3D printing has revolutionized the manufacturing industry, allowing designers and engineers to create complex parts and prototypes in a matter of hours. However, achieving a successful print requires a good adhesion between the printing bed and the material being printed. Without proper adhesion, the printed object may warp, curl, or detach from the bed, leading to failed prints. In this article, we will discuss five ways to increase adhesion of the printing bed on a 3D printer.Clean the Printing BedOne of the primary reasons for poor adhesion is a dirty printing bed. Before each print, it's crucial to clean the bed thoroughly using a mild detergent or isopropyl alcohol. This will remove any dirt, grease, or debris that may have accumulated on the surface. Avoid using harsh chemicals or abrasives that may damage the bed's surface. After cleaning, make sure to dry the bed completely to avoid any moisture that may affect adhesion. Test your cleaning material on the edge of the bed print prior to cleaning the entire surface, to determine how it will affect the bed print. Avoid using diluting agents.  Use a Bed AdhesiveUsing a bed adhesive can significantly improve adhesion between the printing bed and the material being printed. There are various adhesives available, such as hairspray, glue sticks, and specialty 3D printing adhesives. These adhesives create a thin layer between the bed and the material, providing extra grip and preventing warping or detachment. However, be careful not to apply too much adhesive, as it can affect the overall quality of the print and the cosmetic look of your 3D Printer. Painters tape is a great addition. When using painters tape, make sure to level your bed correctly after taping your printing area since it has a small thickness that can affect your leveling. Adjust the Bed LevelingProper bed leveling is crucial to achieving a successful print. If the bed is too close to the nozzle, it can cause the material to stick too firmly to the bed and may result in difficulty in detaching the printed object. Conversely, if the bed is too far from the nozzle, it can lead to poor adhesion. Make sure to adjust the bed leveling regularly to ensure it's at the correct distance from the nozzle.Increase the Bed TemperatureAnother way to increase adhesion is to increase the bed temperature. Some materials, such as ABS, require a higher bed temperature to adhere properly. However, it's essential to stay within the recommended temperature range for the material being printed. Increasing the temperature too much can cause the material to warp or deform, leading to failed prints.Use a RaftA raft is a thin layer of material that is printed first and provides a stable base for the rest of the print. Using a raft can help improve adhesion, especially for large prints. It also provides a level surface for the object to be printed on and prevents warping or detachment. However, using a raft can increase the overall print time and use more material.In conclusion, achieving a successful 3D print requires a good adhesion between the printing bed and the material being printed. By following these five ways, you can improve adhesion and prevent failed prints. Remember to clean the bed, use a bed adhesive, adjust bed leveling, increase the bed temperature, and use a raft when necessary. With the proper adhesion, you can create high-quality 3D prints with ease.
