Designed by artist and engineer Jacob Eldred, a Yale University Engineering graduate, using CNC and LMM techniques, this ceremonial mace caught our attention because it combines traditional and additive manufacturing techniques.
While CNC was used as the traditional technique, the AM process utilised as part of the production was Incus’ lithography-based metal additive manufacturing (LMM) technology solution.
Jacob Eldred comments: “As an artist and engineer, I am fascinated by the re-emergence of flowing, natural forms in contemporary manufacturing. Wood, stainless steel, aluminium, brass and copper were used for their unique properties and symbolic meaning.
The design represents the interdisciplinary nature of engineering learning and collaboration. The ceremonial mace's intricate design is a result of complex design features and manufacturing methods. The fluid form created through additive manufacturing represents advancements in engineering from hand and machine manufacturing to modern 3D printing.
What is so special about a ceremonial mace?
The ceremonial mace has a hand-carved wooden base and an intricate shape made using CNC and LMM techniques. The stainless steel 316L section at the top of the structure was printed by Incus Hammer Lab35. The piece symbolizes a tree splitting into branches.
Its complex curves and internal geometries could not have been achieved by machining or casting; its natural flowing form was created using 3D printing. The piece evokes the exquisite silver, ivory and wood craftsmanship of Vienna and Dresden.
This simplifies machine handling and print job preparation. Incus' Hammer Lab35 offers complete design freedom whilst enabling manufacturing control for complex geometries.
