What’s Next for Additive Manufacturing Materials?


Share this Article

As many additive manufacturing (AM) users and engineers know, material science is just as important as the industrial 3D printing technology itself. Both work in tandem to help manufacturers reach unprecedented prototyping and production capabilities, and without one, the other cannot succeed. AM material development and continued innovation is integral to the widespread adoption of industrial 3D printing and has many growth opportunities in its future.


As manufacturers using AM materials and those who manufacture the material itself continue to strive towards more responsible manufacturing business practices, finding ways to reduce the collective carbon footprint is a large topic of discussion. Applications using polymer materials such as Nylon 12, a material made with petroleum, are being swapped for Nylon 11, a material made from 100% renewable castor beans. Bio-based materials like Nylon 11 retain chemical and mechanical traits to Nylon 12, while also providing manufacturers a climate neutral option and a reduction in overall carbon footprint.

Manufacturers using metal materials, that produce toxic waste during production, are exploring ways to increase the recyclability of metal powders, and how to improve the vacuum ancillary equipment to not only save usable material but decrease the amount of waste produced per build. Conversations and business decisions such as these will continue to grow, as well as manufacturers examining the overall lifecycle of products to find new ways of reducing the impact of AM on the environment.

Industry applications driving material design

As new industries continue to take interest and adopt industrial 3D printing, more demand is being put on materials to provide the capabilities needed for specific, advanced applications. Industries such as drone manufacturing have brought an increased need for lightweight, strong, and electrostatic discharge (ESD) polymer materials. Industries like consumer electronics manufacturers need customized materials as well, those with the ability to be printed in fine detail resolution (FDR), while also adhering to fire-resistant (FR) and ESD requirements.

Metal materials are seeing an increasing demand for solutions with high-corrosion resistance properties. These materials need to withstand extreme chemical exposure, whether that be in a nuclear plant or laboratory, or at the bottom of the ocean within a submarine. Designing materials that can withstand these specific environments opens the door for industries that previously were limited to traditional manufacturing methods because of the materials used.

Building the AM material portfolio

Although the polymer and metal AM material portfolios are quite extensive and have continued to grow throughout the years, there is still a demand for a material portfolio that matches the traditional. For many manufacturers, they are not interested in changing the material of an application, so if that material is not available for AM, they are not going to make the switch. If AM can match the portfolios, and even exceed that of traditional manufacturing, there is a strong, competitive case for industrial 3D printing adoption.

Overall, material development will continue to be an integral part of AM success and widespread adoption. The future of AM depends equally on the innovation of technology hardware and material science and will continue to dictate the manufacturing adoption for industries across the board.
