My black PLA was unusable, brittle and splodgy in the print. 6 hours in this and it was back to normal.
I think it is a necessary item if you live in cold, damp England !
Was a bit dubious about ordering as I’ve heard mixed reviews. Put a spool in and warmed it to 50 degrees. The humidity was nearly 70% and this took it down to about 37/38 and done a print straight from the heater and immediately noticed a difference with print quality, and very very minimal stringing! A worthy purchase. As humidity in the UK is high at the best of times this time of year. Definitely made a difference!!
Should have bought one of these years ago! What a revelation, I store my filament in airtight containers with lots of desiccant, however I’d been having problems recently with stringing, poor adhesion and general quality issues, suspected damp filament so dried a spool behind my log burner which improved things but not really that practical so purchased this dryer, it’s silent in operation, only uses about 50 watts of power and has a nice easy to use display. I put a pack of desiccant in the middle of the spool when drying to help soak up any moisture. Lastly I’d never managed great print quality with PETG but after putting it in the dryer it prints perfectly. Really pleased and would recommend to anyone who has a 3D printer.
My printer is in my outside office. Its heated but probably not ideal for 3D Printer.. Adding this unit has made a huge improvement to my prints. No stringing and a far better finish. The Sunlu heater just sits alongside the Printer and feeds the spool, easy. I saw the humidity figure drop from mid 60s to high 30s. I power up the Sunlu heater 30m before using the printer to dry out and warm the spool, then its good to go. It’s made a great improvement, like having a new Printer..! Very pleased and happy to recommend.
bought because i was willing to try anything to stop stringing – done all the calibration tests, swapped nozzles got the bed all sorted and still… (ender V2)
5 hours ‘cooking’ the filament in this and the improvement is.. big.
Better adhesion. less stringing and it’s helped a ‘stock’ filament perform as well as a pricier branded one.
I cook the filament ever couple of days. Probably overkill. But seems to work
Would recommend for sure
Works as described, nice dry filament seems ok so far.
You can’t go wrong with it, I had a bunch of S1 for my Voron and always had to mod those.
S2 doesn’t require any mods, has built-in thermal insulation (uses less power), works with timers up to 96h (or something similar), has a built-in humidity sensor, and works with higher temps.
Thanks to S2 I was able to re-use PLA & PET-G rolls that were out in an open for over 2 years !!! It took like 5 or 6 days to achieve 15% humidity (this meant that the filament is dry enough).
With S1 I never knew if it is ready or not without modding.
LOVE IT!
Well, what a difference this has made! You’d be surprised how quickly your pla goes funny. I’ve been using this for the last couple of weeks and you can see the difference straight away. My prints are now a lot cleaner and are less stringy that is caused by the moisture in the pla.
The product it’s self is great. Lovely big touch screen with bright, clear writing that shows all the stats for temp, humidity etc. The spool within then the dryer is on rollers and moves freely with no issues. So far no issues. Highly recommend! I’ve included a couple of images too.
Bought this as I already have a sunlu dryer but wanted to see if this was any better ,given its all round heat top and bottom. And although this is only 20 more than there other dryer it’s well worth the extra. Your wonder why you haven’t bought one sooner , there that good . I couldn’t be without mine now .
Did what it was supposed to do, dry filament , easy to setup and use.
This product did not disappoint me.It working above my expectations
This a brilliant bit of tech, if like me your new to the world of 3D printing then getting one of these is going to save you hours of hassle with stringing prints, bed adhesion issues and more.
Great unit SUNLU nailed i
This a very well put together unit I have wanted a filament dryer for a while and don’t like the lack of information you have on them until this one the display tells you everything you need to know from Temp, time and humidity. It comes with several presets for things like PLA, PETG, TPU, PC and PA. You can customise them so if you want more time or more heat then you can. It’s limited to a max of 99 hours (just over 4 days) and the temp goes from 35c-70c
Would I buy again yes I may get one for each of my printers.
Really happy with Sunlu’s S2 filament dryer, as a newbie to 3D printing I didn’t realise how much difference there would be in the print quality when using properly dried filament. Nice big touch display which makes it easy to operate, overall very happy with the purchase. The only critique I have is I wish they had rubber fittings on the legs as this would stop it sliding on a smooth surface.
Receiwed mine one quick.very nice looking drybox,easy to use,nice and big touch screen.
2 heating elements,heat quickly.does have moisture indicator,and nice led ilumination.Ready tried on my old petg,works great.very happy with purchase.Great job Sunlu.Recomended
