Ever wondered if your trusty 3D printer could do more than just print plastic? What if I told you it could engrave wood without any hardware modifications? It sounds almost too good to be true, but it’s entirely possible—and surprisingly simple. While makers have long noticed the similarities between 3D printers, CNC routers, and laser engravers, this hack takes it a step further by repurposing your existing machine for a whole new creative task.
Here’s the kicker: this method doesn’t engrave wood in the traditional sense, like a CNC or laser would. Instead, it mimics wood burning. And this is the part most people miss: by leveraging the 3D printer’s hot nozzle, you can create precise burned dots on the wood’s surface. Arrange hundreds of these dots in the right pattern, and voilà—you’ve got a detailed image. Arseniy’s Lab demonstrates this brilliantly in a video using a Bambu Lab A1 3D printer, but the technique works on nearly any FFF/FDM model.
But here’s where it gets controversial: this process isn’t exactly gentle on your printer’s nozzle. You’ll definitely want a spare on hand if you plan to switch back to regular 3D printing afterward. However, the trade-off is worth it for the unique art you can create—and it’s not just limited to wood; materials like leather work too! The key? Custom G-code, since your slicer isn’t designed for this task. Arseniy’s web app (https://arseniys-lab.github.io/wood-engraver/) makes this step a breeze: upload an image, tweak a few settings, and the app generates the G-code for you.
This method doesn’t require altering your printer’s hardware, as long as you can control the homing sequence, bed height, and Z offset. It’s a brilliant way to breathe new life into your machine and explore a fusion of technology and craftsmanship. But here’s the question: Is this a practical workaround or a risky experiment? Let us know your thoughts in the comments—would you try this with your 3D printer, or do you think it’s better left to dedicated tools like CNCs and lasers?
