Through digital fabrication, this traditional timber architecture has been brought back to life.

3,500 hours, 50 kilograms of filament, 11,534 individual parts. Maker Mu Yaoguang used 3D printing with PLA‑wood composite material to create a scaled‑down replica of the Temple of Heaven’s Hall of Prayer for Good Harvests.

Mu Yaoguang, a native of Shanxi province, jokingly calls himself a “cyber carpenter.” He is obsessed with mortise‑and‑tenon joinery and has a deep love for the texture of wood grain. Beyond replicating classic buildings, he also designs and prints octagonal pagodas, wooden lamps, and various Chinese‑style ornaments – aiming to infuse the essence of ancient architecture into everyday objects.

The sweeping eaves, intricate bracket sets (dougong), and balustrades of ancient Chinese buildings are all complex curves and precise interlocking structures. Digital modelling allows these architectural forms to be broken down into individual components, while 3D printing ensures that every bracket is accurately formed – making it especially suitable for the physical reproduction of nail‑free joinery like mortise‑and‑tenon.

Wood is the soul of ancient architecture, so the replica material must not only print well but also convey the warm, tactile quality of real timber. Mu chose eSUN PLA‑Wood filament for this project. His assessment: it flows smoothly during printing, with solid interlayer adhesion; under the strain of long continuous prints and the assembly of thousands of parts, its stability never faltered. What surprised him most, though, was the surface finish – fine, flat, and pleasantly dull to the touch, without that cheap plastic feel.

From the Hall of Prayer to a growing range of experiments, Mu Yaoguang is using 3D printing as a digital rubbing tool for traditional architecture. Material is never just a medium – it affects the hand feel, defines the details, and shapes the overall aura of the work. As technology lowers the barriers, what truly sets work apart is an unwavering obsession with texture and structure.
