Hi there, I'm CiCi, a staff of Creality and a close friend of yours.

Yesterday I posted a topic: What's your most unfortunate printing failure?

We received a lot of great responses. Now I'm going to show you some representative comments. Let's check it out!

@Jeff Cheatham: I was running a multi-day print with a brand new all metal hot end. It had been going for around 3 days and I wasn't able to check on it during the 3rd day. When I got been home to check on it, the print had slipped and all of the material was building up around the extruder in a big ball. After extracting the material, I found that the new hot end, the housing, and even the fans were melted.

@RussianOne:Once I was printing PS and left a long print for night, it wasn't tall too. The print got off the table and hotend was pushing hot PS into itself for whole night straight. I woke up to see whole printing head submerged into burnt PS, terrible (probably poisonous) smell. Had to change whole printing head after this

@Fr0st0121: Worst fail I had, put a new hotend on (won't say which one) and was working on my mando helm for a prop, got about 75% done and boom, heat creep which leads to pasta all over the board. Wasted about 100 grams of filament and around 60 hours of print. Spent over a week trying to figure out where I went wrong. It was the hot end.

@Fear Grounds: I FDM printed an entire sailing ship, masts and all. Printing all the parts takes about 10-14 days, only using a single E3 V2. When I got all the pieces put together and assembled, I sat back and enjoyed the beauty of what was created. About two weeks later, I jarred the table holding the ship, and watched it shatter as it sailed right onto the concrete floor.

@Scidude09: Another time, I hadn’t screwed my nozzle in enough and the plastic spewed all over the place that was burnt. Funny thing is when my filament burns it smells like maple syrup and it’s a little good, so you stay until you have a headache. I spent the next four hours cleaning out my hotend and all of the things around it. The nozzle itself got filled up with plastic on its threads and I threw it out

@QuietOne4000: In perspective, my worst printing failures were not exactly unfortunate - they were caused by lack of knowledge or care. For example, after I upgraded my extruder to all-metal Sprite Pro, all my PLA prints started to fail after some hours of printing - very frustrating. Then I learned that it was caused by heat creep - and corrected it.

@Steve 2.3: My problem was I brought a brandnew ender 3 max and everything I printed wouldn't stick to the bed and wrap even with a level bed so I ordered a new glass after trying everything and bomb first print come out flawless, if I set auto home then disable steppers and moved the extruder to the center and moved the bed to the back you could see the glass was wavy, doesn't happen with the new bed

@MaM: I have a new baby cat. I just lunch m’y print, everything is ok. I see the cat going to the kitchen, and i go to the toilet. When i come back, i see my cat playing with my printer.
