Cheapest PLA+ filament in the UK

PLA is the easiest 3D printing filament to run: it prints cool, barely warps, and works on any open-frame printer. SpoolDeal follows 604 PLA+ 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 PLA+ listing we are tracking right now is £8.49, which works out at £6.80 per kilogram. 132 of those listings are at least 5% below their usual 90-day price right now.

PLA+ is best suited to prototypes, models, display pieces, cosplay props and anything that will not sit in a hot car or in direct sun. As a starting point, print PLA+ at 205–230°C with the bed at 45–60°C; it doesn't need an enclosure. Finished parts hold their shape to about 54°C. PLA likes strong part cooling and open airflow. PLA+ absorbs moisture slowly; dry it when prints start stringing or popping: 50°C for about 8 hours, and no hotter than 55°C.

When you are comparing PLA+ 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 SUNLU, eSUN, OVERTURE, ANYCUBIC, ELEGOO, ERYONE. 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.
