New AMGTA Research Shows Environmental Benefits of 3D Material Jetting in Fashion Footwear
According to AMGTA Lifecycle Research, material jetting showed 24.8% reduction in CO2-eq emissions over traditional material processes and saved 49.9% of stock material across the supply chain
Collaborative study with Stratasys and Dyloan Bond Factory, a Pattern Group company reveals significant sustainability potential for fashion industry
Key takeaways from the study include:
· Reduction in Greenhouse Gas Emissions: The additive manufacturing print-to-textile production process showed a 24.8% reduction in CO2e emissions, when compared with traditional processes.
· Reduction in Material Usage: AM print-to-textile showed a 49.9% reduction of stock material across the supply chain, also reducing and streamlining related transportation needs, and 50.0% less material in the resulting 3D printed logo component.
· Reduction in Water Usage: The AM process showed a savings of more than 300,000 liters of water across the 16,000 logo components.
· Reduction in Power Consumption: The additive manufacturing process cut electrical energy consumption by 64%.
· Reduction in Supply Chain Dependencies: The shift to AM reduced supply chain dependencies from 4 technologies to 1: with a single additive workflow - and transportation and logistics impacts are eliminated for 3 processes.
The 14-month study analyzed the cradle-to-gate of a 3-dimensional graphic component attached to the heal of a luxury athletic shoe. The AMGTA commissioned the study in 2022 to better understand the potential environmental benefits of additive design and manufacture in an industry that may not be top-of-mind when thinking of additive practices - fashion. The study compared the manufacture of the 3D component through the traditional and additive methods, and was limited in scope to this one component and not the entire shoe. The study evaluated both processes for a production run of 16,000 logo components for 8,000 pairs of shoes and was peer reviewed by ACAM Aachen Center for Additive Manufacturing GmbH.
The traditional multiple-step process includes 2D Inkjet printing and thermal welding of injection molded parts with sheet polyurethane materials. The streamlined additive process included material jetting using photocurable liquid resins with significantly fewer steps. Additional environmental and operational efficiencies were documented related to reduced supply chain dependencies and reduced steps in the production process.
Highlights from the study can be found on the AMGTA’s website. Additional information on this study and others commissioned by the AMGTA can be found on the AMGTA website, www.AMGTA.org.
About the AMGTA
The AMGTA was launched in 2019 to better understand and promote the environmental benefits of additive manufacturing across the global economy. AMGTA members represent the entirety of the manufacturing spectrum - from design and raw materials to end products and users - focused on innovating better, more sustainable, and financially advantageous products through best additive practices.
