Who We Are.
Welcome to Karsten River—where sustainability meets innovation and artistry through large-scale additive manufacturing.
Founded in Los Angeles by award-winning product designer and robotics engineer Karsten River Heideman, our mission has always been clear: transform challenging, post-consumer waste streams into extraordinary architectural and interior design masterpieces. With cutting-edge robotic extrusion and adaptive AI-driven controls, our team creates captivating and sustainable solutions that redefine what's possible in contemporary design.
Our Journey
Karsten River was born from a commitment to address two significant global issues simultaneously: environmental waste and the demand for sustainable, customizable construction materials. Through hands-on experimentation with challenging recycled materials, including discarded carpets and mattresses, we have pioneered a groundbreaking, modular 3D printing platform. Our technology dynamically adapts to material variability, producing structurally robust and visually compelling designs for both residential and commercial spaces.
The Karsten River Difference
What sets us apart isn't just our technology—it's our relentless dedication to circular economy principles. Unlike conventional 3D printing methods, our adaptive system harnesses real-time generative design algorithms, enabling us to create custom products uniquely tailored to the properties of each recycled feedstock. From sound-absorbing wall panels and sculptural furniture to innovative lighting solutions, each Karsten River creation embodies sustainability and sophistication.
