How To Succeed When 3D Printing With PLA Filament // How To 3D Print Tutorial

Summary

This video tutorial provides essential tips for successfully 3D printing with PLA, a user-friendly material favored for its vibrant colors and ease of use. Key advice includes properly leveling the printer bed, adjusting nozzle height for optimal adhesion, calibrating print temperatures, and maintaining clean extruder gears. The tutorial emphasizes the importance of preparation, such as using blue painter's tape for adhesion and managing filament changes to avoid clogs. With clear instructions and practical insights, viewers can enhance their PLA printing experience and achieve high-quality results.

Takeaways

• 😀 PLA is an easy-to-print material that suits both beginners and experienced users.
• 🛠️ Proper bed leveling is crucial for successful prints; adjust using the screws until there is slight resistance with a piece of paper.
• 📏 Pay attention to the nozzle height during the initial print; the skirt should have lines that are slightly squished together.
• 🎨 PLA comes in various colors and can be printed without a heated bed, using blue painter's tape for adhesion.
• 🔥 For heated beds, set the temperature around 70°C for optimal adhesion, or use glass for a glossy finish.
• 📊 Calibrate print temperatures, generally starting at 200°C for the nozzle and 70°C for the bed, adjusting as needed based on the filament brand.
• 🔄 When changing filament, heat the nozzle to the appropriate temperature to avoid clogs and ensure smooth transitions.
• 🧼 Regular maintenance of the extruder gears is necessary to prevent jams and ensure consistent extrusion.
• 🧹 Clean extruder gears with a brush to remove debris and filament dust regularly.
• 🔧 If experiencing clogs, refer to specific resources for unclogging techniques to maintain a smooth printing experience.

Q & A

What is PLA and why is it popular for 3D printing?

PLA, or Polylactic Acid, is a commonly used 3D printing material known for its ease of use, vibrant colors, and minimal warping, making it suitable for both beginners and experienced users.

What is the first step to ensure a successful print with PLA?

The first step is to properly level the print bed, which can be done by adjusting the bed screws while using a piece of paper to gauge the nozzle's distance from the bed.

How can you tell if the first layer of a print is set correctly?

You can tell if the first layer is set correctly by observing the skirt; the lines should slightly squish together without smearing, indicating the correct nozzle height.

Is a heated bed necessary for printing with PLA?

No, a heated bed is not necessary for PLA. However, using a blue painter's tape or glass surface can enhance adhesion during printing.

What alternative method can be used to improve adhesion on the print bed?

You can use an Elmer's glue stick applied in a crosshatch pattern on the bed, which helps prints stick better and is easy to clean off afterward.

What temperature settings are recommended for printing with PLA?

A typical starting point for printing PLA is 200°C for the print head and 70°C for the bed, although adjustments may be needed based on the specific filament.

What should you do when changing filament in the 3D printer?

Before changing filament, heat the nozzle to the printing temperature to ensure the filament is molten. Then, pull out the old filament and insert the new one, ensuring a clean transition.

How can you prevent color mixing when changing filaments?

To prevent color mixing, set the extruder to 90°C and gently pull out the filament before fully cooling it, allowing for a clean exit of the old filament.

Why is it important to clean the extruder gear regularly?

Cleaning the extruder gear is crucial to prevent filament dust buildup, which can cause extrusion issues, leading to poor print quality or failure.

What should you do if the nozzle becomes clogged?

If the nozzle becomes clogged, follow specific unclogging procedures, which typically involve heating the nozzle and cleaning it out, as clogs are common in 3D printing.
