About Paper:

This research is done for the future high luminosity upgrades for the Large Hadron Collider (LHC) at CERN. Various 3D printing methods are tested to address defects in the Dry Gas Injection (DGI) tubes used in the Inner Tracker Support Tube (ITST) of the Compact Muon Solenoid (CMS) detector at the LHC. The DGI tubes will undergo immense radiation, heat, and pressure; therefore, structural integrity is vital. Currently, only 25% of our tubes per print are suitable for use at CERN. A review of 3D printing literature yielded several possible causes for the defects, including instability of the z-axis, layer separation, variations in lift and roller speeds, and more. These methods are still being tested to, hopefully, significantly reduce the time required for DGI printing and to increase the percentage of usable tubes per print. Keywords: [no keywords provided]
