Hi, I’m still new to 3D printing and I could use some of your expertise please. I’m using a Flashforge Creator Pro and Simplify 3D software. I’m having a problem where it looks like either the filament is bubbling up or not quite covering the infill. It seems to be a little better toward the right side of the print but I can’t see how leveling would create these bumps. I’m using 4 solid top layers and 2 outline/perimeter shells and primary layer height 0.1 mm. Thanks for your help.
Also…this is ABS. On the other side between the rafting (which I have to use for anything to print on both ABS and PLA for some reason) and the 1st layer, I’m getting these separated striations and stringing from open cavities. I’ve tried lowering the global g-code offset for the z-axis to -0.05 mm and the first layer height is 90%, width 100% by default. The better side is just the opposite from the top and looked better with less separation where it was laying on the left (right when you flip it up), while the top layer looked better on the right. Any ideas what could cause this?
My analysis of the photos is uneven extrusion.
Temperature too low or
Printing too fast or
Filament diameter.
Measure your filament is step one.
Ok. I’m printing at 250 on the extruder and 115 on the bed. Speed is 3600 mm/min. I have digital calipers that I measured the filament with and the measurements do vary between 1.7-1.83. It’s the filament that came with the printer so may not be high quality. Thanks for your help!
Hi Wendy, I’m relatively new to 3d printing as well and have a FlashForge Creator Pro using the ReplicatorG software that came with. I’m having a similar problem on my top layer, except that it is when I use PLA that I have the problem. ABS seems to print fine (minus occasional warping), but the top layer of PLA has bubbles that look almost exactly like what you show in your pictures. Did you ever figure out a solution to your problem? Maybe I can try something similar to what you did to fix it.
I’m printing at 200C and 90mm/s. I haven’t tried slowing the speed down yet, but I’ve played with the temperature a little and it doesn’t seem to make a difference.
Thanks for the help!
Adam
