PETG vs Nylon
PETG is the easier choice for everyday functional parts; nylon is tougher and more wear-resistant, for gears, hinges and bushings, but it must be dried before printing and strongly prefers an enclosure. On price, PETG is the cheaper today: an established 1 kg spool costs a median of £14.43 per kg, against £27.22 for Nylon. We track 1,354 PETG and 59 Nylon listings. The cheapest single listings are £5.63 per kg (PETG) and £16.59 per kg (Nylon).

£14.43 | £27.22 |
| Ease of printing | Fairly easy: a little harder than PLA, and it strings more | Demanding: must be dried before printing, and is reluctant to stick to the bed |
| Heat resistance | Medium: holds up to around 75°C | High: above PETG, varying with the grade |
| Enclosure needed | No | Strongly preferred, to limit warping |
| Typical uses | Functional parts: brackets, hooks, planters and outdoor fittings | Gears, hinges, bushings and hard-wearing mechanical parts |
| Main drawback | Strings more than PLA | Absorbs moisture from the air, so drying is not optional |
Prices are per kilogram of filament, with multi-spool bundles counted at their full weight, and are read from Amazon UK several times a day. The median is the middle listing among established 1 kg spools (new, with 100 or more reviews): half cost less per kg, half cost more. Little-known listings are left out of it because they are priced far higher and rarely bought; the listing counts and the cheapest figures cover everything we track.
Which should you buy: PETG or Nylon?
Buy PETG for brackets, mounts and general functional parts: it is strong enough for most jobs and prints on any machine. Buy nylon when the part slides, meshes or flexes repeatedly, and only if you are set up to dry the spool and print from a dry box. Nylon also needs an all-metal hot end.
