Disadvantages of ABS in 3D printing

While ABS filament offers numerous advantages in 3D printing, it’s important to be aware of its limitations. Here are some of the key disadvantages associated with using ABS in additive manufacturing:

1. Difficulty in Printing Large Objects:

ABS has a tendency to warp and shrink during the cooling phase, especially when printing larger objects. This can lead to cracking or deformation of the print, resulting in poor dimensional accuracy. To overcome this issue, the use of a heated print bed or an enclosed printing environment is often recommended.

2. Emission of Fumes:

When heated, ABS emits fumes that have a noticeable odor. These fumes can irritate the respiratory system and be harmful if inhaled in large quantities. It is crucial to use ABS in a well-ventilated area or consider using alternative materials if you have respiratory sensitivities.

3. Longer Print Time:

Compared to other filaments, ABS typically requires higher printing temperatures and slower print speeds, resulting in longer print times. This can be a disadvantage if you need to produce 3D prints quickly or have time-sensitive projects.

4. Special Storage Requirements:

ABS filament is hygroscopic, meaning it absorbs moisture from the surrounding environment. If exposed to air for an extended period, the filament can become damp, leading to print quality issues like bubbling or decreased layer adhesion. Proper storage in a moisture-controlled container or using vacuum-sealed packaging is essential to maintain the quality of ABS filament.

5. Limited Flexibility:

While ABS is known for its strength and durability, it is relatively rigid compared to other filaments like TPU (Thermoplastic Polyurethane) or PLA (Polylactic Acid). This lack of flexibility may limit its suitability for certain applications that require more elasticity or ductility.

6. Environmental Impact:

ABS is derived from petroleum-based materials, which raises concerns about its environmental impact. It is not biodegradable and can persist in the environment for a long time. If sustainability is a primary concern, alternative filament options made from renewable resources, like PLA, may be more suitable.

While these disadvantages exist, they can often be mitigated with proper adjustments to the printing process, environmental controls, and careful handling of the filament. Understanding the limitations of ABS filament allows you to make informed decisions and choose the most appropriate material for your specific 3D printing needs.


ABS vs Other Materials in 3D Printing

When it comes to 3D printing, ABS is just one of the many materials available for creating objects. Let’s compare ABS to some other commonly used materials in additive manufacturing to understand their differences and applications.

1. PLA (Polylactic Acid):

PLA is a biodegradable thermoplastic derived from renewable resources like cornstarch or sugarcane. It is known for its ease of use, low printing temperature, and minimal warping compared to ABS. PLA is popular for producing prototypes, consumer products, and decorative items. It is less impact-resistant than ABS but offers good dimensional accuracy and a wide range of vibrant color options.

2. PETG (Polyethylene Terephthalate Glycol):

PETG combines the ease of printing similar to PLA with the durability of ABS. It has excellent layer adhesion, high tensile strength, and good impact resistance. PETG filament is water-resistant and commonly used for functional prototypes, mechanical parts, and food-safe applications. It has similar print settings to PLA, making it a versatile alternative to ABS.

3. Nylon:

Nylon filaments are known for their high strength, flexibility, and durability. They offer excellent chemical resistance and are suitable for producing functional components, gears, and parts requiring high mechanical properties. Nylon requires specific print settings due to its high melting temperature and a need for controlled cooling during the printing process.

4. TPU (Thermoplastic Polyurethane):

TPU filament is a flexible and elastic material known for its rubber-like properties. It is widely used for producing wearables, phone cases, and objects that require high flexibility and impact resistance. TPU offers excellent layer adhesion and can be printed on printers capable of handling materials with low shore hardness.

5. ASA (Acrylonitrile Styrene Acrylate):

ASA filaments are similar to ABS but with improved weather resistance and UV stability. It is commonly used for outdoor applications that require excellent heat resistance and long-term durability. ASA is suitable for producing objects that will be exposed to harsh weather conditions, including automotive parts, signage, and outdoor equipment.

Each material has its unique strengths and weaknesses, making them suitable for different applications. ABS is valued for its strength, impact resistance, and ease of post-processing. PLA and PETG are popular choices for beginners due to their ease of use and availability. Nylon and TPU offer exceptional durability and flexibility, making them suitable for specialized applications. ASA provides better weather resistance compared to ABS.

When choosing a material for 3D printing, consider the requirements of your specific project, including mechanical properties, desired finish, environmental conditions, and intended use. Understanding the characteristics of different materials allows you to select the most appropriate filament for achieving your desired results.


Tips for Printing with ABS

Printing with ABS filament requires attention to specific considerations to achieve optimal results. Here are some valuable tips to help you navigate the challenges of printing with ABS:

1. Use an Enclosed Printer or Build an Enclosure:

ABS is sensitive to temperature changes, and exposure to drafts can cause warping or poor layer adhesion. Using an enclosed printer or creating an enclosure around your printer helps maintain a stable printing environment, minimizing the impact of external temperature fluctuations.

2. Utilize a Heated Print Bed:

ABS adheres well to a heated print bed. Set the bed temperature between 80-100°C to ensure proper adhesion and minimize warping. Applying a thin layer of adhesive, such as glue stick or ABS juice, can further enhance bed adhesion.

3. Fine-Tune Print Settings:

Experiment with various print settings to find the sweet spot for your specific printer and ABS filament. Adjust parameters like extrusion temperature, print speed, layer height, and cooling settings to optimize print quality and minimize issues like stringing or overheating.

4. Consider Using a Brim or Raft:

To prevent warping and improve bed adhesion, consider adding a brim or raft to your print. A brim is a thin border around the base of the print, while a raft is a thicker layer that provides a stable foundation. Both techniques help to distribute the stress and improve print adhesion.

5. Optimize Cooling:

ABS requires limited cooling during the printing process to reduce the risk of cracking or layer separation. Disable or reduce fan cooling for the first few layers, gradually increasing it as the print progresses. This approach helps maintain a consistent temperature and promotes better layer adhesion.

6. Print with Supports:

If your design has overhangs or complex geometries, using supports is crucial to ensure successful prints. Supports provide the necessary structure to hold up these challenging features while printing. Ensure proper support configuration in your slicing software for accurate and reliable prints.

7. Post-Process for Improved Finish:

ABS can be smoothed and finished post-printing to achieve a polished result. Consider sanding the print to remove layer lines or imperfections, followed by acetone vapor smoothing for a glossy and professional appearance. Be cautious when handling acetone and follow appropriate safety measures.

8. Store ABS Filament Properly:

ABS is susceptible to moisture absorption, which can affect print quality and lead to issues like bubbling or poor layer adhesion. Store ABS filament in airtight containers or vacuum-sealed bags with desiccant packs to prevent moisture absorption and maintain its printing properties.

By following these tips, you can optimize your ABS 3D printing experience and achieve consistent, high-quality prints. Remember that experimentation and fine-tuning may be necessary to find the ideal settings for your specific printer and ABS filament.



ABS filament plays a significant role in the world of 3D printing, offering a range of benefits and opportunities for creating functional and durable objects.
