Guides

Silk filament: how to get the shiny finish
Silk PLA gives prints a metallic sheen, and dual or triple colour silk shifts colour as it turns. What it is, how to print it, and where it falls short.
Bed adhesion: what actually works
Glue sticks, hairspray, rafts, brims and expensive surfaces — an honest ranking of what fixes prints coming loose, starting with the free fix that solves most cases.
Do you need a filament dryer?
Wet filament is real and ruins prints, but a dedicated dryer is not the only answer. How to tell if moisture is your problem, and what to do about it.
Filament storage: dry boxes, vacuum bags and desiccant
Keeping filament dry is cheaper than drying it out. What actually works, what desiccant to use, and why the little sachet in the bag is already spent.
