Cellulose, the most abundant organic polymer on Earth, is found in the cell walls of green plants and various types of algae. Some bacteria are also capable of producing it. However, 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 groundbreaking 3D printing technology that uses cellulose as its primary material. This innovation aims to revolutionize the construction sector by enabling the printing of entire homes, offering a sustainable and eco-friendly alternative to traditional building methods.
A collaborative project called +Project has emerged with strong support from the EU Structural Funds, having raised 17.6 million Swedish kronor (approximately RMB 131.6 million). The project, currently valued at over 35.3 million kronor (around RMB 26.4 million), is led by Sliperiet, a subsidiary of Umeå Arts Campus. This initiative focuses on developing a range of cellulosic 3D-printed materials, with the ultimate goal of constructing houses entirely from cellulose.
According to Marlene Johansson, director of Sliperiet, the project’s core idea is to foster local manufacturing and create an innovative, interdisciplinary environment where companies can collaborate and grow. “This aligns with our broader strategy to build a dynamic ecosystem for creative and technological development,†she explained.
The project primarily targets the wood, construction, design, and decoration industries. Its vision is to produce 3D-printed materials made from cellulose that can be used for everything from walls and window frames to full-scale homes. The project is set to run until early 2018, and if successful, we may witness the first 3D-printed houses made from the most abundant organic material on the planet.
Linnéa Therese Dimitriou, creative director at Sliperiet, noted: “While 3D printing of concrete components already exists, this project brings us closer to the forefront of digital manufacturing and mass customization. It opens up exciting opportunities for the local forest and construction industries.â€
