Driving Sustainability with Additive Manufacturing: A Low-Carbon Future
The global manufacturing industry stands at a crucial crossroads as the world grapples with pressing environmental challenges. With manufacturing accounting for approximately 20% of global carbon emissions [1], the imperative for sustainable practices has never been more urgent. Additive Manufacturing (AM) emerges as a transformative technology in this landscape, offering unprecedented opportunities to reduce waste, minimize carbon footprints, shorten logistical chains, and revolutionize traditional manufacturing processes.
The manufacturing sustainability challenge
Traditional manufacturing processes have long been characterized by significant material wastage, energy-intensive operations, and complex supply chains that contribute substantially to global carbon emissions. Studies indicate that conventional subtractive manufacturing methods can waste up to 90% of raw materials in certain applications [2]. Furthermore, the fragmented nature of global supply chains adds a considerable environmental burden, with transportation in manufacturing accounting for approximately 7% of global greenhouse gas emissions [3].
Additive manufacturing: A sustainable revolution
Additive Manufacturing represents a paradigm shift in sustainable production practices, offering multiple pathways to environmental stewardship:
Additive manufacturing: A sustainable revolution
Material efficiency
AM fundamentally transforms material utilization by employing a layer-by-layer approach that uses only the necessary material for production. Research demonstrates that AM can reduce material waste by up to 90% compared to traditional manufacturing methods [4]. In the aerospace industry, for instance, the "buy-to-fly" ratio (the ratio of raw material weight to final component weight) has been reduced from 20:1 to nearly 1:1 through AM implementation for some components [5].
Energy efficiency
The localized nature of AM production delivers significant energy savings throughout the manufacturing lifecycle. Our previous blog, How AI and Machine Learning Enhance Part Selection for Additive Manufacturing, highlights the role of technology in improving energy efficiency. By enabling on-demand, point-of-need manufacturing, AM reduces the energy footprint associated with transportation and warehousing. Studies indicate that localized AM production can reduce transportation-related emissions by up to 40% in certain supply chains [6].
Circular economy integration
Additionally, AM plays a pivotal role in advancing circular economy principles. The technology enables the use of recycled materials and facilitates component repairs of production tooling and end-use parts rather than complete replacements. A notable example is the automotive industry, where AM-based repair techniques have extended component lifecycles by up to 300% [7].
SelectAM's approach to sustainability
At SelectAM, we're driving the transition to sustainable manufacturing through data-driven software solutions and consulting. Our platform incorporates several key features that enhance companies’ environmental performance:
Data-driven sustainability metrics
SelectAM's platform delivers preliminary sustainability metrics through process simulation and re-design impact assessment. The system simulates material utilization, providing immediate insights into resource usage patterns per manufacturing process. Furthermore, the platform helps manufacturers and engineers with the assessment implications of redesigning and light-weighing parts, enabling manufacturers to improve their environmental performance consistently.
Environmental Impact of SelectAM's Optimization Tools
Intelligent part analysis
Our advanced algorithms accurately simulate the material usage and machine times, helping the manufacturers choose the right process and print parameters for a given component. The user can run a part orientation simulation to minimize support structure requirements, significantly reducing waste material in a build.
Charting the course to a low-carbon future
The journey toward sustainable manufacturing requires ongoing innovation and collaboration. In our previous blog Part Identification for Additive Manufacturing: A Data-Driven Approach, we explored the next steps in creating more sustainable manufacturing processes. SelectAM is advancing AM sustainability with data-driven topology optimization impact estimations to improve material efficiency. Additionally, we’re helping companies understand the best production method for a given component not only by looking at the price but also by estimating the production time and support structures needed.
