3D Printing Materials: A $29.5 Billion Opportunity Ripe for Innovation
Jun 20, 2022 Sona Dadhania
Polymer, metal, wax, sand, concrete - as the 3D printing technology landscape has grown in diversity and complexity, so has the variety of materials compatible with these many processes. Whereas 3D printing used to be synonymous with low-cost thermoplastics for less demanding applications, it now sees more unique and high-performance materials enter the market annually, from metal-matrix composites to bio-ceramics to recycled plastics. This portfolio of compatible materials continues to expand as end-users demand higher quality products, greater choice, flexibility, and in the case of prototyping, materials that accurately mimic the final product's appearance and behavior. Importantly, this wider materials portfolio comes alongside increased adoption of additive manufacturing (AM), as important end-users begin to fully understand the value-add that 3D printing brings to their supply chain.
With users spanning valuable industry verticals like medicine, automotive, and aerospace, there is a continuing drive to expand the materials market for AM. With every new material launch, comes an additional application for 3D printing to explore. The growth potential for AM materials differs from printing equipment, as operational legacy printers continue to consume materials. Therefore, this segment of the 3D printing value chain represents a tremendous opportunity: IDTechEx forecasts that the global market for 3D printing materials will be worth $29.5 billion in 2032.
Polymers: a dynamically shifting landscape
Since the 2010s boom in desktop printing, polymers have become the public face of the AM materials market. In terms of tonnages, they are still the most in-demand class of materials for 3D printing. When asked about additive manufacturing, most people show familiarity with low-cost filaments like PLA and PETG. However, with this familiarity comes the perception that polymer 3D printing is only suitable for simple applications like prototyping. Now, companies are changing this perception by bringing more functional and higher-performance polymers to market.
One of the more popular performance polymers are fiber-reinforced polymer matrix composites (FRPs). The strength and stiffness benefits brought by carbon fiber are undeniable, and exploration into continuous carbon fiber extrusion opens a new opportunity for complex composite parts. Beyond composites are high-temperature thermoplastics, which materials suppliers and printer OEMs continue to tune for ease of printability. Additional polymers receiving interest include foams, recycled plastics, bio-based polymers, and polymers with additives like nanocarbons. As these developments continue to emerge, IDTechEx expects to see the face of polymer AM materials markedly shift over the next decade.
Metals: moving beyond powders
With metal additive manufacturing, powders are the dominant feedstock, comprising the majority of revenue and mass demand in the metal materials market. However, with cost and printability considerations in mind, printer OEMs are beginning to examine alternate feedstocks for metal 3D printing. One long-standing competitor is lower-cost metal wire, compatible with wire-directed energy deposition, that other processes are beginning to incorporate like a magnetohydrodynamic deposition. Another is metal injection molding pellets, which pellet extrusion companies are utilizing to extrude parts at even cheaper prices than metal polymer filament extrusion, a different emerging metal feedstock. Lastly, bound metal paste is seeing some traction as a safer alternative to powder, which has handling concerns. While IDTechEx does not foresee metal powders losing its position as the major feedstock, IDTechEx forecasts that these emerging feedstocks will contribute more and more to the growth of the metal 3D printing materials market.
