Chemical resistance of 3D printable polymers: literature review
This is a literature review for a study on the chemical resistance of 3D printable polymers. This literature review is initially targeted at liquid chemicals which can "attack" 3D printed polymers. In the future gas and plasma attack can be studied but for now it is out of the scope of this lit review.

3D printing materials and their chemical properties
PLA (Polylactic acid)
One of the most used 3D printing filaments. Various vendors and available in multiple colors. Biodegradable, potentially not very resistant to chemicals.
ABS (Acrylonitrile butadiene styrene)
Commercial 3D printing filaments: Inova Co-Polyester, ColorFabb nGen
Resistant to various laboratory chemicals. Quite resistant to acids and bases. Widely used in clean rooms. Is susceptible to oxidation for example peroxides, as it is just a hydrocarbon.
Taulman T-glase is made of PETT.
Should be in the sweet spot of fluoropolymers. Low enough melting point to be printable but chemically very durable. According to some data should be resistant to nearly all room temperature liquid chemiclas used in clean rooms.
Ultem(R) is a commercial plastic which mainly consists of PEI.
Polyethylene terephthalate modified with glycol.
organic polymers can be here taken as the normal What reactions happen in organic polymers in liquids?
List of chemicals
The resistance of 3D printable materials at least to the following solvents, acids and solutions is tested:
- Deionized H2O
- 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.
General level discussion of organic polymers .Focus here in differences of organic polymers, their production, etc
