In Jinan, China, XISUI Design’s Boulder Park transforms 13,000 square meters into a surreal playscape of 3D-printed concrete boulders.
The park feels both ancient and futuristic, with smooth stone-like forms shaped not by erosion, but by robotic precision.
Children climb, slide, and weave through cavernous tunnels, while quiet nooks and carved seating invite slower moments.
Streams, shading alcoves, and tactile surfaces make the terrain immersive for all ages.
The concrete is stronger than standard mixes, proving that additive fabrication can be playful, safe, and structurally sound.
XISUI sees the project as a glimpse into how 3D printing can shape future landscapes, blending ecology, durability, and imagination. Some of their other playground designs use wood, metal, and recycled materials in fascinating ways, showcasing the breadth of their creativity.
Boulder Park is more than a playground. It is an exploration of how technology can create spaces that feel strangely natural, yet entirely new.
We feel like 3D printed playground design makes a lot of sense, and imagine it will become more common, as older playgrounds are remade around the world.
