I bought this on a whim, a friend said he wanted this printer and it sat open in a tab on my computer for a few months before I decided to go for it. I've wanted one of these for years but wanted to wait for a while for the tech/hardware to get better. I didn't want to get something cheap and disposable and from what research I did this seemed like a great deal for the price.If you do get into this hobby, familiarize yourself with SSH clients and commands because you will be connecting to the printer for either maintenance or installing new software to use. It had been about a decade since I've done any coding so it took me a while to catch up and remember commands for SSH navigation. Luckily g.code and config files are pretty straightforward and the macros and commands aren't too hard to figure out if you have any familiarity with coding logic.The company is great and actually cares about their customers, their feedback, and experience. My first time contacting them was the night before my wife went into labor with our first child and I was running on about 3 hours of sleep over a 48h period and I was NOT very nice in my first communications. Annie took it in stride and is still emailing me to check in and answer questions I have as I move on to more difficult materials and more complex software questions. I've had parts break and they have sent me completely free replacements which has been very helpful as I am still new to this and am trying to learn as I go. And with a 1 month old at home money is definitely tighter than it was.I use QIDI filaments and they work great. I've used a few other brands but had issues with quality/adhesion so I stick to their filaments since they make the printer. I got the package and within an hour I was printing PLA items while I went back to work to finish the day. Their included slicer is a great beginner tool and I still use it from time to time but have been experimenting with OrcaSlicer for calibration tests that auto generate, additional settings to tinker with, and being able to slice and directly send my print via WiFi. They are constantly updating their slicer/firmware using customer feedback so I don't seem them lagging too far behind as they grow. I had the printer inside and it was honestly great since I live in a cold, humid area but since I started printing volatile materials such as ABS, ASA, and PETG I moved it to the detached garage. Not the worst thing since all of my tools are in there and they appreciate the heat and the printer helps drive out humidity.The dry box on the printer is a great idea and I've ordered more silica packets since the garage usually sits between 45-65% humidity regardless of the time of year. I typically print one spool at a time since an open roll of filament would probably be ruined if I left it outside the dry box, but I have had a few rolls of PLA I stored in a heated/controlled cabinet (~35% humidity) and when I wanted to use it again I didn't see any issues. The placement of the dry box is a problem for some but I have 360 degree access to the printer in the garage so that hasn't been an issue, although side mounts exist for the box if you wish to move it.Print quality is superb. Some materials will be touchy (ASA has been functional but not perfect for me, which is fine since I'm replacing outdoor fixtures for plumbing/ducting) but once you calibrate your filament, keep up on maintenance, and keep an eye on your first few layers you will find there are thousands of settings and variables you can change to adjust the print quality. I've been printing anything from statues/models to pots, functional items for outdoors, dryer ducting, and parts to enhance my existing tools like my dremel and reloader. The library of models available is huge now which is great, but I have recently been trying to model my own items since I have a CAD license for work and there are just some items you can't find.The volume of the printer sold me and has been great for printing pots for our large garden, or just large items in general. Gluing parts together isn't the worst thing but if I can print something large as a single item it's much less of a headache. Multi-material or color feeds would be great but I don't care much as if I want something cosmetic I will spraypaint or paint with acrylics. Any problems I've had will be found in any printer and I don't blame the hardware for issues. I'm not an expert and can't speak much on the software but I know they use a hard forked custom version of klipper/moonraker. I'm assuming their PCB's are programmed around that and updating might be very labor intense. If you want to you can erase their firmware and use custom firmware on the machine but I don't see any reason to. Also NEVER update klipper or moonraker in the fluidd interface. As I said they have a custom version and you cannot undo an update. I tried for days but eventually support helped me find a new eMMC with the correct firmware installed and a tool for connecting it to your computer for backup/reflashing if anything goes wrong again.Overall, great support, great features, not too hard to learn for someone with 0 experience in this hobby and the issues can usually be fixed. The possibilities are endless and the capability of this printer in particular is great. I plan to use it to print automotive parts, UV and weather resistant items, and many other advanced materials since it has a high heat build plate and a heated enclosed chamber. I wish they would gain a bigger following and be able to grow since I can tell the company wants to succeed and are very responsive to customer feedback. I look forward to continue using the printer and contributing to the knowledge base to help the company grow and improve.

From the moment that the product was unboxed to printing parts for clients, this printer and the supporting service has been A+. The printer was packaged in a way that would make it very difficult to be damaged, using dense corners supports, foam, and plastic wrap for scratch resistance. Nothing was missing in the order, making it super easy to set up right out of the box. One note of concern, which is good and bad, was the instructions didn't always match with the printer. It seems that the manufacturer did most of the assembly work that that users would usually have to do, as explained in the user manual. Of course, I liked that it was less work for me, but they do need to update the user manual to reflect these positive updates. As suspected, nothing was damaged and the unit was squeaky clean.After taking a deeper dive on the machine, in preparation to start printing parts, I did notice a few design/manufacturing flaws, as noted in the following.Issues:1. The top cover did not seat properly, as it was to tight. I could push in 3 of the 4 corners, but had to use excessive force to pop the 4th corner into place. It seemed that the gates used in the plastic molding process were not polished down enough, leaving enough gate material to cause this interference. So, before going "silverback" on the cover, I decided to reach out to Qidi Support, as I had read great reviews on their service support. I will go into more detail on this later in the review.2. The front clear door cover handle had a sharp edge, right were your would grab the handle to open the door. It looks to me like it had been dropped right on that spot prior to assembly. I've added an image of this to the review. I added this to the list of topics to discuss with the Qidi Support team.3. The last issue was that the carbon filter cover did not match what I had seen on the product prior to purchasing, as I really liked the fact that it had this function. I've added a image of the filter cover that came with the printer. This was the final issue I added to the list for Qidi Support to help me with.Qidi Support/Service:Below is how these issues were handled by the Qidi Support team.Let me first say that, just as I had read about, they reached out within 24 hours and were very considerate of the issues I had found, and were very proactive in making these right. The particular Support representative I had the pleasure of working with was Olivia.1. To resolve the issue of the the top cover not fitting properly, Qidi Support confirmed that this was a manufacturing problem that is being improved on future orders. Of course, this didn't help my situation, but it was good to know that Qidi Support recognized the problem and was going to resolve it moving forward. Qidi Support provided me with ways to fix this, by gently sanding down that 4 gates until I get the fit needed. This did work. Due to the inconvenience, they sent me a spool of ABS as a kind gesture.2. To resolve the issue of the sharp edge on the front door cover handle, Qidi Support first confirmed that this also was a manufacturing error that this was a manufacturing error that is being improved on future orders. I did push back on this, as it looked more like damage done during assembly, and did not look like a manufacturing issue. Regardless, Qidi Support sent me a new front door assembly along with a video from the Engineering team to show how to replace on my printer. Along with this, they sent me a print build plate as a kind gesture. With all the items that they shipped to me, they also provide me with tracking information and confirmation of the items being shipped. I received this front door assembly and all items discussed in this review within 1 week. Once the front door assembly was received, I can confirm that this is indeed a manufacturing issue and not from being damaged in the process, as the new door also had the same sharp edge. I was wrong in my analogy (shown in the attached image), but the Qidi Support team took the approach that "the customer is always right". In this case, the customer was not. :)3. To resolve the carbon filter cover, the Qidi Support team confirmed that the cover my printer came with was not the latest design. So, the Qidi Support team sent me the latest carbon filter cover along with a video from their Engineering team on how to install it.4. Bonus from the Qidi Support team was also sending me a improved version of the Type-C cable, which is resistant to high temperature and bending. This is something that the Qidi Support team chose to do on their own, without any request from me. As Olivia had stated several times in our emails..."This is what we should do". It's not often that you work with a company that is proactive in making things right, I really appreciated this level of caring from the Qidi Support Team.In summary, the Qidi Support Team was phenomenal. They are the benchmark for other companies on how to support and communicate with customers. From the perspective of the products quality, it has also been phenomenal. I have printed several components with materials such as PLA, PLA+, and FPLA (flexible PLA). All my prints have turned out great and consistently stable. On as side note, I was overly impressed with the FPLA and it's flexibility for a wrist band I printed. Unfortunately, I cannot share images of this, as it is "patent pending".I hope this lengthy review has been helpful for those that are on the fence with purchasing a 3D printer, or are just wanting to learn about Qidi products and support.Happy Printing,Roy from Sunset Engineers
