Additive manufacturing ("AM" or "3D printing") has become a powerful tool for rapid prototyping and manufacturing of complex geometries. A 433 MHz IH-DTL cavity has been constructed to act as a proof of concept for additive manufacturing of linac components.

A new linac for the NICA ion collider is under con-struction for JINR at BEVATECH GmbH. As first cavity the 2.5 m long RFQ was manufactured. Within this length it accelerates particles with a mass to charge ratio up to three to an energy of 600 keV/u. The operation frequency is 162.5 MHz and the 4-Rod structure consists of 23 RF cells that need to be adjusted using tuning blocks in order to provide the required field distribution along the electrodes. The status of the manufacturing and the upcoming tuning process including the overall RF setup of the RFQ are summarized in this paper.

Additive manufacturing ("AM" or "3D printing") has become a powerful tool for rapid prototyping and manufacturing of complex geometries. A 433 MHz IH-DTL cavity has been constructed to act as a proof of concept for additive manufacturing of linac components. In this case, the internal drift tube structure has been produced from 1.4404 stainless steel using 3D printing. We present the concept of the cavity as well as first results of vacuum testing and materials testing. Vacuum levels sufficient for linac operation have been reached with the AM linac structure.
