The most common causes of layer shifting are: It can occur in the X-axis, the Y-axis or even both simultaneously. Layer shifting is a problem that occurs in the form of a displacement on some axis at a certain height. In general, avoiding draughts (and the consequent temperature variations) and covering our printer will help, but we must be careful to avoid the problems mentioned. This can result in some problems, since an excessive temperature can lead to failures in the electronics: missing steps or losing printing artifacts… it can also cause clogging, since there is not enough difference in temperature between the cold zone and the hot zone of the hotend. The optimal solution would be to cover our printer, as indicated in the previous point. On the other hand, if our problem is thermal contraction the solution is more complicated, as we must manage to create a warmer environment in our printing area. Some materials, like ABS, will always be prone to cracking and will be more difficult to control others like PLA are very easy to print without cracking. To check if our part is cracking due to lack of adhesion between the layers, we can try to raise the temperature and/or reduce the speed of the layer fan, as excessive cooling can also affect it negatively. Printing materials such as ABS at less than the proper temperature often leads to cracking when trying to bond two layers without applying enough heat. Conversely, higher values will give us better layer adhesion. Within this range, lower values will give us a better aesthetic appearance, since the deposition will be “cleaner”. Most filaments have a temperature range in which they can be printed. If the problem is lack of adhesion, it is usually due to low of temperature.

Here’s an article that we made explaining this problem more in depth: How to avoid warping and cracking in my 3D prints.įollowing on from the above problem is cracking or delamination. The idea in this case is to enclose the heat generated by the bed, so that there is not much difference between the temperature of the first layers and the temperature of the upper layers, which are farther away from the heat of the bed.

A large box can work, as well as a more professional enclosure made in a closet. To solve this problem we can simply cover the printer with whatever we have at home. If your problem is related to thermal contraction, increasing the adhesion will not help you too much since, as we have said, the ABS when deformed can even break our printing base. If we are using ABS we can apply a layer of the mixture known as ABS slurry which we can make ourselves by dissolving ABS in a container with acetone. Some known adhesives are the famous Nelly hairspray, or its more professional version 3Dlac. If we are using a glass base, it is highly recommended to use some adhesive to increase the fixation of the part. This happens mostly with materials such as ABS or Nylon, and it is very difficult for it to happen when printing PLA.ĭepending on our problem we can look for a solution accordingly:įor the lack of adhesion there are several solutions. If this occurs, the print surface may even break if it is a BuildTak type, as the sticker will be torn off the bed.

Lack of adhesion to the bed: this can occur due to incorrect height of the nozzle in relation to the base, or poor leveling but also lack of adhesion to the printing surface.In any case, warping can be caused by the following factors: Warping is a decreasingly common problem, as the vast majority of modern printers have hot beds. ❌ Warping, the first layer peels off and the parts bend
