Uncured resin should be disposed of as a dangerous chemical and cured models in a general wasteSLA 3D-printing waste disposal and recycling might not be as intuitive as you might think. Let’s sum up how we deal with resin waste: Uncured resin leftovers should be disposed of with other dangerous chemicals at places designated for it. It cannot be recycled and definitely should not end in general waste. The same rule applies to bottles, paper towels, and models stained with liquid (uncured) resin. However, cured resin (reactoplastic material) is, unlike filaments (thermoplastic material), a non-recyclable material - it belongs in the general waste.
