The development and manufacture of modern laboratory, diagnostic and medical devices is now more than ever caught between technological innovation, regulatory requirements and economic pressure. The demand for precision, reliability and miniaturisation is constantly growing, as are the requirements for documentation, safety and digital integration into existing systems.
At the same time, many manufacturers are struggling with limited resources, increasing cost pressure and a growing shortage of skilled labour. System complexity is increasing, while the timeframe for development and market launch is getting ever shorter.
This article highlights the main challenges in device manufacturing, especially in analytical laboratory technology, clinical diagnostics and medical technology. It also provides a clear understanding of the framework conditions that must be met when developing innovative solutions nowadays.
The compact design of modern devices presents developers with enormous challenges. Numerous functions, including sensors, fluidics and electronic components, have to be installed in a very small space in laboratory, diagnostic and medical devices. At the same time, the demands on ergonomics, mobility and ease of transport are on the rise. In addition, miniaturised components must not only be powerful, but also reliable and durable. The limited installation space requires creative redesigns and sophisticated system architectures where every millimetre counts. This often has an impact on material consumption and weight.
Many manufacturers are faced with the challenge of developing complex mechatronic systems with small teams working to full capacity. There is often a lack of specialised knowledge, particularly in areas such as automation, fluidics, electronics or software integration. However, the development of laboratory, diagnostic and medical devices requires in-depth technical understanding, from the initial idea to series production. Companies whose core expertise does not include the areas of drive technology or system integration are increasingly benefiting from external partners who provide that specific expertise and resources.
The economic pressure in device manufacturing is growing, especially for small and medium-sized series. Customers expect high-performance, reliable and cost-effective solutions. However, developing new devices is expensive, especially when the number of variants is large and the quantities small. In order to remain competitive, many manufacturers rely on modular assemblies, standardisation and external support with development. This shortens development times and reduces costs without compromising on quality or functionality.
The integration of fluidics, electronics, mechanics, sensors and software in a single device leads to a high level of system complexity. To ensure error-free operation, the interfaces must be precisely harmonised. Even minor discrepancies in the system architecture can lead to considerable problems during use or certification. That is why a comprehensive approach to system integration, ideally with interdisciplinary teams, is crucial for success.
Laboratory, diagnostic and medical devices have to work reliably and precisely for many years, often under changing environmental conditions. The requirements for accuracy, repeatability and long-term stability are very high, especially for sensitive applications such as blood analyses or molecular biological tests. A sturdy design, high-quality components and carefully considered quality assurance are crucial to prevent failures and ensuring patient safety.
For manufacturers of laboratory, diagnostic and medical devices, compliance with legal requirements such as the MDR (Medical Device Regulation), ISO 13485, FDA regulations or IEC 61010 standards is mandatory. At the same time, this is extremely complex. Documentation, traceability and validation must be taken into account as early as the development phase. Errors or omissions can lead to considerable delays, certification problems or even recalls. That is why an in-depth understanding of regulatory requirements is essential.
The time from a product idea to market launch is getting shorter and shorter. At the same time, the demand for customised variants and flexible quantities is increasing. Manufacturers must thus be able to react quickly to market changes and efficiently develop, test and produce new series devices. Agile development processes, modular platforms and close collaboration with experienced partners help to significantly shorten the time to market.
Laboratory, diagnostic and medical devices are now increasingly networked and data-capable. They communicate with hospital IT systems, cloud platforms or laboratory information systems, enabling data to be used and analysed more efficiently. This digital networking places high demands on interfaces, software architecture and, in particular, IT security.
The Cyber Resilience Act (CRA), which will come into force in December 2027, will make cyber security a mandatory part of CE labelling for all products with digital elements. Manufacturers must then ensure that all developments follow the principle of "secure by design" and "secure by default".
In addition to technical performance, the ease of maintenance and servicing of devices is becoming increasingly important. Manufacturers are faced with the task of designing systems in such a way that they require little maintenance, are easier to service and, ideally, enable predictive maintenance. The aim is to minimise downtime, extend service life and organise servicing efficiently. Modern approaches such as predictive maintenance make it possible to recognise maintenance requirements at an early stage, before a failure occurs.
Today, sustainability is a decisive competitive factor and has long since ceased to be simply a "nice to have". Manufacturers are faced with the challenge of reducing the material and energy consumption of their devices without compromising on performance or quality. Resource-saving designs, energy-efficient components and recyclable materials are key tools for combining environmental responsibility and economic success.
The challenges mentioned here make it clear that the demands placed on device manufacturers in the life science industry are high and often cannot be met with conventional standard components. Generic approaches quickly reach their limits, especially when it comes to precision, integration and regulatory safety.
