A Guide to Cura’s Key Settings for Quality and Efficiency
Quality 3D printing often requires optimizing several key printing parameters in Cura. While there are hundreds of custom settings available, only a handful make a significant impact on the efficiency and quality of your 3D prints. By adjusting a few critical settings, you can achieve faster print times without sacrificing the strength and accuracy of your models.
In this guide, we will cover the most influential Cura settings and how to configure them for the best results. Whether you’re new to slicing or looking to take your prints to the next level, you’ll learn how to balance speed and quality through proper slicer settings. Let’s dive in!

Layer Height
Layer height determines the thickness of each deposited layer of plastic. For a finer resolution and smoother surface finish, use thinner layers around 0.1mm or 0.15mm. However, this comes at the cost of longer print times.
If you need quicker, rougher draft prints, a layer height of 0.2mm to 0.3mm will provide a good balance while still retaining accurate details and strength in most models. One notable exception is the first layer — keep this set higher at 0.3mm for improved bed adhesion.
Suggested Settings:
- Regular Prints
- Layer Height: 0.2mm
- High Quality Prints
- Layer Height: 0.1mm
- First Layer Only
- Initial Layer Height: 0.3mm
Line Width
Your extruder has a specific nozzle diameter, so the line width should match this size — typically 0.4mm. If set too low, your extruder may struggle and clog. A greater line width can eliminate gaps but goes through more filament. 0.45mm is often the highest reasonable setting before excess material usage.
Suggested Setting:
- Line Width: 0.4mm (nozzle diameter)
Wall Thickness
Ultimaker Cura’s detailed layer view showcasing a 3D model’s wall thickness and infill density customization.
Increasing wall thickness makes prints stronger and less likely to crack, especially with large flat surface areas. However, excess thickness also uses more material unnecessarily. Stay under 2mm, with 1.2mm-1.6mm being ideal for the external shell on regular sized prints. Too thin and tall models risk collapsing under their weight while printing.
Suggested Settings:
- Wall Thickness: 1.2mm-1.6mm
Top/Bottom Thickness
Ultimaker Cura interface with a focus on top and bottom layer thickness settings for a 3D printed model.
The top and bottom skin layers impact strength and print times. 4–6 top layers are standard, with just 1 or 2 extra layers needed for a smoother bottom surface. Keep these reasonably thick around 0.8mm (4 x 0.2mm layers) on the bottom and 0.6mm-1mm on top. Beyond 8 layers gives little extra benefit for the time cost.
Suggested Settings:
- Top Thickness: 6 layers (approx 1mm)
- Bottom Thickness: 4 layers (approx 0.8mm)
Infill Density
Fine-tuning 3D print durability with Ultimaker Cura’s infill density and pattern settings.
Infill refers to the interior structure that forms the inside of your print. A lower infill percentage produces a lighter, weaker model more quickly. For better density and strength, use 40–60% infill on functional parts or parts needing reinforcement. Generally 20% infill is suitable for non-critical items. Higher values up to 100% are very dense but print quite slowly — use sparingly if needed only in specific areas.
Suggested Settings:
- Decorative Prints: 10–20%
- Functional Prints: 40–60%
Infill Pattern
Adjusting print strategies with Ultimaker Cura’s comprehensive layer view for optimal infill and quality.
Along with infill density is the internal pattern itself. The grid, zigzag, triangle or cubic options offer a decent balance of strength and print time. Line patterns yield a quicker print but weaker part, while concentric can enhance vertical strength but takes longer. Solid infill is naturally the firmest but substantially increases material and print duration. Pick patterns appropriately based on the required strength and geometry of that area of the print.
Suggested Settings:
- Regular Prints: Grid, Zigzag, Triangle
- Vertical Strength: Concentric
- Maximum Strength: Solid
Infill/Perimeter Overlap
Controlling where infill bonds with the outer walls adjusts strength and print times. An overlap of 10–15% keeps prints structurally sound without excess material or time costs. If adhesion is poor between infill and perimeters, increase to 25%. Higher values up to 60% add resilience but shouldn’t be needed for general prints.
Suggested Setting:
- Overlap Percentage: 10–15%
Fine tuning the settings above offers noticeable gains in speed while retaining high quality results from your prints. Be sure to check our in-depth guides on each topic for further configuration tips as you advance your slicing skills. With the right Cura settings dialed in, you’ll achieve better prints in less time.
