14Trees printed the walls in 18 hours.
On 21 June 2021, children began classes in a 3D-printed school in Salima district, Malawi. 14Trees, a joint venture of Holcim and British International Investment, built it.
Printed in 18 hours
The school's walls were printed in 18 hours.
The classroom gap
14Trees pointed to a shortage of 36,000 classrooms in Malawi. It said 3D printing could close that gap in about 10 years.
Why it matters
This is a printer pointed at a public need, not a showcase home.
