ReSchool Ukraine develops fast-build 3D-printed educational centers to support reconstruction in war-affected regions. Traditional construction is too slow and labour-intensive to meet urgent educational needs. Our modular 3D-printed classrooms can be built in 3–4 weeks, using 60–70% less onsite labour and lower-carbon materials. In 2025, we aim to launch three pilot projects with municipalities and NGOs, validating a scalable, sustainable model for rebuilding safe learning environments across Ukraine.
