3D Printing Between Expectations and Reality: Why “Plug-and-Play” Often Falls Short — An Interview with Julian Hoffmann of 3D Material-Shop

3D Material-Shop is a Germany-based provider that combines an online store for 3D-printing supplies with service offerings centered on additive manufacturing. Alongside its shop for 3D printers, 3D scanners, filaments, resins, and accessories, the company also runs a section for project-based inquiries.

Its service portfolio spans multiple process chains: for polymer parts, 3D Material-Shop offers FDM/FFF, SLA, and SLS, as well as MJF and PolyJet. For metal parts, the company relies on DMLS. Projects typically begin with an inquiry that includes CAD files and specifications, which helps narrow down the manufacturing route, material selection, and post-processing steps. This allows requirements such as dimensional accuracy, surface finish, or mechanical performance to be mapped to a suitable process early on.

That positioning targets both development work (prototypes, fit checks, and functional samples) and parts intended for small-batch production. The focus is less on “maker” experimentation and more on predictable outcomes across the printing process, material choice, and downstream operations. For technically experienced users, the key value is the combination of sourcing, manufacturing, and structured project handling—especially when designs iterate quickly or parts are needed on short notice.

Interview with Julian Hoffmann

In his conversation with 3Druck.com, CEO Julian Hoffmann explains how expectations around 3D printing and materials have shifted in recent years—and why guidance and stable, repeatable workflows matter more today than simply “running a print.” He also discusses common real-world hurdles and outlines which developments and business models could shape the market going forward.

How have requirements and expectations for 3D printers, materials, and accessories changed in recent years—and what trends are currently driving demand in your online shop and service business?

In recent years, requirements for 3D printers, materials, and accessories have become noticeably more professional. Today’s customers primarily expect reliable, repeatable results and are increasingly turning to engineering-grade plastics such as PA, CF-reinforced materials, TPU, or ASA. One particularly clear shift is that FDM is no longer used mainly for simple prototypes, but increasingly for functional parts and small-batch production. As a result, the need for consultation has grown—many customers want application-driven recommendations rather than simply buying standard materials. At the same time, demand is rising for process reliability, material drying, high-quality nozzles, and professional-grade accessories. In the service business as well, demand is moving toward precise parts, robust functional components, and targeted post-processing such as impregnation or mechanical finishing.

What typical challenges do you face in day-to-day work as a reseller and 3D-printing service provider—especially in consulting, material selection, or technology understanding—and where do you see the biggest customer misconceptions?

Day to day, we often deal with challenges around material selection, part design, and expectations. Many customers underestimate how strongly factors such as moisture, wall thickness, layer orientation, or slicer settings affect the outcome. There is often an assumption that 3D printing is a plug-and-play process—but without a design suited for AM, the right parameters, and regular maintenance, problems can appear quickly. A common misconception is that FDM can achieve the tolerances of CNC machining. We then explain what accuracy levels are realistic and which material is appropriate for the intended application. Another frequent question is about the “best material,” but that choice always depends on the use case. Good consulting can prevent a lot of frustration.

Which technical developments in printers, materials, or software have most strongly changed your product range and services in recent years?

Fiber-reinforced filaments, high-grade engineering polymers, and more advanced printing technologies have had the biggest impact on our product offering. Carbon- and glass-fiber filaments have enabled many new applications in the semi-professional segment, particularly for durable functional parts. In addition, more precise CoreXY systems, input shaping, and improved temperature control in printers have significantly increased quality. Slicer software has also made major leaps forward: automatic calibrations, optimized support structures, and better flow control lower the barrier to entry and improve process stability. In resin printing, new mechanically robust resins are making more functional components feasible. At the same time, post-processing is becoming increasingly important—for example, impregnation, smoothing, and surface optimization. These developments have made our portfolio more technical, more specialized, and more industry-oriented.

How do you expect the market for 3D-printing hardware, materials, and printing services to develop over the next five to ten years—especially regarding new applications, customer groups, and business models?

The 3D-printing market will continue to move toward industrialization and small-batch manufacturing. Companies increasingly recognize the advantages of fast, customized, and cost-efficient production of low volumes. That raises expectations for materials, process stability, and service providers that offer not only printing but end-to-end solutions. New customer groups—such as automation companies, machine builders, and startups—are also driving this trend. At the same time, the consumer market is becoming more professional, meaning technically more capable machines will become more widespread. New business models such as on-demand spare-part production, digital component libraries, and print farms are gaining relevance. We also expect innovation in more sustainable or higher-performance plastics. Overall, the market will become more diverse, more technically demanding, and significantly more service-driven.
