# 3D-Printed Childcare Walls Woh Hup 3D Prints Childcare Centre Exterior Walls By Kanesa David | Written with AI assistance | Published 2026-03-25 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/woh-hup References: [3dprint](https://3dprint.com/324424/singapore-3d-prints-childcare-center/) & [wohhup](https://www.wohhup.com/) A construction team led by Woh Hup used large-scale 3D concrete printing to produce the exterior walls of a childcare centre in Singapore, with the first story printed in two days featuring sensor-monitored, cast-in-place concrete. The project involved partners including the [National University of Singapore](https://www.trendhunter.com/trends/unnatural-history-museum-of-singapore), the [Building and Construction Authority](https://www.trendhunter.com/trends/building-block-etc) and the [National Additive Manufacturing Innovation Cluster](https://www.trendhunter.com/trends/ignacio-prego-architectures) and was built as part of a 348-unit condominium development in Woodlands. The printed walls served as structural elements and underwent compression, bending and shear tests; the process cut labor and manhours versus traditional formwork while technicians monitored on-site concrete quality and used a mix that currently increases cement content. The team is experimenting with up to 60% recycled glass powder in the mix to halve CO2 emissions while preserving strength. For residents and developers, the method promises faster, lower-labor exterior construction, quieter night shifts and greater design freedom for architects, though material-emissions trade-offs remain a focus as the sector scales.
