Bambu Lab Support for PA/PET Filament 1.75mm 500g

The break-away support material for nylon and PET. If you print PA6-CF, PA6-GF, PAHT-CF, PET-CF, PPA-CF or PPS-CF, this is the support Bambu specifies by name — ordinary support materials won't survive the temperatures those filaments run at.

It's engineered to bond weakly with PAHT-CF and PET-CF, forming an interface that peels away cleanly by hand. No dissolving, no soaking, no post-processing — the part is ready as soon as it comes off the plate.

At a glance

Use it with

PA6-CF · PA6-GF · PAHT-CF · PET-CF · PPA-CF · PPS-CF

Bambu name this support explicitly in the data sheet for each of those materials. Using PLA or PETG support with a nylon simply won't work — it will melt or fuse at 280°C+.

Worth knowing

Use PVP glue on the plate, the same as the nylon it supports.

It's a nylon itself, so it absorbs moisture — 1.23%. Dry it at 80°C for 8–12 hours alongside the model filament, and keep it sealed. Damp support prints badly and defeats the point of a clean interface.

Same chamber and bed as the model material, so no compromise needed in the slicer profile.

Not water soluble. If your geometry is enclosed and you can't physically reach the support, you need PVA instead — but note PVA won't tolerate nylon printing temperatures either, so genuinely enclosed geometry in a high-temp material is a design problem rather than a materials one.
