ABS plastic is a popular choice for 3D printing due to its reliability and ease of smoothing, which makes it quicker to post-process. There are several methods to smooth ABS plastic, including vapor polishing, sanding, and brushing. Vapor polishing involves exposing the plastic to acetone vapors, causing the outermost layers to melt slightly and resulting in a smooth, glossy finish. This method is quick, easy, and cost-efficient, making it a popular choice for post-processing ABS prints. Sanding and brushing are also effective methods, but they require more time and care to achieve a smooth finish. It's important to note that all of these methods should be performed in a well-ventilated area with the necessary safety equipment, such as gloves, goggles, and a respirator, to protect against harmful chemicals and plastic dust.

What You'll Learn
Sanding
To begin the sanding process, it is advisable to start with a coarse grit sandpaper, typically with a grit size ranging from 60 to 180, to address heavy imperfections, deep scratches, oxidation, or rough edges on the ABS plastic surface. This initial step helps create a uniform base for further refinement. It is crucial to work cautiously with coarse grits as they can be aggressive and remove material rapidly, potentially leading to uneven results if not carefully controlled.
After addressing significant imperfections, the next step is to transition to medium grit sandpaper, usually in the range of 220 to 400 grit. This stage focuses on smoothing out the surface and refining the overall texture of the ABS plastic. It is important to pay attention to the sanding process and ensure that the desired level of smoothness is achieved before progressing to finer grits.
The final stage of sanding involves using fine or ultra-fine grit sandpaper to polish the ABS plastic surface. Fine grit sandpaper typically ranges from 600 to 1000 grit, while ultra-fine grits can go up to 3000. This step brings out a glossy shine and a smooth finish to the plastic surface. Wet sanding is often recommended during this stage as it helps control heat buildup and prevents scratches, resulting in a high-gloss finish.
It is worth noting that some sources suggest starting with a higher grit and gradually moving down in grit size during the sanding process. This approach involves using a hobby knife to slice off as much excess material as possible before sanding. Additionally, it is important to work in a well-ventilated area and wear appropriate protective gear when sanding, as the process may generate dust and debris.
While sanding is an effective method for smoothing ABS plastic, it should be complemented with other techniques such as acetone treatment or heat application for optimal results. These additional processes help smooth and shine the surface further, enhancing the overall finish of the ABS plastic.

Vapor polishing
To perform vapor polishing, start by filing the surface of the ABS plastic with a clean and dry print. Use files solely dedicated to plastic cleanup, as wood or metal particles can contaminate the surface and affect the finish. The filing process breaks down the more aggressive points and layers on the print that acetone alone may not be able to remove.
Next, prepare the acetone bath by pouring about half an inch of pure acetone into a container. Place the container on a hot plate and turn on the heat to a medium setting. It is important to use only pure acetone, as other solvents like nail polish remover may contain additional chemicals that can affect the results.
Once the acetone starts to simmer, suspend the ABS plastic above the liquid using a hanger or another suitable method. Ensure that the plastic does not touch the acetone and that it is high enough to avoid splatters. Cover the container as much as possible to contain the vapors.
Monitor the smoothing process carefully and turn the plastic regularly to ensure even exposure. The plastic will start to soften and become tacky. After 15 minutes, turn off the heat and remove the plastic from the vapors. Hang it somewhere to dry for about 30 minutes until it solidifies.
It is important to note that acetone is flammable and poses safety risks, including skin and eye irritation. Always work in a well-ventilated area and wear protective gear, such as gloves, a respirator, and eye protection. Be sure to have an eye-washing station and a fire extinguisher nearby.

Using a non-reactive container
To smooth ABS plastic using a non-reactive container, you will need a glass or metal container, a non-reactive material to cover your workspace, acetone, a hot plate, safety equipment, and a separate container with water.
Firstly, prepare your workspace by covering it with a non-reactive material, such as metal foil, to protect it from the acetone. Then, find a glass or metal container with a lid, preferably several times larger than your ABS print. Pour about half an inch of acetone into the bottom of the container, ensuring there is enough so that it does not run out during the process. Place your ABS print inside the container, ensuring it does not touch the acetone. You can use a secondary container, string, or aluminium foil to keep your print elevated. If you want to speed up the process, place the container on a hot plate and turn on the heat to the lowest setting.
Once the process is complete, remove the part from the container and hang it somewhere to dry. Do not touch it for at least 30 minutes to allow it to solidify. If you decide it isn't smooth enough, you can repeat the process. Remember to always work in a well-ventilated area and wear safety equipment, such as gloves, eye protection, and a respirator. Finally, rinse off the acetone from your part using a separate container with water.

Rinsing off acetone
When rinsing off acetone, it is essential to work in a well-ventilated area to ensure proper airflow and prevent the buildup of toxic fumes. Wear protective gloves to shield your skin from direct contact with the acetone, and consider using non-latex gloves, as acetone can easily penetrate latex. Safety goggles or glasses are also recommended to protect your eyes from accidental splashes or fumes.
The rinsing process itself can be done under running water, ensuring that the acetone is thoroughly washed away from the ABS plastic surface. Be mindful not to touch or rub the softened ABS plastic with your bare hands during the rinsing process, as it may damage the smoothed surface. Use gentle streams of water and avoid excessive force or abrasion.
After rinsing, allow the ABS plastic to air dry completely in a well-ventilated area. You can hang the piece to dry, ensuring it doesn't come into contact with any surfaces that might affect its shape. During the drying process, the acetone vapors will continue to evaporate, further smoothing the surface.
It is important to note that acetone is a strong solvent, and proper safety precautions are essential when working with it. Always read the manufacturer's instructions, safety data sheets, and precautions before beginning the process. Keep a fire extinguisher nearby and have an eye-washing station prepared in case of any accidents. Additionally, avoid using acetone near open flames or heat sources, as it is highly flammable.

Safety precautions
When smoothing ABS plastic, safety should be a top priority. Here are some detailed safety precautions to follow:
Choose a Well-Ventilated Area:
Work in a well-ventilated area to minimise the risk of inhaling acetone vapours. Acetone can cause headaches, dizziness, nausea, confusion, and skin irritation with prolonged exposure. It is highly flammable and can ignite at room temperature, so keep it away from open flames or heat sources.
Wear Protective Gear:
Always wear safety goggles or glasses with side shields to protect your eyes from accidental splashes or fumes. Wear safety gloves to prevent skin irritation and damage. Additionally, use a respirator mask or a safety mask to protect yourself from inhaling vapours when using chemicals like acetone or spray paints.
Use High-Quality Acetone:
Select high-purity acetone, preferably with a purity of 99% or higher, to ensure it is free from impurities, water, and other contaminants that can affect the smoothing process and the quality of your ABS plastic.
Store and Dispose of Acetone Properly:
Store acetone in a tightly sealed container, away from electrical outlets, stoves, or any heat sources due to its flammability. Dispose of acetone responsibly by using a metal container lined with a plastic bag, then dispose of it with regular trash. For liquid acetone disposal, take it to a hazardous waste treatment facility.
Prepare the Work Area:
Clear your workbench of any debris or particles to ensure the ABS plastic maintains its integrity. Use a drop cloth or plastic sheeting to cover the work area and catch any spills. Ensure the area is well-organised and all safety measures are in place before starting the smoothing process.
Be Mindful of Temperature:
When reshaping ABS plastic by heating, aim for a temperature close to but not exceeding its melting point of 221°F (105°C). Start with a lower temperature and gradually increase it until the plastic becomes slightly flexible. Boiling water can be used safely to reshape ABS without the risk of melting.
Remember, smoothing ABS plastic requires skill and careful handling of potentially hazardous chemicals. Always follow the instructions and recommendations provided by the manufacturers of the products you are using.
