**Say Goodbye To 3D Printing Limits With This DIY Hack**

The world of 3D printing has come a long way in recent years, but one major limitation has remained - the size of what can be printed. Consumer-grade printers are typically stationary and have a small fixed workspace, making it difficult to print large items without breaking them down into smaller pieces or pausing the printer to move completed segments out of the way. But two resourceful individuals have found an unconventional solution to this problem: a treadmill.

Ivan Miranda and Jón Schone took an ordinary treadmill and transformed it into an oversized 3D printer, using the rubber belt as a conveyor to print incredibly large pieces, similar to those found in industrial settings. The result is a custom-built machine featuring an extra-large extruder, linear rails, custom wiring, and power modules. This DIY hack allows for the creation of furniture, architectural models, mechanical parts, and more on a scale previously unimaginable.

One of the most impressive features of this contraption is its ability to print large pieces at an angle, while the treadmill belt moves the finished segments away. Miranda and Schone have successfully used it to create a 6.5-foot long plastic girder - a feat that would be impossible with standard consumer-grade printers.

But how did they manage this? The extra-large extruder was uniquely tooled to work with the belt, allowing for precise movements and printing on a single plane at an angle. Integrated stepper motors power the moving parts, delivering smooth and controlled movements unlike those found in standard treadmills. Calibration of the belt's speed to match the printer's output required a lot of trial and error, but the end result is well worth it.

Imagine using this DIY hack to print large items or even single-layered sheets for assembly - it would revolutionize the creation process, making it faster than ever. Gone are the days of waiting hours or even days for prints to complete; with this contraption, you could be printing in minutes or hours.

However, while this DIY hack removes some limitations of 3D printing applications, it might also be a bit too technical for novice users to replicate. Some of the best 3D printing projects for beginners are small, simple, and quick to make - a large 6-foot-plus plastic I-beam might be a stretch for even experienced enthusiasts.

Despite this, Miranda and Schone's DIY hack is an inspiring example of what can be achieved with creativity and resourcefulness. It shows that with determination and ingenuity, the limitations of 3D printing can be overcome, opening up new possibilities for makers and hobbyists alike.
