I have owned, designed and built many 3D Printers. There are some key factors that can really affect your prints. To name a few these are things like frame rigidity, belts tension and extruders. The QIDI X-One is a great example of an “out of the box” 3D Printer, but we all know that truly does not exists and here’s why.
The QIDI X-One is built with an all metal frame and is rock solid. There are some well thought out features like anti-vibration rubber feet and mold injected bracketry that is designed in a smart way. The really nice thing about the QIDI X-One is that is comes pre-assembled and ready to print. Just load your filament and perform the bed level procedure to start printing.
The X-One comes with a 3.5” Touch screen that has a really clean interface and is simple to use. The free slicer software (cura) that comes on the SD card even shows you a preview of the model when you select that stl file.
The mainboard is a new 32-bit 3D Printer Controller which is a Chitu F Model v3.9. This runs a custom version if repetier-firmware. 32-bit boards are supposed to offer better processing power and improved printing. However, I think this is overkill for a printer that only has a build volume of 5.5”3 and the board is closed-sourced so you have no option to edit any settings.
The 140x140x140mm build plate has a heated bed and prints rest on a thick MIC-6 Cast sheet. This is a quality build plate and very durable. The X-One also comes with a pre-installed sheet of tak paper for your prints to stick to.
The X-One features an MK10 direct extruder that is very similar to the Wanhoa extruders. There is a short length of PTFE tubing that runs from the entry of the throat down to the nozzle. This is housed by a metal cover that has a Bowden style connection at the top.
QIDI Tech has some of the best customer support I have ever experienced. I have owned and operated $20K 3D Printers and have not received better service than QIDI Tech. You can rest assured they will support you if you have any questions or run into any problems.
Suggestions for improvement
First of all why oh why did QIDI Tech choose a closed source 32-bit control board! My guess is they wanted that cool touch screen lcd. The problem is the user has no ability to PID Tune (much needed), Upgrade Part or Dial any settings in the firmware. There’s no reason to run a 32-bit controller on such a small cartesian printer. I see some really good swap opportunities with the MKS Boards or any other open source one as well. I could care less about the screen and most 3D Printer users are moving to Octoprint or other remote printing solutions.
My next suggestion is the extruder. Why the heck didn’t they make this a Bowden style! There’s already a tube guiding the filament and the build volume could have been increased by having a Bowden style hotend. The direct drive hotend frequently jams at the PTFE Lining and it’s a real pain to get to. Even loading the filament can be a hassle if you don’t straighten it out nicely. I recently upgraded to a Micro-Swiss all metal MK10 hotend and so far, there has not been a single jam. I highly recommend this change and you’ll wish you had the upgrade after you fix a couple of jams and drop your screws down into the printer through the exposed openings. *Tip (Use Blue Tape and cover the openings)
I would consider a Bowden Conversion or possibly a Titan Aero upgrade to get around some of these extruder issues.
Lastly the injection molded brackets are sized for a smaller linear bearing. These are loud and annoying. It would have been nice to upgrade to the IGUS bearings but they just won’t fit. Maybe someone can design some new brackets as there is plenty of room for standard LM8UU size bearings. An enclosure would have been nice but printing PLA you’d have to print with the door open as it would be too hot. But it prints ABS well.
Overall this is one bad-ass little printer with a ton of upgrade potential. You can also find them used on eBay as beginners and lazy people get frustrated with the issues and list them for cheap. They should have read our blog… But if you can’t find them used then buy em new and know that you’re in good hands with the QIDI Tech support and the many upgrading options ahead.
