Are you looking for a way to smooth out your 3D printed models? Look no further than the acetone vapor smoothing chamber. This simple yet effective tool can transform your rough, textured prints into smooth, polished masterpieces. In this article, we’ll cover the basics of the acetone vapor smoothing process and how to set up your own smoothing chamber.

What is Acetone Vapor Smoothing?

Acetone vapor smoothing is a post-processing technique that uses acetone to dissolve the outer layer of a 3D printed model, resulting in a smooth and glossy surface. The process is particularly effective on ABS and PLA prints, but can also be used on other materials like PETG.

Why Use an Acetone Vapor Smoothing Chamber?

There are several benefits to using an acetone vapor smoothing chamber. First and foremost, it can significantly improve the appearance of your 3D prints, making them look more professional and polished. Additionally, the smoothing process can help to fill in gaps and imperfections in the print, resulting in a stronger, more durable object.

How to Set Up Your Own Smoothing Chamber

To set up your own acetone vapor smoothing chamber, you’ll need a few key materials. First, you’ll need a container that is large enough to hold your printed object and a small amount of acetone. A glass jar or plastic container with a tight-fitting lid will work well. You’ll also need a platform to hold your object above the acetone, such as a wire rack or a piece of foam.

Step 1: Prepare the Container

Begin by cleaning your container thoroughly with soap and water. Any contaminants or residue could affect the smoothing process. Once the container is clean, pour a small amount of acetone into the bottom, enough to cover the bottom by about 1/4 inch.

Step 2: Set Up the Platform

Next, set up your platform above the acetone. Make sure it is stable and won’t tip over. Place your printed object on the platform, making sure it is not touching the acetone.

Step 3: Seal the Container

Seal the container tightly with the lid, making sure there are no gaps or leaks. You may need to apply tape or sealant to ensure a tight seal.

Step 4: Let the Object Sit

Let the object sit in the smoothing chamber for 10-15 minutes. The length of time will depend on the size and complexity of your object, as well as the temperature and concentration of the acetone. Keep an eye on the object to make sure it is not melting or deforming.

Step 5: Remove the Object

Carefully remove the object from the smoothing chamber and place it on a clean surface to dry. Avoid touching the surface with your bare hands, as this can leave fingerprints or oils that will affect the finish.

Safety Precautions

It is important to take proper safety precautions when using an acetone vapor smoothing chamber. Acetone is a flammable and volatile substance that can be harmful if inhaled or ingested. Always use acetone in a well-ventilated area, and wear gloves and eye protection to avoid skin and eye irritation.


Acetone vapor smoothing is a simple and effective way to improve the appearance and strength of your 3D printed objects. With a few materials and some basic safety precautions, you can set up your own smoothing chamber and take your prints to the next level.
