Cheapest PETG filament in the UK

PETG sits between PLA and ABS: tougher and more heat resistant than PLA, but still printable without an enclosure. SpoolDeal follows 589 PETG listings on Amazon UK, Eryone UK and SUNLU UK and re-checks them through the day, so the prices on this page reflect what you would actually pay at checkout rather than a cached snapshot. The cheapest PETG listing we are tracking right now is £7.59, which works out at £6.76 per kilogram. 96 of those listings are at least 5% below their usual 90-day price right now.

PETG is best suited to functional parts, brackets, outdoor items, food-adjacent containers and anything that needs a little flex before it breaks. As a starting point, print PETG at 230–260°C with the bed at 65–85°C; an enclosure helps on big parts. Finished parts hold their shape to about 69°C. Use a glue stick or PEI-safe release on smooth beds — PETG can bond hard enough to chip glass. Dry PETG if it has been out for a few days or starts stringing: 65°C for about 6 hours, and no hotter than 70°C.

When you are comparing PETG deals, the headline spool price is rarely the whole story. Reel weights vary between 500g, 800g and 1kg, and multipacks are often listed at a bundle price that looks expensive until you divide it out. Every card below shows the price per kilogram alongside the current price so you can compare like for like, and we flag listings that have recently dropped so you can tell a genuine discount from a permanently inflated "was" price.

Brands currently stocked in this category include ERYONE, TINMORRY, SUNLU, OVERTURE, ANYCUBIC, GratKit. Prices between brands can differ by more than 50% for functionally similar filament, so it is worth checking a few before committing to a bulk order.
