This page describes the experiments on the chemical resistance of 3D printable FFF thermoplastics. Literature review on the topic is found here.
Experimental
List of chemicals
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
- Resist strip
- RCA1 and RCA2 wafer cleaning processes, both in RT and 80°C
- Al etch
- Si etch
- HF dip
- BHF dip
- Aqua regia
- Piranha
