Experimental crossed gantry 3D printer design by @_cybermouse_

This project represents an experimental venture into innovative 3D printer design, with the aim of remodeling an older 3D printer into a high-performance machine while simultaneously honing and testing my 3D design and engineering skills. By incorporating cutting-edge concepts and features, the goal is not only to breathe new life into outdated hardware but also to push the boundaries of what a desktop 3D printer can achieve. This experimental approach underscores a commitment to exploring novel mechanical systems and leveraging advanced design techniques to create a printer that stands out in terms of functionality, efficiency, and precision.

The design features a crossed gantry XY system, which is known for its lightweight and efficient motion mechanics. With four motors driving the XY axis, this setup ensures superior speed and precision. The lightweight, generatively designed toolhead reduces inertia, improving accuracy and acceleration capabilities. A kinematic print bed enables print bead warping correction and presents an opportunity to experiment with non planner 3d printing, while the sturdy frame, constructed from 30x30 aluminum profiles, ensures durability and reliability during high-performance tasks.

Powered by NEMA17 motors on all XYZ axes, this printer operates with a 24V power supply, with the flexibility to upgrade to 48V for enhanced motor performance. The large print volume of approximately 450 x 320 x 320 millimeters makes it ideal for substantial projects, and the enclosed print chamber, application of high-temperature components, lays the foundation for future upgrades like an active heated chamber for advanced materials.

This experimental design not only serves as a playground for innovation but also embodies a commitment to revitalizing older machines while pushing the envelope of personal 3D printing capabilities.

Disclaimer!

This project is still a work in progress! I don’t recommend anyone try to order any of the parts shown here yet. The first batch of prototypes is already in production, but there’s still a long journey ahead. It will involve plenty of testing, assembling, 3D modeling, and refining to bring the design closer to completion.
