A brand new analysis mission exhibits how 3D printing and machining can lastly work in sync. Led by researchers on the Vienna College of Know-how in Austria (TU Wien), the mission goals to plan and optimize each step of hybrid manufacturing, from 3D printing to machining, earlier than manufacturing even begins.
A staff of engineers from TU Wien’s Institute of Manufacturing Engineering and Photonic Applied sciences (IFT) developed smarter methods to mix additive and subtractive manufacturing (or machining) processes in a single, streamlined workflow. If executed proper, this hybrid manufacturing can save time, reduce prices, and scale back waste, particularly in factories that make giant or advanced elements.
3D printing and machining, which are sometimes handled like two separate worlds, will be introduced collectively in a manner that’s really sensible for producers.
From Metallic Wire to Completed Half
The analysis centered closely on Wire Arc Additive Manufacturing (WAAM), a way used to 3D print giant metallic elements utilizing welding wire. WAAM is right for creating large, heavy-duty parts, however these elements nonetheless must be milled or smoothed out afterward. That’s the place issues typically get difficult and costly, the consultants clarify.
In keeping with the staff, they discovered methods to foretell how every 3D printed half would behave earlier than printing even begins. Utilizing digital simulations, they may estimate how the half would shrink, the place it would warp, and the way a lot materials would must be eliminated.
In addition they examined machine hammer peening, a way that smooths and strengthens the floor of a printed half earlier than it’s machined. They mixed it with different remedies like shot peening, which makes use of small metallic balls to toughen the floor, and Hirtisation, a chemical course of that removes tough edges and leftover powder. The mixture led to extra uniform and sturdy elements.

IFT’s large contribution was a simulation mannequin that helps factories plan printing and machining prematurely. This contains calculating how a lot additional materials must be printed to permit for ending, the place stresses or tough spots may seem, and machine the half extra effectively afterward. The result’s much less materials waste, shorter machining time, and fewer surprises.
Making It Work for Small Producers
Whereas hybrid manufacturing sounds high-tech, the mission was designed with small and medium-sized firms (SMEs) in thoughts. Many of those companies are thinking about 3D printing however don’t have the sources for sophisticated workflows or costly high quality management setups.
The IFT staff labored instantly with 15 Austrian firms to check and validate real-world functions, ensuring the instruments they developed might really be utilized in day-to-day manufacturing facility settings, together with approaches for the seamless integration of WAAM processes into present manufacturing strains. The purpose was all the time to make hybrid manufacturing extra inexpensive, scalable, and sensible.

One other a part of the mission centered on creating a wise software program system that may modify how machines transfer based mostly on real-time sensor knowledge. This method, described as a CAM rule engine, is linked to a central database that collects info from each step of the manufacturing course of. Collectively, they assist factories transfer nearer to totally automated, data-driven manufacturing.
A Staff Effort Throughout Europe
This work was half of a bigger worldwide effort known as Superior Processing of Additively Manufactured Elements – Part II (Advert-Proc-Add II), a analysis mission centered on enhancing how 3D printing and machining work collectively in actual manufacturing facility settings. The mission introduced collectively groups from Austria, Germany, and Belgium, together with universities, trade teams, and analysis institutes. Companions just like the Institute for Machine Instruments on the College of Stuttgart, the Institute for Machining Know-how at TU Dortmund, and KU Leuven in Belgium all contributed to creating hybrid manufacturing quicker, smarter, and simpler to undertake.
What’s extra, trade teams just like the ecoplus Mechatronics Cluster and Analysis Affiliation for Mechanical Engineering (FKM) in Germany helped flip the analysis into actual instruments that firms can really use of their factories.
It was funded by nationwide innovation businesses from every nation, with robust backing from Austria’s Analysis Promotion Company and Germany’s Ministry for Financial Affairs and Local weather Motion.
This mission proves that 3D printing and machining can work collectively in a better, extra sensible manner, in order that 3D printing just isn’t remoted from the remainder of the manufacturing facility ground. In the long run, it’ll assist join additive and subtractive processes, making them usable for on a regular basis producers.
The findings can be introduced on the World Machine Instrument Exhibition (EMO) 2025 in Hanover, one of many world’s largest commerce gala’s for industrial manufacturing.
