Experienced 3D printing professionals are pretty much experts in troubleshooting, if only because there are so many things that can go wrong in 3D printing . Often, there isn’t even a single solution to solve these problems. The problem-solving process involves a lot of small tweaks and adjustments, and it’s best if you actually understand what you’re doing. A common problem in 3D printing is under-extrusion. It’s pretty easy to spot prints that suffered due to under-extrusion: missing layers, random dots or holes, or very thin layers. Not only do these prints look very bad, but they are also structurally weak. What causes under-extrusion? What settings need to be adjusted to address this problem? What is under-extrusion?
