Gone are the days when 3D printing was primarily associated with a singular class of materials—mainly low-cost thermoplastics—which limited potential use cases. Today, an expanding palette of new materials is delivering greater choice and flexibility, driving more widespread of adoption of 3D printing and opening doors to new applications across an array of non-traditional industries.

IDTechEx is now forecasting that the global market for 3D printing materials will hit $29.5 billion in 2032, broadening out to include new polymers, metals, waxes, sands, even concrete materials that are classified as higher-performing. New metal-matrix composites, recycled plastics, and bio-ceramics are hitting the market, allowing enterprises to move beyond simple prototyping to producing higher quality products along with the ability to test drive concepts with materials that accurately mimic the final product’s appearance and behavior, IDTechEx officials said.

Here's IDTechEx’s take on what’s happening in the key 3D printing materials segments:

Polymers. Polymers have long been the public face of AM materials and are still most in demand, yet they are changing. Most engineers are familiar with low-cost filaments like PLA and PETG, yet that familiarity limits the perception that 3D printing is only suitable for basic prototyping applications. With the advent of more functional and higher-performance polymers now available—for example, fiber-reinforced polymer matrix composites—enterprises can benefit from additional strength and stiffness benefits for more sophisticated applications. High-temperature thermoplastics, foams, recycled plastics, and bio-based polymers are also gaining steam.

Metals. While powders have been the dominant feedstock, metal 3D printer OEMs are starting to consider alternative materials to support the delivery of lower-cost printer models that are also easier to operate while ensuring high-quality prints. Lower-cost metal wire and metal injection molding pellets are gaining traction. Another option is metal paste, which is viewed by some as a safer alternative to powder, which has handling concerns and can be highly combustible. The IDTechEx report doesn’t see these new feedstocks replacing metal powders as the dominant source; however, analysts there believe the introduction of new materials sources will only serve to expand the metals 3D printing market.

In addition to new materials advances, the advent of multiscale material modeling and simulation is also helping to expand the role of additive manufacturing. This new class of software delivers insights that help engineers better understand the connections between materials, 3D printing processes, and part performance, with the goal of producing higher quality printed parts.
