3D printing is transforming the design world, and it's being increasingly used to create unique artwork, furniture, fashion accessories, and even clothing. In recent years, we've seen a surge in creative applications of 3D printing, especially in the field of lighting design. Many artists and engineers are now using this technology to craft stunning, one-of-a-kind luminaires that would be impossible to produce with traditional methods.
One such innovative piece has recently caught attention: a DNA-shaped lamp created by João Duarte, an electrical engineer from Algarve, Portugal. For under $30, he designed and built a beautiful, moving light fixture inspired by the double helix structure of DNA. The result is not only functional but also visually mesmerizing, making it a true work of art.
Duarte initially stumbled upon 3D models of DNA strands while testing his printer. He was fascinated by how they looked and how they appeared to move when rotated. That sparked the idea for the lamp. “I thought, if something could create a similar illusion, it would be amazing,†he said. With no prior experience in 3D design, he used Tinkercad, a user-friendly software from Autodesk, to bring his vision to life. It took him just a few hours to sketch out the entire concept.
The lamp’s main structure is made from black PLA, chosen for its versatility. To add a magical touch, he used "Glow in the Dark" PLA for the DNA helix, which glows green in the dark. The acrylic casing and internal electronics were added later, while everything else was 3D printed.
Printing the entire lamp took around 14 hours, using two 3D printers — his own DIY Prusa I3 and a printer at a local hacker space. For the electronics, he incorporated a motor inside the base, which slowly rotates the DNA helix within the acrylic tube. LEDs placed at the top and bottom create a soft, gradual lighting effect. An Arduino microcontroller manages both the motor and the lights, ensuring smooth operation.
This affordable, artistic creation proves that 3D printing isn’t just for industrial use — it can also inspire creativity and push the boundaries of what’s possible in design. The DNA lamp is a perfect example of how technology and art can merge to produce something truly extraordinary.
