Top Amazon Reviews
Size: T1 Pro-1000mm/s
Color: Flsun T1 Pro
Because Amazon groups the reviews together for several products when you can select a "style", it is important to lead off with the fact that this review is for the T1 Pro. I'm a hobbyist 3D Printer - I have no desire to set up and manage a print farm or consider the numbers for profitable sales or what have you. I have been running everything on a semi-reliable Voxelab Aquila (an Ender 3 clone) since 2022, but I was beginning to get tired of the bed leveling every other print, and how slow it seemed to be getting (prints typically take about 30% longer than estimated, in fact) and the fact that I had no reliable enclosure for it which was costing me bed adhesion in the worst case and leaving me with curled models in the best. It was time for an upgrade, and I spent a lot of time picking out a replacement. I hope you'll forgive me for the length of this review, but I've come to notice that, at least on Amazon, 3D printer reviews are starting to be lackluster. Users deduct stars for the slightest inconvenience, and in my opinion, that's just not how things should be. These machines are... Well, *machines*. They aren't overly complex from a hardware standpoint, and if you want to enjoy printing, you're well served to learn how these machines work. For that reason, I really hate to see when people complain that a printer doesn't come to them pre-constructed and ready to go right out of the box. Is that convenient? Of course. Is it fun? Most certainly. Does it help you learn? Not at all. I bring this up because I've seen a lot of warnings and strife over the fact that this printer needs to be assembled. It comes in as flat of a pack as possible (presumably to keep shipping and storage costs low) and is in about 16 pieces, depending on what you consider a "piece". The end product is a 3 foot tall behemoth of a printer that weighs approximately 40 pounds and has very few places to grab it once it is done. The only warning I have for you involving this is to build it where you want it to stay because it's a pain to move. It took me one hour and thirty minutes to build this from unboxing to functional, with an additional 20 minutes to put the door and acrylic windows onto it. The only difficulty in the entire build was assembling the actual print head, as you have to attach the arms to the hot end with small pegs that slot into small holes. The pegs are attached as universal joints and will move all around on you, and the arms, connected as pairs of two (6 total "arms") by a strong spring, have to be pulled far enough apart to actually slot in. It takes a great deal of force and effort to accomplish this, but once you get the first side in, it gets easier. I would recommend two people for this task, one to pull the arms and one to hold the hot end, but I was able to do it by myself so if you're short on helpers, it's possible. Aside from that, the most time consuming part of the build process was how fiddly some of the pieces were to get fit together. It took some doing to get the screws to line up in their connection points on the three "walls". There is a part where the instructions tell you to remove a cover from one of the walls to do some cable management and getting it back on was a hassle. The instructions are clear and easy to follow but you can tell the pictures are very generic to be able to cover all the models they produce. I'll offer up the only point of comparison I have in this area: the aforementioned Voxelab Aquila, which also came disassembled. The build process for the T1 Pro is at least three to four times easier. The extruded aluminum frame of the Aquila required inserts to be slid into the grooves for the screws to set into which took time and precision to get lined up correctly (and it *needs* to be lined up correctly), the limit switches had to be manually adjusted after installation, the belts had to be installed manually, the worm drive had to be greased up - long story short, it was a *project*. NONE of this is present in assembling the T1 Pro. The steppers and the belts they drive are pre-installed on the walls. The walls slide into place and are held stable before you even screw them in. In my opinion, you could not ask for an easier build process so the fact that reviewers treat this as a negative is baffling. Now for the finished product. First off, we'll discuss the cooling fan. You can't read a review or watch a video without people complaining about the noise that this fan produces, so let me say that unless FLSUN has installed a different fan in the months since initial reviews came out, these reviewers must live in absolute silence all the time, or have some kind of animal super-hearing. At full blast, printing the included 10 minute Benchy, I was able to sit directly in front of the printer watching it deposit filament at unethical speeds and carry on a conversation with very little need to raise my voice. I was prepared for the absolute worst, it had been compared to a vacuum cleaner. My response: I want whatever quiet vacuum cleaner that reviewer has. The bed is stationary, which should come as no surprise but is a different world from what I'm used to with a bedslinger. There is an auto-level function but since the bed is stationary and has no tuning knobs, I presume it's leveling out the print head to compensate for any drift. There is an included LED light built into the same wall that the instructions tell you to plug the camera into, mostly to provide backlight for the camera, but aesthetically it makes the printer look cooler than it already looks. The included camera is USB type C, and has a cable that is ten times longer than it needs to be. I shoved the excess cable into the hollow space under the rail where nothing travels. I have not used the wifi functionality yet to watch my print through the camera. Form wise, this thing is tall. I mentioned the size earlier and it hasn't gotten any shorter as the review gets longer. A lot of the business portions of the printer (stepper motors, cooling fan, limit switches, filament) are housed up at the top but surprisingly it doesn't seem top heavy, which is good engineering on FLSUN's part. Since it's tall, you'll probably want to put it on something low lying, and since it weighs quite a bit (the measurements say 47 pounds!), whatever you put it on better be sturdy. I wish it had some handles somewhere, since moving it is a hassle. I'll say that what I am not at all a fan of is how the filament is contained. There is a rather primitive locking system at the top similar to how you would lock a bathroom door at a very aged gas station - this metal dowel runs through your filament spool and keeps it in place floating at the top. I use 1kg spools and they feel like they just barely fit up there, and I'm not a fan of how the fan tubing gets in the way of the filament. The current setup I have has it passed in front of the filament spool and while it doesn't catch, I have to worry about friction given that this seems to be CPAP tubing and looks very delicate. There is a hole in the top of the housing for passing filament through from outside of the printer, and I might end up looking into something to do that instead, purely because of how worrying the intended design looks. I mentioned the speed earlier as "unethical" and I'll stand by that statement. The advertisement is real, this thing really does deposit plastic fast. It's mesmerizing to watch and the noises it makes are fantastic - it feels like the future. It comes up to temperature lightning fast, too. It can't maintain that 1000mm/s all the time, but it does seem to average out to 600mm/s, which is just insane. The time estimate that Cura has given me on some of my prints have been more than halved since swapping settings over to this machine - as I print more, we'll see how that goes. It is fully enclosed with minimal gaps, so I doubt there'll be much issue with poor bed adhesion due to something ridiculous like the air conditioning coming on. Build volume is a factor that needs to be discussed since by the nature of the delta style, you don't get the height you would suspect out of a machine this tall, at least not as a cylindrical volume. The round build plate does mean that you get the full width in any direction, but it also means that things that come close to the max width have to be printed one at a time rather than side by side like you could on a square build plate. This is probably not an issue for most people. It's neither here nor there, but while the top of the machine is obviously well defined - the carriages hit the ceiling and cannot go any further, the "bottom" seems to be where the build plate is rather than where the track stops. I'm not going to try it any time soon, but it looks like one might be able to fashion some kind of extension for the bottom and possibly get more height out of the printer... But that's just a casual observation. I could be dead wrong! I dig the touch screen, it is responsive and easy to navigate. Some options are displayed as pictures and not words - these may be elaborated on in the digital manual that I have not taken the time to look over. It is very interesting that the printer itself seems to be able to hold files, and I like that it uses a regular USB slot over the micro SD slot that was present on the Aquila - I don't mind having to use a converter but I've met plenty of converters that don't work but never met a USB drive that doesn't. Overall, this feels like money well spent, especially considering the price of some Core XY offerings out there right now.

The media could not be loaded. The FLSUN T1 Pro is an impressive 3D printer that offers phenomenal speed and decent performance. Assembly was straightforward, and the auto-leveling system worked well right out of the box, saving a lot of setup time. The large build volume is perfect for bigger projects, and the print quality is consistent once you get the settings dialed in. One of the standout features is its speed—it prints noticeably faster than many other printers in this price range, without sacrificing much in quality. The touchscreen interface is intuitive and responsive, making it easy to adjust settings and monitor progress. While it’s not completely free of minor quirks (its print speed can sometimes be TOO fast), the T1 Pro is a reliable and efficient choice for hobbyists and makers looking for a fast, delta-style printer.

This is a fun printer. Delta type printers are so fun to watch. It took about an hour to put it together and leveling was super easy. Still working on calibration, but here is a nice little castle print with silk gold PLA.

The media could not be loaded. The Flsun T1 Pro is a very nice machine for someone looking for a fast, efficient machine! If your looking for a speedy delta style printer I don't think you're going to find a better machine! I love the design of this printer. The printer is very fast, I ran a few test prints and honestly, I would say this is by far the fastest printer i have used to date... The instructions are very clear, the user interface is amazing and easy to use. I was able to get this printer up and running withing a few hours, the hardest part was the anticipation of getting this beast running! The printer was well packaged and all the included pieces where well thought out. Assembly took a few hours, maybe 3 at most, I wanted to make sure I got all the bolts tight. I was able to print 2 or 3 things also in that 3 hours, I was testing some settings out. The Flsun printer is very quiet compared to other printers. I have printed a few large scale prints and barley noticed it was running. This is a vast improvement to prior delta printers! This printer will serve you for years to come and more, it is very well thought out and engineered. Thanks so much for taking the time to read my review, I hope it helps you on your next purchase!
