  • "Every single pound of material you can remove from a spacecraft saves money on launch costs. That’s why we used nTopology to optimize the design."

    James Horton,
    Aerojet Rocketdyne

  • "Using the added benefits of lattices, we can design parts with even higher added value than the shape obtained by pure density-based topology optimization."

    Hiroyuki Nagamoto,
    Yamaha Motor Co.

  • "This product has been hugely successful for us, and this is definitely in part due to the lattice structure that was created by nTopology."

    Beth Stuart,

  • "With nTopology, we were able to create a powerful and unique additive design. It wouldn’t be possible to create such a component with a traditional CAD system."

    Martin Blanke,

  • "Nothing is fast enough for me, but everything is instantaneous in nTopology. I can do the things that are impossible with other design tools."

    Enrique Enriquez,
    KW Micro Power

  • "The models are better, we save a tremendous amount of time on the design process, and we’re able to bring new people up to speed very quickly."
