Sweden develops cellulose 3D printing house technology
Cellulose, the most abundant organic polymer on Earth, is found in the cell walls of green plants, various types of algae, and even some bacteria. While it's a natural and renewable resource, the heavy reliance on wood and wood products in the construction industry has led to significant environmental damage. In response, Swedish researchers are pioneering a revolutionary 3D printing technology based on cellulose, aiming to transform the construction sector by using this eco-friendly material to build houses.
A collaborative project named +Project has emerged, raising 17.6 million Swedish kronor (approximately RMB 131.63 million) from the EU Structural Funds. With a total value exceeding 3,530,000 Swedish kronor (about RMB 26.4 million), the initiative is led by Sliperiet, a subsidiary of Umeå Arts Campus. This innovation hub features maker spaces, incubators, and creative environments. The project’s main goal is to develop 3D-printed cellulosic materials, with the ultimate aim of constructing entire homes using cellulose.
“Creating a technology that supports local manufacturing is at the heart of this project,†explains Marlene Johansson, director of Sliperiet. “For us, this initiative is part of a broader strategy to foster collaboration among companies, artists, and innovators in a dynamic, interdisciplinary environment.†The project focuses on industries such as woodworking, construction, design, and interior decoration, with the vision of producing everything from walls and windows to full-scale homes using cellulose-based 3D printed materials.
The project is scheduled to run until early 2018, coinciding with the World Expo. If successful, we may soon witness the first 3D-printed houses made from the most abundant organic polymer on the planet.
Linnéa Therese Dimitriou, creative director at Sliperiet, adds: “There are already technologies for 3D printing concrete parts. Through this project, we’re pushing the boundaries of digital manufacturing and mass customization. This opens up exciting opportunities for the local forest and construction industries.â€
