After a successful pilot program in 2016 with around twenty schools, fifty South Australian schools undertook the Makers Empire Learning by Design Course, a ten-week blended professional development program for districts and clusters of schools. Designed to engage students in STEM using 3D technology, the 3D Printing in Primary Schools project is a joint initiative between Makers Empire, the Department for Education (South Australia) and public primary schools in South Australia. This innovative project equips teachers from primary schools with the tools, resources and support to teach Design Thinking, STEM and 21st-century learning skills using 3D design and 3D printing.
