ExtraBold Acquires Patent for Revolutionary Collaborative Robot 3D Printer Structure

ExtraBold Secures Patent for Innovative 3D Printer Technology



In a significant development in the realm of additive manufacturing, ExtraBold, a Tokyo-based startup, has announced that it has received Patent No. 7800928 for its novel collaborative robot-based pellet-style 3D printer, the REX-BUTLER. This patent, achieved on January 7, marks a crucial milestone as it is the world’s first of its kind related to the fundamental structure of collaborative robot-based pellet-style 3D printing.

Understanding the REX-BUTLER and Its Unique Design



The core concept behind the REX-BUTLER employs a fixed 3D print head that utilizes a collaborative robot to dynamically move the build plate. This innovative structure addresses common challenges associated with large-scale 3D printers, such as quality of prints, operational stability, feasibility of on-site implementation, and cost efficiency.
