About the shrinkage rate of ABS filament
In the 3D printing process, the shrinkage rate is an important factor that cannot be ignored. The shrinkage rate of ABS materials is usually between 0.4% and 0.9%, which is affected by many factors such as material composition, processing temperature, mold design, and so on. Higher processing temperature may lead to increased material fluidity and increased shrinkage. The design of the mold, such as gate location, runner layout, etc., will also have an impact on the shrinkage rate.
In order to reduce the shrinkage rate of ABS filament, some measures can be taken, such as adding glass fiber or other reinforcing materials to the raw material, which can effectively reduce the shrinkage rate to 0.2-0.4%. In addition, making PC/ABS alloy materials is also an effective way to reduce the shrinkage rate, which can be reduced to about 0.4-0.5%.
Understanding and controlling the shrinkage rate of ABS filament is essential to ensure dimensional accuracy and stable performance of 3D printed products. In the actual production process, it is necessary to consider various factors comprehensively, and reduce product size deviation and deformation by adjusting processing parameters and optimizing mold design.
