Bambu Studio Update 2.5.0 Sees Better Support Interfaces and Remote AMS Drying

The most practical change for multi-material users is an overhaul of the prime tower when mixing PLA and PETG in a given print. These two materials typically resist bonding, which is what makes them great as complementary support materials. The flip side of this is that it often leads to messy prime towers with poor layer adhesion, sometimes leading to print failure. Bambu Studio 2.5.0 addresses this by introducing a suite of parameters – accessible only via Developer Mode, toggleable in the software’s preferences menu – that boosts interface-layer temperatures to the material’s maximum and implements pre-extrusion paths to stabilize pressure before the nozzle touches the tower.

For those running the new AMS 2 Pro or AMS HT, the “Device” page in Bambu Studio now includes remote drying controls. Users can trigger a drying cycle directly from the slicer, even during an active print, though the system will automatically throttle drying temperatures to avoid overheating the internal electronics while the motors are engaged. Accessing this requires firmware version 01.02.30.00 (currently only stated for the H2D) – you should verify local firmware availability before attempting remote operation.

VFAs Be Gone

Surface quality receives an experimental nod through two new features: Consistent Surface and Short Travel Acceleration. These are aimed squarely at vertical fine artifacts (VFA), subtle visual artifacts common on machines running at high speeds, particularly when using glossy filaments. Consistent Surface prioritizes steady outer wall speeds by absorbing speed fluctuations in the infill, while Short Travel Acceleration applies a gentler 250 mm/s² limit to brief moves. These settings also sit behind the “developer mode” wall, so be sure to toggle that on before you go looking.
