Like anything, once you get the hang of it - this printer is great. I’m a newbie and have had the printer for two months now.
My largest complaint about this printer is that it’s loud. Prior to purchasing it I read and viewed videos where other’s were claiming that it was nearly silent. The decibel app on my phone rates it at 71db which equals traffic. The only other thing is that I don’t fully understand the value of the auto leveling function. I understand what it physically does, but I see no better build quality when calibrating it manually or automatically. Actually even when you automatically calibrate it, it still takes a twist or two to get the extrusion perfect. Lastly, I recently learned that the hot end nozzle thread is a unique pitch and replacement tips can only be purchased directly from Creality at this time. So my replacements were purchased ladt week and are on a boat somewhere between China and Seattle. I expect them to arrive in the coming week.
Now for the positives. Amazing build quality, ample controls and a huge print surface that lets you create nearly a 12x12x12 inch object. I’m having really good luck with PLA and PETG materials. I used a couple generic spools of PLA to start with mixed results. Then I started to use 3DSolutech, Polyalchemy and Hatchbox products and found better consistency (settings) and predictable build quality. I use a flexible magnetic build surface and typically run materials from 206 - 214 degrees at the hot end and a build surface temp of 50 - 54 degrees. I was using the stock aluminum surface at 60 degrees. When I got the flexible unit I was baking materials. So I used an infrared bbq thermometer to get a target temp and then played around with the magnetic surface temps until I got similar readings.
I recently had the a build failure on a simple print that was going to run overnight. I’m still not sure what happened, but it broke off the lower fan duct that directs air to the hot end. Lucky there’s lots of resources out there and in 35 minutes I had printed a replacement and was back printing.
If I was more technical I would try and make the unit quieter and upgrade the firmware. But because I’m just learning, I’m opting to stay consistent and use it as is for the time being.
If you aren’t a newbie, I would highly recommend this printer. If you are new to 3D printing, start with the Creality Ender Pro to minimize your investment and take time to flatten your learning curve.
