For my part, I'm sure I'll eventually submit data for various flavors of BASF Ultrafuse since it's what I mostly use for clients. The smaller build volume is driving some creative nesting for the requisite witness coupons & tensile bars, but the high print speeds more than make up for the small volume. In the meantime, I can say that the metal filaments do work on the #BambuLab X1, just not in the AMS due to their abrasiveness & brittleness.
