When it comes to post-processing ABS 3D printed filament, one technique that is utilized is called ABS acetone smoothing. Acetone is used to melt the layer lines, which results in the elimination of the layer lines.
It is well known for its versatility as a chemical solvent, as it is able to dissolve both polar and nonpolar substances. Acetone is a transparent organic liquid that is known for its versatility. Acetone is therefore useful for a variety of applications, including those involving organic and inorganic substances.
A further point to consider is that acetone is miscible with water, which means that it can easily combine with water in any proportion. In spite of the fact that it is an organic substance, acetone is not toxic, which contributes to its widespread application in a variety of fields. As is the case with all polymers, ABS demonstrates resistance to certain substances while being susceptible to them in other situations.
ABS is notable for its ability to dissolve in a wide variety of compounds, which is connected to both its chemical composition and its smoothing properties. is important to note that chloroform and ethylene dichloride are both dangerous substances that call for stringent safety precautions.
A variety of acetones
The selection of high-purity acetone is absolutely necessary when using acetone for the smoothing of ABS surface. The presence of any impurities or moisture in the solvent can cause your 3D prints to produce inconsistent results or even cause damage to them. When performing ABS acetone smoothing, the following is a list of safety gear that you should take into consideration:
In order to protect your hands from coming into direct contact with acetone, you should wear gloves that are resistant to chemicals. Some examples of such gloves include nitrile and neoprene. The chemical exposure that these gloves are resistant to is minimal.
An extinguisher for fire:Acetone is flammable, so is important to have a fire extinguisher close by.
The following is a list of the essential accessories that you will require throughout the process:
You should select a container that is transparent and can accommodate the size of the 3D-printed part you were working on. For the purpose of monitoring the smoothing process, there is a preference for transparent materials.
Step 1: Getting the ABS Part Ready to Use
1. Now, let's get started on the process of smoothing out the acetone
2. The degree of smoothing and application that you achieve is entirely under your control when you use this method
3. The area that you want to smooth out should determine the size of the paintbrush that you use
After dipping the end of the brush into the acetone solution, spread it out in a thin layer across the surface of the 3D-printed component.
Wait until the parts have dried completely before using them after applying acetone.
Prepare a Box for Smoothing
For the ABS vapor smoothing method to be applied, you will require a container that is only partially enclosed in order to contain the acetone fumes that are surrounding the printed part without completely sealing it off from the air.
A Raised Platform should be placed inside the Box.
To ensure that your ABS components do not come into contact with the bottom of the smoothing box, you will need to make use of a raised platform. For the purpose of preventing dissolution, it is imperative that this platform be made of a material that is insoluble in acetone. The lid should then have a few small holes drilled into it. To avoid the potentially hazardous accumulation of pressure, it is essential to avoid completely sealing the box. Maintaining a close eye on it through the transparent smoothing box is highly recommended. The smoothing box should be allowed to fill with acetone fumes for a certain amount of time, which will have an effect on the model. It could take anywhere from ten minutes to two hours. As you continue to smooth more pieces, you will develop a better understanding of the necessary amount of time. Should you decide to paint the piece, you have the option of leaving the hanger in its current position. During the process of painting, it will be useful for holding and suspending things.
