Abstract: This study aimed at developing an application and comparison of performance between the two main incremental sheet forming (ISF) variants, single-point incremental forming (SPIF) and two-point incremental forming (TPIF), on a scaled prototype of a biopsy micro forceps (BMF). Experimental tests were carried out initially with the SPIF set-up. Rupture of specimens and low accuracy of them due to bending of the material led to the more complicated TPIF variant. Prior to the physical support tool construction, FEM simulations allowed validating the precision gains. After several adjustments to the tool-path in the new configuration, the BMF was successfully manufactured by TPIF on AA1050-H24 and AISI 304 05 mm thick. Therefore, the presented results demonstrate the feasibility to use ISF for the rapid prototyping of sheet metal medical devices.
