Pros and cons

Pros

  • Designed to dry filament while the AMS continues printing, potentially avoiding a separate drying step for multi-day or multi-colour jobs.
  • The claimed four-spool capacity and dual airflow make it relevant to users running several filaments in one Gen 1 AMS.
  • The lid-replacement installation is described as non-destructive and tool-free.

Cons

  • Compatibility is restricted to Bambu Lab AMS Gen 1. The listing excludes AMS Lite and other AMS versions or brands.

What to know before buying

Listing details to confirm

Listing details are inconsistent about dimensions and weight: one set gives 36.3D x 27.8W x 13.1H centimetres, while another gives 27 x 13 x 36 cm and 2.59 kg. A separate manufacturer block lists 1.7 kg net and 2.3 kg gross, so confirm the dimensions and weight for the selected listing. The title's 70°C in 20 minutes is a heating claim, not an independently established result.

Who is it for?

A good fit for

  • Bambu Lab AMS Gen 1 owners who want to dry filament while printing.
  • Multi-colour or longer print jobs where having several spools available in one AMS is useful.

Less suited to

  • Owners of AMS Lite, another AMS generation or another brand's automatic material system.
  • Buyers who need a standalone filament dryer rather than an AMS lid upgrade.

Customer feedback reports positive experiences with operation, print quality, fit and installation, including a reported fit with the Bambu X1C AMS. Temperature control receives mixed feedback. For Gen 1 owners, those reports make fit and ease of fitting relevant positives, while temperature-control variability matters if precise drying settings are important. These are customer perceptions, not performance verification.

Positive themes

  • Customers report improved print quality and consistent operation.
  • Customers describe an easy installation and a good fit with the Bambu X1C AMS.

Mixed feedback

  • Customer feedback is mixed on temperature control.
