The Gadgeteer tested the xTool O1 Omni UV flatbed printer by curing white and textured ink onto an unconventional canvas: a dried, spent espresso puck. While the machine successfully deposited legible, raised artwork onto the coarse grounds, the author reported the resulting item is fragile and intended strictly for display. xTool explicitly warns that UV-printed surfaces are not food-safe, and official workflow guidance focuses on standard substrates such as wood, paper, and acrylic rather than experimental organic materials.
