Annually, the company undertakes the modification of approximately 1,000 units, providing comprehensive support to its customers throughout the entire vehicle lifecycle – from initial design and production to the eventual resale of the specialized vehicles at the end of their operational life. Today, we delve into their innovative application of Selective Laser Sintering (SLS) technology to radically transform and customize the interiors of mass-produced vehicles into highly functional police cars.

MOSOLF’s Customization Imperative: Tailoring Every Police Vehicle

MOSOLF’s operational model revolves around taking standard production vehicles—including cars, trucks, and vans—and meticulously adapting them to the precise, often idiosyncratic, specifications of each client. The unique challenges associated with this level of customization have been profoundly addressed and overcome through the integration of additive manufacturing. This is particularly true for newer vehicle models, which tend to feature more intricate designs and components, leaving increasingly less space for the inclusion of essential communication or signage systems. The inherent design flexibility offered by 3D printing has emerged as the pivotal solution to this complex challenge, enabling MOSOLF to engineer and produce bespoke components that fit seamlessly into every available nook and cranny of the vehicle’s interior.

The complexity of MOSOLF’s customization work is further amplified by the fact that each police force maintains distinct requirements concerning ergonomics, specific equipment integration, and interior layouts. MOSOLF currently manufactures and converts vehicles for no fewer than 17 different police forces across Germany, each presenting its own unique set of specifications and preferences. This diversity in demand would typically pose significant logistical and production hurdles for traditional manufacturing methods. However, thanks to the agility and adaptability of 3D printing, the company is able to rapidly adjust its designs and production models to accommodate these variations with remarkable efficiency. This capability is not just an advantage; it is absolutely essential for MOSOLF to consistently meet the exceptionally high levels of personalization demanded by its diverse customer base, ensuring that every vehicle is perfectly optimized for its intended operational role.

Selective Laser Sintering (SLS) 3D Printing: The Ideal Production Method

Among the various additive manufacturing technologies available, Selective Laser Sintering (SLS) has proven to be the unequivocally ideal process for MOSOLF. The rationale behind this choice is compelling: SLS 3D printing delivers an optimal combination of superior part quality, exceptional precision, and robust durability, all while enabling the simultaneous production of multiple components in a highly cost-efficient manner. Prior to adopting SLS, MOSOLF utilized FDM (Fused Deposition Modeling) technology. The transition to SLS marked a significant upgrade, allowing the company to dramatically increase its production capacity for the specialized parts it requires, and crucially, to achieve the stringent industrial standards demanded by the automotive and security sectors.

Furthermore, traditional manufacturing methods typically employed for vehicle components are inherently better suited for high-volume production runs of standardized products. These methods often involve expensive tooling and lengthy setup times, making them economically unviable for unique, low-volume requirements. In stark contrast, MOSOLF’s customers, the various police forces, consistently require only small batches of highly customized parts. This fundamental mismatch between demand and traditional supply methods is precisely why 3D printing, particularly SLS, has emerged as the perfect solution for the rapid, on-demand production of these unique and specialized components.

Unmatched Speed and Agility in Production

One of the most significant strengths and transformative benefits of SLS technology for MOSOLF is its unparalleled ability to produce finished parts in an incredibly short timeframe. With SLS, MOSOLF can now manufacture final, ready-to-install parts in as little as 24 hours. This represents a monumental improvement compared to the traditional lead times, which often stretched from four to six weeks. The remarkable agility and speed of this production method were key factors that decisively encouraged MOSOLF to fully embrace the technology. Today, an impressive 80% of their specialized parts are produced using SLS technology, primarily utilizing advanced systems such as Formlabs’ Fuse 1+30W SLS 3D printer. This rapid turnaround not only accelerates project timelines but also allows for greater flexibility in responding to evolving requirements and urgent demands from their clients.

The Material of Choice: Robust Nylon PA12

The material predominantly used by MOSOLF for these critical components is nylon, specifically PA12 powder. This choice is deliberate and crucial, primarily due to nylon’s exceptional resistance to heat and its superior mechanical properties. PA12 powder ensures that the printed parts maintain their structural integrity, dimensional stability, and aesthetic quality even when subjected to adverse environmental conditions. For instance, police vehicles are often left exposed to direct sunlight for extended periods during the summer months, leading to significant temperature fluctuations within the vehicle’s interior and on exterior mounted parts. Nylon PA12’s ability to withstand these high temperatures without deforming, cracking, or losing strength is paramount, guaranteeing the reliability and longevity of the additively manufactured components in real-world operational scenarios. Furthermore, its inherent durability and resistance to wear and impact make it an ideal material for components that endure constant use and potential stress within a demanding law enforcement environment.

The Tangible Impact: A Revolution in Law Enforcement Vehicle Design

The profound impact of 3D printing on MOSOLF’s operations and, by extension, on German police vehicles, cannot be overstated. In a revealing interview with Formlabs, Carsten Busam, Head of Project Planning at MOSOLF Special Vehicles GmbH, provided a compelling insight into the widespread adoption of this technology. He stated, “I estimate that every third police van [in Germany] now contains additively manufactured parts. At MOSOLF, we are now so far advanced with 3D printing that there is no vehicle that leaves our yard without an additively manufactured part in it. We now 3D print around 5,000 parts per year, but we are on an upward trend, which means that we have at least three parts in every vehicle if not more.” This testimony highlights not just an incremental improvement, but a fundamental shift in their manufacturing paradigm. The statistic that every vehicle leaving their facility contains at least one 3D printed part underscores the technology’s integral role, moving beyond niche applications to become a core part of their production strategy. The production of 5,000 parts annually, with a clear upward trajectory, demonstrates the significant scale and growing importance of additive manufacturing in meeting the evolving demands of modern law enforcement agencies.
