Creality Ender 3 Max Neo 3D Printer, CR Touch Auto Leveling Bed Dual Z-Axis Full-metal Extruder Ender 3D Printer Large Print Size 11.8x11.8x12.6in

I now have three Ender 3 Max Neo printers and they are fantastic! Solid and reliable. There are several MUST have upgrades that you need to do up front to get them to a higher level of quality.First, get rid of the glass bed. Get a PEI sheet and be done with it. Prints stick better and are much easier to remove.Secondly, get rid of the stock PTFE tubing and get some Capricorn tubing. The stock tubing inside diameter is too big and causes a lot of play on feeding and retracting the filament. The Capricorn tubing has a much tighter tolerance and higher heat resistance. Because of it (and the third reason below) I can now print with TPU and a lot less under/over extrusion issues. It is made from a material which has a higher heat resistance and has less friction/resistance so the filament moves more easily through the tubing.Third, get rid of the stock heat break and get a bi-metal one instead. The stock heat break allows the PTFE tubing to sit directly on the printer nozzle which cooks the tubing and will cause nozzle clogs and burnt filament. Even with Capricorn tubing it begins to break down fast over time. With a bi-metal heat break the PTFE tubing never touches the print nozzle and is cooled much easier so no more replacing the tubing. Due to the tight tolerances of the bi-metal heat break (and Capricorn tubing) your retraction settings will change so make sure to run some retractions test prints.Lastly, not needed up front but it will need to be done, replace the brass extruder gear with a steel unit. The brass extruder gear is softer on the filament but tends to wear out faster which can cause some under-extrusion issues. My first Ender 3 Max Neo that I bough was starting to show signs of wearing down after around 200 hours of printing. I have since replaced them all with steel gears and no issues since. Make sure to calibrate your E-Steps after replacing them as it will change due to the change in gear diameter and teeth count.Overall these are great and highly underrated "medium" size printers. Again, I have three of them and do not regret buying them, really great workhorse printers once upgraded!

I've been printing for almost 10 years. I've worked with just about every medium and every type of project you can imagine - from space to farming. I had the luxury of working with an n-Scrypt 300dn printer about 8 years ago to give anyone interested a reference.This printer has every upgrade we needed and recommended on the 300dn back in 2016-19. The 300dn was approximately $1M.We spent months fine tuning and developing applications (nano engineering) on the 300dn - and I give a slot of credit to my development as an engineering and designer to my work with that great printer.All that to say.....you better listen to me.The Ender - straight out of the box - is one of the easiest, highest quality printers I've encountered. HANDS DOWNS.I was printing (with really exceptional quality and scale) in minutes. Not hours. Not days. Not weeks. Not months. Minutes.Overnight, I've already printed 3 projects and I'm throwing caution to wind with this AWESOME printer! I'm about to start printing press brake tooling with this printer! I'm really impressed and you will be too! Too many bell and whistles to name. And if you've got $400, you we got yourself one. For $550, you could get the bundle and other accoutrements and go full fabrication mini-shop right at the startup!You better listen to me. I'm sure there are others out there - not even interested right now. The only thing I can say that I don't like was something I knew going into the deal. The max speed is 150mm/s.But......I'm sure I could upgrade this build to do whatever I want within the limitations of the structural design. But I could probably improve that if I wanted to.Point in all this. Banner call for all printers - this is a fantastic printer and you'd do well to invest in this product for your small to mid size project enhancements and other self-driven solutions!Happy Printing!
