If you’re reading this, you’re probably trying to eliminate or hide layer lines in 3D prints. However, layer lines are only a problem until you see them as such. They are neither good nor bad; they are simply a byproduct of the additive process. Consider layer lines as a trade-off for the numerous benefits of 3D printing.

However, we agree that these are not always desirable and can even be ugly at times. So, while layer lines can be reduced, they cannot be completely eliminated. Certainly not during the printing process. You can always use post-production techniques to accomplish this. But did you know that you can hide layer lines in 3D prints.

Yes, you we can use a variety of tips and tricks to hide layer lines in 3D prints so that they are not visible. We’ll share these tips with you below, so make sure to read all the way to the end.

What are Layer Lines?

Before we get into the tips and tricks, let’s go over what layer lines are. Layer lines are visible ridges or lines on the surface of a 3D printed object using fused deposition modelling (FDM) 3D printers. These lines are formed by depositing successive layers of filament on top of each other to form the final object.

Each layer of melted filament is deposited in a specific pattern, typically a zigzag or a straight line, and as a result, the lines are visible on the print’s surface. Several factors can influence the appearance of the layer lines, including printing speed, extruder temperature, layer height, and filament type.

Layer lines are an inherent feature of FDM 3D printing, and while they cannot be completely eliminated, they can be significantly reduced by adjusting printer settings. We have a dedicated article on reducing layer lines in 3D prints that you will find useful.

Tips and Tricks to Hide Layer Lines in 3D Prints

Make use of Textures

Unlike traditional processes, 3D printing has the ability to print complete parts that do not require any additional processing. As a result, 3D printing a part with a textured surface is very much possible and can be incorporated into the design for free.

Textures are an inherent part of the product in some parts, such as a grip, handle, etc., but you can also use these textures for hiding the layer lines in 3D prints. Textures can also improve the aesthetics of a part, as well as its strength and function, which is an added benefit.

You can make your own 3D textures using software such as Solidworks, SelfCAD, Blender, ZBrush, and others. Surface textures can also be created using the IdeaMaker Slicing software. Check out this video to know more.

Make better Material Choice

If you do not want to use the texture method, you can certainly make a better material selection decision. Layer lines are visible because the parts are typically printed in a single colour, making it easier to spot the layer lines.

As a solution, consider using blended materials such as marble-fill, wood-fill, metal-fill, ceramic, hemp-based materials, and so on. This breaks up the monotony of the part surface while also concealing the layer lines. The layer lines blend in with the design and are practically invisible.

Make use of Layer Lines

Yes, you read that correctly. That is, as a designer, you must use layer lines to your advantage and make them an integral part of the design. Instead of attempting to eliminate the lines, incorporate them into your design so that they add to the aesthetics of the 3D printed part.

While this method is not appropriate for all parts, it is certainly feasible for artistic and creative models.

Spiral Vase Mode

Another way to hide layer lines is to use a slicer setting called spiral or vase mode, which is available in most slicer software programmes. In this mode, the nozzle prints the object’s outer contour continuously like a single layer.

The transition to the next layer is smooth, giving the movement the appearance of a spiral. This method, unlike traditional printing, produces a smooth surface rather than a seam along the Z-axis.

There are some limitations to using this mode. You have to ensure that the model does not have any holes in its shell, the model is printable without support and the model need not be strong (since the model will only have one wall the object is not printed for strength, rather just for design communication).

The benefits include a reduction in horizontal layer lines and spiral lines that appear to be a deliberate aesthetic choice to make the object more appealing. Objects are printed more quickly and with less material.


It’s not always easy to reduce layer lines, so the easier option is to try to hide layer lines in 3D prints so you don’t have to go to the trouble of removing them through post-processing. These tips and tricks will undoubtedly assist you in achieving better results. While it is not a replacement for every print, it is an option to consider when using these tips on your 3D prints.
