Introduction

In this article, we will explore how to take our 3D prints to the next level by using a setting called ironing in Cura. Ironing is a technique that allows for the creation of smooth top layers on our prints, giving them a more finished and professional look. We will discuss what ironing is, how to adjust the Cura settings for ironing, different types of ironing patterns, and various parameters to consider for optimal results. Additionally, we will provide tips for achieving smooth ironing and compare prints with and without ironing to showcase the difference it can make.

1. What is Ironing in Cura?

Ironing is a setting in Cura that allows for the application of a skim coat on top layers of a 3D print. After the normal layer lines are laid down, Cura will come back and add a small amount of plastic while the nozzle moves back and forth. This creates an ironing surface that smoothly wipes and adds filament to create a polished, smooth top layer. By implementing ironing, we can significantly improve the appearance of our prints.

2. Adjusting Cura Settings for Ironing

To enable ironing in Cura, we need to adjust the settings in the software. First, switch to the expert setting in Cura. Then, select the desired layer Height and number of walls for the print. Next, navigate to the ironing section and enable ironing by clicking on 'Yes.' We can choose to iron only the highest layer or iron all the flat surfaces. The ironing pattern can be set to zigzag, concentric, or a custom pattern of choice. Additionally, we need to adjust the ironing line spacing, which determines how far the nozzle will overlap on each pass. Flow should be set to ensure proper filament extrusion, typically ranging from 10% to 15%. Finally, the ironing inset should be adjusted to control the distance from the edge at which ironing occurs.

3. Types of Ironing Patterns

Cura offers different types of ironing patterns: zigzag, concentric, and custom. The zigzag pattern creates a line that wipes back and forth, covering the entire print surface. The concentric pattern starts at the outer perimeter and works its way towards the center in a circular motion. Custom patterns can also be created Based on individual preferences. Each pattern has its own visual effect on the print, and selecting the most suitable one depends on personal preference and the desired outcome.

4. Setting the Ironing Line Spacing

The ironing line spacing determines how far the nozzle will overlap on each pass during ironing. It is advisable to set the spacing to approximately half the diameter of the nozzle to ensure proper coverage. For example, if using a 0.4mm nozzle, a spacing of 0.2mm would be appropriate. Experimentation may be required to find the ideal spacing for different printers and filament types.

5. Controlling the Filament Flow

Maintaining proper filament flow is crucial for successful ironing. It is recommended to set the flow between 10% and 15%. This ensures a constant flow of filament from the extruder, preventing clogs and inconsistencies in the ironing process. Adjusting the flow rate within this range may be necessary depending on specific printer characteristics and filament properties.

6. Choosing the Ironing Inset

The ironing inset refers to the distance from the edge at which ironing will occur. It is important to set a positive value to avoid leaving a lip or edge on the print's surface. By skimming the nozzle just slightly inside the edge, a clean and smooth surface can be achieved. Experimentation with different inset values may be necessary to find the perfect balance for each print.

7. Tips for Achieving Smooth Ironing

To ensure smooth ironing, it is essential to have a well-calibrated and properly tuned 3D printer. Any mechanical issues or movement during printing can result in inconsistent ironing. Additionally, the nozzle must be sitting at a perfect 90-degree angle to the bed surface. If the nozzle is tilted, the top layer will appear staggered, resembling roof shingles instead of a smooth surface. Taking the time to adjust the printer and nozzle position will greatly enhance the ironing results.

8. Comparison: Prints with and without Ironing

By comparing prints with and without ironing, the impact of this technique becomes evident. The print without ironing often shows visible layer lines, highlighting the individual passes of filament laid down by the nozzle. On the other HAND, the print with ironing exhibits a smooth and polished top layer that resembles the bottom of the print. The difference in aesthetics is significant, and ironing can lend a more refined look to 3D prints.

9. Conclusion

In conclusion, implementing the ironing setting in Cura can significantly enhance the appearance of our 3D prints. By applying a skim coat to the top layers, we can achieve a smooth and polished finish. Adjusting the settings correctly and ensuring proper printer calibration are essential steps to achieve the desired results. With ironing, we can take our prints to the next level and give them a more professional and refined look.

Highlights

• Ironing is a setting in Cura that adds a skim coat to the top layers of 3D prints for a smooth finish.
• Adjusting Cura settings, such as layer height, wall count, ironing pattern, line spacing, flow, and inset, is crucial for optimal ironing results.
• Different ironing patterns, including zigzag and concentric, offer distinct visual effects on the print surface.
• Proper calibration and alignment of the printer are necessary to achieve smooth ironing.
• Prints with ironing exhibit a polished top layer, while prints without ironing Show visible layer lines.

FAQ

Q: Can ironing be used on all types of 3D prints?
A: Yes, ironing can be utilized on most 3D prints that have top layers, regardless of their complexity or design.

Q: Does ironing affect the structural integrity of the print?
A: Ironing primarily affects the surface finish of the print and does not have a significant impact on the overall structural integrity.

Q: Can ironing be applied to prints with multiple materials or colors?
A: Ironing can be applied to prints with multiple materials or colors, but each material or color may require separate adjustment of the ironing settings.

Q: Can ironing be used with all types of filaments?
A: Ironing is compatible with most commonly used filaments, such as PLA, ABS, PETG, and others. However, it is advisable to experiment and adjust the settings according to the specific filament properties.

Q: Does ironing increase print time?
A: Yes, enabling ironing will increase the print time as it adds an additional step of smoothing the top layers. The extent of the time increase depends on the size and complexity of the print.
