With the continuous popularity of 3D printing technology, ABS filament, as a commonly used printing material, is favored by many users because of its excellent mechanical properties and wide applicability. However, in order to fully utilize the performance of ABS filament and ensure that high-quality parts are printed, the correct storage and handling methods are crucial. This article will discuss the storage and processing skills of ABS filament in detail to help users obtain more satisfactory results in the 3D printing process.

Storage of ABS filament

Sealed preservation: ABS filament is easy to absorb moisture in the air, resulting in bubbles and uneven material ejecting during printing. Therefore, the newly purchased ABS filament should ensure sealed storage, it is recommended to store in a dry, cool place to avoid direct exposure to the sun. If the filament has been opened, it should be used as soon as possible, or put it in a sealed bag and add a desiccant to keep it dry.
Moisture-proof measures: In order to further prevent the impact of moisture on the ABS filament, the filament can be stored in a moisture-proof box or vacuum bag. When stored, ensure that the filament is not squeezed or bent to maintain its good fluidity.
Avoid high temperature: Although ABS filament has certain high temperature resistance, it should still avoid high temperature environment when storing. High temperature may cause the filament to soften, deform, and even affect its chemical properties. In general, the storage temperature should be controlled between 15-30°C.

ABS filament treatment

Preprint processing

Drying treatment: Before printing, if the ABS filament is found to be hygroscopic, it can be put in the oven for drying treatment. The recommended temperature is 70-80°C and the time is 2-4 hours. This can effectively remove the moisture in the filament and improve the print quality.
Preheating treatment: In order to reduce the warping phenomenon in the printing process, the printing platform can be preheated before printing. The preheating temperature is generally set between 90 and 110°C, depending on the printer model and material characteristics.
Processing in print
Temperature setting: The printing temperature of ABS is generally set between 230-250°C, and the bed temperature is set between 90-110°C. When using a new material for the first time, it is recommended to start with the recommended temperature and then fine-tune it according to the print effect. Too high or too low a temperature will affect the print quality.
Printing speed: It is recommended that the printing speed of the bottom layer is set to 30mm/s, and the printing speed of the first layer is appropriately reduced to ensure that the material can better adhere to the platform.
Cooling fan: ABS material is not suitable for excessive cooling, so it is recommended to turn off the cooling fan during the printing process, so as not to affect the strength and surface quality of the print.

Post-print processing

Ultrasonic bonding: Using an ultrasonic bonding device to soak ABS parts in alcohol can strengthen the bond between materials and improve the strength of parts.
Oven treatment: Put the printed ABS parts into an oven preheated to 70°C for about 1 hour, which can reduce the shrinkage and deformation of the parts and make them more stable.
Surface treatment: Use sandpaper to polish the surface of the part, remove burrs and unevenness, and then apply primer and topcoat to make the surface more smooth and beautiful.

Brief summary

Correct storage and processing of ABS filament is an important link to ensure the quality of 3D printing. The service life of ABS filament can be extended effectively by sealing preservation, moisture-proof measures and avoiding high temperature. Before, during and after printing, pay attention to details such as temperature setting, printing speed and surface treatment, which can significantly improve the printing effect and part performance. Hopefully, the suggestions provided in this article will help users achieve more satisfactory results in the 3D printing process.
