Earth Hour 2025: Lights out, glow-in-the-dark on!

On 22 March 2025 at 8:30 pm, it's lights out for one hour again worldwide! Earth Hour is a global signal for more climate protection: some do it out of environmental awareness, others see it as the perfect excuse to finally get to bed before midnight without a guilty conscience. Of course, we at 3DJake are also taking part: we are giving ourselves and our hard-working 3D printers a digital break and flipping the switch.

We use 3D printing sensibly!

Of course, 3D printing needs energy. But with targeted use of materials and conscious printing, it can have a big impact! A broken clip, a lost screw or a defective handle? Simply print it yourself instead of throwing the damaged product away. With creative prints, you can also print functional helpers for everyday life that do not require additional energy!

Let it glow!

Saving energy is important, but the dark doesn't have to be boring! With the glow-in-the-dark filaments from our range, you can bring a glow and fascinating plays of light into the darkness without consuming electricity! So why not be doubly clever?

The glowing filaments store the ambient light and gradually emit it again in the dark. This allows you to print fascinating objects that create magical lighting effects without the need for batteries or a power source.

Glowing ideas: Practical & creative prints with glow filaments

Need some ideas? How about a glow-tastic key ring so you never have to fumble for your front door key in the dark again? Or what do you say to sustainable night lights? Perfect for kids (and adults who are secretly scared of the dark)! We personally think glowing roses are great too. Okay, they don't grow, but they look damn cool. Glow-in-the-dark sockets are a hit! Because, let's be honest, who doesn't frantically grope for the socket in the dark, only to find that it's always close by? (One thing's for sure: mobile phone charging cables and power sockets have an epic feud in the dark, in which we obviously always get the short end of the stick!)

The 3DJake team has taken the plunge and brought some models to life as a source of inspiration:

We're excited!

P.S.: If you're feeling like a moth after Earth Hour and need some more glow - just print yourself some glow-in-the-dark fridge signposts! That way you'll find your midnight snacks even in the dark!
