Troubleshooting ABS Filament Warping: How to Prevent it

ABS filament is a popular material for 3D printing. It is known for its sturdiness and durability, has a wide range of applications, and is popular among 3D printing enthusiasts. However, working with ABS filament has certain challenges and it is not completely beginner-friendly like PLA filament. Even users with 3D printing experience are easily troubled by warping when they first start using ABS filament. The print temperature setting for this material is crucial, otherwise it is difficult to avoid the warping problem with ABS filament. In this article, we will explore this issue, offering several methods and tips for solving ABS filament warping.


What is ABS filament?

ABS, acrylonitrile butadiene styrene, is a thermoplastic polymer. The advantages of ABS filament are its excellent durability, good impact resistance and temperature resistance, as well as its versatility. ABS filament is versatile and suitable for making functional prototypes or final parts. ABS filament is also a very good choice when users need 3D prints that can withstand mechanical stress and impact.


What is ABS warping? Some problems may occur during the 3D printing process, which affect the aesthetics, quality and structural integrity of the 3D prints, and warping is one of them. Warpage is closely related to bed adhesion and print temperature. Usually, if the printing platform is not flat, the bed temperature is not high enough, etc., it can cause 3D prints to warp. ABS has high requirements on printing temperature and heating bed temperature. It requires a heated bed to maintain high temperature and prevent warping of the initial layer. Common causes of ABS filament warping include insufficient adhesion to the print platform; the hot bed needs to be leveled; cooling is too fast or uneven; and the ABS filament is damp.

ABS printing temperature. Compared with materials such as PLA, ABS filament has a higher melting point, and it is usually necessary to set a printing temperature of 220°C to 250°C, that is, the nozzle temperature. When the nozzle temperature is insufficient, the ABS filament melts insufficiently, which may cause problems such as poor adhesion between layers and cracking of 3D prints. ABS is temperature sensitive and can easily deform, especially during the cooling process. In order to prevent rapid cooling of the first few layers, printing ABS filament requires setting the heat bed between 80°C and 110°C, which can effectively prevent warping and ensure printing quality.


How to Avoid ABS filament Warping

Successfully completing 3D printing can be challenging. In the process of printing with ABS, some skills are needed to avoid warping, which will effectively improve the quality and success rate of 3D printing. If you can master testing and fine-tuning temperature settings, you can not only avoid warping problems of 3D prints, but also improve surface fineness and achieve your ideal ABS printing effect. Next, we will introduce several methods and tips to help you troubleshoot ABS printing problems and avoid ABS filament warping again.

Method 1: Adjust the Heated Bed

Check or re-level the heated bed: If the heated bed is not level, there will be areas where the nozzle and build platform are too far apart and the filament will not bond well, easily causing warping. It is recommended to check if there are any loose moving parts and re-level the heated bed to ensure ABS printing quality. In addition, the surface of the heated bed needs to be cleaned regularly, otherwise it will lead to poor adhesion of the printing bottom layer and affect the printing success rate.

Method 2: Adjust the Pirnting Temperature

Adjust the correct printing temperature: the nozzle temperature for printing ABS filament is 220-250°C, and the hot bed temperature is 80-100°C. Please adjust according to the specific printing model. It should be noted that ABS is temperature sensitive. Minimizing the impact of ambient temperature on ABS printing will help prevent uneven cooling and model warping or deformation. Effective methods include using an enclosed FDM printer or creating an enclosure around the 3D Printer to ensure a stable and warm printing environment.

Method 3: Use Adhesive

Use adhesive: Tall, thin prints tend to warp, and corners of large base layers tend to warp. The geometry of the printed model can also contribute to warpage issues. The use of adhesives can directly enhance the adhesion of the heat bed and reduce ABS warping. There are many specialized adhesives on the market, and using them is also one of the common methods to avoid warping in 3D printing.

Method 4: Optimize Printing Settings of ABS Filament

Optimize printing settings: In addition to printing temperature, during the slicing process, we can adjust the printing settings to optimize the printing effect and avoid problems such as ABS warping. Reducing the printing speed of ABS filament can enhance layer adhesion and reduce warpage. When printing ABS, consider turning off the cooling fan for more even cooling and adhesion. Adding a raft or brim when slicing is also a common 3D printing setting to avoid warping.

In Conclusion:

Using ABS filament to complete 3D printing is a worthy challenge. This material is very suitable for making durable 3D prints and is suitable for a variety of applications. It is easy to encounter warping problems when using ABS filament, but it is not complicated to avoid and solve this problem. Mastering the four skills mentioned above and improving the ability to test and adjust printing temperature will effectively avoid ABS filament warping and improve the success rate and quality of your 3D prints.
