If you are an aircraft component manufacturer dealing with material imperfections in Ti-6Al-4V alloys — this project developed adaptive multi-laser technology that can reduce defects by ~50% and lower material waste by 10-50%.
Adaptive Laser Technology to Reduce Defects and Costs in Metal 3D Printing
Imagine 3D printing metal parts like using a high-tech glue gun that can change the shape and intensity of its heat beam on the fly. Instead of a static beam, this system adjusts itself in real-time to prevent bubbles and cracks in the metal. It's like having a smart sensor that fixes mistakes while the part is still being built, ensuring the final piece is as strong as a traditionally forged part.
What needed solving
Metal 3D printing often suffers from internal stresses, porosity, and material anisotropy, leading to high scrap rates and inconsistent part quality. These issues make it difficult for additive manufacturing to compete with traditional methods in high-volume industries.
What was built
An adaptive multi-laser-beam system with real-time monitoring (multi-spectral imaging and thermography) and physics-based models to control the melt pool.
Who needs this
Who can put this to work
If you are a marine engineering firm dealing with distortions and internal stresses in large metal parts — this project developed closed-loop control and beam shaping that can lead to 10-33% in cost savings.
If you are a vehicle parts supplier dealing with slow production speeds and high scrap rates — this project developed a system that can increase process productivity by up to 100%.
Quick answers
How does this technology impact production costs?
The project aims for 10-33% in cost savings through increased productivity and energy savings.
Can this be used for mass production at an industrial scale?
Yes, the technology is being tested across three sectors ranging from low-volume high-value parts to high-volume low-cost production.
Who owns the intellectual property and how is it licensed?
Based on available project data, the sub-technologies developed in the work packages will be commercialized, while end users will integrate the technologies into their processes.
How does it improve the quality of the final product?
It reduces porosity and defects by ~50% by adjusting the laser beam temporally and spatially during the build process.
What is the environmental impact of implementing this system?
The project projects a reduction of 5 million tons of CO2 emissions per year and a 15% reduction in greenhouse gases.
Who built it
The consortium is heavily industry-driven with a 54% industry ratio, comprising 7 industrial partners and 5 SMEs. This strong commercial presence, combined with 4 research centers and 1 university across 7 countries, suggests the project is focused on market application rather than pure theory, specifically targeting the aerospace, maritime, and automotive supply chains.
