Chemical resistance of 3D printable polymers: experiments
This page describes the experiments on the chemical resistance of 3D printable FFF thermoplastics. Literature review on the topic is found here.
Experimental[edit | edit source]
List of chemicals[edit | edit source]
First, the resistance of 3D printable materials at least to the following solvents, acids and solutions is tested:
- Deionized H2O
- Isopropanol
- Acetone
- Hydrochloric acid (HCl), 37%
- Ammonia (NH3), aqueous solution 25%
- Hydrogen peroxide (H2O2), aqueous solution 30%
- Nitric acid (HNO3)
- Phosphoric acid (H3PO4)
- Acetic acid, concentrated
These chemicals are common chemicals used in many laboratories and many semiconductor processing steps, such as in the cleaning of silicon wafers.
Chemical processes[edit | edit source]
- Resist strip
