PETG vs ABS
PETG is far easier to print and needs no enclosure; ABS holds its shape to around 100°C against about 75°C for PETG, but it warps badly without an enclosed printer and needs ventilation. On price, PETG is the cheaper today: an established 1 kg spool costs a median of £14.43 per kg, against £17.71 for ABS. We track 1,354 PETG and 284 ABS listings. The cheapest single listings are £5.63 per kg (PETG) and £6.12 per kg (ABS).

| Heat resistance | Medium: holds up to around 75°C | High: holds its shape to around 100°C |
| Enclosure needed | No | Yes, plus ventilation |
| Typical uses | Functional parts: brackets, hooks, planters and outdoor fittings | Enclosures, car interior parts and prints you want to vapour-smooth |

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 ABS?
Buy PETG unless you have a specific reason not to: it covers most functional parts on any printer. Buy ABS only if you have an enclosed printer and somewhere ventilated to run it, and the part needs to survive around 100°C or be vapour-smoothed. For outdoor parts at that temperature, ASA is usually a better pick than ABS.

Enclosed vs open-frame 3D printers: do you need an enclosure?
An enclosure matters enormously for ABS and ASA and barely at all for PLA. What a printer box really does for warping, fumes, noise and safety, and when an open frame is the better choice.
