Comgrow PLA 3D Printer Filament, 3D Printer PLA Filament 1.75mm, Dimensional Accuracy +/- 0.02 mm, 1KG Spool PLA Black

I’m genuinely impressed with the Comgrow Filament Dryer Box. This thing has completely transformed the consistency of my prints. The large internal storage is perfect — it easily fits two 1kg spools, and I love that it works with both 1.75mm and 2.85mm filaments, including PLA and ABS. The transparent design makes it easy to monitor everything at a glance. The temperature and timer settings are straightforward and reliable. Once you set your drying temp and duration, the box maintains a steady environment that keeps filament perfectly dry throughout long prints. Before using this, I struggled with moisture‑related issues like stringing and poor adhesion. Now my prints come out cleaner, smoother, and far more consistent. The spool holder and feed‑through design make it super convenient to print directly from the dryer, and the build quality feels solid and dependable. It’s clear Comgrow put real thought into usability and performance. If you’re serious about 3D printing, this dryer box is absolutely worth it. It’s one of those upgrades you don’t realize you need until you try it — and then you’ll wonder how you ever printed without it. Highly recommended!

Great product—it works exactly as described. The price was also fair and very reasonable.

It's a little weird to use but it definitely works for PETG. I forgot to dry my petg the first time I used it and it was super stringy but after drying it in this dryer the print quality was much better. I also like how it can hold 2 spools and dry them. Using it while printing looks like it puts some strain on the filament and the angle is weird, but it still works for all the prints I've done. Only reason I took off a star is because it's confusing to use/change the settings. I pretty much just keep it on the same settings because it's easy enough to start but I have to whip out the booklet and study it to make sure I don't mess it up. I wouldn't let this deter you from buying it though because I think the value for the money is great.

Edit: Seller contacted me and confirmed that the fan needed replacement and will be sending a new fan to swap with the bad one. Changing to 5 stars for fast service and a good unit that just has a bad fan. If you get this I would also pick up a cheap pack of 4010 12 volt fans so you can easily replace the fan, or just wait for the service response. The fan is just below the supports with 4 screws in deep pockets and the connector is held in with hot glue. This unit is good to dry out two 1kg rolls of filament at the same time and you can even feed the filament directly out of the unit into your extruder. The touch controls are a bit unintuitive but are quick to navigate as it is a very simple device, but effective. It is great for hydroscopic filament like PETG and is great to throw new rolls in just to make sure they are properly dry before first use! Bought this unit in April of 2023 and it is now Jan of 2024 and the fan now only makes an angry buzzing/growl noise with intermittent screeches. This unit was good while it lasted, but the fan is an extremely cheap choice for a heated chamber. I'm tempted to see if I can access the fan and do a fan swap and see if that fixes the issue.

Can hold two spools of filament. Temp goes to 40°C to 50°C. You can have it dry from 6 hours to 48 hours. It has temp and humidity on the front display. They recommended having the plugs open for drying but it doesn't exhaust properly. You can keep the latch down and it will keep the lid slightly open and it will get rid of the humidity faster. It has rollers for the filament so you can use it directly with any printer. Overall, it does what a dry is supposed to do. What more can you as from something doing it's designated purpose.

So first off, I'm new to 3D Printing but not to technology and understanding how to fine tune things to get them to work. I am basing my review of this filament as compared to the small filament sample that is included with the Ender 3 V2 on purchase. I bought this filament, alongside the Ender 3 V2 and the CR Touch from Comgrow as part of a sale/discount. I knew I was going to need more filament than what the printer comes with, so figured I'd give Comgrow's filament a shot since I already had the order for everything else ready to go. This filament is very picky about bed adhesion. Even with a bed leveled to ~0.18 variance and the Z-Axis offset appropriately set, it can be very difficult to get this filament to stick to the bed. Once the first layer is down though, the quality of prints have been amazing. For my Ender 3 V2, I found the following settings and experiences to work the best. There's still a lot of baby sitting in the initial layer, so be aware. 210C nozzle, 65C bed. For first layer: 50% Print Speed (or lower if lots of curves), 0% fan speed. After first layer: 100% Print Speed, 100% fan speed. Always print with a brim. 5mm minimum. While the printer is printing the brim, monitor it for adhesion. It'll also give your actual print better adhesion since the initial layer will be bonding to both the bed, and the brim. On any nozzle temps over 195C, I find that this filament likes to extrude during the initial print setup, and will commonly curl back onto the nozzle and gunk it up. Anything less than 200C, and it won't adhere to the bed on the first layer. Due to this, pay attention during the first couple of line prints to make sure the nozzle doesn't have excess filament wrapped around it and that it has shed it correctly. You may need to use the needle like tool to "guide" the filament off of the nozzle before your main print starts. The filament sticks to itself amazingly, so once the initial layer is done you can ramp everything back up to 100%. I've included four photos, one of the initial layer brim of a current print going down problematically (had to lower my z-offset on the fly by 0.1 to resolve), and three photos of a print I finished yesterday. As a beginner, I like the way this stuff prints/looks after the fact but I really dislike how much babysitting I have to do with the initial layer. The filament that came with the printer was not so picky, and I'm looking forward to finding similar filaments as that. The reduced print speed in the initial layer paired with the babysitting increases the amount of time I have to actively spend to ensure that the print is going to succeed. I wouldn't buy this filament again unless I was being very picky about the aesthetics of my print, because this stuff does look great. I would not recommend it to a beginner.

This is a must for drying your filament.

The Comgrow PLA White Filament is my go-to choice for 3D printing. It's reliable and prints smoothly, whether I'm working on functional parts or creative projects. I've found that using filament from the same company that made my printer ensures the best results. The filament diameter is consistent, which helps prevent jams, and it sticks well to the print bed without warping. The spool is well-packaged, too, so I've never had issues with tangling. Overall, it's a solid option if you're looking for high-quality PLA filament that won't break the bank

Muito pequeno (no bom sentido) aquece rápido e mantém o filamento seco mesmo durante a impressão. Só não é hermético e não serve para armazenar o filamento por muito tempo. Aparentemente (e é como vou usar) vai servir para secar os filamentos antes de guardá-los em uma caixa hermética com dessecante e vou usar para impressões longas, para manter o filamento seco durante horas e horas. Super silencioso, estou tentando comprar outro para meu AMS Lite, mas não encontro mais o mesmo preço!

Pudo haber sido mejor lo que me encantó fue que venía totalmente protegida demasiada espuma, cumple con su función ha trabajado fácil más de 5 días seguidos y ninguna queja, el ventilador de serie según yo era muy débil así que le cambie por uno un poco mejor, solo tener cuidado a la hora de donde colocar en tu impresora para no tener atascos y que pueda sacar el filamento de la mejor manera de ahí en fuera todo bien excelente producto

Da un acabado liso satinado, no hay problemas de warping o de obstrucción del HotEnd, me gustó mucho más que los filamentos de acabado mármol

Un produit utile pour préparer ses bobines de filaments avant une impression 3D. Il est très pratique à utiliser avec deux boutons : un pour allumer l'appareil, l'autre pour les réglages de température et de temps. la température est réglable de 40 à 50 degrés. Le temps de chauffe est réglable de 6 à 12 heures. Un afficheur indique la température et le taux d'humidité à l'intérieur du boitier.
