This comprehensive study arrives at a crucial juncture for the AM market, which, despite the global challenges posed by the recent pandemic, has demonstrated remarkable resilience and continued its impressive growth trajectory. The IDTechX analysis delves into four fundamental families of materials crucial to the industry’s advancement: polymers, metals, ceramics, and composites. For each of these categories, IDTechX offers insightful predictions, highlighting critical shifts such as the escalating importance of sustainability within the polymer segment and the growing prominence of extrusion processes in metal 3D printing. One undeniable conclusion from the report is that relentless innovation in materials will serve as the primary catalyst for the additive manufacturing sector’s ascension, continually delivering surprising advancements and opening new possibilities across countless applications.

While the additive manufacturing market, much like nearly every sector of the global economy, experienced significant disruption and weakening due to the COVID-19 crisis, it remarkably managed to not only persevere but also to thrive and underscore its inherent strengths. The pandemic, unexpectedly, provided an impetus for certain industry players to dedicate resources to longer-term substantive developments and to fundamentally re-evaluate their operational strategies. For instance, the widespread halting of offshore production compelled numerous companies to pivot towards the utilization of local resources, fostering shorter, more resilient supply chains, and prioritizing solutions that are inherently more respectful of the environment. This profound emphasis on sustainability is particularly pronounced and gaining immense traction within the polymer market segment, signaling a paradigm shift in how materials are conceived, produced, and utilized in 3D printing. This focus is driven by increasing consumer awareness, stricter regulatory frameworks, and a collective industry commitment to reducing environmental impact.

Polymers and Metals: Driving Towards Sustainability & Accessibility

Today’s leading material manufacturers are intensifying their efforts to produce high-performance filaments, resins, and powders derived from natural and renewable resources, moving away from traditional petroleum-based alternatives. This shift is fueled by a burgeoning demand for manufacturing parts that can be readily recycled or, at the very least, efficiently reused, thereby significantly reducing their overall carbon footprint. The topic of sustainability in additive manufacturing has gained considerable momentum, a point we extensively highlighted following Formnext 2021, where it became clear that 3D printing companies are not only mobilizing but also committing to swift action on this crucial subject. IDTechX’s report strongly corroborates this trend, underscoring its particular reinforcement within the polymers segment. The new generation of plastics entering the market are, according to the report, increasingly ecological, often based on natural feedstocks or incorporating a substantial proportion of recycled materials. Illustrative examples include the innovative partnership between UBQ Materials and Plastics App, which has successfully developed a filament engineered from industrial technical waste, or Fillamentum’s pioneering NonOilen material, which boasts 100% biodegradability and compostability. These developments signify a decisive step towards a more environmentally conscious and circular additive manufacturing ecosystem.

The polymer market’s pursuit of sustainability extends far beyond just filaments, encompassing a wide array of initiatives within the powders segment as well. Manufacturers are relentlessly striving to enhance the ‘refresh rate’ of their powders – the proportion of new powder required in each build – to minimize waste, optimize material utilization, and significantly reduce operational costs. Concurrently, there is a dedicated push to develop new plastics that are inherently recyclable and can be effectively re-integrated into the production cycle without compromising material integrity. A significant, albeit often overlooked, challenge in achieving widespread material circularity is the establishment of robust, dedicated recycling channels within each country, a complex logistical and infrastructural undertaking that requires industry-wide collaboration. Notable advancements in this area include Bluesint PA12, a groundbreaking 100% recyclable powder meticulously engineered by Materialise, setting a new standard for sustainable powder bed fusion. Another significant innovation is PP 3D High Reusability, an advanced polypropylene developed through a strategic partnership between chemical giant BASF and HP, emphasizing the importance of collaborative efforts in sustainable material development. This urgent imperative to discover and implement more sustainable solutions is unequivocally clear and is projected to intensify significantly over the coming years. We are not discussing distant future aspirations but rather concrete developments anticipated within the next five years. The industry’s awareness is palpable, and more than ever, additive manufacturing players are actively mobilizing resources and demonstrating a strong desire to enact tangible, positive change.

Shifting our focus to the realm of metals, the IDTechX study illuminates the impressive ascent of Fused Filament Fabrication (FFF) technology, a process conceptually inspired by the well-established metal injection molding (MIM) technique. This innovative approach enables the creation of complex metal parts through a streamlined, multi-stage process involving three key steps: initial printing of a “green” part composed of metal powder bound by a polymer, followed by a debinding step to remove the polymer binder, and finally, sintering in a high-temperature furnace to fuse the metal particles into a dense, solid component. The paramount advantage of metal FFF technology lies in its significantly lower initial capital cost relative to more expensive and capital-intensive powder bed laser fusion solutions, which typically employ one or more high-power lasers, or even electron beam melting (EBM) systems. This cost-effectiveness and simpler operational workflow make metal FFF an increasingly attractive option for a broader range of manufacturers, especially those looking to adopt metal 3D printing without the substantial initial investment traditionally associated with it, thereby significantly improving accessibility. Consequently, the number of manufacturers actively positioning themselves within this burgeoning market segment is rapidly expanding. Prominent players include industry pioneers like Desktop Metal and Markforged, alongside more recent entrants such as 3DGence with its innovative Element range of metal FFF 3D printers, BCN3D with its specialized metal printing pack, and the ambitious startup FuseLab. Furthermore, an exciting area of development involves certain companies striving to further simplify this process by completely eliminating the debinding step, which would represent a significant leap forward in reducing complexity, processing time, and overall cost. This particular development is certainly one to monitor very closely as it could redefine accessibility and efficiency in metal additive manufacturing.

The Expanding Frontiers: Growth of Ceramics and Composites

The IDTechX report also provides illuminating insights into the substantial expansion of ceramics within additive manufacturing, a topic the firm has previously explored in other comprehensive studies. The report confidently projects that the ceramic additive manufacturing market is poised to reach an impressive value of $400 million by 2032, representing an astonishing seven-fold increase from its current valuation. This remarkable growth trajectory is primarily attributable to the rapid development of innovative new materials, driven by the synergistic efforts of three distinct types of industry players. Firstly, the report highlights the increasing number of conventional manufacturing companies entering this specialized niche for the first time, recognizing the unique advantages 3D printed ceramics offer in various applications, from aerospace components requiring high heat resistance to custom medical implants demanding biocompatibility. Secondly, chemical companies, traditionally focused on broader material markets, are demonstrating a heightened interest in ceramics, actively developing and offering dedicated solutions tailored for additive manufacturing processes, such as advanced slurries, binders, and photo-curable resins optimized for specific ceramic properties. Finally, the formation of strategic partnerships across the industry is significantly broadening the spectrum of possibilities, enabling collaborative research and development that leads to the conception of novel materials specifically designed for ceramic additive manufacturing. These partnerships accelerate innovation, pooling expertise and resources to overcome technical hurdles and expand the application potential of these high-performance materials. Much like the advancements in metal FFF, the evolution of ceramic 3D printing is an area that warrants close observation, promising to unlock new functionalities and applications previously unattainable with traditional manufacturing methods.
