Additive manufacturing impacts sustainability, innovation
Additive manufacturing (AM) is being utilized to drive the future of sustainable technology forward and encouraging innovation. Six indirect impacts and two direct impacts are highlighted.
Additive Manufacturing Insights
- Additive manufacturing (AM) is advancing its energy efficiency efforts and technology. By directly and indirectly affecting carbon emissions, AM is mitigating costs for companies and contributing to climate change efforts.
- Companies like EOS have started exploring new design variants for AM technologies. It is expected other industries will follow closely behind the AM industry by using inductor principles to reduce costs and consumption.
Additive manufacturing sustainability can be very complex. More organizations are starting to put a “green label” on products in hopes of minimizing their waste and costs, but one question remains: How sustainable is additive manufacturing?
Additive manufacturing’s impact is being discovered in real-time, and the manufacturing industry is continuing to see growth when it comes to energy efficiency and technology advancement.
Value chain and product lifecycle of additive manufacturing
Fabian Alefeld, senior manager of Additive Minds Consulting at EOS, said companies need to consider the whole value chain and product lifecycle to truly understand the impact in his presentation “Additive Manufacturing as a Driver of Sustainable Business Models and Applications,” at IMTS 2022 in Chicago.
The value chain consists of raw material, grinding and automatization, additive manufacturing, post processing and ends with the final part and lifecycle. “From my perspective, the final part and lifecycle is the most important and most impactful [part of the value chain],” Alefeld said.
Collecting and analyzing data from the value chain process is essential to fully understand the impact. According to Alefeld, “If you don’t collect data on the process and on the application, you’re driving half blind.”
Six indirect and two direct impacts of additive manufacturing
Additive manufacturing can both directly and indirectly affect carbon emissions.
“Indirect impacts are really the interesting ones,” said Alefeld. “They can be more sustainable, and also more cost-effective.” Indirect impacts are typically more far reaching. The root of additive manufacturing and prototyping is faster technology development, which is an indirect impact on sustainability within these applications.
Indirect impacts from additive manufacturing include:
New business models
Faster technology development
New applications and technologies
More efficient applications
More efficient supply chains.
Direct impacts of additive manufacturing affect the environment and overt sustainability goals.
Direct impacts include:
AM processes emit less CO2 compared to conventional manufacturing
AM process chain produces less waste than conventional manufacturing.
The future of additive manufacturing
Top emissions per industry vary, with electricity and heat leading at 31%, followed by the manufacturing and construction industry contributing to 12.4% of energy emissions. Energy contributes the most emissions overall at 72%.
AM enables technologies that would not be possible with conventional manufacturing alone, including a new type of inductor.
Traditional inductors have posed challenges to manufacturers by having unpredictable service lives due to manual labor discrepancies, performance issues, long lead times and shape limitations. Conventional inductors also are mostly made of copper, which is difficult to put all energy into and more difficult to manufacture in general. By utilizing purpose-driven design and customization, AM eases some challenges for manufacturers.
Design variants for new inductors include strong asymmetrical geometries, shapes that can’t be rolled and better cooling through walls and pins. This leads to performance improvements that affect the cooling channels, contour accuracy, material savings and load optimization.
Purpose driven has helped reduce manufacturing costs, eliminate edge overheating and create more flexible soldering points that have contributed to up to 30% reduction in energy consumption and higher reactive power capabilities.
Adefeld’s company, EOS, has integrated a step into these designs with their dual function inductor. The dual function inductor has less power consumption and needs up to 60% less energy. It has also increased the lifespan by 2.5 times.
Adefeld expects the transfer of inductor principles will be applied to other industries. “This is really just the beginning.”

Additive Manufacturing FAQ
What are examples of additive manufacturing?
Additive manufacturing, also known as 3D printing, is a process that creates three-dimensional objects by building up layers of material. There are several different types of additive manufacturing techniques, each with their own advantages and disadvantages.
Which materials are commonly used in additive manufacturing?
A wide variety of materials can be used in additive manufacturing, depending on the specific technology and application. Some common materials used in additive manufacturing include plastics, resins, metals, ceramics and composites. While these are among the most common used in additive manufacturing, researchers are often experimenting and developing new materials.
Are additive manufacturing and 3D printing the same?
Additive manufacturing and 3D printing are often used interchangeably, but they are not exactly the same thing. 3D printing refers specifically to the process of creating a three-dimensional object by building up layers of material. It is a subset of additive manufacturing, which is a broader term that encompasses any process that creates an object by adding material to it, layer by layer. In other words, 3D printing is a specific type of additive manufacturing.
Is it expensive to 3D print?
The cost of 3D printing can vary widely depending on a number of factors, including the type of printer, the material used and the size and complexity of the object being printed.
For industrial production, the cost is significantly higher than it is for hobbyists or small scale production operations. Some industrial 3D printers cost hundreds of thousands of dollars. These printers can be used to produce large-scale, complex parts and have higher production speeds.
The cost of materials used in 3D printing also varies widely depending on the type of material used. For example, plastics are normally cheaper than metals. Overall, 3D printing can be expensive, but it can also offer significant cost savings.
