For Bambu Lab owners
You already own the printer. The question is whether the filament has to come from the same company. Here is the price per kilogram against Bambu Lab's own store, the spool measured against the window they publish, and the source limitations behind each figure we quote.
Compared against the cheaper of Bambu Lab's two forms for each material, so refills are matched against refill pricing rather than against the more expensive spool.

All rows are 1 kg net, USD, single unit at list price. Bambu Lab figures were read from the product pages linked above on 2026-09-06; their pages also show a lower headline price for orders of ten or more, which is not what a single spool costs. Our own volume price is the 4+ column, applied automatically to any mix.
TPU 95A HF: No refill version is sold.
This is the question that actually decides the purchase, and it is a measurement rather than an opinion. Bambu publishes a spool window; ours is inside it.

Limits quoted from wiki.bambulab.com, read 2026-09-06. Flexible TPU is the exception on both feeders: see the TPU guide for what goes where. Per-machine detail is on the printer pages: A1, A1 mini, P1S, P2S, H2D.
A comparison with nothing in the other column is not a comparison.
