# Programmable Foam Lattice Systems EPFL Unveiled The Programmable Lattice By Grace Mahas | Written with AI assistance | Published 2026-03-05 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/programmable-lattice References: [3dprinting](https://3dprinting.com/news/epfl-researchers-develop-programmable-lattice-structure-for-robotics-using-single-foam-material/)  Researchers at [EPFL](https://www.trendhunter.com/trends/High-durability-printable-materials) introduced a [3D-printable programmable lattice](https://www.trendhunter.com/trends/aeris) made from a single foam material, designed to replicate a range of biological tissue properties. The system uses configurable unit cells—principally body-centered cubic (BCC) and X-cube types—allowing continuous blends of stiffness and load-bearing behavior within one printed part. The team published the work in Science Advances and demonstrated the approach in July 2025. The lattice lets designers vary cell shape, orientation and position, and to superimpose cells to expand the design space; four superimposed cells produced about 4 million configurations and five cells yielded over 75 million. EPFL built an elephant-inspired robot that combined a soft, twistable trunk with stiffer hip, knee and foot joints, showing the method’s range. The open foam geometry also offers high strength-to-weight ratios and compatibility with fluid environments. For consumers and makers, the lattice promises lightweight, tunable robotic parts that merge soft and rigid functions in one print, reducing assembly and material switches. Its capacity to embed sensors or other materials suggests clearer paths to adaptive, musculoskeletal-like robots and fluid-capable devices.
