Smoothening 3D Printed ABS with Acetone: A Comprehensive Guide
Introduction
Acrylonitrile Butadiene Styrene (ABS) is one of the most widely used materials in 3D printing. However, one of the drawbacks of using ABS is the rough and layer- lines-prone surface finish. This is where acetone comes in – a solvent that can be used to smooth out the surface of 3D printed ABS parts.
What is Acetone?
Acetone is a colorless, volatile, and flammable liquid solvent. It is commonly used as a solvent in various industries, including 3D printing. In the context of 3D printing, acetone is used to dissolve and smooth out the surface of ABS parts.
How to Smooth 3D Printed ABS with Acetone
Materials Needed
- 3D printed ABS part
- Acetone
- Glass jar or container with a lid
- Paintbrush or foam brush
- Soft cloth or paper towel
- Optional: sandpaper or a sanding block
Step-by-Step Instructions
- Prepare the Acetone Solution: Pour a small amount of acetone into a glass jar or container. The amount of acetone needed will depend on the size of the 3D printed part.
- Soak the Part: Submerge the 3D printed ABS part in the acetone solution. Make sure the part is fully covered by the solvent.
- Wait: Let the part soak in the acetone for 15-30 minutes. This will allow the solvent to penetrate the surface of the part and start breaking down the layer lines.
- Brush Off Excess Acetone: Use a paintbrush or foam brush to gently brush off any excess acetone from the part.
- Wipe Down: Use a soft cloth or paper towel to wipe down the part and remove any remaining acetone residue.
- Inspect and Repeat: Inspect the part for any remaining layer lines or rough spots. If necessary, repeat the process to achieve a smoother finish.
Tips and Variations
- Use a well-ventilated area: Acetone is a volatile solvent and can be harmful if inhaled. Make sure to work in a well-ventilated area.
- Avoid over-soaking: Soaking the part for too long can cause it to become brittle or deform.
- Sand after acetone treatment: For an even smoother finish, use sandpaper or a sanding block to gently sand the part after acetone treatment.
- Experiment with acetone ratios: You can experiment with different acetone-to-water ratios to achieve the desired level of smoothness.
Conclusion
Smoothening 3D printed ABS parts with acetone is a simple and effective way to achieve a professional-looking finish. By following the steps outlined above, you can achieve a smooth and glossy finish that will take your 3D printing projects to the next level.
