The Enactus UWA Design Challenge invites university students across Australia to help shape Australia’s first recycled thermoplastic 3D printed tiny home. This is not just a concept challenge. Students will contribute ideas to a real circular construction project exploring how recycled polymer recovered from decommissioned subsea infrastructure in the oil and gas industry can be transformed into compact, liveable housing. Enactus UWA is working with Hyperion Systems, a Western Australian large-format additive manufacturing startup, to explore how standout ideas from the challenge could help move the project toward a real built outcome. Participants will design a tiny home on wheels for a regional Australian setting, using the unique possibilities of large-format 3D printing to create forms, layouts and features that traditional construction cannot easily achieve. Strong submissions should be creative, modern, feasible to print and genuinely liveable, while making smart use of a compact footprint. Students from any field are welcome. This is an opportunity to build a standout portfolio piece at the intersection of emerging construction technology, sustainable materials and forward-thinking housing design, while competing for a share of a $1,500 prize pool. Submissions will be assessed by a judging panel expected to include representatives from Enactus UWA, SONA WA, Woodside Energy, Hyperion Systems and other contributors connected to the project. Winning and standout submissions may also be showcased to industry partners and considered as the project develops. Full details, submission requirements and judging criteria are available in the Enactus UWA Design Challenge Brief, accessible after registering.
