"Unlike the use of robotics to improve productivity, safety, and quality in construction, 3D printing does not follow the conventional processes of laying bricks. “Layered construction” has become a completely new alternative technology in the construction industry. Plus, construction sites are changing. Instead of building work being carried out entirely on-site, structural modules are increasingly prefabricated under industrial and automated conditions and assembled on-site, saving time and cost for better quality.
3D concrete printing technology is in use today for homes, architectural features, and construction projects from wells to walls. Proponents say it has the potential to significantly disrupt the entire construction industry if it can get over a few hurdles first."*- does 3D Printing has a similar potential in underground construction? Can we defeat these hurdles?
We organised a Workshop focusing on the 3D Printing in Underground Construction to clear this up.
The main questions of the workshop were:
- What kind of elements in underground construction could be 3D printed of concrete?
- What is the potential for 100% 3D printed elements?
- Which use cases would be interesting for using 3D print as lost formwork or for the combination with other technologies?
- Is it possible to add openings, fixings, anchors, or other elements?
- Sustainability issues around 3D printed elements (material, fabrication, logistics,…)
- Are the new materials for 3D printing that would replace concrete, or new components for this specific sort of concrete production?
