The CeraStuder is a mechanical paste extruder developed for ceramic 3D printing. It was designed to be used as a modification to existing 3D printer or CNC frameworks, or within purpose-built systems for clay desposition modelling.

In partnership with Amaco/Brent, CeraStruder is being redesigned, documented and published as an open-source hardware project. An early prototype is already available at, as well as at

CeraStruder has been utilized world-wide by artists, designers and researchers in tandem with research in contemporary craft, digital fabrication and architecture.

Learn more about the CeraStruder at its open-source project page, here.

All specialty components of this extruder can be 3D printed in plastic or metal. 3D Model files for these components, along with blueprints and a bill of materials, are available at the CeraStruder open source project website, here.


Amaco/Brent has generously sponsored the research and design to document and publish this platform as open-source hardware. Above are segments from the photo and video documentation for assembly.


Alongside CeraStruder, an extruder controller, "Flow Driver" is in development. This provides a precise and concise means of regulating flow and pressue in the extruder system, and makes it possible to extend existing 3D printer platforms to work with CeraStruder.

Designed with versatility in mind, CeraStruder can be utilized with various purpose-built CNC designs (above) or as a modification to an existing platform (below) such as commercial 3D printers or robotic arms.

CeraStruder was central to the thesis of Carnegie Mellon Masters of Architecture candidate Özgüç Bertug (pictured above). Bertug utilized the extrusion system, along with a Kuka robotic arm, to develop a system for human/machine collaboration in object making.


As CeraStruder is iterated upon and utilized in new contexts, this open source hardware project will continue to grow and evolve.
