One of the aspects that is important to consider when 3D printing is safety.
With traditional FDM printing, this primarily relates to fire safety and air quality.
Thankfully, fire safety is not really an issue due to the lack of hot parts.

Toxic Effects
3D printing UV curable resins are an irritant.
Contact with your eyes can lead to permanent damage if not thoroughly cleaned immediately with water.

You should, unfortunately, dispose of any contaminated leather goods or shoes.

Where possible, you could save money and reduce disposal efforts by reclaiming unused resin.
Pour any remaining resin into its original container through a polypropylene or stainless-steel mesh.
see to it to not cross-contaminate different colors or types of resins.
it’s possible for you to also safely dispose of resins by curing them.
Leave resin out in direct sunlight or otherwise expose it to ultraviolet light until it fully hardens.
Hardened resin is perfectly safe to dispose of.
However, be careful not to overexpose the resin as the UV light will eventually break it down again.
