When it comes to 3D printed builds, they’re often limited in size due to the small build volume of most printers. However, [Ivan Miranda] has always gone big with his builds, and his latest tank design shows that off in spades.
[Ivan] has been working on printed human-sized tanks for years, and his latest revision aims to solve many of the problems that have hampered its performance in the past. A belt drive is the first major upgrade, aiming to improve the reliability of the drivetrain which has been a pain point in the past. The motor mounts also get built out of aluminium this time to help keep things cooler, as melting was a potential concern previously.
The tank’s controls are also upgraded, this time using a simple pedal system to control the brushless motors for easier driving. There’s even a printed seat for better ergonomics. The result is a giant tank big enough for an adult human, with the bonus that it’s now easy to steer and no longer requires [Ivan] to lie down inside to fit.
[Ivan’s] big printers are key to his success on big builds. One new part for the tank weighs a full 5.8 kg, printed in just 2.5 days! We can’t wait to see what giant thing he builds next. Word is the tank will be getting a turret, too. Video after the break.
