This 3D printed non-electric humidifier is made out of recycled industrial waste

A humidifier is a device, primarily an electrical appliance, that increases humidity (releases cool mist into the air) in a single room or an entire building. It turns out that the same device can work with no electrical power. Industrial designer Jiaming Liu recently demonstrated that by using clay and 3D printing to fabricate a non-electric air humidifier. The goal of the project was to explore the use of sustainable materials and possible applications for 3D printing clay.

Made up of two parts – an upper part absorbing and evaporating water and a lower part storing up to 500 ml of water -, the device can work with both parts combined in a pair or with one of them, depending on different space requirements.

According to Liu, the use of 3D printing enables to improve the water absorption efficiency. The water absorption part and the water storage part do not need to be separated and can be printed in one piece. The 3D printing clay is made of recycled ceramic powder to shape curve formations.

Water absorption height comparison:
Left 1 – Original clay without additions,
Left 2 – Clay with 30% recycled ceramic powder added,
Left 3 – Clay with 30% recycled ceramic powder added & printed with special structure.

After the service life of the product, the product can be used as recycled clinker to be added to the cyclic production of the next product.
