Description

Is the SUNLU AMS Heater compatible with my Bambu Lab AMS? Absolutely! This heater is designed and optimized specifically for the Bambu Lab AMS (Gen1). We are so confident in its safety that we will provide compensation for your AMS if any damage is directly caused by the installation or use of our product. Will the heat damage my AMS or affect the feed motor? Not at all. Our unique dual-airflow design actively directs heat toward the filament area and away from critical components like the motor. This ensures your AMS operates safely and reliably without the risk of overheating. Does it require extra power? Yes. The SUNLU AMS Heater comes with its own power adapter (included). It operates independently without drawing power from your AMS—just plug and play. Is the lid transparent so I can see inside? Yes! The lid features a strategically placed transparent window, allowing you to easily monitor your filament and the heater's operation without removing the cover. What if I have issues? What kind of support do you offer? Your satisfaction is our promise. We include 1 year of free repair or replacement service for this product, supported by ongoing technical assistance.

  • Worth it!
So many settings, user friendly, great upgrade for my ams. Improved printability of my filaments after drying and gives little work left for the dessicants. Barely any noise when running. Great value, but would just get an AMS 2 pro

  • Highly recommend
I have 1 on each of my ams units. At first I would use the timer function and set it for the max to keep it running. I found out this would cause the tape holding the end of the spool to loosen and mess up at the end of a roll. After getting an error on one of the units for a thermistor, I had it warrantied and replaced. Since then I have left them set on the RH% setting and set the percentage I wanted. They only come on when needed now and I feel this is the best way to use them. Since install, I have noticed a difference in the print quality with reduction of issues that I was having. They aren't loud at all either. Sometimes I forget they are even running. They fit nicely and assembly wasn't hard at all either. I honestly love the squared off look and appearance as well. ... show more

  • Quiet and so convenient! Beats all other dryers since you can dry and print at the same time
Been using this for many months and have zero complaints! So convenient to be able to dry our filament while we are printing. Wish it was a little more see through so that we could see the filament levels without lifting the top up. So easy to put on your AMS, just remove the stock top and put this one on. We have our printer in our living room and when it’s running it’s very quiet. I wouldn’t say you cannot hear it at all, but it’s barely noticeable! ... show more

  • Own an ams1? this works.
Works just like it should. My Bambu AMS has been sitting at a "D" moisture level all week, I ran the system over night and the next day "A". it was very easy to install. It is relatively quiet and seams to heat evenly. It fits perfectly in the seal of the original lid.

  • Awesome upgrade!
Using on my Bambu lab P1S. It's been a great heater, don't have any complaints. I love that it has its own power supply so you can use it while you're printing. Really makes a difference if you're buying cheaper filament no matter the type. It's absolutely necessary with ABS and highly recommended with PETG. It was a pretty easy install, replaced the factory AMS cover perfectly. ... show more

  • Does the job
This hooks right on top of the bambu ams It is easy to use and works well It does make some noise but not a lot The one thing that would make this better would be if you could control it through the bambu program
