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

The Comgrow PLA 3D Printer Filament is a reliable and affordable option for hobbyists, makers, and professionals who need high-quality prints with consistent performance. With a 1.75mm diameter and a dimensional accuracy of +/- 0.02mm, this filament ensures smooth extrusion and precise layer adhesion, minimizing common printing issues like clogging and stringing. The 1KG spool provides ample material for various projects, from detailed prototypes to functional parts and artistic models. One of the standout features of this filament is its strong layer bonding and minimal warping, making it ideal for both beginners and experienced users. PLA (Polylactic Acid) is known for being environmentally friendly, easy to print with, and suitable for a wide range of applications, including home décor, educational models, cosplay props, and engineering prototypes. The Comgrow PLA Black filament offers a deep, rich black color with a smooth finish, making prints look professional without requiring excessive post-processing. It works well with most FDM 3D printers, and its low printing temperature (190-220°C) makes it compatible with standard heated beds at around 50-60°C. Overall, the Comgrow PLA filament provides great value for money, delivering consistent quality, good adhesion, and reliable extrusion. It’s perfect for those looking to produce high-resolution prints with minimal hassle. Whether you're a beginner exploring 3D printing or an experienced maker working on intricate designs, this filament is a solid choice for your printing needs.

We print a lot on our Bambulabs a1 mini, but live in tropical Hawaii, where humidity can be an issue. This filament dryer is a major help. I use it regularly for PLA or PETG filament before printing to avoid ending up with spaghetti. It is also good for resetting desiccant bags. It only has 2 buttons, so it takes some experimentation to figure out how to get the dryer cooking and set the correct timer, but once you figure it out, it works well. You can tell it is working as condensation collects inside the lid during cook time, even with the tiny plugs open. I just open it up, swab out the condensation, and let it get back to cooking a few times when I see a very fogger up lid.

It works good, just gets very hot after a long period of usage. The rubber piece that closes the hole comes off easily, I lost 2 already. Contacted customer service, still waiting to hear back. The filament quality is great with this on it also enhances print speed and color which helps when I'm printing large pieces. I just wish it didn't get so hot.

This filament dryer is pretty great for the price. It's actually saved a few of my spools from failing to print or just stringing due to moisture, so I can definitely say it works. The interface takes a little time to figure out, but it's not too complicated, and the instructions are very clear. It doesn't feel like any kind of high quality product, though. You definitely get that "cheap, light plastic" feel when you're using it, but for the price it's hard to complain, especially since you don't exactly need to add extra thickness/weight where it's not needed anyways. I do wish this had a specific spot to put dessicant packets though, as that could help with filament drying, and they're not clear about if you could put dessicant packets in the base of the unit or not. I've only used this for PLA filaments so far, but considering it worked for those, I have no doubts it would work for other filament types such as TPU as well.

Works good, especially for price vs name brands. Wish it would go over 6 hours and over 50° but other than that it does a great job. I will buy another one soon so I don’t have to switch around filaments as much.

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.

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.

Works great just like it should. There is no exhaust vent to let the humidity out. But in all it’s great.
