Print Fail with gaps



  • I'm printing with a Flashforge Creator Pro using ABS with 130c nozzle and 110c bed temp. My print seems to be leaving gaps.The filament is new so I don't think it is a moisture issue.2_1624477417877_Mother-n-Child_3.jpg 1_1624477417876_Mother-n-Child_2.jpg 0_1624477417874_Mother-n-Child_1.jpg



  • 130c? I print abs at 250-260



  • @mpirringer Sorry, I meant 230c, the spool of filament suggests 220-235c

    @ruiser what is your chamber temperature? Never follow what the filament suggests, I always find this temperature way too low. Mpirringer is corrrect, try printing at 250C to start and go from there.



  • @tinken I agree on the temperature

    Here is an ABS print done on an Anycubic Chiron the shield is about 300 mm in diameter the multicolor was achieved by inserting an m25 at the appropriate layers and changing filament. The point is that even with a .8 nozzle and a cheap printer you can get decent looking abs prints when you get the settings right. This one was printed at 260C nozzle with a volcano all metal clone and the bed (ultrabase) at 105 and a sheet of plastic draped over it to raise ambient layer height .2-.32 adaptive. Slicer Prusa Slicer. Governed with a max Volumetric E at 24 mm3/sec. We make those for our bigger sponsors to hang on the wall.



  • 0_1624716298757_Mother-n-Child_4.jpg This is the result after setting the nozzle to 250C. I didn't see much improvement.



  • My Flashforge does have an enclosure.



  • @ruiser Try drying the filament I run most anything (except HIPS and PLA) from a print dry (converted food dehydrator) also what slicer are you using, Nozzle size and print settings. you should be able to export the settings from the printer direct or the end of a print gcode file
