When the part is removed from the chamber, the acetone component evaporates leaving a glassy-smooth part free of striation, patterning, and visible layer edges, common features in untreated 3D printed parts.

The most hazardous property of acetone is its extreme flammability.

It is a common solvent for rinsing laboratory glassware because of its low cost and volatility.

Acetone is used as a solvent by the pharmaceutical industry and as a denaturant in denatured alcohol.

Although itself flammable, acetone is used extensively as a solvent for the safe transportation and storage of acetylene, which cannot be safely pressurized as a pure compound.

Acetone is used in a variety of general medical and cosmetic applications and is also listed as a component in food additives and food packaging and also in nail polish remover.

Dermatologists use acetone with alcohol for acne treatments to peel dry skin. Common agents used today for chemical peels are salicylic acid, glycolic acid, 30% salicylic acid in ethanol, and trichloroacetic acid (TCA).

Acetone can be produced from the oxidation of ingested isopropanol, or from the spontaneous/enzymatic breakdown of acetoacetate (a ketone body) in ketotic individuals.
