AM Service providers are a key segment to analyze as they are both part of the “core AM industry”, together with AM hardware and AM materials, and they can also be considered as a vertical adoption segment, like Aerospace, Automotive, etc. As a part of the core AM industry, AM service providers serve all different verticals by providing printed parts. Assessing the unit numbers, average size and average cost of these parts enables us to assign a value to the parts that vertical AM adopters produce internally.

The emergence of 3D printing services

The rise of 3D printing services began with the adoption of rapid prototyping in the early days of AM. This approach allowed companies to quickly create physical models of their designs, significantly cutting down the time and cost of traditional prototyping methods. Firms could send their digital designs to a service provider, who would produce the prototype using cutting-edge 3D printing technologies such as stereolithography (SLA) and selective laser sintering (SLS). Once the prototype was ready, it would be sent back to the client for evaluation. Key players in this early market included companies like Materialise and Proto Labs, which were among the first to offer rapid prototyping services at scale, setting the stage for the modern AM service industry.

As AM technology matured, so did the capabilities of 3D printing service providers. What once was limited to rapid prototyping has expanded into producing final parts and even complete, end-use products. The evolution from prototyping to production marked a significant shift in the AM industry. Companies began turning to 3D printing services not just for one-off prototypes but for small-batch and mass production of customized components. The arrival of this era gave rise to the AM factories—facilities equipped with large fleets of industrial 3D printers capable of handling large production volumes. These modern service providers pushed the limits of AM, offering both businesses and individual consumers the ability to create complex, high-quality parts on demand.

From rapid prototyping to AM factories

The advent of AM factories represented a significant leap from traditional 3D printing services. Unlike earlier service models focused on single or low-volume prints, AM factories are equipped with vast arrays of printers, advanced automation technologies, and digital workflows. They can produce parts at a larger scale, often with quicker turnaround times and reduced costs. What sets AM factories apart is their ability to offer full-scale production capabilities, from customized small-batch runs to mass production of high-quality parts. These facilities represent a new breed of 3D printing service providers, focused not just on offering prototypes but on providing businesses with full production capabilities through AM technology.

Rapid prototyping remains one of the most significant contributions of 3D printing services to product development. Traditionally, creating prototypes involved extensive time and resources, particularly when working with complex designs. With the advent of 3D printing, rapid prototyping revolutionized this process by allowing engineers to quickly test designs, make iterations, and optimize final products. Rapid prototyping typically employs technologies like SLA, SLS, and fused deposition modeling (FDM), each offering different benefits in terms of material properties, accuracy, and speed. This allowed industries ranging from aerospace to consumer goods to innovate faster and bring new products to market with reduced risk and cost.

Companies like Materialise and Proto Labs were pioneers in offering rapid prototyping services. They provided clients with access to cutting-edge 3D printing technologies without requiring them to invest in expensive equipment. Materialise, for example, became known for its innovations in software and design solutions, while Proto Labs established itself as a leader in rapid manufacturing through its investment in digital factories. These companies set the standard for the broader AM service industry, establishing 3D printing as a viable alternative to traditional prototyping and manufacturing methods.

The rapid growth of AM has also led to the development of global networks of 3D printing service providers. Companies such as Xometry, Fictiv, and Makerverse have built platforms that connect businesses with a global network of AM service providers. These networks allow for distributed manufacturing, which enables companies to produce parts closer to where they are needed. This is particularly beneficial for industries like healthcare and aerospace, where the ability to rapidly produce and deliver parts on demand can significantly reduce downtime and logistics costs.

Distributed manufacturing is one of the most significant benefits of working with global AM networks. Rather than centralizing production in one location, parts can be produced closer to where they are needed, reducing shipping costs and lead times. This model is made possible by the widespread availability of 3D printing services across the globe, allowing businesses to take advantage of local manufacturing resources. Distributed manufacturing also allows for greater customization, as parts can be tailored to specific needs and produced on demand.

Automation and digital workflows in AM

As the scale and complexity of AM services have grown, so too has the integration of automation and digital workflows. Automation technologies such as advanced robotics and sophisticated software platforms are now commonplace in AM factories, helping to streamline the entire production process from design to final part. This not only improves efficiency but also reduces the potential for human error, resulting in higher-quality parts. Furthermore, digital workflows enable seamless integration between design, production, and quality control, allowing for faster turnaround times and greater scalability.

The introduction of advanced robotics, coupled with powerful AM software, has revolutionized production capabilities in AM factories. Robots are now used for everything from preparing prints to post-processing, reducing the need for human intervention and increasing the speed of production.
