Love is Love, Rainbow Love-ly dragon! I used iSANMATE PLA+ with rainbow gradient. The gradient changes very slowly so I think this configuration works very well with this filament and tiny objects to get this multicolor PLA effect: infill 100% or/and concentric infill type (to get the rainbow effect!), no support (but you can add supports to get more colors), brim enabled + glue on the plate (I use eco-friendly water-based spray glue). Print speed: 100mm/s, initial layer speed 60mm/s. Printing temp: 220 °C MAX!! Build Plate temperature: 45 °C. Layer Height: 0.10 m with a 0.4 nozzle. Slicing software: Creality Print. Printer: Creality K1 Max.
