abunda_amazon_reviews You might be able to assemble this printer in a couple of hours but you can't build it in that time. There is a significant difference in building something correctly and assembling it. Assembly is the easy part, anyone can throw things together. The build is now complete and to do it correctly takes 4 to 5 hours. When you stand the Z axis uprights on their ends on a granite surface plate it's clear that the ends aren't machined square. After machining the ends they are square and flat enough to assemble now. The Z axis bracket that the leadscrew nut bolts to was not fully bent so the leadscrew didn't line up with the coupler and had to be straightened to make it parallel to the Z uprights so it would line up with the coupler. Check yours to make sure that bracket was bent at 90 degrees. The two uprights had to be shimmed to get them square to the bottom supports and parallel with each other so that the X axis rail would go up and down in a straight line without binding. Colored plastic shim stock of various thickness and an accurate machinist square is paramount to your success here. Even a small Framing square or a plastic triangle from an office supply store would assist in getting the uprights square to the base. The two uprights have to be parallel to one another and hopefully square to the base in order for the top rail to mate up correctly. If you want accurate prints the X and Y axis has to be able to move squarely to one another. The Z axis has to move perpendicular to the build plate once the X and Y axis are square. If this isn't accurate it will affect your print quality. Once the mechanics are built you will need to tidy up the wiring, check the hot end and build plate heating and make sure the extruder will extrude plastic from the nozzle. Prints can be made directly to the build plate, to a piece of borosilicate glass, mirrored glass or tempered plate glass resting on the heated bed. Once the Z stop is set close so that the Z homes with the nozzle close to the bed plate the you can level up the bed plate with a stainless steel feeler gage and you should be good to go. I would use a .005" feeler gage to start as a comparable piece of paper is .004" thickness. Summary: Pros: 1. Good value for money. 2. Everything bolted up and worked 3. Spare parts were a nice touch and much appreciated. 4. Good selection of software to slice and handle STL files. 5. Fastener quality was good enough to get the job done. Cons: 1. Instructions are abysmal. The illustrations are too small, not well explained and the references are sorely lacking for someone that has no experience with building small CNC type electronics. In short the instructions are just enough to get the job done but the neophyte will struggle. 2. Build photos would be a big help. You can't depend on a bunch of folks on the Internet to cover your failings with YT videos and websites that may be doing it wrong to start with. The factory needs to own it. 3. Use a full size SD card. Micro SD cards are OK for phones and tablets because they get installed and stay installed, they have no business in a 3D printer they are simply too small to use all the time. 4. The 24V wiring coming from the power supply had insulation nicks on both the + and - wires and had to have heat shrink applied to keep them from possibly shorting out. The screws on the terminal block at the bottom of the power supply were just barely tight so check yours. 5. XT 60 connectors are rated for up to 65 amps continuous but they were never designed to be permanent connections. In RC model applications you may fly for 5 to 10 minutes and then the packs are disconnected. Most of the time the connectors aren't even in use. I would prefer to see a metal enclosure with a terminal strip for the power connections. 6. The uprights are cut on a cold saw and this is a common operation for extrusions. The problem is that the resulting surface isn't flat, straight or square. When you bolt the uprights onto the lower frame they aren't square and parallel. You will have to shim them to get them to be square and perpendicular. Note to the factory; you can do better. Suggestions to Creality: Look at the Pro's and Con's, take note of some of the issues and make corrections to the new kits coming out of China. It takes just as long to do something wrong as it does to make it right. Making it right is easier. There should be an adjustable Z stop instead of a fixed one. The homing speed needs to be lowered slightly as the hot end and table hit too hard when homing. I can do this in the Marlin Firmware but the factory just needs to lower the speed slightly. All in all, this is a great way to spend a couple of evenings and the print quality is really good, especially for the money. Despite the issues this is a great printer. Don't let the issues cloud your decision about buying it. All the issues can be resolved by the builder and that's you. This should be a 3.5 star printer but it could be a 5 star printer with just a little work by the factory.

I would definitely recommend this as a great printer for anyone starting out with 3D printing or even for veterans that want a more compact and reliable unit. I am extremely impressed. Setup The setup was fairly straight forward. It took me about an hour to have it fully setup and powered on. All the tools needed are provided with the unit to complete the full setup. There are a few great youtube videos on setting up that you can watch as well if you need a little extra help. Use Very easy to use. This is not my first 3D printer, so I do have a little bit of experience with them in general. But this was still a very easy printer to simply start using. Leveled the bad, loaded filament and printed the test print. It came out great. My 2nd print with this machine was an Ocaraina from Legend of Zelda. It came out absolutely flawless on this Ender 3. I am very impressed. Like I said, I have had it for a few months now and it has been rock solid. I have not had a single issue. Just load filament and print. I've not even had to re-level my bed yet. Quality The unit itself is very sturdy. The hardware used is good quality. Everything aligns very well. I do not foresee any issues with quality in the future.

This is my first personal 3d printer. I normally use resin based printers at work so I'm used to high quality prints. This printer is able to print at near resin quality if you turn the layer height to .05mm and speed to 25mm/s. I've attached a picture of my very first print (not including the test dog). Obviously resin is going to look better, but for a $250 FDM printer, I doubt you could find a better deal. I ended up choosing FDM over Resin due to the cost of resin.

Phenomenal printer
I purchased this printer a few months ago. It has been a dream to use. I would definitely recommend this as a great printer for anyone starting out with 3D printing or even for veterans that want a more compact and reliable unit. I am extremely impressed. Setup The setup was fairly straight forward. It took me about an hour to have it fully setup and powered on. All the tools needed are provided with the unit to complete the full setup. There are a few great youtube videos on setting up that you can watch as well if you need a little extra help. Use Very easy to use. This is not my first 3D printer, so I do have a little bit of experience with them in general. But this was still a very easy printer to simply start using. Leveled the bad, loaded filament and printed the test print. It came out great. My 2nd print with this machine was an Ocaraina from Legend of Zelda. It came out absolutely flawless on this Ender 3. I am very impressed. Like I said, I have had it for a few months now and it has been rock solid. I have not had a single issue. Just load filament and print. I've not even had to re-level my bed yet. Quality The unit itself is very sturdy. The hardware used is good quality. Everything aligns very well. I do not foresee any issues with quality in the future. I also have a CR-10, so I can stand behind saying that Creality's quality is top notch. Value You will not find a better printer for this price. This printer exceeded my expectations on every level.

Amazing printer for the price. Bed came warped but the seller replaced it
My printer's bed came severely warped. Warped enough that I could not print anything. I contacted Comgrow and they were nice enough to immediately ship me a new bed! After the new bed was installed, it printed like a dream! The only experience I've had with FDM printers is the makerbot replicator 4 and it was a nightmare to use. This one hasn't given me a single problem since the bed was replaced. This is my first personal 3d printer. I normally use resin based printers at work so I'm used to high quality prints. This printer is able to print at near resin quality if you turn the layer height to .05mm and speed to 25mm/s. I've attached a picture of my very first print (not including the test dog). Obviously resin is going to look better, but for a $250 FDM printer, I doubt you could find a better deal. I ended up choosing FDM over Resin due to the cost of resin. It costs around 5x to 10x more to print using resin.

The included belt was too short (problem resolved by Comgrow, see updates)
Everything was appearing to go fine with assembly until I realized that the included belt was too short to reach around the X-axis assembly and attach to the two notches in the hot end assembly. Until I can get a replacement belt, this printer is just a big paper weight. update: August 11, 2018 Comgrow has arranged for a new belt to be shipped to me to replace the defective one. It should arrive in a few days. I'm looking forward to my first print. update: August 14, 2018 The new belt arrived today and I was finally able to finish assembling the printer and perform my first print. The results were far better than I expected. I was initially distraught that I wasn't able to finish assembling the printer, but Comgrow quickly sent me the replacement part that I needed to get things up and running.
