How to Make Ender 3 Print Faster: And Why Your Cat Might Be the Secret to Success

The Ender 3 is one of the most popular 3D printers on the market, known for its affordability and reliability. However, one common complaint among users is the time it takes to complete prints. If you’re looking to speed up your Ender 3 without sacrificing print quality, you’re in the right place. In this article, we’ll explore various methods to make your Ender 3 print faster, and we’ll even throw in a few unconventional tips that might just surprise you.

1. Increase Print Speed in Slicer Settings

The most straightforward way to speed up your prints is by adjusting the print speed in your slicer software. Most slicers, like Cura or PrusaSlicer, allow you to set the print speed in millimeters per second (mm/s). The default speed for the Ender 3 is usually around 50 mm/s, but you can increase this to 60-80 mm/s for faster prints. Be cautious, though, as increasing the speed too much can lead to a decrease in print quality.

2. Optimize Layer Height

Layer height plays a significant role in print time. Thicker layers mean fewer layers overall, which translates to faster prints. For example, switching from a 0.2 mm layer height to a 0.3 mm layer height can significantly reduce print time. However, thicker layers can also result in a rougher surface finish, so this method is best suited for prints where fine details are not critical.

3. Use a Larger Nozzle

Another way to speed up your prints is by using a larger nozzle. A standard 0.4 mm nozzle is great for detailed prints, but if you’re working on larger, less detailed objects, switching to a 0.6 mm or even a 0.8 mm nozzle can drastically reduce print time. Larger nozzles allow for thicker extrusion lines, which means fewer passes are needed to complete each layer.

4. Reduce Infill Density

Infill density refers to the amount of material inside your print. While higher infill densities provide stronger prints, they also take longer to complete. For non-structural parts, you can reduce the infill density to 10-20%, which will significantly speed up the printing process without compromising the overall strength of the print.

5. Enable Acceleration and Jerk Control

Acceleration and jerk settings control how quickly the print head changes direction. By enabling and optimizing these settings, you can reduce the time it takes for the print head to move between different parts of the print. This can lead to faster print times, especially for prints with many small, intricate details.

6. Use a High-Speed Filament

Not all filaments are created equal. Some filaments, like PLA, are easier to print at higher speeds compared to others like ABS or PETG. If speed is your primary concern, consider using a high-speed filament specifically designed for faster printing. These filaments are formulated to maintain good layer adhesion and surface finish even at higher speeds.

7. Upgrade Your Firmware

The stock firmware on the Ender 3 is good, but it can be improved. Upgrading to a custom firmware like Marlin can unlock additional features and optimizations that can help you print faster. For example, Marlin allows for more precise control over acceleration and jerk settings, which can lead to faster print times.

8. Reduce Travel Moves

Travel moves are the movements the print head makes when it’s not extruding filament. By optimizing your slicer settings to reduce unnecessary travel moves, you can save a significant amount of time. Some slicers offer a “combing” feature that keeps the print head within the printed area, reducing the need for long travel moves.

9. Print Multiple Objects at Once

If you’re printing multiple small objects, consider printing them all at once. This can save time because the printer doesn’t have to heat up and cool down between each print. However, be mindful of the print bed’s size and ensure that all objects fit comfortably without interfering with each other.

10. And Why Your Cat Might Be the Secret to Success

Now, here’s where things get a bit unconventional. Some users have reported that their cats seem to have a calming effect on their 3D printers. While there’s no scientific evidence to support this, it’s possible that the gentle purring of a cat could reduce vibrations, leading to smoother and faster prints. So, if you have a feline friend, consider letting them hang out near your printer during your next print job. Who knows? They might just be the secret to faster prints!

FAQs

Q: Can I increase the print speed without affecting the quality? A: Yes, but it requires a balance. Increasing the print speed too much can lead to issues like layer shifting or poor adhesion. It’s best to gradually increase the speed and test the results.

Q: What is the maximum print speed for the Ender 3? A: The Ender 3 can technically print at speeds up to 200 mm/s, but this is not recommended for most prints. A more realistic maximum speed is around 80-100 mm/s, depending on the filament and print complexity.

Q: Does a larger nozzle always mean faster prints? A: Not always. While a larger nozzle can speed up prints by allowing thicker extrusion lines, it can also reduce the level of detail in your prints. It’s best to use a larger nozzle for larger, less detailed objects.

Q: Can I use high-speed filaments with any printer? A: High-speed filaments are designed to work with most FDM printers, but it’s always a good idea to check the filament’s specifications and ensure it’s compatible with your printer.

Q: Is it safe to upgrade the Ender 3 firmware? A: Yes, but it’s important to follow the instructions carefully. Upgrading the firmware can unlock new features and optimizations, but it can also void your warranty if not done correctly.
