If your 3D print does not stick to the print bed of the Creality K1 Max, it can be due to several factors. Adhesion problems are a common obstacle in 3D printing and can lead to frustrating print failures. Fortunately, there are proven methods to fix this issue. Here you will learn how to optimize print bed leveling, select the right printing temperature, and use suitable adhesion aids like glue or blue tape to improve adhesion.

Common causes of adhesion problems on the print bed

Poor adhesion of the first layer can be caused by various factors:

  1. Incorrectly leveled print bed: The build plate may not be flat, causing the filament to be applied unevenly.
  2. Incorrect printing temperature: If the filament is not heated to the optimal temperature, it may not adhere properly.
  3. Dirty or unsuitable build surface: Grease or dust on the print bed can prevent the filament from adhering.
  4. Unsuitable adhesion agent: Some filaments require additional adhesives or special surfaces to stick to the build plate.

Tips for proper print bed leveling

The print bed leveling is one of the most important factors for successful first layer adhesion. If the print bed is not level, the filament will be applied unevenly and will not stick properly.

1. Use automatic leveling

The Creality K1 Max features an automatic leveling function that greatly simplifies the process. Use this function regularly, especially after transporting the printer or after extended periods of non-use.

  • Go to the menu and select “Auto Leveling.”
  • The printer will automatically position the print head at several points on the build plate and measure the height.
  • After completing the leveling process, you should do a test print to ensure the first layer adheres correctly.

2. Manual fine-tuning and Z-offset

Even after automatic leveling, it may be necessary to adjust the Z-offset. The Z-offset is the distance between the nozzle and the build plate, which affects the thickness of the first layer.

  • Perform a test print and observe the first layer.
  • If the layer is too far from the build plate, the filament will not adhere well. You need to reduce the Z-offset.
  • If the layer is too close to the build plate, the filament will be squeezed, which can lead to clogs. In this case, slightly increase the Z-offset.

3. Check the first layer

Make sure the first layer is applied evenly. The filament lines should slightly stick to each other and be smooth, without visible gaps or excessive thickening.

Choosing the right printing temperature

The printing temperature plays a crucial role in adhesion. If the filament is not heated to the correct temperature, it cannot properly stick to the build plate.

1. Optimal printing temperatures for different filaments

Each filament has an optimal printing and bed temperature that is crucial for good adhesion. Here are some guidelines for the most common filament types:

  • PLA (Polylactide):

    • Extruder temperature: 190-220°C
    • Bed temperature: 60°C
    • PLA is relatively easy to print and adheres well to most build plates. However, if the filament does not stick, the temperature might be too low.

  • ABS (Acrylonitrile Butadiene Styrene):

    • Extruder temperature: 230-250°C
    • Bed temperature: 90-110°C
    • ABS tends to warp when cooling, so a higher bed temperature and possibly a closed print chamber are advantageous.

  • PETG (Polyethylene Terephthalate Glycol):

    • Extruder temperature: 220-250°C
    • Bed temperature: 70-80°C
    • PETG adheres well but sometimes tends to stick too strongly to the build plate. A release layer like Blue Tape can be helpful.

2. Print temperature tower

To find the ideal temperature for your filament, it is recommended to print a temperature tower. Such a test print consists of several layers printed at different temperatures. This way, you can determine which temperature offers the best adhesion and print quality.

Suitable adhesion aids for the print bed

Sometimes leveling and the correct temperature are not enough, and additional adhesion aids are needed to improve adhesion on the build plate. Here are some of the most common methods:

1. Glue stick

A simple glue stick (like Pritt) is a cost-effective way to improve adhesion. Apply a thin layer of glue to the build plate before starting the print.

  • Advantages: Easy to use and easy to remove.
  • Application: Especially useful for materials like PLA and ABS, which may not adhere well to the smooth surface of the build plate.

2. Blue Tape (Painter's Tape)

Blue Tape, also known as painter's tape, is a popular choice for many 3D printers. The tape provides a rough surface that filament can adhere to well.

  • Advantages: Good adhesion and easy to remove without leaving residue.
  • Application: Ideal for PLA and PETG, which sometimes have trouble sticking to glass or metal plates.

3. Hairspray

Another simple and effective adhesion aid is hairspray. Apply a thin layer to the print bed to improve adhesion.

  • Advantages: Easy to apply, especially on glass beds.
  • Application: Hairspray works well for PLA, ABS, and other common filaments.

4. BuildTak or PEI sheets

For a permanent solution, you can stick a BuildTak or PEI sheet onto the print bed. These surfaces, specially designed for 3D printing, offer excellent adhesion for a variety of materials.

  • Advantages: Very durable and allows many prints without renewal.
  • Application: Ideal for advanced users and printers that are frequently changed.

Cleaning the print bed

A clean build plate is crucial for the first layer adhesion. Oils or dust on the surface can prevent the filament from sticking.

1. Regularly clean the build plate

Clean the print bed before each print with isopropyl alcohol or lukewarm water and some soap to remove oils and residues. If your print bed is glass, you can wipe it with a microfiber cloth.

2. Avoiding fingerprints

Avoid touching the build plate with your fingers as fingerprints leave oils that can affect filament adhesion. Use gloves or make sure to touch only the edges of the plate.

Conclusion

Problems with adhesion on the Creality K1 Max print bed can be frustrating but are easily resolved with the right settings and techniques. Ensure precise print bed leveling, adjust the temperature to the filament used, and use adhesion aids like glue or blue tape if necessary. A clean build plate and using test prints help achieve optimal results.
