If 3D prints cool unevenly, they can curl away from the build plate. Check out 3 easy ways to fix 3D print warping (PLA, PETG & ABS).<\/p>\n<\/div>\n<\/div>\n

Whenever some part of your printing object starts to curl upwards, you\u2019ve got a warped 3D print on your hands. The problem occurs because the temperature differences between layers of extruded plastic are too big. This, in turn, creates tension within the model, and when it gets to be too much, lower layers start to drag or lift, creating a warp.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Why Does It Occur?<\/h3>\n<\/div>\n

Filaments used in\u00a0FDM 3D printing<\/a>\u00a0are usually thermoplastics, materials that can melt (turning to liquid), cool (turning to solid), and still keep their mechanical properties. In 3D printing, we heat the filament to somewhere beyond its melting point so that, in its liquid form, it can be extruded onto a build plate.<\/p>\n

While heating, thermoplastics expand, shrinking again when they cool down and return to a solid. This transformation creates some movement in extruded plastics, which is the root of 3D print warping: colder layers pulling on hotter layers as they contract. And if this occurs when the hotter layers are below the colder ones, the 3D printed object will be forced to let go of its grip on the build surface, and curl upwards.<\/p>\n

To make matters worse, the problem can (literally) pop up after a good portion of the print job is already finished, ruining an otherwise perfect print!<\/p>\n

If we could keep the whole 3D printed model at the exact same temperature at all times, not even a tiny corner of the model would try to warp. But this is pretty much impossible. What we can do is try to keep the 3D printed model\u2019s temperature as even as possible. And we can also do our best to convince the model to\u00a0hold on to the build surface<\/a>\u00a0like its life depends on it!<\/p>\n

Below, we\u2019ve covered three methods to attempt to combat warping and save your prints.<\/p>\n<\/div>\n

Rare Case: Print Bed Warping<\/h3>\n

Some hobbyists have reported the print bed warping along with the print, and this seems to mostly occur with large prints (with broad first layers) on spring steel surfaces. This likely occurs because the large print accumulates even more warping forces than usual and the flexible build plate \u2013 though sticking well to the print \u2013 bends along with it! If you experience this problem (or are worried you might) and aren\u2019t able to apply the following solutions to mitigate it, consider switching to a\u00a0glass build plate<\/a>.<\/p>\n<\/div>\n

Temperature, not just of the filament but of the bed and the surrounding air, is perhaps the most important factor in preventing warping. Here are some tips on maintaining the optimal temperature conditions:<\/p>\n
