HIOKI E.E. CORPORATION collaborated on mold testing for the use of recycled materials in trade-in measuring instruments.

We collaborated with HIOKI E.E. CORPORATION on their trade-in service initiative to utilize recycled materials by conducting printing tests using ExtraBold's large pellet-type 3D printers, " EXF-12 " and " REX-BUTLER ".


HIOKI offers a "product trade-in service" where they collect measuring instruments that have been used for many years and reuse them as recycled raw materials using disassembly and sorting technologies that are only possible with their own products. On their website, they state that approximately 72% of the collected measuring instruments are reused as recycled raw materials, and they aim to achieve a recycling rate of 97% in the future.

This 3D printing test was conducted as part of HIOKI's initiative to utilize measuring instruments traded in by customers as recycled materials. ExtraBold used the large pellet-type 3D printers " EXF-12 " and " REX-BUTLER " to create models to verify new possibilities for the use of the recovered materials.


3D Maysa will be exhibited and sold from May 6th to 12th at Matsuya Ginza 7F, Asobi Gallery 1979.


Recycled materials from measuring instruments are given new value through 3D printing.

To recycle used products, including plastics, as resources, it's crucial to go beyond simply collecting them as raw materials and instead conduct a process that verifies "what uses they can be reused for" and "whether they can function as products or components."

The EXF-12 and REX-BUTLER are large-format 3D printers capable of directly handling a variety of materials, including pellets and crushed materials. They are suitable for pre-production verification using molds, small-lot demonstrations, and exploring the use of recycled and unused materials. In initial verification of circular manufacturing like this project, they can be used as a means to visualize the potential of materials.

This test demonstrates the potential for a circular economy, from the trade-in and collection of measuring instruments to their disassembly, sorting, recycling, and subsequent application to new fabricated objects. This initiative is also being featured on HIOKI's official Instagram account.




Supporting demonstrations of circular manufacturing

ExtraBold has been working on new ways to use resin materials and the reuse of waste and unused materials through the development and provision of large pellet-type 3D printers.

Going forward, we will continue to support demonstration experiments to utilize waste materials, scraps, and recycled materials held by companies not merely as waste, but as "resources for the next generation of manufacturing." Through material evaluation, molding tests, and application studies, we will take concrete steps toward the implementation of a circular economy together with our partner companies.

Please feel free to contact us if you would like to cooperate with us or have any questions regarding these initiatives.
