Liquid resins are photosensitive materials used for printing on SLA 3D printers. Resins are also known as photopolymers and they are cured (solidified) by UV light - this also includes sunlight. There’s just THE resin, a base material that can be further enhanced with added colors or additives.
Resins usually consist of three basic components: the core of the resin (monomers and oligomers), photoinitiators - molecules reacting to UV light, which initiate the solidifying process, and additives - admixtures that change the color and properties of the resin.
Important safety information
- Wear gloves to avoid direct contact of the resin with your skin
- A simple respirator is recommended
- Keep out of the reach of children and pets
- Shake the bottle well before every use for around 10 seconds (make sure the lid is securely tightened before doing so)
- Wash with water and soap in case the resin gets in contact with skin/eyes
- If you experience itching or any kind of discomfort after skin contact, seek out medical assistance
- Keep away from light, store in opaque bottles
- Keep at room temperature (18°-32°C), lower temperature changes the viscosity of the resin
- Do not store in dusty areas
- Resin produces fumes - keep the room ventilated during printing
- Some people may be allergic to resins - in case you experience any kind of discomfort (itching, rash), stop using the machine and contact a doctor
