%X Abstract A 3D-printed metal solid target using additive manufacturing process is a cost-effective production solution to complex and intricate target design. The initial proof-of-concept prototype solid target holder was 3D-printed in cast alloy, Al¨C7Si¨C0.6Mg (A357). However, given the relatively low thermal conductivity for A357 (¦Êmax, 160 W/m¡¤K), replication of the solid target holder in sterling silver (SS925) with higher thermal conductivity (¦Êmax, 361 W/m¡¤K) was investigated. The SS925 target holder enhances the cooling efficiency of the target design, thus achieving higher target current during irradiation. A validation production of 64Cu using the 3D-printed SS925 target holder indicated no loss of enriched 64Ni from proton bombardment above 80 ¦ÌA, at 11.5 MeV. View Full-Tex
