Selective Laser Melting System (SLM) for in-situ sample environment on a synchrotron beamline
Goal of the project:
Establishment of an in-situ sample environment for selective laser melting (SLM) of thin-walled components on a synchrotron beamline at DESY - under measurement conditions.
The financing of this system is dependent on subsidies, it is therefore limited in its total value and requires an acceptance of the system and completion of all agreed service elements by December 17, 2021 at the latest. If the budget is exceeded, the right to cancel is reserved in accordance with § 63 VgV.
procurement
SLM laboratory system with specific installation space adaptation for the implementation and analysis of additive building processes within the PETRA III HEMS beamline (main and side station) and outside at the Helmholtz-Zentrum Geesthacht, center for material and coastal research, in Geesthacht.

Structure as an open system architecture with:
1. good accessibility,
2. Possibility for flexible extensions or modifications with regard to technical components,
3. software functions freely programmable by the customer,
4. Complete integration and synchronization with the beamline control for real-time synchronization of all measurement data generated by the built-in measurement and analysis units. In particular, synchronization with the Debye-Scherrer diffraction data recorded by the measurement detector is required.
Usable alloy powders of the alloy classes (origin (manufacturer and manufacturing process) of the alloy powder may not be restricted.)
Aluminum alloys, titanium and titanium aluminide alloys, nickel-based alloys, iron alloys and steels.
The possibility of using magnesium and / or copper alloys are rated as advantageous.
The entire system including the ancillary and auxiliary units must be able to be set up and operated in a defined installation space.
