Abstract

Key motivation behind the combination of superplastic forming and additive manufacturing is to merge
the advantages of two different manufacturing methods. On the one hand the efficiency to form large
scaled parts by superplastic forming and on the other hand additive manufacturing of highly customised
products. While the combination of additive manufacturing with bulk structures is state of the art,
combining sheet metal parts with additive functional elements is hardly investigated. Few research works
have been published regarding additively manufactured functional elements on deep drawn sheet parts.
As forming is limited for Ti-6Al-4V at room temperature and even at moderate temperatures, this paper
presents a new and innovative manufacturing process chain, where superplastic forming and additive
manufacturing is combined to merge the advantages of both. Within this work the possibilities of additive
manufacturing on sheet metal is presented in addition to the numerical simulation of superplastic forming
of Ti-6Al-4V to produce a semi-finished sheet part for subsequent additive manufacturing process. As a
result of this study a LS-DYNA based numerical model is presented for tool development as well as
process simulation for superplastic forming of semi-finished parts which can be utilized for consecutive
additive manufacturing operation.
