5-Axis Open Source Printer Features Proprietary Slicing Software
The Fractal 5 Pro, an open-source 5-axis 3D printer, is set to revolutionize the world of multi-axis printing, making it more accessible for home users. This innovative device is the brainchild of Fractal Robotics, and its key features are inspired by the Core-XY Voron Trident design.
At its heart, the Fractal 5 Pro uses a robust 30x30 mm aluminum profile frame. The printing process is facilitated by a BondTech extruder in conjunction with an E3D Volcano hotend. What sets the Fractal 5 Pro apart from other 5D printers is its unique addition of two rotational axes, A and B, under a circular build platform.
The A-axis allows the build plate to rotate infinitely, thanks to integrated slip rings. On the other hand, the B-axis permits the build plate to tilt up to 90 degrees, offering greater flexibility in part orientation. This configuration is particularly beneficial for tackling challenging overhangs and optimizing mechanical properties.
The print head on the Fractal 5 Pro has been meticulously designed, ensuring the nozzle can get as close as possible to the build plate, even at maximum B-axis tilt. However, the E3D hotend serves as the limiting factor in determining the nozzle's proximity to the platform.
The Fractal 5 Pro's innovative capabilities are further amplified by its companion slicer, Fractal Cortex. Written entirely in Python, this slicer is optimized for 5-axis printing rather than traditional 3-axis.
One of its standout features is the ability for users to define "slicing planes" aligned with the component’s geometry. When changing slicing planes, the printer pauses to realign the A and B axes before resuming standard horizontal layering. Fractal Cortex also supports a legacy 3-axis mode but primarily aims to unlock the potential of multi-axis 3D printing.
Both the Fractal 5 Pro and Fractal Cortex projects are fully open source, with resources available on GitHub for developers and users to experiment and improve the ecosystem. Contributors are encouraged to join the project, with Danial seeking active participation.
In summary, the Fractal 5 Pro and Fractal Cortex offer a rare integrated solution that combines advanced hardware mechanics and custom software tailored to the complexities of 5-axis additive manufacturing. For those interested in 5D printing at home, the Fractal 5 Pro and Cortex slicer present an exciting opportunity to explore new frontiers in 3D printing.
