To print small-scale parts, curved parts, or parts with a high level of detail, it is generally better to use a low layer height. A low layer height results in better Z-axis resolution, which is particularly important on curved objects: thick layers are more visible and produce a “stepped” effect rather than a natural curve. How layer height affects print qualityĪdjusting a 3D printer’s layer height is one way to ensure high quality. the speed at which the printhead moves along the X and Y axes, but in practice we might say that higher layer heights lead to “faster” printing due to the reduced total print time. Layer height does not technically affect print speed, i.e. However, if the layer height is set to 0.4 mm, then the cube will only have 250 layers in total, and the printer will only have to print 250 squares, taking approximately ¼ of the time. This means that the printer must print 1,000 two-dimensional squares on top of one another. If a 3D model of a cube measures 100 mm in height and is printed with a layer height of 0.1 mm, then it will consist of 1,000 layers in total. We can demonstrate the connection between layer height and printing time with an example. A lower layer height requires a greater total number of layers, and a print with more layers takes longer to print.
The layer height of a print has a direct effect on the total print time. How layer height affects speed and printing time Layer height is a user-controlled parameter that can be adjusted using 3D printer software, but the minimum and maximum layer height is limited by physical aspects of the printer, such as the nozzle diameter and the stepper motors that move the printhead up the Z-axis in fixed increments. Given in millimeters or microns, it shows the resolution of the part along its Z-axis: thinner layers allow for more detail. But what makes a 3D printer unique is its ability to print additional 2D layers on top of the first, building up a part in this layer-by-layer fashion until it is finished.ģD printing layer height - sometimes known as layer thickness, layer resolution, or Z-axis resolution - is a measure of the thickness of each extruded layer of material. That is, the printer squeezes out material in a 2D pattern on the X-Y plane (just like an inkjet printer does on a sheet of paper). To understand layer height, it is important to understand that the majority of 3D printers only use two dimensions when they deposit material. For newcomers, however, it can be difficult to visualize how a part gets built in layers and how these layers can vary in size. “Layer height” is a term used a lot in FDM 3D printing. Layer heightsģD printers can use a low (left) or high (right) layer height What are layer height, layer thickness, and layer resolution? This article examines those reasons while taking a closer look at layer heights, nozzle diameters, and more.
4 nozzle diameter might be your go-to configuration when it comes to FDM printing, there are many reasons why you might want to switch up both parameters. Although the two can be adjusted independently, layer height is partly determined by the size of nozzle fitted to the printer, and it can be helpful to consider both parameters at once.
The relationship between layer height and nozzle diameter is important too. But doing so can open up new printing possibilities: small nozzles can produce much finer details on the X-Y plane, while big ones enable faster printing speeds. 4 mm nozzle as standard, and because this kind of nozzle will suffice for most print jobs, many users never consider swapping out their standard nozzle for one with a narrower or wider diameter. Because most printers are equipped with a. In simple terms, thin layers produce better Z-axis resolution, while thick layers reduce total printing time.Ī printing parameter less talked about is nozzle diameter. When printing parts on an FDM 3D printer, adjusting the layer height is one of the easiest ways to strike a balance between print quality and print time.
