Introduction to 3D printing bubbles
3D printing has revolutionized the manufacturing industry, enabling the creation of complex geometric shapes and custom products with unprecedented precision. But, like any other manufacturing process, 3D printing is not immune to defects. One of the common problems encountered in 3D printing is bubbling, which can damage the structural integrity and aesthetic appeal of the final product. In this article, we will delve into the causes of 3D printing bubbles and explore the fundamental factors that lead to this phenomenon.
Inadequate adhesion of the bed
One of the main reasons for 3D printing bubbling is insufficient bed adhesion. When the printing bed is not calibrated correctly or the printing surface is not clean, the plastic wire may not stick evenly, resulting in bubble formation. Factors such as incorrect beds, adhering to promoters or using the wrong type of printing surface can exacerbate this problem. To alleviate this problem, it is necessary to ensure proper bed calibration, use a suitable printing surface, and apply an adhesion promoter as needed.
Incorrect printing temperature
Printing temperature plays a crucial role in 3D printing, and incorrect temperatures can cause bubbles. If the printing temperature is too high, the plastic wire will over-melt, creating air bubbles as it cools and solidifies. On the other hand, if the printing temperature is too low, the wires may not melt properly, resulting in weak bonding between the layers and subsequent bubbles. To avoid this problem, it is crucial to calibrate the printing temperature according to the specific filament used and monitor throughout the printing process.
Inadequate cooling
Inadequate cooling can also lead to 3D printed bubbles. When the printing layer is not sufficiently cooled, the plastic wire can continue to melt and expand, resulting in bubbles that can create when cooling. This problem can be particularly problematic in prints with complex geometric shapes or thick walls where these prints may be captured. To alleviate this problem, sufficient cooling must be ensured by using a cooling fan or printing in a well-ventilated area.
Moisture content
Moisture content is another key factor that can cause bubbles in 3D printing. When the plastic wire absorbs moisture from the air, it can lead to the formation of air bubbles as the wire melts and extrudes. This problem is especially problematic in humid environments or when printing with filaments that are easy to absorb moisture. To avoid this problem, the filaments must be stored in a dry environment and desiccant is used to maintain low humidity levels.
Poor quality of filament
Poor filament quality can also cause bubbles in 3D printing. When the filament is of poor quality, it may contain impurities or inconsistent diameters, resulting in uneven melting and extrusion. This may cause air bubbles to form when filament is printed. To avoid this problem, high-quality filaments from well-known manufacturers must be used and regularly check the filaments for signs of damage or impurities.
in conclusion
Bubbling of 3D printing is a common problem and can damage the quality and structural integrity of 3D printing products. By understanding the root causes of bubbles, including insufficient bed adhesion, incorrect printing temperature, insufficient cooling, moisture content and poor filament quality, manufacturers can take steps to mitigate this problem.
