What Endless Industries does

Endless Industries GmbH is a Berlin-based Deep Tech startup founded in 2021 that develops automated manufacturing systems for continuous fiber-reinforced composite parts production. The company targets mission-critical applications across three verticals: aerospace (lightweight structural components), orthotics (patient-customized devices, with reference customer Ottobock), and resilience/defense (where it claims to compress development cycles from years to weeks). It positions itself as building "Europe's composite powerhouse," funded by German government programs, regional development capital, and venture capital.

The company's core offering is an integrated system comprising three proprietary components. First, Endless Fiber Materials—thermoplastic composite compounds developed and produced in-house in Germany, currently PETG-eCF 3K with PA6-ECF 3K in development. Second, patented Process Heads—printheads designed for precise placement of pre-impregnated continuous carbon fiber filaments, featuring controlled fiber and matrix guidance, defined temperature zones, process pressure control, and an integrated cutting unit. Third, Akio software—a design and process-control platform that automatically plans optimal fiber paths from STL files, generates carbon fiber reinforcement structures inside 3D models, and adjusts manufacturing parameters in real time to ensure reproducibility from prototype to series production.

Endless Industries monetizes via an enterprise field sales motion, selling complete systems (process heads, materials, and Akio software) plus professional services on a quote-based, multi-year contract basis to industry leaders and research institutions. Disclosed deployments include Ottobock, Seeger Gesundheit, MUUUV, RWTH Aachen, and TU Hamburg. With roughly 15 employees, the company is founder-led (CEO Stephan Knopf, CTO Dr. Mathias Czasny, CSO Dr. Moritz Ebeling-Rump) and operates as a private limited company (HRB 254067, Amtsgericht Charlottenburg, Berlin).

Core offering

Endless Industries develops and delivers an automated manufacturing system for continuous-fiber composite parts production. The integrated offering combines proprietary thermoplastic Endless Fiber materials, patented process heads that precisely place and cut continuous carbon fibers, and the Akio design and process-control software that automates fiber-path planning and parameter control from STL files through series production. The system is sold to enterprise customers in aerospace, orthotics, and resilience/defense and is delivered with installation and support services.

Product overview

Endless Industries offers an integrated automated carbon fiber manufacturing system consisting of three core components: proprietary Endless Fiber materials (thermoplastic composite compounds including PETG-ECF 3K and upcoming PA6-ECF 3K), patented Process Heads for precise continuous fiber placement, and Design Software Akio for process control and fiber path planning. These components work together as a unified system: materials provide the core, process heads enable precise fiber placement, and Akio software orchestrates the entire workflow from design through production.
