I am brand new to 3D printing and purchased an X1 Carbon. I’m using Bambu filament, PLA and PETG.
I’ve had a couple of successful test prints with PLA and one with PETG (on the engineering plate.) On a larger print last night with PETG I noticed that some spiderwebby material lifted off the plate and then got caught in the nozzle. After that the material progressively globed up on the nozzle into a large clump. I stopped the print and cleaned it off. I tired a second print and it did the same thing.
This morning I’m trying a different print and it seems to be working as I type this but there is tons of debris coming off the print onto the plate as you can see in the photo. I’ve also noticed that as the print builds there is artifact material and spiderwebby stuff on the layer being built. Is this typical?
I would appreciate any and all advice - please understand that I am brand new at this. Thank you in advance.
I’ve only had my X1C for about three weeks but this is my 3rd 3D printer so I’m not a newbie. Anyway I’ve printed with ASA, PC, PETG, PLA, etc on various plates and I’ve never had that problem of yours. My prints are with Bambu filament using stock settings for slicing and printing. Did you do the usual calibrate and bed leveling, etc?
It’s significantly easier to remove parts from the PEI plate and it works with a variety of filaments, the texture on the bottom layer might be attractive or not. Personally I like it for most builds.
My only printing struggle is with TPU (MatterHackers), I’m not getting consistent results so I’m going to try Bambu TPU.
. . . and now that I’m trying to print a large flat object, think small iPad sized case things go great until about 3/4 of the way through the first layer. And it’s always in the same area on the same side.
I tried Bambu PLA, and PETG, I’ve tried the cool plate with PLA, and the engineering plate with the PETG with glue stick and with the liquid stuff. I’ve tried the textured PEI plate without and with glue. I’ve cleaned the plates after every use and don’t touch them afterward. I’ve tried slowing down the speeds and kicking up the temperature of the nozzle five and ten degrees from the programmed settings. THe same thing keeps happening. Nothing has worked so far.
This is the last print. you can see how nicely it lays down for more than half ot it. But then it all goes to hell.
I did notice one thing … when the hot end went to the far back corner a couple times I noticed the light reflection on the plate seemed to jiggle just a tiny bit, like something bumped the heating bed. I wonder if there is some issue there which causes disruption of the filament and a snowballing gunking issue.
The “giggling” you are seeing is probably the active bed leveling working.
Did you run the bed leveling (the check box when you sent the print) at the start of the print? Another things to watch out for is if there is anything stuck to between the bed and the build plate that would throw the level off?
Did you wash the bed with dish soap and hot water? I remember you saying something about it being new but you should still wash it. It’s very important to not touch the build surface.
Yes, I have done that for each print. I can’t see anything stuck.
Yep! Each time with Dawn and hot water. Then I’ve used glue stick, liquid glue (Bamu) and no glue on the textured PEI. I’ve tried it all. I’m very careful to only hold the plate by the edges and have held it with a paper towel as I manipulate it into the printer.
I’m using the programmed profile in the printer for Bambu PETG. It’s doing a print right now and is at 75C.
I decided to try to print the iPad-like case vertically because I need it as a prototype to keep moving forward with my project. I understand that the support structure is going to be a pain to remove but it’s okay, it doesn’t have to be perfect.
Wow, looks more like CNC machining. I never had any problems with Bambu PETG and standard profiles (and lid open for massive parts) but I think I did run it in the dryer before I even tried. So like Jon said that is probably your best bet.
NO! But I ordered a single spool drier and will try that next. We’re in Ft. Lauderdale, Florida which is generally pretty humid though a front came through a couple of days ago and it’s very dry.
I’d like the new Sunlu S4 but apparently they are all sold out in the U.S.
I changed out the .04 for a new .06 and this morning I did a large print. It came out perfectly with no debris or any issues.
Since I made two changes (hot end and dry filament) I’m not sure which did the trick. Moving forward I’ll watch closely for changes and try to determine what’s causing issues.
