Polypropylene / PP vs PETG: Which Filament Should You Use?
PP is specialised for lightweight, flexible and chemically resistant uses; PETG is usually the more broadly approachable choice.
Choose Polypropylene / PP when
- You need PP-specific chemical resistance or living-hinge behaviour.
Choose PETG when
- You need a general functional filament with easier adhesion.
Side-by-side context
