How to Smooth 3D Printed ABS?

Acetone is used to smooth 3D prints made of ABS. Acetone dissolves ABS – if it is applied correctly, only the corners of the individual print layers dissolve. This results in a smooth surface. The best variant for smoothing ABS is an acetone steam bath (‘vapor smoothing’).

How do I smooth out my 3D printed ABS?

Acetone is a colorless solvent that is mainly used for cleaning purposes. ABS is highly reactive to acetone, and it’s possible to dissolve only the topmost surface of ABS parts by using acetone in vapor form. This completely eliminates any visible layer lines and gives you a clean and smooth surface finish.

How do you smooth ABS filaments?

You can acetone smooth ABS filament & ASA filament, both with acetone liquid or as vapor. They dissolve readily in the liquid, and a concentrated atmosphere of the vapor will eventually have the same effect.

Does acetone smoothing make ABS stronger?

In summary, acetone has a slightly negative impact on an ABS part, specifically its horizontal strength. As we now know, if you need a piece horizontally stronger than usual, you might want to avoid acetone smoothing.

What is acetone Vapour finishing?

Acetone vapor smoothing uses gaseous acetone to dissolve the surface of a print. This ‘acetone bath’ blends the 3D printing layer lines together and results in a smooth shiny finish. Since acetone evaporates quickly even at room temperature, this process can be done slowly without any heating.

How do you acetone Weld ABS?

Acetone works very well since it is just melting the ABS together. I set both parts in a barely wet acetone tray, waited about 2-3 minutes, then compressed them together. They seem to be bonded pretty well.

How do you smooth ASA vapor?

ASA can be smoothed using controlled exposure to acetone vapors (a process called “vapor smoothing”). HIPS can be used as a great dissolvable support material for ASA prints. Consider using the Dense Supports option in Simplify3D for best results.

How do you harden ABS in 3D printing?

Place your 3D printed parts on an oven-safe surface and put them inside. Immediately turn off the oven and any heating element inside it. Leave your prints in the oven until it has cooled down. A gradual cooling will avoid a reoccurrence of the internal stresses.
