I've used this E2 filament dryer for the last 4-5 months. It's one of the few dryers that can get this hot, and it's a game changer IMO. If you're just using PLA or PETG this might be a little overkill, but it's almost a necessity when drying engineering filaments like carbon fiber nylon. Prior to this people were (and still are) converting food dehydrators into filament dryers, and that just seemed like such a hack-job way of doing things. This machine is easy to use and gets extremely hot and it can be set on for LONG prints without turning off. Cons: it's a little pricey, it's fairly large, and fairly heavy. As another reviewer complained it is fairly loud, but I don't see how you're going to get around that. You've got a printer running, and if you're printing engineering materials inside you've likely also got a HEPA filter and evacuation fan running, so yeah, it's another device with a fan. Overall, it's worth the money if you're serious about drying out stuff like ASA, ABS, PA6-CF etc, and will dry at the proper temperature in half the time of the cheaper dryers.

The media could not be loaded. Performance:***** Aesthetics:***** Ease of Use:**** Value:**** Overall:4.5 If you are reading this review you are probably wondering if Sunlu corrected the flaws that were uncovered during the initial previews of the E2 with the prerelease units that were provided to youtube 3dPrint-Fluencers such as Aurora, Dr.I gor (MyTechFun), and Modbot. So to address the primary concerns, the lid remains closed and does not deform during use even when set to 110C. Yes it dries filament, and it can anneal nearly everything that you would print in an advanced ProSumer 3D-Printer with a chamber heater. It may overshoot the temperature by about 4 to 5 degrees C, however my measurements this could be incorrect as I used a bbq temperature probe instead of a laboratory grade thermometer. Yes, it really can reach 110C , so it will melt most spools. It can easily cause the glue to fail in cardboard spools ( Polymaker and Siraya Tech) Make sure not to exceed the max temperature of the spool of your filament. Currently this is the only dedicated Filament dryer that can effectively dry Nylon in a reasonable amount of time. You can dry nylon in four to eight hours, versus taking three days to dry in a PolyMaker Polydryer or 12 hours in a high temperature food dehydrator. However the price will give most interested users pause. At its full retail price it's smack in between high-temperature dedicated filament dryers such as the Creality Space Pi 4x and a dedicated Lab oven. Which ultimately means that it's priced correctly and we are fortunate that Sunlu was able hit this price point. I don't think this unit will sell as much as their previous offerings like the S4 so development and tooling costs are spread over a significantly smaller number of units. My only real complaint is with the noise of blower fan that they placed to cool the electronics on the bottom. They should have placed a larger blower fan that could hit their airflow/pressure requirements as there is sufficient space to install as 7530 blower, doing so will only require to enlarge the air inlet hole on the bottom of the E2. I have included a brief video to demonstrate. Ultimately, if you need an attractive dedicated filament dryer to dry nylon in hours and not days this is the only game in town and is worth considering. Bonus: You can anneal PLA,ABS,ASA,Nylon, PPA and PET-CF/GF. Annealing PPS-CF/GF and PC are really outside the scope of this dryer. Some PC-Blends might be annealable at 110C but most will not. You can trust the manufacturer's Data but Verify!!!

The Sunlu E2 should really be labelled the Sunlu E2 Anneal Oven and Filament Dryer. Yes, it is the priciest dryer. The value in this dryer over its competitors is it's 110C max temp for annealing, and drying of engineering filaments. In this aspect, its in a league of its own. If you aren't going to be annealing or using engineering filaments, I would go with the Sunlu SP2, or if you're a Bambu person, the AMS Pro 2 or AMS HT. The auto-dry M3 mode where it turns on the dryer if the internal humidity hits 30% is nice. The Sunlu E2 is well made and it's OSD is relatively easy to use and straight forward. The plastic is very sturdy and very thick. There are some things I would prefer be improved: 1. I do wish it could do auto spool rotation, or the ability to keep the chamber more air tight, both of which the Bambu AMS Pro 2 and AMS HT can do. 2. It would be nice if there was an auto valve for allowing for the release of humid air.

This is my favorite dryer. I purchased this dryer for drying engineering filaments and to dry/hold larger spools (3kg spools won't fit in my other dryers). I have used it to anneal PC and ABS prints and it does a good job at this. I also use it refresh my silica packets. You can fit a bunch of silica packets on the annealing tray and dry them out pretty quickly. For drying 3kg spools of engineering filaments, there aren't many options. This one fits that use case and does a great job at it.

Reviewed in the United States on February 25, 2026 by These ties are the size that might fit children. Way too short. Not for men.
The media could not be loaded. Do not recommend, product arrived faulty, I am unable to adjust the temperature down leading to the temperature being stuck too hot. Have been in contact with customer support since November and still have not reached a conclusion.

This is wonderful! Love the temp capabilities. Fan is as loud as expected, and actually quieter than my Polydrier but has more capacity and temp. Can’t really hear it while my enclosed Bambu H2C printer is running anyway! Love it!
