Just wrap a clean piece of sponge attached to a plastic clamp around the filament so that the dirt ends up gets cleaned there before getting into the hotend path. At first I presumed it was an overheating issue so installed heatsinks on steppers and bought a remote temperature device to monitor. So I recently attempted some ASA printing and found the filament to be lacking. Very frustrating. Signup and get our monthly squeeze on updates, blog, printables and much more. Too Much Strain This problem is made worse when youre trying to print something that requires a lot of retractions in a short amount of time. I hope other people find this post and save themselves a lot of anguish and hours of crashed print jobs. So turn off the printer for some time allowing components to cool down. I did all the stuff your supposed to when moving filaments. Next try, same game exactly. Now turn off the heater, and let things cool down to about 50-60C. https://americanfilament.us/blogs/3d-printing-guide/how-to-fix-clogs-and-obstruction-in-a-3d-printer-hot-end. Make sure the z-homing height calibration is performed properly. If the printer is not extruding enough, the extruder may be clogged. If so it's nice and tight. All the Best. This problem arises due to a combination of natural nozzle wear and tear, poor quality filament, too high print temperature, or damage to components like the PTFE tube and extruder. Alternatively, you can do this by inputting G-code to lay down a set number of lines on the edges of the build plate away from where the print will sit before starting the print in earnest. Theres only one long term solution to fixing a worn or damaged PTFE tube, and thats replacement. This article will take you through some useful tips and advice to create good quality 3D printed holes without supports. All flexibles are made from TPE thermoplastic elastomers though there are a number of different types that are best for different types of 3D printing. How Flexible is TPU The front fan cap should be closed all the time when the extruder heaters are active. This technology never ceases to amaze me, and I always thrive to stay up to date with the newest trends in the space. Too high infill parameter. This solution may fix your issue, but it wont guarantee that all residue got extruded out of the nozzle. The good news is that more and more 3D printer manufacturers are including this feature by default. We have more guides here: Tom Bardwell is a contributor and the newest face here at 3DSourced.com. It typically prints at between 210-250C, sticks well to painters tape as a great build surface to use, and works well with a heated bed of up to 60C. If your extruder stops depositing filament on the successive layers, it is almost definitely not caused by this. Then I would take the nozzle off and push out the plastic from the hot end. Below are some other techniques to fix a clogged nozzle. Try to reduce the amount of retractions or set your retracts to be less aggressive. E3D-v6 hotends need less retraction than most hotends. Deformed Filament Remove the filament from the extruder and check how it looks. A poor quality filament and involuntary contaminants lurking inside the material can accumulate and clog directly inside the nozzle at random intervals.
