3D printing in construction is revolutionizing the sector by addressing the challenges associated with productivity, complex geometry, and performative design. 3D printing also offers the opportunity to introduce more sustainable material such as one from natural or recycled sources. Unfortunately, those materials are non-homogeneous and exhibit complex behavior that usual 3d printing methods struggle with. Advanced AI control software coupled with state-of-the-art IOTsensors and 3D Scanners, can handle the diverse characteristics of natural and recycled materials, resulting in superior quality 3D printed objects.
This new technology will thus support the construction industry’s increasing focus on environmentally friendly practices in the use of sustainable materials (such as soil, ceramics, bioplastics, recycled plastics, recycled concrete or geopolymer), combined with 3D printing’s precision in material usage minimizes waste generation during construction processes, aligning with the EC goal of waste reduction and the long-term sustainability of the construction sector. This technology enables a more sustainable and responsible approach to construction, contributing to a greener future.

The objective of the Q3D: AI Quality control & correction for 3D Printing with recycled and natural materials project is focused on developing sensor and AI robot control technology that can effectively allow 3D printing to work with natural or recycled materials. The solution will involve the integration of a system capable of reading the extrusion process, scanning the produced piece, determining the production issues, and controlling the printing robot to operate at an optimal speed and precision, resulting in high-quality printed objects. The solution is currently in TRL6, and it is the result of over 5 years of development in various research projects driven by industry requests and feedback.

IAAC´s solution directly benefits large-scale 3D printing companies that are interested in expanding the market for printing with new alternative materials. These companies will gain a competitive edge by leveraging our technology to overcome the challenges associated with 3D printing using natural and recycled materials. The development of the technology offers quantifiable benefits that have been demonstrated through objective data obtained from the advancements made thus far, which will foreseeably improve even further with the advances to be developed from now on.

These benefits include:
● Accurate Deposition and Consistent Surface Finish
● Improved Productivity
● Reduced Print Time
● Optimal Material Usage
● Environmental Friendliness
● Improved Product Quality
