Ti64 can be tricky and depending on the setup and parameters of the builds you’re looking at. If the part doesn’t have much time to cool between layers or if you’re operating with a high preheat, you may need to include some relaxation effects like specifying creep properties. Please refer to the verification manual for cases VM-AM-003, VM-AM-004 & VM-AM-005 where double cantilevers have been observed to produce good results. Also, please note that in these VM examples a “Dwell Time Multiple = 5” has been used; i.e., there were 5 of these parts on the build plate so there was more time to cool between layers. An important point to note about material properties provided in engineering data is that the user might have to check the sample properties against what they are seeing coming out of their machines and vary them accordingly. In addition to specifying the stress relaxation effects, parameters such as dwell time, preheat temperature, and variables affecting heat loss to the powder might also become important depending on the material and might need corrections as well. AM process itself is complex, and the results can have a large variation depending on some machine parameters. Hence it is the responsibility of the user to always make sure to validate material properties with the as-built properties from the specific machine/parameter set in order to expect accurate results in terms of distortion magnitude. It is worth keeping in mind that the variations in properties might be better controlled/determined using the Additive Science Product, however, there’s no specific timeline yet for when those capabilities will be available.
