esa and DigitalArchi to produce 3D-printed construction formwork from recycled plastic

esa and DigitalArchi have launched a collaborative initiative to manufacture 3D-printed architectural formwork using recycled plastic. The project aims to implement resource-circulating manufacturing within the construction sector.

The initiative utilizes ‘Repla’, a recycled plastic pellet developed by esa through its proprietary ‘esa method’, which allows for the recycling of complex composite plastics that were previously difficult to process and often incinerated. These pellets will serve as the raw material for large-scale 3D printers developed by DigitalArchi to produce concrete formwork and interior/exterior panels.

By combining DigitalArchi’s large-scale 3D printing technology with esa’s recycling capabilities, the partnership seeks to address industry challenges such as labor shortages, material price fluctuations, and the need for CO2 reduction. The technology enables the production of complex shapes and customized components that were difficult to achieve with traditional construction methods.
