Vitro3D Inc., which rebranded as Manifest Technologies in 2025, builds volumetric 3D printing hardware spun out of Bob McLeod's optics and materials lab at CU Boulder. Its Parallax Volumetric Additive Manufacturing (P-VAM) process uses a proprietary light engine and algorithms to cure photoreactive resin simultaneously across three dimensions, forming a complete solid part in one continuous step rather than layer by layer. The company launched a P-VAM Evaluation Kit at RAPID 2025 so engineering and R&D teams can test the process, and sells a modular toolhead intended to drop into existing production lines. Founded in 2020 by Camila Uzcategui and Johnny Hergert, it is seed-stage and based in Boulder, Colorado.
