Where to find layer height settings in Cura

Layer height in Cura is found in the Print Settings panel on the right side of the screen. Open any model, then look for the Layer Height field under the "Quality" section. The default is usually 0.2 mm. Click the number field and type a new value, or use the up and down arrows to adjust it.

If you don't see the Quality section, your settings panel may be collapsed. Look for a small arrow or plus icon next to "Quality" and click it to expand. If the entire settings panel is hidden, go to the top menu, click View, then make sure Settings is checked.

Key Takeaways

  • Layer height is in the Quality section of the Print Settings panel on the right side of Cura's main window.
  • Lower layer heights (0.1 mm or less) produce finer detail but take longer to print; higher values (0.3 mm or more) print faster but with less detail.
  • Your nozzle size limits how low you can go — a 0.4 mm nozzle should not use layer heights below 0.1 mm.
  • Changing layer height affects print time and material use, so test on a small model first if you are new to adjusting it.

Understanding what layer height does

Layer height controls how thick each printed layer is. A 0.2 mm layer height means Cura will slice your model into layers that are 0.2 millimeters tall. Smaller numbers create more layers, which means more detail but longer print times. Larger numbers create fewer, thicker layers, which prints faster but with rougher surfaces and less fine detail.

The relationship is direct: if you halve the layer height from 0.2 mm to 0.1 mm, your print time roughly doubles. If you increase it to 0.3 mm, print time drops significantly. This is why layer height is one of the first settings people adjust when they want to speed up a print or improve surface quality.

Common layer height values and when to use them

Most 3D printers with a 0.4 mm nozzle work well between 0.1 mm and 0.3 mm. A 0.1 mm layer height gives fine detail and smooth surfaces but takes the longest. Use this for miniatures, models with small text, or anything where surface quality matters more than speed. A 0.2 mm layer height is the standard default — it balances quality and speed for most prints. A 0.3 mm layer height prints noticeably faster and works for larger models, prototypes, or functional parts where surface finish is less critical.

Some printers can handle 0.4 mm or higher, but this depends on your nozzle size and printer calibration. A 0.4 mm nozzle should not go below 0.1 mm, because the layer becomes too thin for the nozzle to deposit material reliably. If you have a 0.6 mm or 0.8 mm nozzle, you can use thicker layers like 0.4 mm or 0.5 mm.

How to change layer height for specific parts of a print

Cura allows you to change layer height for just part of a model using the Per Model Settings feature. Right-click on your model in the 3D view and select Per Model Settings. A new panel appears where you can set layer height to apply only to that model. This is useful if you are printing multiple objects and want one to be high detail while another prints faster.

You can also use Print Profiles to save different layer height settings as presets. Go to File > Save as Profile, give it a name like "Fine Detail" or "Fast Print", and Cura saves your current settings. Next time you want those settings, go to File > Load Profile and select the one you saved. This saves time if you regularly switch between layer heights.

What happens to print time and material when you change layer height

Cura shows estimated print time and material weight at the bottom of the screen. When you change layer height, these numbers update automatically. Lowering layer height increases both time and material use slightly — the extra material goes into the additional layers needed to reach the same height. Raising layer height decreases both.

The time change is not always linear. Reducing layer height from 0.2 mm to 0.1 mm might increase print time by 80 to 100 percent, depending on your printer's speed settings. Cura's estimate accounts for your printer's acceleration and speed limits, so the number shown is usually close to real print time. Always check the estimate before starting a long print with a new layer height.

Troubleshooting layer height problems

If your print has gaps between layers or layers are not sticking together, your layer height may be too low for your nozzle or printer. Try increasing it by 0.05 mm and print a test. If the first layer does not stick to the bed, the issue is usually bed leveling, not layer height — but if only the first layer fails, try raising layer height slightly to give the nozzle more material to work with.

If you see rough surfaces or visible layer lines even at 0.1 mm, the problem is usually not layer height but nozzle temperature, print speed, or bed leveling. Layer height alone cannot fix those issues. If you are unsure whether your layer height is the problem, print a small test cube at your current settings and examine it before printing a large model.

Frequently Asked Questions

Can I use a layer height smaller than 0.1 mm?

Technically yes, but not recommended for most printers. A 0.4 mm nozzle struggles to deposit material reliably below 0.1 mm because the layer is too thin. If you need finer detail, consider a 0.2 mm or 0.3 mm nozzle instead, which can handle 0.05 mm or 0.06 mm layers. Check your printer's manual for the minimum recommended layer height.

Does layer height affect how strong my print is?

Slightly. Thinner layers create more layer-to-layer bonds, which can make prints marginally stronger. However, the difference is small compared to factors like infill density, print speed, and nozzle temperature. If strength is your goal, adjust infill percentage first, not layer height.

What layer height should I use for my first print?

Start with 0.2 mm, which is Cura's default. It works for most models and most printers. Once you see how your printer handles it, you can experiment with 0.1 mm for detail or 0.3 mm for speed. Do not jump to extreme values on your first try.

If I change layer height, do I need to re-slice my model?

No. Cura re-slices automatically whenever you change a setting, including layer height. You will see the preview update and the time estimate change within a few seconds. You do not need to reload the model or do anything else.
