Materials activities, the research group focuses, both theoretically and practically, on cross-disciplinary topics related to materials for design, circular and sustainable materials, connected materials and interactive systems. In addition to consolidating its research themes with funded research and projects, the DIY-Materials research group intends to intensify its actions in the area of bio-fabrication, the manufacture of materials and artefacts using living organisms such as algae, mycelium and bacteria, through doctoral research, projects and cooperation at the international and national level.
