At Maker Build It, we love pushing the limits of 3D printing, especially when magic and tech collide. In this project, we’re creating something straight out of a fantasy novel: a glowing dragon egg that lights up when you “hatch” it. Powered by LEDs and brought to life on the Anycubic Photon Mono M7 Pro, this build combines high-speed resin printing with beginner-friendly electronics. If you’re into props, terrain, or miniatures, this is one fire-breathing project you’ll want to check out.
Why the Anycubic Photon Mono M7 Pro?
The Mono M7 Pro is a beast of a resin printer, and it’s the perfect match for this fantasy-inspired build. Here’s why:
-
14K resolution on a massive 10.1-inch screen (13,312 × 5120 pixels)
-
Sub-50 micron accuracy for ultra-fine details
-
Print speed up to 170mm/hr with high-speed resin
-
Auto resin filling and a temperature-controlled vat (great for thicker resins like Rigid 10K)
-
Intelligent sensors to prevent failed prints
-
Built-in carbon filter to manage odors
And let’s be honest—nothing ruins immersion like running out of resin halfway through your dragon’s tail. The auto-fill alone is worth celebrating.
The Model: Modular Warmling Dragon Egg
We used a modular dragon model from Loot Studios and modified the design to support internal LEDs. The idea: when you lift the top of the egg, a photoresistor senses the light and turns the LEDs on. It’s simple, magical, and incredibly satisfying.
Build Volume and Detail
The Mono M7 Pro’s build volume (223 × 126 × 230 mm) gave us plenty of space for our multi-part dragon egg. We sliced the model in Anycubic’s slicer, which made it easy to:
-
Add drainage holes
-
Adjust wall thickness
-
Generate reliable supports
Print quality? Absolutely stunning. Compared to an FDM version of the same model, the resin print had smoother curves, crisper details, and a professional finish. This is why resin is the go-to for miniatures and props.
Adding the Electronics: Light-Up Magic
To bring the egg to life, we wired up a simple circuit:
Components
-
1 × Photoresistor (LDR)
-
2 × LEDs
-
1 × 9V battery
-
1 × Battery clip connector
-
Solder and iron
-
Shrink tubing (for insulation)
-
Kraken glue with accelerant (for final assembly)
How It Works
It’s like your refrigerator, but in reverse. When the photoresistor senses light, the LEDs turn on. Close the egg (blocking the light), and they turn off. This makes it feel like the dragon is waking up when the egg opens.
We drilled 7mm holes into the back shell to hold the LEDs—slightly larger than the standard 6mm LED diameter. A bit of extra room makes assembly much easier, especially when wiring and gluing everything into place.
Soldering and Setup
The circuit is beginner-friendly, and if you’re new to soldering, I’ve got tutorials on my YouTube channel that walk you through everything. Just be sure to insulate your wires and secure connections before sealing the egg.
Final Assembly
Once everything was wired and tested, we used Kraken glue and accelerant to attach the internal components. The final effect? Glorious. When you lift the top of the egg, the dragon inside glows to life. It’s one of those “wow” moments that really makes all the setup worth it.
Welcome to the World, Baby Dragon 🐉
And just like that, we’ve got a glowing warmling dragon ready to hatch. This project is perfect for:
-
Fantasy prop makers
-
Tabletop terrain designers
-
3D printing enthusiasts who love high-detail prints
-
Anyone who wants to dip their toes into electronics
The Anycubic Photon Mono M7 Pro proved itself as a top-tier resin printer for large, high-resolution builds. If you’re ready to level up your miniatures or terrain game, this printer delivers.
