“We can get results 20x, 30x, even 50x faster with nTopology. Before, we only had enough time to produce one design; with nTopology we can have more variations and test them a lot faster.”
Lead Engineer, Lockheed Martin
“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.
“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.”
Amos Benninga, LightForce Orthodontics
“Nothing is more valuable than seeing what you are doing while you are doing it! Any effort that brings down the visualization time for more seamless interaction with complex models is genuinely priceless.”
Onur Yüce Gün, New Balance
