PLA+ Silk basics: PLA is the easiest 3D printing filament to run: it prints cool, barely warps, and works on any open-frame printer. As a starting point, print PLA+ Silk at 190–230°C with the bed at 35–60°C; it doesn't need an enclosure. The temperature range printed on the reel always wins: it varies between brands and between colours of the same brand.
