BeAM News BeAM machines to integrate In-Process Standoff Distance control in partnership with Precitec and Siemens
Strasbourg, Gaggenau, Nüremberg – November 15th, 2019 – The standoff distance sensor will be presented at Formnext, the leading global exhibition and conference on additive manufacturing, which takes place on November 19-22, 2019 in Frankfurt.

Directed Energy Deposition (DED) is an Additive Manufacturing (AM) process where focused thermal energy is used to fuse materials by melting them as they are deposited with a nozzle.
A key process variable is the standoff distance between the part and the nozzle tip, which defines the optimal spot for the laser and the powder to form a stable layer. Controlling this distance allows the system to compensate for any deviation of the other process variables, to simplify the programming and to make the process even more robust.
Precitec has pioneered adapting Optical Coherence Tomography (OCT) to laser material processing as innovative sensor technology. The unique feature of this approach is that process light and radiation does
not disturb the measurement process unlike other imaging technologies. By adapting this sensor to DED processes where the particle stream is transparent enough to quickly and accurately measure the nozzle standoff in μm resolution enables control of the deposition process.
Deposition without/with standoff distance control
Initially developed for welding applications, this technology has been further expanded for Directed Energy Deposition in the frame of the PARADDISE collaborative project funded by the EU. BeAM is the first AM machine manufacturer to integrate this sensor in its machines, which are already equipped with Precitec optical heads and Siemens Sinumerik 840D sl or the new Sinumerik One CNC for class-leading machine automation.

Thanks to the support from Precitec and Siemens, BeAM will integrate and adapt the control cycle that reads the standoff distance from the sensor and keeps this value constant in a closed-loop control by varying the deposition speed with high frequency.
This feature will be available in the BeAM machines in 2020 to process non-reactive as well as reactive materials.
BeAM, created in December 2012, is a pioneer in designing and producing industrial metal additive manufacturing machines using the DED technology (Directed Energy Deposition). BeAM works closely with its customers and business partners to develop and industrialize manufacturing and repair processes with feasibility assessments, pilot production, sales of systems, training and technical support. BeAM is headquartered in Strasbourg, France and has two Solutions Centers, one in Cincinnati, Ohio and one in Singapore. This global presence of engineers trained by BeAM contributes to accelerating the adoption of its innovative technology, while offering engineering services for local industrial companies.
In June 2018, BeAM joined the AddUp Group, a manufacturer of 3D printing machines and production lines based in Clermont-Ferrand. AddUp is a joint-venture between Fives and Michelin, which employs more than 380 people.
