Deng founded
Butlr Technologies along with Jiani Zeng in 2019. Prior to that he was a researcher at City Science Group,
MIT Media Lab. In 2020, his project with Jiani Zeng,
Illusory Material: 3D Printed Optical Textiles was selected "The best experimental design project of 2020" by
Fast Company and won the
2020 Red Dot: Best of the Best, selected from 4170 entries from 52 countries. The same project was also featured by Dezeen as a notable example of 3D-printed design in 2020 and was selected as The Best Inventions of 2021 by
Time Magazine. During
COVID-19 pandemic, Honghao led his team at Butlr to develop sensors to help combat the disease. These sensors are ceiling-mounted to detect body heat and track people's movements indoors. They are thought to help business understand how clients navigate their stores. As of February 2025, Butlr had sold more than 20,000 of it sensors. In 2021,
Wallpaper magazine recognized Honghao Deng as a "Next Generation" talent for his development of "Illusory Material," a 3D-printing framework that uses a multi-layered voxel system to create dynamic optical effects in physical objects. In 2022, he was named to the
Forbes 30-under-30 list. In 2024, he was interviewed by
NYSE. == Publications ==
