9.1. Important information about resins
There’s a couple of things to keep in mind when working with resins:
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
Do not throw resin bottles (empty or full) into regular waste.
Liquid resins should be treated as dangerous chemicals and you should follow your country’s
laws about disposing of dangerous chemicals. There are usually special containers (e.g. oily
waste cans) available for public located near gas stations etc.
9.2. Which resins to buy?
Once you start looking for resins to purchase, always check the
wavelength of the resin
- it
determines at which wavelength the solidifying process starts. The Original Prusa SL1S printer is
calibrated for 405nm resins
and has no brand restrictions. Since it’s an open-source machine,
you can choose any brand of resin you like, as long as it is compatible with the 405nm wavelength.
However, always
use recommended exposure times
for the resin of your choice - extremely
incompatible times may even lead to a damage to your printer (e.g. setting 40 second curing time
