SUNLU filament is available here in PLA+, PLA, PETG, PLA Matte, PLA Silk, PLA Rainbow, TPU, PLA Glow. Materials from the same brand usually share spool dimensions and packaging, which makes them convenient for automatic material systems and multi-spool setups, but print settings still differ significantly between polymer types — always start from the temperature range printed on the reel.
Brand pricing on Amazon UK, Eryone UK and SUNLU UK moves constantly: the same SUNLU spool can swing by several pounds within a week as sellers compete, lightning deals appear, and multipack listings rotate in and out of stock. Rather than checking manually, use the price history on each product page to see whether today's price is genuinely low for that item, and set a target price alert so you are told the moment it drops to the number you had in mind.
Every listing below shows the live price, the price per kilogram, and whether the item is currently in stock. Price per kilogram is the fairest way to compare SUNLU against other brands, because spool weights and multipack sizes vary — a cheaper spool is not automatically cheaper filament.
