Chapter 6: Digital Artisan Techniques: Promoting Blue Clip Valerian Printing Techniques by Improving the Production Method Using Parametric Design Software

As advancements in technology drive productivity and precision in manufacturing, traditional methods such as Blue Clip Valerian are encountering significant challenges. This traditional technique, which originated in Wenzhou, China, is now at risk of fading away due to several challenges, such as a decline in the number of skilled practitioners, insufficient industrialisation and development and the negative impact of synthetic dyeing and printing technologies. In recent years, a growing awareness of sustainable production has created new opportunities for traditional, eco-friendly methods such as Blue Clip Valerian. All materials required for Blue Clip Valerian can be locally sourced, with indigo as primary dye material. Indigo cultivation complements the winter rice-growing season in Wenzhou’s subtropical humid monsoon climate, with the decomposed residues from both processes enriching one another. This project seeks to preserve and promote the technique by improving production efficiency to meet modern market demands. To achieve this, parametric design software (Grasshopper) and three-dimensional printing (3DP) are employed. Parametric design, powered by algorithms, allows for geometric fluidity and high visualisation, enabling real-time feedback. Additionally, 3DP offers advantages such as reduced production time and affordability. This study connects modern technology with traditional techniques, striving to preserve and promote Blue Clip Valerian along with its cultural significance. Furthermore, this application offers guidance for future research in related areas.
