SUNLU Official Filament Dryer S1 Plus, Built-in Circulation Fan, Filament Dryer Box Storage Box for 3D Printer Filament 1.75 2.85 3.00, S1 Plus White

Generally I don't have an issue with any of the PLA that I use. Purchased this to try some TPU. Can't use TPU on my AMS lite so now I will be able to dry and feed from this dryer without a large investment.

I like this dryer it allows for up to 99 hours of drying withjout resetting the control. it has a out the front or out the top front feed to allow for pisotioning it on or around your 3d printer. i have had a couple and now only use SunLu

Moisture content seems to be low on a PET-G filament I cooked in here. Although, it also warped the PLA spool, which I thought was kind of interesting. Looks good, small, and probably not a bad idea for a starter. If I could do it again though, I would buy a multiple chamber/roll filament dryer.

My filament fits and rolls around inside without much friction. The controls are annoying - only two buttons to navigate all the menus and change settings. Normally this doesn't bother me because I just press one of the buttons and the dryer turns on, heats the filament for 6 hours, and turns off, which is what I want it to do 90% of the time (the other 10% I want it to stay on longer, which I can do if I fiddle with the controls for a bit). Would be nice if there was a way to disable the backlight because it's annoyingly bright at night, or maybe there is a way and I need to read the manual again. I like that the buttons are actual buttons and not capacitive regions or membrane switches.

If you don't already have a filament dryer, get one. And while you're at it make sure you get this one. I use this filament dryer for every print job. I start it up hours before the print just to make sure the filament is dry and I print straight from the filament dryer. This seems to do a pretty good job at removing moisture. Prints never looked so good.

I am very new to the 3d printing world. I was told by a lot of people to make sure my filament was dry. I didn't want to get the most expensive dryer so I found this one that is a really good price. Aside from the price this dryer is very high quality and it works perfectly for keeping my filament nice and dry.

love the drier works great

Update: I've been forgetting to update this for a while now. After using it only about a dozen times for 8-12 hours each, the fan bearings gave out and made it very noisy. So it lasted less than 6 days of actual use. File a warranty claim you say? I did and only received crickets. Very disappointed. It's even designed in such a way to make it very difficult to work on it without tearing it apart. Poor quality product from a useless company.This Sunlu Filament Drier is really low quality and feels cheap. There are 2 buttons on the front with no markings nor indication of what they do. They could have at the absolute very least put a "T" for temp and an "H" for hours on the buttons. Comes with tiny PTFE tubes without any mention as to what they are for, not even on their YouTube video. There is a plastic plug that is supposed to go in the unused hole, but it is poorly sized and poorly implemented so it constantly falls out.How about turning it off? Well, you have to turn you time down to 0 hrs, 1 hr at a time, then hold the left button to get it to shut down. Most times it is just easier to unplug the darn thing.The instruction are very vague but enough to get you going with regards to what the buttons do, but this doesn't give them a pass for not being marked on the unit itself. The vague instructions tell you to scan a QR code to download the full instructions. Why? You already took the liberty to put a glossy, full color pamphlet in the package. Just give me the last few pieces of information! Like what the extra PTFE tubes are for!The unit falls back if you open the lid without any filament in it. As it heats up, any moisture turns the unit into a sauna because there is no directional air flow into and out of the unit. Meaning for it to work correctly, you would need to open the lid to get some fresh air in there.What I do like is that it says it can go to 55° C which is higher than most at the time of purchase. That said, who knows if it actually goes that high. It looks nice for the most part. I like that they implemented 2 holes for filament to go through as it is nice to have options. I will likely keep both holes open since the plug doesn't stay in place very well in the first place and secondly, the 2nd hole can serve as an outlet for moist air to exit. Time will tell how long it lasts.Ultimately, I regret buying this one and expected better as these have been out for a long time now. :( I only give it 2 stars because it does work.
