CrealityK1 Max 3D Printer Official, 600mm/s Max High-Speed 3D Printers Large Printing Size 300x300x300mm with Auto Leveling, Dual Cooling, Smart AI Function, 32mm³/s Flow Hotend and Out-of-The-Box

This is the Rolls Royce of 3D printers. Very tough, very accurate and pretty quiet too.A few downsides: Can’t print TPU or PLA so no flexible material or dissolving supports (print head design means both clog easily). Mine was slightly damaged in shipping - probably because they are so fanged heavy - but works fine so I didn’t get it replaced.Now the upsides: Auto levelling doesn’t really cover it, this does auto everything! From calibration is about 15 different aspects to having cameras that can be set to pause jobs of problems occur (such as broken or empty filament It will carry on automatically from another matching spool too; great for using up all those leftover spools. You can monitor and print remotely (only clearing the bed of a print job and loading new spools need your actual presence).Chamber and hotbed heat to high temps and carbon reinforced materials are fine with the hardened steel nozzle - it comes with a spare - and a pretty good toolkit!

Rarely gets to it's full speed, few fast printers do. But it definitely races along at a fair whack and makes a bed slinging ender 3 look and feel ancient. 8 hair prints on an ender 3 are down to around an hour. Stuff I would never print on an ender 3 is within reach on the k1 max. Good print quality, built in bed levelling via a lidar, inbuilt camera is OK, not stellar but usable. Filament runout sensor built in. It does timelapse on every print, though I haven't worked out how to delete them. Prints over local WiFi, so a bit octoprint like as you can send your files over WiFi instead of using a USB stick, though that USB option is still there if required. Using a USB stick you can also pull timelapse videos direct to the USB stick. Biggest downsides of the k1? No cura profiles at the time of purchase so stuck with creality slicer. Creality slicer works fine but is limited with only 3 profiles, basically high quality slow, medium still slow, and average quality fast. Options are intuitive in creality slicer. Considering it is basically cura they make things difficult when they shouldn't be. You can monitor prints over WiFi, but for me it can't be done from the program itself on the pc, I have to copy the ip address (there is a copy ip option on the print screen so they obviously planned for this issue) to then paste in a browser window which then works fine. If you use a trackball or mouse without a scroll wheel you are in for a miserable time adding custom supports as I cannot find an option to zoom in on the model without that wheel. The only thing to truly HATE with this printer? The phone app. It is full of ads. Ads on ads, ads everywhere. The app is basically an ad app with the printer options you want to access hidden in amongst all the ad misery. Simply put, do not use the phone app if you value your sanity.

Great 3D printer, works straight out of the box, just follow the instructions and on screen prompts , it's touch screen menu system, wifi or USB stick for models

I struggle to understand how Creality can make a product which sounds like an aircraft jet engine all the time and think that is accceptable! As soon as it's powered on it sounds like a jet engine at idle, with just the PSU fan running, and then if you dare to start printing then the main fan ramps up to 100% and it sounds like a jet engine about to take off! Combined with the fact when running at normal print speed it is so violent in its movements it shakes and vibrates, and when it's doing its calibration there is some horrific vibration from the underside panel as the printer winds up to full speed, it is just incredible that the Creality engineers think this is acceptable! It reminds me of PC building 30+ years ago, where we all had 20 fans screaming in our ears to cool our overclocked Pentium processors at 450MHz, and now we have PCs running at 5GHz which are entirely silent - this printer is the equivalent of the 30+ years Pentium cooler in an age of 5GHz silent PCs. Cooling technology has moved on HUGELY, so why build something using 1990s tech in 2025???Yes it's beautifully built, and the self-calibration seemed to work well, but I managed 1 print successfully before my second print clogged and after 30 minutes I returned to see it printing nothing in thin air (and had been since I would guess layer 2 or 3)! Ironic that that second print was for a 5015 fan shroud in the hope I could quieten down the main hotend cooling fan. In a room with the door closed I could still hear the K1 SE in the next room...I was looking for an upgrade for my Ender 3 S1, and to be fair the S1 was pretty noisy out-of-the-box so I spent a lot of effort getting that to be quiet with revised hotend and PSU fans, and there is no question the K1 SE is substantially faster (4x easily) but the noise (and heat) is just unbearable so I'll take slow and quiet over fast and insanely noisy!!Additionally it doesn't support the AI camera (there is no wiring to plug it into), despite the AI camera stating it supports the K1 SE.Overall I had no option but to return it!
