Official Creality Space Pi Filament Dryer Plus, 2 Spool 3D Printer Filament Storage Box, 360° Fast Heating Dry Box with LCD Screen, One-Key Drying for PLA PETG ABS TPU PC PP ASA PET PETG-CF

Works as intended, dries filament quickly and it's quiet. Haven't had any print quality issues since using this product.

It does it's job, and it does it well. Overall, I am happy with my purchase. I have a roll of clear TPU I had sitting in a non-air-tight bag for about 6 years in the basement and decided to see how bad moisture impacted it. (It was really bad, as can be seen in one of my pictures.) Threw it in the drier with the recommended settings and got impressive results; it dried out the filament and made it printable again. I also recently purchased a spool of Elegoo rapid PETG to try out the brand and was disappointed with its performance out of the box as it was laden with moisture. I would have been annoyed and writing an email to support because I had an unusable spool of filament, but this drier came in to save the day. Now I'm just annoyed, but at least I have a usable spool of filament. Having saved two spools and used this to guarantee an additional two spools in my collection were good to work with before large prints, I can say my investment has already paid off. (Included in my review are also thermal images of the drier running; it's pretty interesting to see the channel the hot air is blown through by the fans and how it heats the spools.) I am however disappointed with the quality of the touchscreen; it feels very cheap, has visual artifacts when pressing on it, and mine arrived cracked. (You can see some hairline cracks light up in the display itself when pressing on the screen to use the interface and they go away after a few seconds.) The screen is still fully functional, just looks bad when you need to touch it.

Once you get used to the awful interface, it is pretty easy and quick to use. As with most filament dryers, this suffers from a design "flaw". This dryer (like most) just ends up heading up the air inside. And it does this very efficiently and rather quickly. However, what it doesn't do, is allow any moisture to escape. For example, after running this for well over 8 hours, I noticed the humidity wasn't going below 29% (with the ambient humidity at 41%). I cracked the lid open with a pencil and quickly watch the humidity level drop and settle at about 15%. It does seal up nicely, not super air-tight, but enough that with 3D printed desiccant holder (in the spool), it maintains a rather low humidity even if I go a week without actively drying. My only complaint is pretty minor. It's pretty noisy. It seems to be louder than the printer with the case fan running at full blast. I have both inside a cabinet so it's not too bothersome.

I liked my first so much that I got a second. I used my own thermometer and hygrometer to check if the outer readings were true and accurate. They perform very well. I don't really need drying where I am, but we've had a few weeks off heavy rain and these kept my filament dry. It's also great for keeping dirt and dust off your spools. They do make a high-pitched whine when drying, but it's not that bad.

This is a nice dryer that has worked well for me for dozens of spools. I have no reason to think this won't last for a long time. It effectively removes humidity and has improved my print quality for several spools that "should" have already been dry. I do think these are all somewhat overpriced, but this one is on the lower end of the price spectrum, and it works well and is easy to use.

Using it with Sainsmart and Bambu spools, everything rolls great and it dehumidifies all my TPU effectively

Love creality items tbh. This one works great for keeping my CF filament

I was expecting better quality from Creality. It feels very cheap and somewhat fragile. The lid especially so with how wobbly the hinge is. Speaking of the lid, this is supposed to double as a dry box? There's no seal or clamp, when you close it it's just a thin plastic laying against another thin plastic edge and even that is questionable because, again, how wobbly the hinge is. Listen to the other reviews about the display; it's got some issues. I thought maybe they were just isolated cases. Nope. The dial should work fine in theory but in actual use it's a little annoying. How it SHOULD work is the first press activates the selection option, then you turn (or not) to select either temp or time and then press again to select it, then turn the knob to adjust that, then press again to confirm. It doesn't work like this. Pressing does nothing to begin with, you have to spin the knob before the device recognizes you're trying to adjust something. Sometimes it's quick, sometimes you're spinning repeatedly before it "wakes up" and the option starts blinking. Then you press, then turn to adjust, and press again to confirm. Now you get to spin, spin, spin until the other setting gets selected and then you repeat the process. If you're selecting temp pressing the first time shows a 5h timer. If you turn the knob to adjust it it resets to 0h and goes from there. It's a little confusing until you get used to this odd behavior. Generally, it feels like there's an extremely underpowered processor running the thing that has trouble even keeping up with the screen. Which is likely the case. So does it keep temperature? Yes. I mainly use it for PLA and run it at 50c and it will get there and stay pretty solid. The humidity gauge is something else you should listen to the other reviews about. It bottoms out at 15%, which is kind of sad considering no-name Chinese hygrometers sold in a 2-pack for next to nothing on Amazon will go down to 10%. It also isn't apparently kept updated unless the heater is actively running. I've seen it display 15% for hours while I had it idle after drying some filament and when I put another roll in and turn the heat on it instantly shoots up to 25-35%+. I've seen this behavior even when I turn it on without opening it so it's not a sudden inrush of moisture. And speaking of that, one common problem dryers like this have is the lack of venting for said moisture. Sure you could probably keep the filament hole in the back unplugged but I don't think that's sufficiently large enough to vent effectively. So prop the lid open just a little bit. I find a filament clip clipped onto the edge of the lid to work very well. It may seem counterproductive but it isn't. When dryers remove moisture from the filament it needs somewhere to go. If it's stuck inside circulating it'll just condense on the lid or worse, the spool/filament. As long as you don't have the lid wide open it'll still stay hot inside. If you want to test this start drying a spool and if you notice the humidity level staying relatively the same for a long time crack the lid and watch it suddenly plummet. So, yeah, it works. That's about the only positive thing I can say about it. I wish I'd gotten a different dryer.

La verdad tenia mis dudas sobre si realmente valia la pena tener un secador pero la verdad esque si y en especial este producto me subio mucho las expectativas porque como yo soy de clima humedo peleo mucho con la humedad en los filamentos y la este secadro hace su trabajo dd maravillas por bastantes horas sin perder precision puede mantener la camara a la temperatura deseada por mas de 8 horas sin variar por desgaste de uso continuo y junto mi ender 3 ve KE va de maravilla ya que tiene una salida para cada filamento para alimentar la impresora directamente sin sacarlo y seguirlo secando mientras si imprime lo cual mejore mucho la calidad de impresion esto ayuda muchisimo para el TPU y el PETG que son los mas hidrofobicos la verdad me quito todas mis dudas!

Les deja un pequeño porcentaje de humedad pero cumple con su función

Works amazing! So much better than using the heated print bed. I also like that it has the rear port to be able to directly feed from the dryer into the printer.

Tengo unos 5 años de experiencia en la impresión 3D y noté que en los últimos meses medio mundo recomienda secar tus filamentos para mejorar drásticamente la calidad de las impresiones, así que decidí probar con este producto de Creality, cabe destacar que siempre he mantenido mis rollos en bolsas ziploc y con sus respectivas bolsas de desecante, esto no cambiará. El secador funciona bien, no tuve problemas de mal funcionamiento como otros comentan pero lo único que no me gustó es tener que usar tubos bowden para meter el filamento en ellos y después en tu impresora, uso impresoras de extrusión directa y esto claramente afectará a las configuraciones de retracciones, también noté que el extrusor necesita hacer más fuerza para jalar el filamento, hay más resistencia a causa de los tubos y esto no me gustó, no quise forzar el motor del extrusor y al final solo seco los filamentos, los saco del secador y los coloco en el portarrollos de mis impresoras como siempre lo hice. Se nota la diferencia en la impresión, también se nota en los rollos, estos hacen un ruido peculiar al manipularlos, como rechinidos, el material al estar seco rechina cuando tiene fricción entre si, creo que esa es la señal de que ya están listos para usarse. Otra cosa que noté, cuando abres la tapa del secador, al instante baja algunos grados el porcentaje de humedad en la pantalla, como si estuviera acumulada en el interior y al abrirla "liberas" algo de esa humedad. Puse sin preocuparme un rollo de PLA y otro de PETG con temperatura de este último, veo que al usar 60 grados la humedad baja más rápido, pero pienso que es un error del sensor, parece ser que a 60 grados si indica la humedad correcta y 50 tiene menos precisión. Si tienes un PLA un buen rato con sus 50 grados y notas que no cambia el porcentaje, prueba subirle a 60 (cambiar a PETG) por unos minutos y verás como baja más rápido, no sé que daño se pueda causar al filamento si es que lo causa, pero yo dejé un PLA por horas junto con un PETG, después imprimí sin ningún problema con ambos.

Funciona bien, he podido rescatar filamento que venía con humedad, se nota el cambio en la calida de impresión despues de procesarlo en la caja. Es recomendable ver la tabla de temperaturas y tiempo para cada material que viene impresa en la hoja. Los únicos contra que he visto hasta ahora es que el manual no viene en español, el orificio por donde sale el filamento no parece muy resistente y que el indicador de humedad en tiempo real no parece que realmente funcione.
