PLA vs PLA+
PLA+ is a toughened PLA blend: it prints much the same as standard PLA and is less brittle, but there is no agreed standard behind the plus and it does not raise the heat limit of about 55°C. On price, PLA+ is the cheaper today: an established 1 kg spool costs a median of £14.25 per kg, against £15.99 for PLA. We track 4,021 PLA and 1,047 PLA+ listings. The cheapest single listings are £6.39 per kg (PLA) and £6.13 per kg (PLA+).

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: PLA or PLA+?
Buy standard PLA for display models and anything where price per kilo matters most. Buy PLA+ for parts that get handled, clipped together or dropped, where the extra impact resistance and layer adhesion earn their keep. Compare the two on price per kg before paying a premium: the blend differs from brand to brand, and some PLA+ costs no more than plain PLA.
