The Allstruder: an open syringe extruder for every 3D printer.

The Allstruder is a modular syringe pump and extruder system engineered to combine high performance, broad compatibility, and exceptional ease of use. It is a compelling alternative to existing material extrusion tools across bioprinting, embedded 3D printing, food printing, ceramics, and multi-material applications. Validated across multiple laboratories and use cases, the Allstruder has demonstrated reliable performance and adaptability with a wide range of materials, syringe sizes, and 3D printer platforms. Designed specifically for additive manufacturing, it is configurable for nearly any extrusion-based 3D printer, supports syringes from 0.1 to 100  mL, and relies exclusively on standard, off-the-shelf components. Its architecture emphasizes adaptability through modular mounts and interchangeable syringe adapters, allowing rapid reconfiguration for different tools, materials, and workflows. With a simple, durable, and modifiable design, the Allstruder supports both novice users and experienced researchers, providing a robust platform for reproducible and high-resolution syringe-based extrusion in scientific, educational, and industrial environments.
