SUNLU 3D Printer Filament Dryer, Upgraded S2 Filament Dry Box with 360°Heating Fan, Filament Dehydrator and 4.6"Touch Sreen, Perfect for 1.75 2.85 3.00mm PLA PETG ABS Filament(White)

Best filament dryer I have used.The standard function of the dryer is great. Heats up to cover multiple filament types. Has a fan to keep the airflow moving for even drying.Where it excels is the LCD touchscreen.Easy to set parameters.Easy to adjust parameters during drying sessionEasy to check current humidity level while you are drying.Being able to know if the filament has removed enough moisture is one of the most important things you would need to know. This is the only dryer I know of that offers the sensor to report current humidity level.Works great!Easy to setup and use!

I bought this but as others mentioned it doesnt vent the humidity well. You can open and close it real quick and see it drop. Best way to fix this was print a piece that helps lid stay cracked. Plenty of them on makerworld. I usually dry with lid cracked and for the last couple hours I'll seal it up entirely. Seems to work well.

I was experiencing poor quality prints and was out of ideas. I gave this dryer a shot and sure enough it was moisture on the filament causing issues. This is an attractive design, heats from all sides, and is basically silent when running. I like that it isn’t bulky so fits inside my enclosure nicely. Highly recommend.

Had to figure out how to turn it on, but after that it worked great. (Double click the on/off button.) Very impressed with the touch screen. Heated up quickly and holds temperature steady. Relative humidity went from 55% to 20% in just a couple hours. This was while drying ninja flex. Can set the timer for much longer than other units. The temperature goes all the way up to 70C to dry nylons which is a huge upgrade. By far the best filament drying unit on the market for this price. The only thing I would change is making the hole further down on the container. I place it on top of my lack table for my Prusa. If I use the filament hole there is a lot of friction when pulling it out and down. This is really only an issue when printing ninjaflex because the filament stretches, reducing its volumetric flow. Right now I just have the lid slightly propped up and run the filament through there. Similar to the last model.Some of these other reviews thinking the filament will loose significant weight during drying is a little far fetched. Maybe nylon. Then feeling humidity come out when opening the lid made me laugh. If you want more venting prop the lid up slightly, but it may be tough holding it at 160 degrees F.I never write reviews but am very happy with this product. Will buy another one soon.

This nice little unit does exactly what it says on the label. Heats up quickly and keeps the PLA filament dry. I definitely saw an improvement in my print results. The controls are easy to use/navigate, and it will be an integral part of my printing routine going forward.

As often I did a bit o research and eventually settle for the SUNLU. THe unit seems to be well made and the large lcd is easy to operate. I did not test humidity levels with other instruments but the readings seem to correlate with the temps. The other reason that leads me to believe that works is the same that took a star away. Without using the 3D part that someone cleverly designed and made available on thingiverse which is essentially a spacer that leaves a gap open, the humidity stalls well before the optimal range of around 20%. Given the simplicity and effectiveness of the mod, the solution should be implemented by the manufacturer.Al in all, if you set your expectations right, this is a great little unit that does what it should for a good price.Happy printing.

The media could not be loaded. The product looks sleek. A much better design than the S1. Easy to use as everyone has said. I was a little concerned at first because the RH (relative humidity) went up instead of going down. I'm from Texas and it can get pretty humid in and around the house. I had a lot of my filament just sitting out in the open and no dry box or containers.After thinking about it and speaking to their amazing customer service, it makes sense that the moisture that's being released during the heating/drying process would cause that number to go up.Took a few dry cycles to get my stuff to some more reasonable numbers but boy has that adhesion and print quality improved! Looking forward using it on other spare spools to see how it performs.

Let's start with the positives, the unit powered on and the screen is clear and is easy to enter inputs. Now the cons. The relative humidity is wrong. I can put a roll of filament in the unit (starts out with a RH of 42%) and run it for 8 hours. If you are lucky the RH drops maybe drops to the upper 30s. The RH setting and reading are wrong every time I have tried to use this unit. Ther filament holes are at the wrong angles and causes drag on the filament. The instructions are a joke to include the "detailed" manual you can download from their site. NOT recommended.

A lot covered by others, but a couple of key points:1 - there is a fan in the S2, and it isn't too loud in my office; however, I wouldn't want it in a sleeping area.2 - The unit does dry the air and circulate it. Unfortunately it is an entirely closed loop (not hermetically sealed, but not a lot of leakage), so the moisture released just travels around the anulus around the filament spool. I found that if I lifted the lid for about 5 seconds and then closed it up again the humidity generally dropped by 1-2% per the incorporated meter. I don't know if this is real, but it seems likely. A future design upgrade might be some sort of limited draft vent to bleed off some of the moist warm air - it is really all about driving the water out of the filament by heating it, so letting in a small volume of damper room air is inconsequential in the whole scheme.

Tiene temperaturas predefinidas, calienta toda la circunferencia del rollo. El rollo rueda libremente y es buena opción a buen precio

Es sieht gut aus und funktioniert perfekt. Es ist leicht einzustellen und die Filamente werden wieder trocken.

Como digo, es una muy buena caja de secado, económica y funciona correctamente. Deja configurar tiempo y temperatura, aunque si le pones el tipo de filamente te ayuda a establecerlo por defecto. Realmente quita la humedad y el filamento se imprime mejor. Sunlu muy bien.

Très simple d'utilisation, fonctionne bien. On voit tout de suite la différence de qualité sur les impressions !
