7 Ways AM Boosts Sustainability

Reason 1: Reducing Waste

The first significant advantage of additive manufacturing is its approach to creation: it’s a process of building up rather than carving out, which significantly reduces material waste. Traditional methods often involve cutting away material to form a final product, which results in a significant amount of waste. The leftover powder from the Laser Powder Bed Fusion technology can often be reused.

In contrast, additive manufacturing builds products layer by layer, using only the needed material. This means less raw material usage and minimal waste production. Excess powder can often be re-used for the next project, making additive manufacturing incredibly sustainable.

Reason 2: Energy Efficiency in Additive Manufacturing

Traditional manufacturing processes, especially molding or machining, can be energy-intensive, leading to higher energy consumption. Conversely, additive manufacturing processes are inherently more energy-efficient. Compared to traditional manufacturing, additive manufacturing reduces energy usage by 25%. Additionally, in the aerospace and automotive industries, creating lightweight components through additive manufacturing significantly improves fuel consumption, ultimately lowering the environmental impact during the product’s operational phase. The beauty of additive manufacturing is not just in its precision but also in its ability to reshape our understanding of energy efficiency in manufacturing.

Reason 3: The Material World is Sustainable

Additive manufacturing is driving innovation in sustainable materials by addressing the environmental impacts associated with material production. This manufacturing method has unlocked the potential of using biodegradable and recycled materials, optimizing the use of raw materials to reduce waste and energy consumption. For instance, companies are now exploring using biodegradable thermoplastic derived from renewable resources.

Reason 4: A New Era of Efficient Design

Additive manufacturing enables a level of design freedom that was previously unimaginable. Traditional manufacturing methods come with constraints – undercuts are tricky, hollow structures can be impossible, and complex internal geometries are a fabricator’s nightmare. Understanding the additive manufacturing process chain is crucial for achieving efficient design and sustainability. By evaluating the entire process, including materials and methods, one can assess the potential benefits and drawbacks compared to traditional manufacturing techniques. With additive manufacturing, these constraints are no longer a concern. You can create structures optimized for function over form, saving material without sacrificing strength. A prime example is Siemens Energy, which utilized additive manufacturing to create a new generation of turbines. With new 3D-printed designs, they cut greenhouse gas emissions by 30%.

Reason 5: Localize On-Demand Production

Sustainable manufacturing brings the concept of local production back into the limelight. By leveraging technologies like 3D printing, businesses can produce goods on-demand, closer to the end consumer. This minimizes the need for long-distance shipping and its associated greenhouse gas emissions. Moreover, localized production creates more resilient supply chains. By reducing dependency on faraway manufacturers, businesses can weather global disruptions more efficiently, adding another layer to the sustainability of additive manufacturing.

Reason 6: Extending Product Life

Additive manufacturing offers a unique way to extend the lifespan of products. When one part fails, you can print a new part instead of replacing an entire product. This reduces waste and contributes to a circular economy, where resources are used for as long as possible. Companies across various sectors are harnessing this potential. Automotive and aerospace industries, for instance, are using additive manufacturing to produce spare parts, often enhancing their performance compared to the original parts.

Reason 7: Reducing Overproduction and Inventory Waste

Additive manufacturing naturally aligns with a lean manufacturing approach. As parts are made to order, businesses can effectively eliminate overproduction. There’s no need to manufacture large volumes of products or components upfront, reducing the need for warehousing and its associated costs and resource use. This made-to-order approach minimizes inventory waste, a common issue with traditional manufacturing, where surplus products often end up in landfills or are incinerated. By producing only what’s needed when it’s needed, additive manufacturing contributes to more efficient resource use, further underlining its sustainability credentials.

Embracing Additive Manufacturing – A Pathway to Sustainability
