Why is Resolution important in 3D printing

3d printing

Add Resolution of 3D printing affects the amount of detail


The two planar 2D dimensions (X and Y) and the Z dimension makes it 3D printing to be taken into account. It is a completely distinct method that handles the resolutions of the planar and Z dimensions and so, they are often governed by completely distinct methods. As a result, there is much misunderstanding about the revolution of 3D printing and the expected degree of print quality.

What distinguishes a high-resolution 3D printer? There isn’t a single, precise solution. You must take into account at least two values since 3D printers generate components in three dimensions: the minimum feature size of the XY plane and the Z-axis resolution (layer thickness or layer height). Even though the Z-axis resolution has less to do with the print quality and surface polish, it is nonetheless frequently reported since it is simple to calculate. Since microscopic imaging is used to test the more significant XY resolution (minimum feature size), it is not often included on spec sheets.

In real terms, it means you should choose a 3D printer that excels in both areas (in all 3 dimensions).

Acknowledging the XY Resolution of 3D printing

Nothing affects print quality more than XY resolution in the realm of 3D printing. Often debated but hardly ever acknowledged, the notion of XY resolution (sometimes called horizontal resolution) differs by 3D printing technology:

  • The combination of the laser’s spot size and the increments by which the laser beam may be modified is used in SLA and LFS 3D printers.

  • The smallest feature that a DLP 3D printer can replicate in a single layer is the pixel size.

  • The smallest movement the extruder is capable of making inside a single layer on FDM 3D printers.


As a general rule, the more specifics, the lower the number. However, even when it is, the stated amount is not necessarily true because this figure is not usually mentioned in spec sheets. It’s crucial to comprehend the mathematics underlying the number in order to accurately determine a printer’s XY resolution.

Z Resolution of 3D printing: An Understanding


One statistic will stand out more than any other on 3D printer spec sheets: Z resolution. The vertical resolution, sometimes referred to as layer thickness or layer height, was the first significant numerical distinction between early 3D printers.

Early machines had trouble breaking the 1 mm barrier, but today’s FDM 3D printers can produce layers as thin as 0.1 mm, and LFS and SLA 3D printers are even more accurate.


We anticipate that choosing a 3D printing service provider that best suits your workflow and output requirements will be considerably simpler now with Crenodez because you are aware of the resolution limitations of 3D printing and how different technologies produce different results.
