Adhesion to the print bed is a crucial factor for the success of every 3D printing project. Insufficient adhesion can lead to warped prints or even detachment of the piece during printing. In this article, we will explore effective methods to improve adhesion to the 3D printing bed, ensuring optimal and consistent results.
Preparation of the Print Plan
First of all, it is essential to ensure that the print bed is clean and free of debris. Regular cleaning with isopropyl alcohol or a non-abrasive cleaner can do wonders for adhesion. Additionally, using 3D printing-specific adhesives, such as hairspray or glue sticks, can provide that extra grip needed for problematic materials.
Correct calibration
Precise calibration of the print bed is essential. Make sure the bed is perfectly level and that the distance between the nozzle and the surface is optimal. Inaccurate leveling can cause uneven adhesion and adversely affect print quality.
Using Skirt, Brim and Raft
Skirt, brim and raft are useful tools to improve adhesion:
Skirt: A line or lines printed around the piece that help stabilize material flow and verify initial adhesion.
Brim: A series of additional lines around the perimeter of the piece that increase the adhesion surface area, especially useful for objects with small contact surfaces.
Raft: A thicker base on which the object is built, ideal for materials that tend to warp.
Optimal Materials and Settings
Choosing the right material for the print bed can make the difference. Surfaces such as borosilicate glass, PEI or BuildTak offer excellent adhesion for most filaments. Additionally, properly adjusting slicer settings, such as bed temperature and first layer speed, can significantly contribute to adhesion.
Conclusion
Improving 3D printing bed adhesion is not just a matter of using the right tools, but also understanding and applying the appropriate techniques. By following these tips, you can ensure that your prints are high quality and trouble-free.
