Patrick tests whether the xTool O1 Omni can produce a clean UV print directly on fused-filament PLA. He designs a four-inch rounded coaster in Shapr3D, adds pockets for four captured magnets, and exports the model for slicing in Bambu Studio.
The magnet version uses a carefully placed pause so the magnets can be installed before the final layers seal them inside. Patrick also explains the differences between printing a full-size coaster and a smaller fridge magnet, including print time and the importance of keeping magnetic blanks from shifting on the O1 Omni bed.
Three blanks—white, black, and starlight PLA—are scanned and aligned in xTool Studio. The darker colors need a white backing layer, while the white blank can use color directly; masking and layer-order choices prevent unwanted ink from showing around the artwork.
All three UV prints finish in about 18 minutes and use an estimated 24 cents of ink. The results prove the process works, but they also show that layer lines and surface defects remain visible through the ink, making smooth top surfaces, reliable jigs, and sensible batch sizes important for sellable results.
