If you set a low layer height, then that also means that more layers will be needed to 3D print a model. This enhances the overall mechanical strength of the part especially against any stress in the X and Y directions. Printing with thicker layers is an excellent way to reduce the number of layer interfaces. This is similar to two solid pieces that have been glued together – if a part fails, it will likely fail at the point where individual pieces are joined. In a 3D printed project, the interface between the layers is considered its mechanical weak point. Even if layer lines can be sanded smooth, changing the geometry of a surface to look curved will take considerably more work in post-processing. ![]() This can be very off-putting for projects that value design quality and appearance. Using thick layers on a curved surface will make it look staggered or broken apart into steps like stairs. However, curved surfaces are a bit more complex as these are merely approximated using straight layers. This is not problematic when it is done to create a model with lots of straight surfaces. The surfaces of a 3D print are created by a series of straight layers laid on top of each other. In this regard, setting a small layer height is very favorable for prints that have lots of fine details. This is akin to the resolution of a video or photo and is one of the factors determining how good small details will look in the finished product. In 3D printing, the layer height is considered the resolution along the Z-axis. When setting a layer height value, these are the possible results that you should consider: Detail resolution There is a wide range of layer height values and choosing one over the others involves coming to a compromise between different quality and performance parameters. ![]() ![]() It is the thickness of each layer that is deposited by the nozzle to build the 3D print based on the sliced model. The term “layer height” is self-explanatory. If you’re planning on experimenting with layer height, then we recommend knowing the ideal settings and understanding how it affects the characteristics of your finished 3D print. Whether you’re after quality or speed, layer height is one of the most important settings in 3D printing. Regardless of your choice, your layer height setting should not exceed 80% of the nozzle diameter to ensure sufficient layer adhesion. However, setting a higher layer height significantly reduces printing time and creates mechanically stronger parts. Using a lower layer height favors better detail accuracy and resolution. 3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways.
