New and innovative applications of 3D printing in the household

There are many new and innovative applications of 3D printing in the household, relating to cooking, cleaning, even furniture. We’ve reviewed several of them.


3D printing is leading to many novelties in the culinary sphere. A 3D-printed mold has been developed, in which you can make chocolate. The chocolates are molded so that two flavors that go with each other can fit together precisely like puzzle pieces and be eaten together. What a fun way to entertain guests! Not to mention your kids! (Don’t overdo it with the young ones though).

Countertop Rings Be Gone

Coasters were invented to save us from the unsightly appearance of countertop rings. Now, 3D printers take just a few minutes to print them.


Copying the exterior appearance of wood is an established capability, but it’s been harder to create an accurate interior structure – until recently. Researchers from Columbia University have developed an approach to scanning techniques that has been able to imitate the internal and external structure of wood in combination with 3D printing. They used a real wood block as a template to create the model. First, they sliced it at intervals of 0.027 mm using a CNC (computer numerical control) device, then prepared the images created by the slices for printing using a polyjet printer and 3D printable code.

Why is all this so important? The workflow used by the researchers can be applied to creating 3D-printed copies of other items with complex internal structures that couldn’t be achieved before. This means your furniture can now be printed! No more IKEA!

Windshield Scrapers

No household (except a car-free one) can do without a solid and easily replaceable windshield scraper. If you break your 3D printed one, just have another one printed in a jiffy.


Households rely on security systems (to different extents). 3D printing can supplement and augment home security because a printed sensory device has been created, which is stretchable, can detect motion, and responds to touch.


It’s finally possible to guarantee that no one will insert an item into a power outlet thanks to 3D printed outlet plugs. Apart from safety considerations, 3D printing an outlet lets homeowners get creative with an otherwise mundane item.
