7. BioFabricating Materials¶
Research¶
Research¶
This project was heavily influenced by the knowledge and hands-on techniques I gained during Fab Academy, particularly during the module focused on bioplastics and biofabrication. I wanted to explore a method of creating leather from fish skin, utilizing fish byproducts sourced from local seafood production. This approach not only makes use of otherwise discarded materials but also supports the development of sustainable alternatives to traditional leather, which is often resource-intensive and environmentally harmful.
References and Inspiration¶
My primary inspiration came from that week’s class discussions, where we explored innovative, low-impact materials. The focus on combining natural processes with modern techniques led me to experiment with simultaneously tanning and dyeing the fish skin—a time-saving method that could also yield unique aesthetic results. I was particularly interested in merging traditional leather-making practices with modern eco-friendly techniques to create materials that are both functional and sustainable.
Process and Workflow¶
notes
Step 1: Preparing the Tanning and Dyeing Solution¶
To simplify the workflow and reduce chemical waste, I created a combined tanning and dyeing solution. The mixture consisted of:
- 200 ml of glycerin (a natural softening agent)
- 200 ml of spiritus fortis (96% ethanol) for preservation and tanning
- Natural dyes from Rawnice, added directly into the solution for simultaneous coloration
This method allowed the fish skin to tan and absorb color at the same time, streamlining the process and giving the leather a rich, even hue. Using plant-based, food-safe dyes ensured that the final product stayed within a sustainable and environmentally conscious framework.
Step 2: Tanning the Fish Skin¶
Once the solution was ready, I immersed the cleaned and prepared fish skin into the container, making sure it was fully submerged. To ensure even distribution of the tanning agents and dye, I agitated the container every two hours, gently shaking it to allow the liquid to reach all surfaces of the skin.
The fish skin remained in the solution for several hours to days (depending on thickness and texture), allowing the mixture to penetrate deeply and soften the fibers while coloring the material. This process not only conditioned the skin but also imparted a unique, vibrant finish through natural dyes.
Reflection¶
This experiment in biofabrication represents a meaningful intersection of sustainability, tradition, and innovation. By using a readily available waste material—fish skin—and transforming it into a durable, colorful leather substitute, the project highlights how local resources can be repurposed into high-value, eco-friendly materials.
Combining the tanning and dyeing steps proved to be efficient and effective, reducing labor, time, and chemical use. The use of natural dyes offered a visually rich result without sacrificing sustainability.
Most importantly, this project demonstrated that biofabricated materials can offer practical and scalable alternatives for applications in fashion, costume design, and product prototyping, while minimizing environmental impact. The process opens the door for further experimentation with textures, colors, and material behavior, making it an exciting step toward a more circular approach to material design.
