The QIDI TECHNOLOGY i-Fast isn't my first 3D printer. At $2499 (at the time of this review), it's pretty much the same price as the Ultimaker 2 (since upgraded to a 2+) I bought in 2014! Even further back than that, though, my journey started in 2011 with a Mendel RepRap. If you aren't familiar with that particular unit, it was pretty much the early adopter DIY choice - and unless you wanted to get a commercial FDM printer, it was the only option available. Between materials that were not ideal, marginal build quality, immature hardware control, and the bad quality of early slicers, personal FDM was cool, but not for the faint of heart... and certainly not for the plug-and-play crowd. In the years since, the market has developed more consumer-friendly devices - even on the low end. While the Ultimaker 2+ was good for its time, I wanted to explore the "prosumer" chasm between hobbyist and commercial FDM printers. The features I wanted were dual extruders, the ability to print ABS with fewer problems, high dimensional accuracy, the ability to use higher temp materials, and large print volume. The dual extruder requirement narrows the field immediately, and while I didn't want or need dual INDEPENDENT extruders, I desperately wanted to be able to print with PVA. My previous experience with Ultimaker had me check there first, but I was not cool with the prospect of spending $5000 to $9000 on a printer. Obviously, YMMV if you have commercial aspirations for your prints, but it didn't make sense to me. QIDI kept showing up as a vendor of interest for me... the printers were financially feasible, appeared to be made well, and had mostly good reviews. It was really down to the QIDI i-Fast or the Raise3D Pro2 (the shorter one). The i-Fast arrived a few days after I placed the order. The shipping box was MASSIVE. I got the box into the house and decided to uncrate it right in the front hallway. Since the box was essentially the same width as the door leading down to my basement, I didn't really have a choice. The upside to the unboxing was that the printer is marginally lighter to carry down by itself. However, it's still 90 pounds and awkwardly shaped - fortunately it has molded carrying "dents" on the sides of the printer. The unit was extremely well packed, and nothing was damaged in shipping. Conveniently, the printer arrives almost entirely assembled. I looked for the spool holding hardware, power cord, etc. and immediately felt dread - I had pieces missing! The instructions clearly show where the extra hardware goes in to one of the styrofoam cutouts - and I didn't have anything there. The crisis was averted 5 minutes later when I realized that those parts were stuffed into a filament box. I had naively assumed that the filament box contained, you know... filament (like the other included filament box did). Yeesh. Once everything was together, I looked the unit over. Notably, it completely dwarfs my old Ultimaker 2+. It also has a much more professional look to its build quality, aside from the cheesy "i-Fast" sticker. It definitely looks more expensive than it is. It's nice that the i-Fast LOOKS good, but that's not really why you get an expensive FDM printer, is it? First, I dialed in the Z gap. Then I loaded the included red PLA plastic and tried a test print. Finally, I loaded some of my own plastic into the other extruder and tried the extruder alignment print. I ended up doing it twice, since I had to confirm the offset. With that done I was less than 30 minutes from having unboxed the printer, and I was ready for my first real print on the i-Fast. I used PLA, TPU, and PETG without any issues. In fact, printing with the i-Fast was everything that I'd HOPED the Ultimaker 2+ would be year prior. It's truly plug-and-play. Prints are amazing, even when using .2mm layers. I had some issues with ABS and PVA, but that's only because I'm relatively unfamiliar with the temperatures and speeds. Once I got that figured out, those were perfect, too. The whole experience taught me quite a bit. I don't really use PVA unless I need a COMPLETELY clean floating surface. My experience with supports on the i-Fast is completely different than with previous printers, as thin or tree supports release so well, that PVA is largely unnecessary (which is a weird admission after I wanted dual extruders so much). Using both extruders adds a LOT more time than I expected, and you will really want/need to use an ooze shield and/or prime tower. The layer start/stop point is very pronounced with this printer - it's not a complaint... just an observation. Other observations? Well, the printer is pretty fast. That was a surprise to me, because I generally think of printing in terms of material flow rate, which is the same from printer to printer (assuming the same nozzle size, anyway). All that's left is the transit speed, right? Well, I just assumed that all printers were doing it at 100mm/s (or close). Nope. Also, the printer is pretty quiet. With the top cover on, which you are only supposed to use for specific materials, the printer is VERY quiet. Otherwise, it's still quiet, with most of the noise coming from the extruder head clunking around. Good vibration isolation, like larger neoprene or rubber pads under the unit can cut the noise further. The i-Fast was my first printer with a spring steel print bed (I've since gotten that feature on an Ender 3 S1, too). Wow. It's a massive quality-of-life improvement for print removal, and I recommend it to EVERYONE. The slicer just looks to be a rebranded Cura, but fortunately it's updated pretty frequently. I like the i-Fast quite a bit, which makes the deficiencies stick out that much more. Initially, I noticed that the documentation didn't seem to be quite up to the high level of the build quality and packaging. There are also other attention to detail issues, like misspellings on the BUILD PLATE! Those aren't the end of the world, but they are small, unforced errors that detract from the credibility of the end product. The largest misstep, in my opinion, is the location of the USB port. It's RIGHT next to the door. It's so bad that I immediately bought a small USB extension cable that has a right angle at the male connector. That allows me to keep the thing as low-profile as possible, and relocate the plug-in location for the flash drive. The ergonomics of the touchscreen and device's UI are just ok... QIDI could really improve functionality here, including the ability to easily bring extruder temps up for loading and unloading of filament when not in a print job. $2500 was a lot for me to spend on a piece of hobby equipment, and so I've been scrutinizing the value proposition since the i-Fast arrived. My opinion is that the QIDI i-Fast is an excellent FDM printer for anyone that wants to produce flawless prints without having to become an expert in FDM printing. Even though there's a camera on the unit, I know that I don't have to look at the thing throughout the first hour of the print to make sure that it doesn't detach from the base plate. I don't have to worry about coming downstairs and seeing the plastic Silly String of a failed print that continued ALL NIGHT. Instead, I know that I'll have a perfect print waiting for me. Highly Recommended

I run a design consultancy and do a lot of 3D printing of prototypes for my clients. Most of which are “proof of concept” prototypes just to make sure everything is good with the design before I send the files off to manufacturing. I am giving this review not to rate this printer for making dragons and figures out of PLA and PETG. There are many hobbyist printers out there for that kind of work. I am reviewing this printer as a professional mechanical designer of two decades and its ability to serve my need for engineering grade prints. ABS – After wasting many years playing around with PLA, PETG, and some of the other hobbyist filaments, I quickly realized that if you want 3D prints that behave like production parts, then you need to print out of ABS. It is strong, it bends, it does not crack, and it gives you a great representation of that an injection molded part in production will be like. After all, 90% of the plastic parts you see in this world are ABS. Why not use it as a prototype material? When printing ABS, you need a ventilation system and a fully enclosed chamber to prevent warping. This printer and it’s little brother (the X-Max) both print perfectly in ABS. I have never had a corner peel up, I don’t get the strange elephant foot problems, and it just works. Plain and simple. ABS is now my house filament. I purchase the 10lb. rolls and run hours of it on this printer and my X-Max. CFNylon & Nylon – I would say the hottest filament available right now is carbon fiber Nylon. This is an amazing material to be able to use and supply at the prosumer level. You almost can’t see the layer lines, it is strong as can be, and it looks really great! Just like ABS, after wasting years playing around with PETG (which was invented to replicate Nylon) I discovered the big boys print with actual Nylon, NylonX, and NylonG. All of these are amazing filaments, but again you need a fully enclosed printer. The heated build chamber on this printer makes these filaments work just that much better! The standard profile for Nylon in the Qidi software works great and I have not had to tweak one setting. Dual Head Printing – I have been watching dual head printers come onto the scene for a while now. I am familiar with Idex printers, I know how Ultimaker does it, and I have seen many printers have problems and issues. Idex printers are fun if you want to make mirror image parts, or two parts at the same time. I have owned my consultancy since 2005 and can’t really remember ever truly needing this feature. I prefer the way Qidi has approached the dual head design. One head lifts up about ¼ inch while the other one prints. It has a robust mechanical feature that handles this with a small push bar on the print head. This is exactly how Ultimater has done it for years, and they have a great track record of producing dual head machines. I like the two print nozzles as close together as possible, as it just makes leveling everything that much easier. Qidi now offers (for free) an optional two head metal hot end that reaches 300 celcius. This is HUGE because now you can print ABS, Nylon, and TPU with dissolvable supports. This is a game changer for me. Now I can print beautiful Nylon and ABS parts without all the post processing time of removing supports, worrying about support scars, print orientation and all the headaches that come with supports. Quality Build vs. Bed Leveling – I hear a lot of people complaining about printers that do not have an automatic bed leveling routine or a BL-touch built in. Here is the thing. I learned this with my X-Max. If you truly have a rock solid well build machine like the I-fast or the X-Max, you really only need to level the bed once in a great while. To confirm my print beds are level, I print a test print that is 5 small boxes that are only one layer thick and on each corner of the build plate with one in the center. This is the best way to tell if the bed is truly level from one side to the other. With this printer and my X-Max. Once I got it set the first time, I have never had to worry about bed leveling. This is because the Qidi printers are bobust and bult like tanks inside. The I-fast has rail sliders like you would find in expensive CNC machines. It is not full of cheesy 3D printed parts like other printers out there. This has metal components, injection molded parts, clean wiring, and similar build quality to some of the super expensive machines like Stratasys. In my opinion, if you need to level your bed before every print, then your frame rail structure is likely not holding square and true. These kind of problems don’t even exist on the Qidi machines. TPU filament – I have been printing for 6 years and have had a lot of 3D printers. I had all but given up on printing TPU, as I just could not get good prints from any of my machines. With TPU they recommend a direct drive, and the slicer settings can be really tricky. The I-fast with the standard TPU slicer settings is amazing! I have printed flexible bottles, grips, over-molded parts, and have had amazing success. Removable Build Plate, Wifi, and camera – What can I say, the removable build plate is amazing. You get two of them, so you can always have one at the ready and one that you can clean later. Not only does the Wifi work perfectly, but it works right out of the Qidi software. Just slice and hit the print button. You don’t need to shell out to some crazy print que platform. It is a click away. I have no issues with it dropping off or trying to manually enter it with an IP address. It just works as it was intended. The camera, same thing. This was a surprise as I did not remember reading about it in the spec. sheet. There is an app for your smart phone and you can literally watch and monitor your prints from anywhere. In conclusion; If you are a designer or mechanical engineer. If you have had your eye on the expensive high temp machines and just could not afford them, take another look at the I-Fast. It checks all the boxes for a commercial grade engineering grade 3D printer at a fraction of the price. This is my second Qidi printer. I purchased the X-Max two years ago and it is my favorite printer. When this one came out, I just bought it immediately as I knew it could only be that much better. I was correct in trusting Qidi. They have delivered an amazing printer and I plan to use it a lot!
