ABS, or Acrylonitrile Butadiene Styrene, is a thermoplastic polymer that is widely used in various industries, from car production to the consumer goods market, primarily via injection molding and other molding processes. Because of its range of uses, it is the best-selling engineering thermoplastic.[1] It is also a popular material for 3D printing, where it is used in filament form for the fused deposition modeling (FDM/FFF) process.

ABS is a copolymer, meaning it is composed of three different monomers: acrylonitrile, butadiene, and styrene. These monomers contribute to the unique properties of ABS, making it a versatile material for a range of applications.

Acrylonitrile is responsible for the material's strength and rigidity. It is a polar molecule, which allows ABS to have good chemical resistance and dimensional stability. The presence of acrylonitrile in the polymer chain also contributes to the material's resistance to heat and impact.

Butadiene is a non-polar molecule that provides ABS with its toughness and impact resistance. It is a rubbery material that can absorb energy, making ABS more resilient to mechanical stress. This property is particularly important in 3D printing, as it allows printed parts to withstand the stresses they may encounter during use.

Styrene is the third monomer in ABS and contributes to the material's processability and surface finish. It is a non-polar molecule that provides good flow characteristics, making it easier to extrude and process during 3D printing. Styrene also imparts a glossy surface finish to ABS parts, which can be desirable for certain applications.

The combination of these three monomers results in a material with a balance of strength, toughness, and processability. ABS has a glass transition temperature of approximately 105°C (221°F), which means it can maintain its structural integrity at higher temperatures than other common 3D printing materials, such as PLA.[2] This property makes ABS suitable for applications where parts may be exposed to elevated temperatures or require higher heat resistance.

At present, FDM and closely related extrusion technologies are the only major 3D printing processes that use ABS plastic as a raw material. The material is not suitable for other additive manufacturing technologies like SLS or SLA.

ABS Material Properties

  • High Impact Resistance: ABS exhibits excellent impact resistance, making it durable and capable of withstanding external forces.

  • Good Tensile Strength: It has strong tensile properties, allowing it to withstand pulling forces without breaking.

  • Moderate Glass Transition Temperature (Tg): ABS has a moderate glass transition temperature of around 105°C (221°F), making it stable at relatively high temperatures.

  • Chemical Resistance: ABS resists various chemicals, including acids, alkalis, and organic solvents.

  • Low Density: ABS has a relatively low density, resulting in lightweight printed objects.

  • Smooth Surface Finish: It provides a smooth surface finish for printed objects, allowing for aesthetically pleasing results.

  • Moderate UV Resistance: While not highly UV-resistant, ABS can endure moderate exposure to sunlight without significant degradation.

  • Printability: ABS filament adheres well to heated print beds and has good layer adhesion, enhancing its printability.

  • Toxic Fumes: ABS emits toxic fumes when heated, necessitating proper ventilation during the printing process, though research has shown that emissions from ABS filament cause minimal transient pulmonary and systemic toxicity.[3]

ABS 3D Printing Settings and Optimization

For successful ABS 3D printing, specific 3D printer settings should be used. In this section, we will discuss the most important settings and general recommendations for ABS 3D printing. Although slicers like Cura will have pre-loaded profiles for ABS — and even for many manufacturer-specific ABS products — it can help to understand the parameters in case any adjustment is needed.

Print Bed Temperature

One of the most important settings for ABS 3D printing is the print bed temperature. A heated print bed is essential for preventing warping and ensuring proper adhesion of the first layer to the build platform. The optimal print bed temperature for ABS typically ranges from 90°C to 110°C (194°F to 230°F), depending on the specific filament and printer.

Extruder Temperature

Another critical setting for ABS 3D printing is the extruder temperature. The extruder temperature determines how effectively the filament is melted and deposited during the printing process. For ABS, the optimal extruder temperature typically ranges from 220°C to 250°C (428°F to 482°F), depending on the specific filament and printer.

Print Speed

For ABS, a moderate print speed is generally recommended to ensure proper layer adhesion and minimize the risk of warping. Typical print speeds for ABS range from 40 to 60 mm/s, although this can vary depending on the printer and filament. If you experience issues with layer adhesion or warping, try reducing the print speed in increments of 5 mm/s until the problem is resolved.

raftAdding a raft beneath the print can improve first-layer success

One of the biggest challenges with printing ABS is getting the first few layers right. This challenge can be mitigated by adding rafts to your print, allowing any deformities in the build to be offset onto the disposable base structure. While this will add a small amount of time and material usage to the print, the results may be worth it.


Because ABS is prone to warping as it cools, it can help to maintain a consistent and relatively warm temperature around the build. The best way to achieve this is by using an enclosed printer. If your 3D printer has an open design, search for tips on how to build your own DIY enclosure, then leave prints on the bed within the enclosure for several hours before removing them.


For dual extrusion 3D printing, ABS parts work very well with HIPS supports, which can be dissolved using d-Limonene for a clean break with minimal artifacts. Use of HIPS supports allows for the design of more complex overhanging structures.

ABS Storage and Handling

ABS is hygroscopic, meaning it can absorb moisture from the surrounding environment. Excessive moisture in the filament can lead to print quality issues, such as bubbles, inconsistent extrusion, and poor layer adhesion. To prevent moisture absorption, store your ABS filament in a cool, dry place, preferably in an airtight container with desiccant packets. If you suspect your filament has absorbed moisture, you can dry it using a filament dryer or a low-temperature oven before printing.

While ABS is more heat-resistant than materials like PLA, it is still important to store it away from direct sunlight or heat sources to prevent warping or degradation. Ideally, store your ABS filament in a temperature-controlled environment to maintain its quality and performance.

When handling ABS filament, avoid touching it with dirty or oily hands, as contaminants can affect the print quality and adhesion. Use clean gloves or tools to handle the filament and minimize contact with skin. To prevent tangling and ensure smooth feeding during printing, always secure the loose end of the filament to the spool when not in use. This can be done using the provided holes or clips on the spool, or by using a filament clip or holder.

Post-Processing Techniques for ABS 3D Prints

Post-processing techniques can significantly improve the appearance and functionality of ABS 3D printed parts. In this section, we will explore some common post-processing methods and their benefits and drawbacks.

Support Removal

Methods of support removal depend on the support material and thickness. Supports printed in a dedicated, ABS-compatible support material such as HIPS can be dissolved away, leaving minimal blemishing. Supports printed in ABS should be removed using cutting tools, followed by sanding, as with other materials.

Sanding and Polishing

Sanding and polishing are popular post-processing techniques for ABS prints — as well as those made from other materials — as they can improve the surface finish and appearance of the printed object. Sanding involves using abrasive materials, such as sandpaper or abrasive pads, to remove layer lines and imperfections from the surface of the print. Start with a coarse grit sandpaper and gradually progress to finer grits to achieve a smooth finish.

Polishing is the process of using a polishing compound and a buffing wheel or cloth to further refine the surface of the ABS print. Polishing can help to achieve a glossy, mirror-like finish on the printed object, which can be desirable for certain applications, such as display models or decorative items.

While sanding and polishing can significantly improve the appearance of ABS prints, they can be time-consuming and labor-intensive processes. Additionally, care must be taken not to remove too much material or damage the print during sanding, as this can affect the part's dimensions and functionality.

Vapor Smoothing

acetoneAcetone can be used to smooth ABS prints

Vapor smoothing is another post-processing technique that can be used to improve the surface finish of ABS 3D prints. In fact, one of the biggest advantages of ABS filament is the ability to use acetone as a smoothing agent. The process involves exposing the printed part to acetone vapor, which dissolves the surface layer of the ABS material, smoothing out layer lines and imperfections.

To perform vapor smoothing, place the ABS print in a sealed container with a small amount of acetone. The solvent will evaporate, creating a vapor that reacts with the surface of the print, smoothing out layer lines and creating a glossy finish. The duration of exposure to the vapor depends on the desired level of smoothing and can range from a few minutes to several hours.

Vapor smoothing offers several advantages over sanding and polishing, including a more uniform surface finish and reduced labor. However, there are also some potential drawbacks to consider. The process can be hazardous due to the use of volatile solvents, so proper safety precautions, such as working in a well-ventilated area and using appropriate personal protective equipment, are essential. Additionally, vapor smoothing can result in a loss of fine details and dimensional accuracy, as the solvent dissolves a thin layer of material from the surface of the print. Careful monitoring of the process and adjusting the exposure time can help minimize these issues.

Painting and Finishing

Painting and finishing are additional post-processing techniques that can be used to enhance the appearance of ABS 3D prints. These methods can be employed to add color, texture, or other visual effects to the printed object, making it more aesthetically appealing or suitable for specific applications.

Before painting an ABS print, prepare the surface by cleaning it thoroughly to remove any dust, grease, or residue. This can be done using a mild detergent and water or a suitable cleaning solution. After cleaning, it is recommended to lightly sand the surface with fine-grit sandpaper to improve paint adhesion.

When selecting a paint for ABS, choose a product that is compatible with the material. Acrylic paints, enamels, and lacquers are commonly used for painting ABS prints, as they adhere well to the surface and provide a durable finish. Be sure to follow the manufacturer's instructions for application, drying times, and any required primers or sealers.


ABS and PLA are popular choices in 3D printing, each with distinct characteristics that impact their suitability for different applications. Along with PETG, they are the most popular entry-level materials for 3D printing, and many beginners struggle to choose between them. Here is a concise comparison of their key differences:

Temperature Resistance

ABS: Glass transition temperature of 105°C (221°F) makes it suitable for high-temperature applications.

PLA: Lower glass transition temperature of 60°C (140°F), making it less resistant to heat.

Strength and Durability

ABS: Tough and impact-resistant, ideal for parts needing mechanical stress resistance.

PLA: More rigid with higher tensile strength, suitable for projects prioritizing rigidity.


ABS: Requires a heated print bed, making it more challenging for beginners and certain 3D printers.

PLA: Can be printed on a non-heated bed, making it accessible and user-friendly.

Environmental Impact

ABS: Derived from non-renewable petroleum resources, not biodegradable, and requires more energy during printing.

PLA: Biodegradable, derived from renewable resources, and generally considered more eco-friendly.


Both ABS and PLA can be recycled, but PLA requires specialized facilities due to its biodegradable nature.

In summary, ABS is preferred for high-temperature and mechanically stressful applications, whereas PLA is more user-friendly and environmentally conscious. Consideration of specific project requirements, environmental concerns, and ease of use guides the choice between ABS and PLA in 3D printing.

ABS Composite Filaments

Due to its affordability, reasonable strength, and good level of printability, ABS is often used as a base material in reinforced composite materials. Such materials have added non-polymer reinforcing materials that can provide added strength, stiffness, or other material properties.

  • Carbon fiber: ABS 3D printing filaments infused with carbon fiber offer increased strength, stiffness, and dimensional stability compared to standard ABS. This makes them suitable for applications that require high-performance parts, such as automotive components or drone frames. However, carbon fiber-infused ABS can be more abrasive, requiring the use of a hardened steel nozzle to prevent wear on the printer's extruder.

  • Glass fiber: Similar to carbon fiber, glass fiber additives can enhance the strength and rigidity of ABS parts. Glass fiber-infused ABS is less abrasive than carbon fiber, making it easier on the printer hardware, but it may still require a hardened steel nozzle for optimal performance.

  • Metallic fillers: ABS filaments with metallic fillers, such as aluminum or copper, can provide a unique appearance and feel to the printed object. These filaments can mimic the look of metal parts while maintaining the ease of printing with ABS. However, they may require additional post-processing, such as polishing, to achieve the desired finish.

  • Flame-retardant additives: Some ABS filaments are formulated with flame-retardant additives, which can improve the material's resistance to combustion. This can be beneficial for applications where fire safety is a concern, such as electronic enclosures or automotive components.
