Service bureaus, which operate large clusters of printers for contract manufacturing, contribute significantly to hardware purchases as they scale capacity .
Many industries treat printers as essential equipment in their design and production workflows, embedding them into labs, prototyping rooms, production lines, and maintenance shops. Metal printing materials are growing the fastest because industries that require components with exceptional strength, thermal performance, and durability have found additive manufacturing uniquely capable of delivering designs that conventional methods cannot achieve. Metal powders allow aerospace and defense sectors to produce turbine blades, airframe components, and heat-resistant structures with internal cooling channels and optimized lattices that reduce weight while maintaining performance. Automotive manufacturers use metal printing to create lightweight brackets, custom tooling, and high-strength parts that must withstand mechanical loads during testing or on-road use. Hospitals increasingly rely on titanium and other biocompatible metals to produce implants that match a patient’s bone structure, improving surgical fit and recovery outcomes .
Metal powders also enable mining, energy, and heavy-equipment companies to fabricate replacement parts for machinery operating in remote locations, reducing long downtime periods. The refinement of metal powders, including improvements in particle size distribution, flow characteristics, and material purity, has allowed engineers to achieve more consistent mechanical behavior across prints. As sintering, heat treatment, and other post-processing techniques evolve, industries gain confidence in the structural performance of printed metals. Metal printing supports consolidation of multi-piece assemblies into single components, eliminating joints that can fail over time, and enabling engineers to reimagine parts based on performance goals instead of manufacturing constraints .
With the increasing pressure to streamline supply chains and localize production, metal additive manufacturing provides a path for manufacturers to reduce dependence on cast or machined parts imported from distant suppliers. Functional part manufacturing is growing the fastest because industries are increasingly using additive manufacturing not just for concept models but for fully operational components that perform under real conditions, shifting 3D printing from a design tool into a manufacturing strategy. Companies that once explored additive technology primarily for prototyping now rely on it to produce heat exchangers, brackets, housings, conduits, orthopedic implants, dental restorations, turbine components, and other parts that must endure wear, temperature fluctuations, pressure, or mechanical stress. This shift reflects a broader recognition that additive processes can produce geometries that offer superior performance compared to traditionally machined or molded parts, such as lattice structures that reduce weight or internal channels that improve cooling efficiency. The ability to fabricate parts on demand allows factories to minimize physical inventory, which is especially useful for industries that maintain equipment fleets in remote or unpredictable environments .
Engineers increasingly design components specifically for additive manufacturing, optimizing topology to achieve performance improvements while reducing material usage. As material libraries expand to include high-temperature polymers, reinforced composites, and advanced metal alloys, functional applications continue to grow across many sectors. Regulatory progress in sectors such as aerospace and medical devices has also played a role, as more printed parts gain certification for real-world use. The global push toward more localized and agile production encourages companies to produce end-use components internally rather than depending on long supply chains, making additive manufacturing an attractive alternative. The automotive industry stands as the largest user of 3D printing because it integrates additive manufacturing at nearly every stage of vehicle development and production, creating a constant and diverse demand for the technology .
Automakers rely heavily on additive manufacturing during early concept modeling, using printed shapes to evaluate ergonomics, aerodynamics, engine layout, and interior components before committing to expensive tooling. Once designs move beyond the conceptual phase, engineers turn to 3D printing for rapid iteration of functional prototypes, suspension components, housings, and under-the-hood parts that must withstand mechanical testing. Tooling is one of the biggest drivers of demand, as factories need countless jigs, fixtures, positioning tools, check gauges, and assembly aids to keep production lines running efficiently, and 3D printing provides these items faster and at far lower cost than traditional machining. The shift toward electric vehicles introduces new complexity, with battery cooling channels, lightweight brackets, cable routing systems, and thermal management components benefiting from geometries that only additive processes can produce .
Motorsports and high-performance vehicle manufacturers use additive manufacturing to create bespoke components optimized for weight reduction, structural stiffness, or aerodynamic behavior, allowing teams to test design modifications between race cycles. Additionally, the aftermarket and restoration segments use additive manufacturing to reproduce discontinued or niche interior and exterior parts that traditional suppliers no longer produce. Automotive companies also invest heavily in automation and digital manufacturing, making it easier to integrate additive technologies into broader production workflows. Because the industry operates globally and processes immense volumes of design work, prototyping, and tooling activities, it naturally becomes the largest vertical using 3D printing, with applications that span experimental design, validation, customization, and practical production far more extensively than many other sectors. Direct Metal Laser Sintering is growing faster than other additive technologies because it fulfills industrial requirements for producing high-performance metal components with complex geometries, consistent material properties, and reliable repeatability that match or exceed those of traditionally manufactured parts .
The process uses a concentrated laser beam to fuse metal powder in precise layers, giving engineers the ability to create intricate internal structures, channels, and lightweight lattices that would be impossible with casting, machining, or fabrication. Aerospace companies rely on DMLS to produce fuel system components, heat exchangers, turbine parts, and structural brackets that must endure extreme environments, and this need for advanced metal components has accelerated the adoption of DMLS across global engineering projects. Medical device manufacturers use the technology to fabricate orthopedic implants with bone-mimicking porosity or dental prosthetics that require exact patient-specific geometries, driving strong clinical demand. Automotive and motorsport teams appreciate its ability to consolidate multi-piece assemblies into single optimized components, reducing weight while increasing reliability .
The availability of engineered powders such as titanium alloys, nickel-based superalloys, stainless steels, and aluminum grades reinforces the versatility of DMLS. Advances in powder management, shielding gases, thermal modeling, and scanning strategies continually refine process stability, encouraging larger manufacturers to deploy DMLS for short-run production. As firms seek to localize manufacturing and reduce supply-chain dependence, DMLS offers the capability to produce critical metal parts internally rather than relying on cast or machined imports. Powder Bed Fusion has become the largest process category because it offers a unique combination of material versatility, part performance, and geometric complexity that appeals to industries ranging from aerospace to healthcare to industrial manufacturing. In metal applications, PBF allows engineers to create high-strength parts with fine microstructures, controlled porosity, and intricate cooling channels, enabling components to operate in demanding conditions such as high heat or heavy mechanical loads .
In polymer workflows, nylon-based PBF systems print durable, dimensionally stable parts without requiring support structures, allowing multiple components to be nested densely in a single build and expanding productivity for service bureaus and in-house production teams. Aerospace organizations depend on PBF for structural components that must pass rigorous certification procedures, while medical institutions rely on it to produce implants that conform to complex anatomical shapes. The technology’s inherent precision and repeatability give manufacturers confidence that printed components will meet consistent quality thresholds across multiple build cycles. PBF supports a broad library of materials, including engineering-grade polymers, titanium alloys, aluminum alloys, nickel superalloys, and specialized composites, allowing companies to use additive manufacturing for both prototypes and functional parts .
Research institutions frequently use PBF platforms to explore advanced alloys and powder blends, feeding continuous improvements back into industry. As sectors focus on reducing waste, improving energy efficiency, and creating parts with fewer joints or welds, PBF provides a clear path toward consolidated and optimized designs. Scanning software is growing faster than other software categories because industries increasingly depend on accurate digital capture and model reconstruction to support reverse engineering, quality assurance, and personalized manufacturing. As more companies integrate additive manufacturing into their operations, the need to convert physical parts into usable digital files becomes essential for modifying designs, verifying dimensions, and building digital inventories. Engineers use scanning software to analyze wear on components, compare printed parts against original CAD models, and detect deviations that could compromise performance .
In sectors like automotive and aerospace, where precision is critical, the ability to evaluate the geometry of printed parts ensures that tolerances remain consistent across production runs. Healthcare institutions rely on scanning tools to generate anatomical models for dental restorations, orthopedic implants, and surgical planning, making high-fidelity digital capture a requirement for patient-specific solutions. As scanning hardware becomes faster, more affordable, and more portable, scanning software evolves to process massive datasets, refine point clouds, and generate clean meshes that integrate seamlessly into design workflows. Manufacturers also use scanning software to digitize legacy components when original drawings are unavailable, enabling them to recreate or improve obsolete parts .
The expanding use of digital twins and simulation tools further increases the need for accurate scanned data that reflects real-world conditions. This convergence of inspection needs, personalization demands, and digital manufacturing workflows drives scanning software to grow more rapidly than other software categories in the additive manufacturing ecosystem.
