Short(ish) version: I'm a medium-level 3D printing enthusiast, 3 years of mixed experience/results with an Ender 3 since 2020. I picked up the SV01 Pro in October 23 and it was so easy to build and use, but I wanted more build area, plus a second printer so I could run concurrent print jobs. I did a fair bit of research and determined the SV06 PLUS to be a solid value. Purchased this guy November of 23, and holy cow was that it a good decision. I mean, here are some of the important boxes this printer checks for me: 1) More build volume 2) Higher print speed capable 3) Self-leveling (not perfect but shockingly good!) 4) Pause/Resume when it runs out of filament (more details below how this saved my six-day print) and 5) In general terms, for my uses, this was a wonderful next step in my 3D printing hobby. Honestly, I can say my new printers have made printing FUN again, and I get to spend time printing again instead of constantly calibrating in between prints. More details: I'm not here to trash Enders, especially since my Ender got me into the hobby (January 2020). I did however eventually get tired of the bed leveling, failed prints, and constant babysitting. To tell the truth, I was hardly printing any more come 2023. My coworker was talking about this SV01 Pro he got cheap and how reliable it was. I said why not, got myself an SV01 and was just instantly having a GREAT time! My only problem - I had the desire to print larger stuff. I joined the Sovol groups on Reddit and FB, and did a lot of reading. The clear consensus was that the SV06+ is one of the best bang for the buck printers available in general. I chose the standard (read: non Klipper) model. Klipper is a whole other (and interesting) topic but I'm not looking to address that in this context, I may tinker with it on my Raspberry Pi later, but I'm just running things stock. So the SV06 arrives, and within about 30 minutes I had assembled it and started the leveling process. As soon as that was done I connected my Raspberry Pi with OctoPi and set up a printer profile so I could print from my PC instead of using the SD slot. I'll go ahead and mention the con I have with this printer because this is where you'll notice it too: The power supply has a significantly loud fan. It's not a deal breaker for my situation because my printers are in the basement, but trust me about the noise of the power supply in case that would be a problem for you. Anyway, It's been about 4-5 weeks of non stop printing for me. I've shared several photos, and one video for this review. I printed a cool marble track model but should have scaled it up in size because it would only fit smaller ball bearings. Turns out the SV06 was big enough to increase the model to a size where I could use regular marbles! The model took up most of the build volume on the SV06 and would provide a great stress test. This beast was a 6-day print and on day 4 when the spool of filament ran out, the filament sensor on the printer paused it automatically, moving the hot end to the side so I could mount a new spool and load the filament. Then I hit resume (holding my breath because I hadn't actually tried this before) and it just picked up where it left off. If you check my video, you can see the finished product which is pretty cool - it has an Archimedes screw that lifts the marbles back up where they randomly fall out to the 4 different tracks and down again. Summary - I hope this helps someone that's on the fence! Potential buyers should be aware of the loud fan on the power supply, but I can sincerely recommend my SV06 plus based on my experience. It's fast, it has been reliable, it successfully printed a monster print for me (hopefully the first of many), and it's been easy and fun to use. I still don't know if I'd call it a "beginner" printer, but I've been teaching my son and he picked it up right away. We're having a blast printing organizers and accessories for a bunch of our favorite tabletop games. Two thumbs up!

Updated Review: We had the extruder nozzle snap off and become bound in the hot end. The nozzle looked like it was made of very low quality metal so we are likely to look for a more durable replacement. I contacted Solov customer service and they informed me that since it was purchased on Amazon we needed to contact a separate support group. Ok, so that group was initially helpful and it looked like they were going to handle the replacement as expected, but suddenly they just stopped responding to email and provided no updates. I ended up just buying a replacement part directly from Solov. Due to my customer support experience, I can't recommend this at all. Original Review: Updated with Klipper Pad: Still an amazing 3D printer that produces outstanding prints. Here are some additional observations - The out of filament sensor works great and the software allows for seamless continuation. The print times are really fast, with good quality. I really like the heated bed and good first layer adhesion. Original Review: This Solov 3D printer is what 3D printers should have been all along. We were early 3D printer adopters and have 4 other models from various manufacturers going back several years, but none of them worked well out of the box. Setup and calibration took us about an hour or so and the provided instructions were easy to follow. We made a few test prints with the included PLA spool, including the articulated Dragon shown in the picture. The detail and speed with the default settings was quite impressive. Be sure to watch the many available videos on setting up, tuning, and using this 3D printer. Highly Recommended! CFH

The printer arrived on time and in excellent shape. I was surprised at how well it was packaged. I have definitely bought printers that had lots of loose stuff in there to bang around or was already broken when I opened it. It was easy to open and remove the printer from the packaging. This Sovol SV06 plus includes everything you need to get started. Everything is in there and well packaged and marked including tools and extra stuff you might need. Also includes a small roll of white filament, not like other printers that only include small sample of filament, the SV06 comes with enough filament to do a small print, looks like at least 200 grams. So there is a enough of everything to get started. It was amazingly simple to assemble. I like that the screws are all marked with the step number for each bag off screws and not just a bunch of screws in a bag. There is no doubt which screws go where. The instruction are very easy to read with detailed illustrations that have arrows that point to exactly where each component goes and right where each and every screw goes. Some printers come with no directions and just a link to a video. The printer is almost completely pre assembled in 4 main pieces,the base, X/Z gantry , power supply and the print head. There are less than a dozen screws to install to assemble the whole thing. All the screws are clearly marked by the steps so nothing is left to chance. I had it together in less than an hour. The construction on this machine is amazing. I have a small printer farm and am a professional 3d printer and have 17 printers of many different kinds. There was a lot of thought that went into every detail. First it comes with 2 different bed choices, the sticker kind which could work but more importantly it has a nice flexible PEI bed that looks of high quality this is very important to bed adhesion and print removal. Dual z axis motors with linear rod bearings instead of wheels that need constant adjustment this is a feature found only in higher end machines costing considerably more. This feature alone is what drew me to this model because it will be stiff and will require less maintenance and adjustment. It has an inductive bed leveling sensor, again found in only the upper tier of printers. Inductive bed leveling sensors don't use a switch like most bed leveling, it is done wirelessly so no moving parts and very concise readings with high repeatability. A high quality direct drive with dual gear extruder with a volcano style hot end makes this printer not only fast but with enough flow to do the job. The entire package is user friendly with a very readable large touch screen that is easy to understand and use. This is a very beginner friendly machine. The touchscreen menu is understandable and easy to use. Setting the Z offset was a breeze. And with the high quality bed leveling system getting going is a breeze. The printer is quiet also which is nice, quieter than most if my other machines. Also it has a large size bed at 300x 300 making it bigger than most lower end machines. You could definitely print a full size helmet on this because I have done it on similar size machines, this is a feature that can be very important from a business stand point and for future projects. All together a very user friendly experience and I am looking forward to many more hassle free, fast prints. I actually saw this machine at a competitors print farm and was drawn to all the high end features it had. I thought it was one he had done some heavy modifications on, when he told me, "This is how the printer comes stock." I had to have one. I will most likely get a few more while they are at such a good deal.

I wanted to give myself a few weeks with the new SV06 Plus before writing a full review in order to give myself some time to put it together, work out any kinks, and put the printer through the paces. First, a bit about me - I currently have three other 3D printers; an Ender 3 Pro, an Ender 3 v2, and an Elegoo Mars 2 Pro (resin). I am an experienced user, but certainly not an expert. I have upgraded the boards for both of my FDM printers many times, am familiar with flashing firmware (Marlin and Klipper), am comfortable with hardware changes (complete hot-end conversions), and am proficient with small electronics. That being said, the SV06 Plus has been by far the best first-impression printer I have encountered! The assembly was hands down the easiest with preassembled parts, clearly labeled hardware bags, and well produced instructions. All of the bolts seemed to be tightened properly from the factory and I was up and running in no time. I was also pleasantly surprised to see Sovol include a much larger sample roll of filament (on a spool!) than I was used to. Given that the Plus printer has such a large print volume, it is nice to see a company include enough filament to actually get a feel for the larger print area. After some initial configurations like adjusting the z-offset and leveling the gantry I loaded up the SD card to print one of the test files that was included. That's when I ran into my first issue; my extruder was not extruding properly. I had clear signs of under-extrusion (blanks in the print, air gaps, and layer spacing). I calibrated the e-steps but it seemed like the extruder knob was turning without actually extruding filament. I took it apart and cleaned it out and I think the filament that was left over in the nozzle from the factory testing (kudos to Sovol for at least testing the machine before sending it out!) might have been causing a clog. Got it cleared up and printing but the results were less than ideal. There seems to be some sort of resonance issue on the hull of my benchy (see photo). Still haven't gotten than figured out yet, but I think it has to do with either the x/y axes or the table the printer is sitting on. Because it is such a large printer moving at high speeds, it tends to move the table just a little. Another thing I have noticed is that the linear bearings are pretty loud. Looking around the community it seems that Sovol missed a crucial step by not packing the bearings with grease. This meant I have had to take the bearings off and pack all of the bearings myself. Not a huge job, but a pain nonetheless that I shouldn't have to do myself. One of the more nit-picky things to me is that the factory cooling fan is in front of the extruder, obscuring the view of the nozzle. It would be better for it to cool from the back so that I can more easily see the nozzle and observe my first layer print, a crucial step for FDM printers. This is easily remedied by printing a replacement fan housing, which also gives me a chance to upgrade to a larger fan as well. Overall I think this is a phenomenal entry-level printers for someone looking to get into the hobby. I would probably suggest that someone knew go with the standard SV06 rather than the Plus, simply because a larger printer introduces new variables into your prints. It would be better to get proficient at standard printing before you dive into large-scale prints. Eventually, I will be replacing the motherboard and upgrading to Klipper to match my other printers. Can't wait to run a large print on this thing! tl;dr The Good - well-packaged, assembly is a breeze, large filament sample, touchscreen is odd to navigate but better than a rotary dial screen, FAST print speeds The Bad - Extruder issues on first prints, resonance ringing (which may be my table moving rather than a bearing issue), unsure if the runout sensor is working properly because it doesn't seem to stop the print if I force a runout. The Ugly - having to disassemble the printer to pack the bearings is not something that a new user should have to do. Those should have been packed from the manufacturer.

So I should start by saying I am not a full time maker and am not out creating things to sell. I mainly use mine for costume & prop making for film and stage. My first printer a few years back (after so much research before buying) was the SOVOL SV01. It was easy to setup, easy to use, and easy to maintain. After years of use, and wanting a bigger and faster machine, I went with the SV06 + and I can tell you that it was worth it. Machine is super easy to assemble and get printing. If it is your first one, the setup is simple and takes a little practice and patience, but for any experienced printer, this machine will be up and running in less than an hour. Pros: It's bigger and faster than the SV01 (obviously) but smoother to use. Touch screen, auto leveling, easier load and unload, it all just feels more enjoyable. I had a glass bed on my older unit and heard great things. The PEI bed is great and I am a bit ashamed I didn't use it for the last few years. Easy to print on, and easy to get prints off. I ran this thing pretty regularly for the first month of having it, including a large print (a negative mold for a prosthetic) and it went fantastically smooth. Even faster than the estimated time on my slicer! I have tried increasing the print speed as well for less detailed work and the quality is still pretty clean. Cons: It isn't the smoothest sounding machine, especially at the initial start up. Movement on the bed and extruder on the extremes sounds more like a hard stop than a smooth position ending, but I wouldn't say that seems to be an issue. Printing is fairly quiet though and I am not too concerned on the movement. Note - there is not kill switch for the axis movement on the extremes, so the PEI plate needs to be on the bed when leveling (not like my old SV01). Support: I had an issue right away with the unit when I first received it (mostly my error in comparison to the SV01, mentioned above) and I need to say they were quick in response and assisting with the issue. Truly a fantastic and responsive support system in place. I will also say the SOVOL community (official and non) as well as the 3D community as a whole, have been a delight over the years in helping with troubleshooting and assistance. Overall, a solid machine, does the job, and would highly recommend.

The SV06 Plus is a near perfect 3D printer for beginners to advanced users. I have the Ender 3v2, Ender 5 Pro and Biqu B1. This has quickly become my favorite! At 300mm X 300mm x 340mm print volume you have plenty of real estate for most projects. It doesn’t take long for the 235mm X 235mm bed size of the beginner Ender 3 style printers to become frustrating. This is the first of my five printers I have not wanted to immediately start upgrading. It has all you need for a fantastic printing experience right out of the box. Pros: 1. large print volume. 2. Its fast, 150mm per second acceleration. With fine tuning it will go much faster. Switch to Klipper, and use an accelerometer for perfect prints. 3. All metal volcano hot end 4. Direct drive, with planetary gears 5. Dual Z axis motors and drivers 6. Large enough Touchscreen 7. Built in bed leveling sensor. 8. Belt tensioners 9. Filament runout sensor 10. Linear rods for all axis. Although some say not as good as the linear rail, I am pleased with the performance. 11. PEI Build plate There are still many more Pros for this printer, but these are all things I have upgraded on my other printers. Totally ball parking, I would guesstimate I have spent an additional $250 on my Ender to get to a similar performance. Cons: Now for what makes this Almost perfect. First, I always make sure I have the most up to date firmware on the machine from the manufacturer. I then usually update to the most current version of marlin, adjust what I feel is important and load. The SV06 Plus shipped with the Firmware version 1.1.5, the website has a pre compiled .bin file, with no explanation of version, no revision history, so I assumed that to be the absolute latest stable Version, as per most electronics companies standard. I work in consumer electronics industry and this is one of the few companies to ever break that norm. My assumption was wrong, the “latest” firmware version on their site turned out to be 1.1.4, I searched around looking for the 1.1.5, found it on their Github. I compiled it without issue, tried to load but couldn’t get the board to take firmware. I then contacted tech support through Amazon, FB and Email asking for the 1.1.5 firmware. It took 2 full days before I got a response with the attached bin file. I loaded and was printing perfect benchies. So this was 95% my own fault, I should have looked into it more, but I find it ridiculous for a tech company who is fully open source with software and hardware to not have the basic labeling and revision history clearly explained and posted!! Sensorless homing for x, y and z. I know it works, but the sound and mild “violence” of it hitting the physical limits for the sensor-less homing to kick in bothers me. The biggest issue with the printer is the filament runout sensors mounting bracket placement. Although it works, there is considerable friction as the Direct drive pulls the filament through. It has not cause any miss prints or under extrusion yet, I feel it will eventually lead to a printing problem. It is nothing 10 minutes in CAD and 20-30minutes printing cant fix. I have seen many poor reviews of this printer both on Amazon and other social media platforms, I cannot help but feel all those reported must either be new to the hobby, or possibly Sovol had a QC issue at some point that was resolved prior to my purchase. This printer is much, much better than the 4.1 stars it currently has. If you are unsure, I would advise you to just buy it. The only thing I would say about buying it right away is wait until you it on sale. I picked mine up during July Prime Day sale for $299. I have seen it this price a few times since, as long as your not in a hurry, $80 will buy you a decent amount of filament.

I purchased this, my first 3D printer, on a Black Friday deal and opened it on Christmas. It is indeed very easy to assemble. The top gantry is pre-assembled and you only have to screw it to the bottom frame. As soon as I put it together I saw the top of the gantry was installed upside down (attached picture). I contacted support but got no answer for a week at which point they gave instructions to fix it myself. Still since the error was obvious I was becoming nervous about the quality. I fixed the gantry and got some good quality prints. Then it started printing poorly. Sovol pointed me to their Facebook group. Going through the posts I discovered the problem I was seeing was caused by the X axis not being level. There were posts to adjusts this but they included a warning that even if levels it likely wouldn't stay fixed. That turned out to be the case with mine. After a few good prints the quality problems returned and the cycle repeated. Unfortunately the return window had closed by then. I repeatedly spent hours try to get decent prints and gave up. What I learned. Don't buy a Sovol printer because the factory has poor quality and their customer service is slow and documentation sparse. I learned I really enjoyed 3D printing. So I bought a more expensive printer that has a great reputation for quality and service. I've been using it virtually daily with no problems at all. Giving up on the Sovol was the best decision. 3D printing is no longer a frustration and is instead a delight.

Background As a field service technician with nearly a decade of experience working on industrial CNC machinery, I have extensive knowledge of precision mechanical systems. I’ve been using the Comgrow T300 3D printer for four months, and this review reflects my experience with its performance and reliability. Initial Impressions The T300 is marketed as a budget-friendly 3D printer with a large build volume, but its reliability has been disappointing. Despite my technical background, I’ve encountered persistent issues that have made this printer frustrating to use. Issues Encountered Y-Axis Tensioner Failure: On the first day, the Y-axis tensioner snapped. While Comgrow sent a replacement part, it took weeks to arrive from China. I designed and printed a replacement myself, rendering the shipped part unnecessary. Y-Axis Layer Shifts: For prints longer than 5–6 hours, I noticed significant layer shifts in the Y-axis. After troubleshooting, I determined the stepper motor was overheating, losing torque, and missing steps. I upgraded to a stronger stepper motor, added a heat sink and fan, and reduced max acceleration to 3000 mm/s² and print speed to 80 mm/s to prevent overheating of the motor and driver. Extruder Tensioner Failure: Shortly after resolving the Y-axis issues, the heated insert in the extruder tensioner failed. I purchased a new tool head from Comgrow, which was easy to swap since it’s sold as a complete unit. However, the PTFE liner in the new heat sink was warped or crushed, preventing filament loading. I reverted to the original hot end, managed one successful print, and then encountered further extrusion issues that remain unresolved. Ongoing Reliability Problems: The T300’s stock components, particularly the tool head and electronics, have consistently underperformed. I’m now planning to replace the stock tool head with a custom Stealthburner setup and may overhaul the electronics entirely. Performance When Functional When the T300 works, it produces high-quality prints with good detail. However, achieving consistent performance requires significant modifications and constant troubleshooting, which is unacceptable for a consumer-grade printer. Pros Print Quality (When Working): Capable of producing detailed prints with proper calibration. Large Build Volume: Suitable for larger projects, a plus for hobbyists. Affordable Price: Competitive for its size and feature set, though reliability issues diminish this value. Cons Poor Reliability: Frequent hardware failures and overheating issues. Slow Support and Shipping: Replacement parts take weeks to arrive from China. Subpar Components: Stock tool head and electronics are prone to failure and require upgrades. Time-Intensive Fixes: Requires advanced technical knowledge to maintain functionality. Final Thoughts The Comgrow T300 3D printer has potential but is plagued by unreliable components and frequent failures. While it can deliver good print quality when operational, the constant need for repairs and modifications makes it a poor choice for most users. Even with my extensive experience in CNC systems, I found the T300’s issues excessive compared to other 3D printers I’ve used. Unless you’re prepared to invest significant time and money into upgrades, I recommend looking at more reliable alternatives.
