It brought solar-powered smartphone chargers to the streets of NYC, now Pensa, a Brooklyn-based design firm, is taking on desktop prototyping. Its latest invention, DIWire, is a compact CNC wire bender. A machine designed solely to bend wire clearly has its limitations, but DIWire was actually born from the limitations of more versatile technologies. The team traditionally used a 3D printer to build furniture models, but found that the resulting models didn't stand up to testing. With tiny broken chair legs as inspiration, Pensa set out to make an accessible machine that addressed the laborious nature of hand-bending and the impracticality of mass-production wire bending.
