What 3D printed material is used for a weldment fixture depends on a variety of factors: How large is the part? How geometrically complex is the part? Is there concern of thermal stress? Is there concern for mechanical stress?

If there are welding locations near the restrained part regions, then a high temperature material like ULTEM 1010 is likely well suited. ULTEM 1010 offers the highest heat resistance of any FDM thermoplastic and the durable nature of the material can increase the lifetime of a fixture.

If there is a concern for mechanical stresses, but not thermal stresses, then an engineering plastic like Polycarbonate (PC) or a standard grade plastic like ASA or ABS could be suitable.
