Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- Ready to start manufacturing!
“No specifical tool is necessary to install the part, we just lifted it and put it on the machine table. I took my references on the part and I’m ready to start, just must select my robot program and press “cycle start”.
After 10 hours, the rail is repaired, the built geometries match perfectly with the rail profile. All the data as TCP position, wire feeding speed, laser power, traveling speed are saved during the operation. It guarantees the process according to the qualification parameters and gives us the opportunity to identify any deviation or defect during the deposition. Learning from those data after any manufacturing operation allows us to improve process knowledge and skills and make it evolve.”

AM fast train part 3
The challenge goes on…
Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- It’s time for simulation!
“The CAM part will be simplified due to several advantages of our WLAM process:
- Close to the final dimensions
- High deposition rate possible ➝ beyond 600cc/h
- Low dilution and manageable heat input
- Good mechanical characteristics
Exaggerating a bit, with the right deposition parameters, it will be like generating a path for a 3D printer. Once the building strategies are selected, the parameters filed and the trajectories generated, it’s time to apply some rules to our robots and simulate the operation to avoid any singular point or collision. The part is long (approximatively 2 meters) and the volumes to build are long too, so I generated the toolpath to have the longest deposition tracks and few “off-moves”.
Parameters and toolpath trajectories verified, I can post process my robot program and go back from the numerical world. Rail must now be installed on the machine and repaired!”

Integradde final event
INTEGRADDE FINAL EVENT – The future of European Manufacturing: Enabling Advanced Innovations in 3D Printing
On Tuesday, Mar 14, 2023, the H2020 INTEGRADDE project is holding its Final Event in Brussels (hybrid, format). The event will take place from 09:30 to 14:30 at La Tricoterie. The event is supported by the European Factories of the Future Research Association (EFFRA) and European Association of the Machine Tool Industries and related Manufacturing Technologies (CECIMO).
The conference (which will include different discussions and a networking lunch) will bring together high-level policymakers, industrial actors, research institutions, and other relevant stakeholders to exchange views on the current most compelling issues related to 3D Printing in the manufacturing sector.
This event will offer a networking space for like-minded people within the manufacturing industry while showcasing the latest advancements in Additive Manufacturing, the project’s achievements and upcoming test-before-invest opportunities from related EU projects for technological innovations. The event will also offer an overview on the current and future positing of 3D printing from the perspective of some of the most accredited voices in the industry.
A detailed agenda of the event can be found here.

Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- Preparation is done, let’s make a clean 3D model!
“For the further operations, it’s important to have a clean 3D model with the missing volumes on the part well defined and smooth. Nothing difficult with a CAD software for an advanced designer. We need to extract to worn faces from the STL and “stretch” them to the initial dimensions.
Before any CAM operations, working parameters must be known and the quality of the deposited material checked. To set them, I will do a quick test to identify a window of working parameters with which we get:
- “Good” linkage with the support
- No defect (lack of fusion, crack, porosity, etc…)
- Constant deposit geometry
- Acceptable deposition rate (the key to have a fast operation…)
To check all of this, build samples are cut, polished, and etched to observe them under microscope. It will be also interesting to check to hardness “as deposited”, to identify any deviation from the material datasheet.”

AM fast train part 1
Hello new challenge!
Nathan Mayer, our engineer, takes us on our latest additive manufacturing journey…
- Day 1: first exchanges
“We’re contacted by the company Welding Alloys France, a global leader in the production of advanced welding consumables, automated welding equipment for wear protection, the provision of engineered wear services, as well as wear plates, pipes, and components.
Their issue? They need to repair a worn #railway that has lost its geometry and they decided to go with the laser technology, most precisely additive manufacturing, instead of most conventional technologies.
Today, repairing or rebuilding parts are major players in increasing service times, avoiding waste and reducing carbon emissions. Railways are subject to heavy loads and many cycles; they must be hard and resistant over time and after 28 years, this one has significant missing elements, it is no longer new… To be used again, we must return to the original shape.
Can we really do it? Can we return to its original shape? Is the reconstruction going to be as resistant as the original one? Only time will tell but we’re up for the challenge.”
- Day 2: first reflexions
“Laser metal deposition or the DED additive manufacturing process offer many possibilities and one of them is to be able to deposit on an existing part. Instead of building complete parts, it is possible to rebuild and repair existing ones. Our wireframe laser additive manufacturing (WLAM) process will hopefully be able to help us with the reconstruction and gives back the used railway its original shape.
As for the material for the reconstruction, it must be just as resistant as the original. After a conversation with Welding Alloys France, they tell us they can provide us with the best yarn to fit this application. It is a manganese #steel that hardens on impact. This filler material is commonly used with conventional welding processes, and I think it will be interesting to show the results obtained with our deposition process, using wire and a laser.”
- Day 3: preparation
“As a first step, the rail must be prepared before the repair operation. So, the team starts to gouge and grind, but also learn its geometry by 3D scanning and digital reconstruction. Everything goes smoothly and we’re quite hopeful for what comes next.”
