Unlocking High-Performance PEKK SLS 3D Printing: Verne AM Labs Introduces the Revolutionary STROM System

The landscape of additive manufacturing is constantly evolving, yet certain challenges persist, particularly in the realm of Selective Laser Sintering (SLS) 3D printing with high-performance polymers. It is a well-known fact within the industry that the number of SLS 3D printers capable of processing these advanced materials remains notably limited. Among these, SLS-PEKK (Polyetherketoneketone) 3D printing has faced significant hurdles in gaining widespread market adoption. The primary barriers have been the substantial acquisition costs associated with specialized high-temperature SLS systems, which are considerably higher than those for traditional SLS printing, coupled with the intrinsically high price of PEKK powder itself. These factors have historically confined the use of such advanced materials to highly specialized applications and research facilities with generous budgets.

However, a groundbreaking development is poised to disrupt this status quo. Verne Additive Manufacturing Labs, a company with a proven track record of innovation in additive manufacturing, has designed and is now introducing a new SLS printing system named STROM. This innovative platform aims to dismantle the existing barriers, making high-performance SLS printing with materials like PEKK more accessible, user-friendly, and cost-effective for a broader industrial audience.

Verne AM Labs’ journey towards this milestone began in 2014 when the founding team established the startup Norge. Norge quickly made a name for itself by developing what was then considered the first truly affordable SLS 3D printer. This pioneering system integrated functionalities previously exclusive to expensive industrial-grade machines, marking a significant breakthrough in making advanced additive manufacturing technology more democratic. Over the years, Norge garnered international recognition for its reliable laser sintering printing systems, which found successful applications in various industrial sectors across Europe and Asia. Building on this legacy of innovation and accessibility, Verne AM Labs is now embarking on its most ambitious project yet: the STROM project. The core objective of STROM is to elevate high-performance SLS printing, particularly with materials like PEKK, to new heights of accessibility and operational simplicity through the development of a cutting-edge printer and an integrated ecosystem. The dedicated team at Verne is currently immersed in the intricate stages of software development and machine design. Prototype testing is strategically planned for the fall of 2024, a crucial phase that will refine the system’s capabilities and validate its performance. The ultimate goal, reflecting their commitment to rapid market deployment, is to commence series production of the STROM system by June 2025.

The temperature control system, which has an IR camera

The new STROM PEKK SLS solution is engineered to deliver exceptional performance and versatility. Boasting a generous build volume of 220 x 250 x 400 mm, which translates to approximately 22 liters, it provides ample space for producing a wide array of industrial components. This substantial build envelope, combined with its advanced capabilities, enables true high-temperature SLS printing. This critical feature makes the STROM system ideally suited for processing demanding, high-performance thermoplastic materials such as PEKK, PEEK, and other engineering-grade polymers that require elevated temperatures for optimal sintering. Its robust design and precise control mechanisms ensure compatibility with the stringent requirements of leading research centers, advanced manufacturing laboratories, and Original Equipment Manufacturers (OEMs), positioning it as a powerful tool for innovation and production across these vital sectors.

A particularly impressive aspect of the STROM printer lies in its unparalleled thermal capabilities. The build chamber is capable of reaching and maintaining exceptionally high temperatures, up to 380°C. This extreme temperature capacity is absolutely essential for the successful sintering of high-melting-point polymers like PEKK, ensuring optimal material fusion and the desired mechanical properties in the final part. This superior thermal control is not merely a matter of reaching high temperatures; it is meticulously managed by an intelligent temperature control system. This sophisticated system integrates an infrared (IR) camera, which provides real-time, precise monitoring of the thermal distribution within the build chamber. This continuous feedback loop allows for dynamic adjustments, guaranteeing uniform temperature profiles and preventing inconsistencies that could compromise part quality. Beyond temperature management, the STROM printer incorporates advanced quality assurance protocols. It offers layer-by-layer image analysis quality control, a feature that meticulously scrutinizes each printed layer for potential defects or anomalies. This proactive monitoring ensures that tools and parts are precisely built to specification, significantly reducing the risk of failures and waste. Furthermore, Verne AM Labs has leveraged the power of artificial intelligence (AI) to optimize critical aspects of the printing process. AI is actively utilized in refining scanning strategies and managing laser power. By intelligently adapting these parameters, the system can efficiently enhance the mechanical properties of the printed components, making them stronger and more durable, while simultaneously boosting printing speed. This AI-driven optimization translates into higher throughput and superior part performance. The versatility of the STROM PEKK laser sintering 3D printer extends beyond just high-performance materials. It is also fully compatible with a wide range of standard SLS powders, including widely used materials like PA12, PA11, PP (Polypropylene), TPU (Thermoplastic Polyurethane), and PA6. This broad material compatibility makes the STROM a truly adaptable industrial tool, capable of addressing diverse application needs across various industries.

Verne AM Labs envisions the STROM printer not merely as a standalone device, but as a central component of a comprehensive, intelligent additive manufacturing ecosystem. This integrated approach aims to streamline the entire workflow, from pre-processing to post-processing, maximizing efficiency and minimizing manual intervention. The ecosystem includes several innovative systems designed to enhance productivity and part quality. One such component is IntegAM Fibroblast Air, an advanced powder removal system. This system automates the often tedious and time-consuming process of depowdering, making it faster, cleaner, and more consistent, thereby significantly improving post-processing efficiency and worker safety. Another crucial element is IntegAM SurfPro, a dedicated solution for surface finishing. Achieving desired surface aesthetics and functional properties is critical for many applications, and SurfPro ensures that printed parts can meet rigorous standards with ease. Finally, the SM-1 automatic powder management system represents a leap forward in material handling. This intelligent unit automates the entire powder lifecycle, including automatic sieving, precise mixing of fresh and recycled powders, and efficient transfer of the powder to and from the printer. This level of automation ensures optimal powder quality, reduces material waste, and contributes to a safer, more organized working environment, all of which are vital for industrial scalability and cost-effectiveness in additive manufacturing.
