Ultra-Lightweight Concrete for 3D printing technologies

About Project
The construction industry still relies on centuries-old processes to manage complex projects. 3D printing with concrete could revolutionise construction. A lot of research on this has been conducted but very little attention has been paid to designing insulation for printed walls. The EU-funded Ultra-LightCon-3D project intends to bridge this gap by introducing the first insulating ultra-lightweight concrete (ULWC) material for 3D printing. This tool will enable the development of 3D ULWC models with optimised mechanical and insulating properties, leading to reduced concrete costs and waste. The project will contribute to the development of energy-saving construction in line with the EU’s Energy Efficiency Strategy.

EU Commission report on 3D printing, places the development of additive manufacturing for construction, in the top 10 future application areas [1]

According to the European Parliament resolution, AM is viewed as “one of the most prominent technologies, with regard to which Europe can play a leading role” [2]
