Workshop Jigs are specialized tools or guiding systems designed to control, position, support, or guide workpieces and cutting tools during fabrication operations. In digital fabrication workflows, workshop jigs are commonly produced using CNC Routing, Laser Cutting, precision machining methods, and modular fabrication systems.
Digitally fabricated jigs improve manufacturing accuracy, repeatability, efficiency, and operational consistency across fabrication environments.
Workshop jigs are widely used in woodworking, machining, assembly operations, prototyping, and digital fabrication workshops.
