In most cases, 3D printing resins expire within 12 months. However, sunlight, heat, and chemical contaminants may make them unusable within days or weeks. Read on for more insights into the shelf life of 3D printing resin.
How long can you keep resin in a 3D printer?
Uncured resin can remain intact in the tank or vat of your 3D printer for many weeks if you keep it away from UV light exposure. The ideal condition for storing uncured resin is a cool, dark place. If the environment is not ideal, the UV resin may last for as short as a few hours or 1-2 days.
Can you still use expired resin?
If your resin does expire, what should you do with it? The good news is that if you’ve stored it appropriately, you can use it without worrying about any resin curing problems. But, it will cure with a yellow tint, so you might want to save it for your projects where the resin color isn’t crucial.
How long does 1kg of resin last for 3D printing?
1 liter of resin can last you anywhere from 5 days to a month of printing. It depends on the layer height you are using for your objects, because a 0.025mm layer height is going to need twice as many layers as a 0.05mm layer height 3D print.
What happens if you use expired epoxy resin?
While WEST SYSTEM® epoxy has a long shelf life, age will eventually affect its handling characteristics and cured strength. When stored for very long periods, hardeners may turn darker (reddish to purple), become thicker and give off more odor. 105 Resin may lose some clarity and also become slightly thicker.
How do you use old resin?
What To Do With Leftover Resin
Does resin yellow over time?
Exposure to UV light is the most common reason for epoxy resin turning yellow. When UV light hits the cured epoxy resin, whether directly or indirectly, the natural process of degrading the polymers within is sped up. This photochemical reaction is responsible for more than just turning the epoxy resin yellowish.
