The resin disposal unit is my submission to the Hope3D competition and helps to solve an issue that will continue to grow just as 3D prtintings popularity will continue to increase.
This unit helps to solve UN sustainable development goal 12.4, responsible consumption and production. In particular, By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment.
With the increasing popularity with DLP and SLA 3D printers, waste management is becoming a greater problem. When you would like to dispose of waste resin or failed prints, you ultimately have two options. You can take the waste resin to a specialist recycling center, which isn't always a viable or practical option. Or you can leave a tray with the waste resin / failed prints out in the sun and let them cure naturally so you can then throw out in the normal trash. The latter option has always left me uneasy as children, animals and the enviroment can still access it.
With this increasing problem in mind I have designed the Resin waste disposal unit. Simply line the inner container with a sandwich bag, place the waste resin and wasted prints inside and then slot into the dispoal unit. The clear vinyl will allow sunlight through so the waste will then cure naturally without harming the enviroment or anyone else. The roof is slanted so rain water can run off and the inner container handle is designed to work as the outer locking mechanism as well. There is also a warning sign to ensure no one pokes there fingers init. This is designed to be mounted on a wall or fence. But in theory this would work inside too if positioned by a window. If you like you can line inside of the unit with tinfoil to help bounce the UV rays around. I'd recommend printing the inner container and unit in PETG as this is primarily designed to work outside.
Once printed please add a clear vinyl or clingfilm on top of the unit, then screw the roof vinyl holder on top to keep it in place. It might help to pierce some holes before you screw in. Small screws will do.
Happy printing and I hope you find this useful. :-)
