The first ISO/ASTM 52939:2023 compliant 3D printed social housing project has been completed in record time in Europe. The construction, carried out by Harcourt Technologies Ltd (HTL.tech) in collaboration with COBOD International, sets a new standard in the sector by combining efficiency, sustainability and regulatory compliance.
Social housing built in record time and with efficiency
Located in Grange Close, Ireland, this project includes three semi-detached houses with a total area of 330 m². Using COBOD’s BOD2 3D printer, the project’s walls were completed in just 12 days, and the entire build was completed in 132 days – 35% faster than traditional methods. This time saving reduced costs and demonstrated how technology can optimize every stage of the construction process.
[post_relacionado]What sets this project apart is its adherence to the ISO/ASTM 52939:2023 standard for additive manufacturing. This standard ensures that 3D printed structures meet the same levels of safety and performance as those built using conventional techniques. Both companies, in addition to achieving compliance with these standards, also demonstrated that 3D printing can be a viable solution to address the housing shortage.
Recognition and technological improvements
The project has been awarded the Standards Innovation Award by the National Standards Authority of Ireland (NSAI). Geraldine Larkin, Director of NSAI, emphasised the impact of this construction, highlighting the integration of advanced technologies with strict quality standards. In addition, the company has introduced improvements to its BOD2 printer , such as a larger diameter hose that further reduces printing times.
This development sets a precedent for similar projects in Europe and around the world. The lessons learned at Grange Close can be applied to future developments, accelerating the development of sustainable and affordable housing .
The collaboration between HTL.tech and COBOD has demonstrated that 3D printing can meet market expectations and overcome the limitations of traditional methods, all with a focus on quality and sustainability.
