voxeljet AG and Parastruct GmbH have successfully tested the 3D printing of recyclable residual materials from the construction industry. The project utilized voxeljet’s binder jetting 3D printing technology with Parastruct’s Ecomould material set.
Ecomould, comprising biogenic production residues and a mineral binder, demonstrated its potential in producing molded parts suitable for cold casting of concrete and ceramics. The technology aims to address excess material recycling in the construction industry, aligning with increasing corporate sustainability goals.
Parastruct’s approach integrates 3D printing to reintroduce unused mineral materials and biogenic resources into the value creation process, offering a sustainable solution for mold making. The market for excess material recycling is projected to grow, driven by legal obligations and Corporate Social Responsibility (CSR) strategies.
Beyond environmental benefits, companies adopting Ecomould can realize significant cost savings by eliminating disposal expenses for construction waste and wood. The technology aligns with sustainability goals, presenting a lower CO² footprint compared to traditional sand-phenolic resin molds.
Ecomould’s versatility extends to its potential for shredding and reusing as particle material in 3D printing. The application of a removable plastic coating further enhances sustainability, reducing the carbon footprint.
voxeljet’s binder jetting 3D printing technology proves ideal for processing Ecomould, offering flexibility in adapting printing parameters. The scalability of results to larger 3D printers, currently available up to 4 x 2 x 1 m, ensures ease of integration into diverse manufacturing processes. The collaboration is currently seeking interested parties to contribute to advancing a more sustainable construction industry, possibly through funding projects.
