Getting to Know Jörg Gerken
Marco: Let’s start from the beginning. Tell us a bit about your background and what brought you to open your own 3D printing service?
Jörg: “With a background in mechanical engineering from TU Hannover and a PhD in metal-based additive manufacturing from the Laser Zentrum Hannover, I co-founded rpm in 1997 with my colleague and friend Dr. Klaus Kreutzburg. Together, we established SLS (selective laser sintering) technology in the market for fast and resilient plastic prototypes, earning us a place among the pioneers of 3D printing. We chose the path to additive manufacturing because we were, and still are, excited about the many ways these technologies can solve our customers’ challenges. Our deep expertise and passion for additive manufacturing drive us to solve complex challenges and turn our customer ideas into reality. We are delighted to finally see our vision of AM series production from over 25 years ago become a reality.“

Discovery of BASF Forward AM
Marco: Moving onto our partnership, how did you first come across BASF Forward AM, and what motivated you to become a partner?
Jörg: “Our first encounter with BASF Forward AM was driven by a customer request that sent us on a mission. One of our clients needed polypropylene (PP) for selective laser sintering, a material that was not widely available. Determined to find the best solution, we sourced the market and discovered BASF Forward AM.
What made us decide to partner with BASF Forward AM was more than just their ability to supply the PP we needed. It was their reputation for innovation, quality, and a collaborative spirit that matched our own. They didn’t just offer a product, they offered their expertise, support, and a commitment to find the best solution for the customer, which aligns perfectly with our philosophy.
Partnering with BASF Forward AM allowed us to meet our customer’s needs and exceed their expectations. Their advanced materials and technical support have enabled us to deliver even more innovative solutions to our clients. This partnership is built on shared values and a mutual passion for advancing 3D printing technology. We’re thrilled to work with BASF Forward AM and excited about the future possibilities this close partnership brings.”
Deep Dive into BASF Forward AM's Ultrasint® TPU 88A and PA11 CF
Marco: Let’s talk about our PA11 CF and TPU 88A for your SLS 3D Printers. How have they benefited your operations, and what has your experience been with the quality and performance of these products?
Jörg: “These materials have significantly elevated our capabilities and offerings. The future of additive manufacturing with these materials lies in series production.
PA11 CF has become a game-changer for us. Its superior mechanical properties, including high tensile strength, have allowed us to produce parts that are not only robust but also lightweight due to the high strength-to-weight ratio. This has been particularly beneficial for our clients in the automotive and sport sectors, where performance and reliability are paramount. Additionally, PA11’s bio-based origins align with our commitment to sustainability, adding an extra layer of value for our environmentally conscious customers.
TPU 88A, on the other hand, has opened up a world of possibilities with its exceptional flexibility and durability. This material is perfect for applications requiring elastic properties, such as sports equipment and orthopedic technology. Its resilience and ability to maintain performance under stress have impressed both us and our clients, making it a go-to material for challenging projects.
The quality and performance of BASF Forward AM’s materials have consistently exceeded our expectations. Their PA11 CF and TPU 88A not only meet the high standards we set for our products but also push the envelope, allowing us to innovate and deliver superior solutions. The consistent, reliable results we achieve with these materials have helped us build stronger relationships with our clients, who trust us to deliver cutting-edge, high-performance parts.
In short, BASF Forward AM’s PA11 CF and TPU 88A have been instrumental in enhancing our business. They provide us with the tools to create advanced, reliable, and sustainable solutions that meet and exceed the demands of our diverse customers. Our partnership with BASF Forward AM has truly empowered us to push the boundaries of what’s possible in SLS 3D printing.
“In short, BASF Forward AM’s PA11 CF and TPU 88A have been instrumental in enhancing our business. They provide us with the tools to create advanced, reliable, and sustainable solutions that meet and exceed the demands of our diverse customers.“
In close cooperation, Forward AM, rpm, and Canyon employed the full potential of 3D printing – Virtual Engineering combined with the precise material needed to realize the design – and harnessed the possibilities of 3D printing to the fullest resulting in one of the lightest bike computer mounts available on the market.
Applications of TPU and PA11
Marco: In which applications do you find our materials to be most advantageous, and which specific uses can benefit the most from this material?
Jörg: “One notable application is the Canyon bike computer mount. We have sold 18,000 mounts until today, with a four-month time to market. The mounts, made from PA11 CF, printed on our Farsoon HT403P, depowdered by the S1 from AMSolutions and vapor smoothed using the SF100 from AMT PostPro, weigh just 17 grams and offer exceptional durability and performance.
Another standout application is a custom shoe insole made from TPU 88A black, designed to correct foot problems. This material provides a lightweight and personalized solution for the customers of Paul Hast GmbH with their 4Point insole.
The specific properties of PA11 CF and TPU 88A black have significantly enhanced these products, offering clear advantages in terms of durability and performance. Our customers benefit from these high-quality, innovative solutions tailored to their precise needs.“
Marco: Could you share your experiences with any of the specialized services and solutions you utilize? How do these services support your efforts in improving customer satisfaction?
Jörg: “We utilize the BASF Forward AM’s Ultrasim® 3D Lattice Library to streamline our development of lattice structures, enhancing our ability to innovate rapidly. This advanced tool eliminates multiple iteration cycles, accelerating our design process and enabling us to deliver optimized solutions swiftly. By integrating this specialized service, we not only enhance efficiency but also elevate customer satisfaction by consistently delivering high-quality, finely tuned products that meet and exceed expectations. This approach underscores our commitment to pushing the boundaries of what’s achievable in additive manufacturing, ensuring our clients receive the best solutions in the shortest timeframes possible.“

A light wrap up!
Marco: To end on a fun note, what’s the strangest or most unusual request you’ve ever received for a 3D printing job?
Jörg: “To end on a humorous note, one of the unusual requests we’ve handled was an art project that tasked us with sintering an endless plastic filament to weave into a cloud or sphere shape. Let’s just say, unpacking and depowdering that component turned into quite an adventurous endeavor! It was a delightful reminder of the endless creativity and unique challenges that come with the world of 3D printing.
Thank you, Jörg!
