Archer has unveiled a 5-axis FDM 3D printing prototype featuring an automatic 4-hotend toolchanging system and a CoreXY motion architecture. The machine utilizes a unique print bed mounted on three independent ball joints, enabling multi-axis tilting to facilitate non-planar layer deposition. Developed by the creator known as multipoleguy, the system incorporates custom firmware to manage purge cycles for tool changes, successfully printing a three-color double helix with only 6 grams of waste across 830 tool swaps. The project currently relies on the in-development MaxiSlicer software to handle the complex toolpath generation required for non-planar geometry.

This development addresses the primary bottleneck in non-planar FDM printing, which is the lack of accessible, integrated software capable of handling complex 5-axis toolpaths. While commercial 5-axis systems exist in high-end industrial DED or hybrid CNC-AM platforms, they remain rare in the desktop FDM segment due to the high barrier of entry for motion control and slicer development. By combining a toolchanger with a tilting bed, this prototype attempts to bridge the gap between standard 3-axis desktop machines and industrial multi-axis manufacturing, offering potential for improved surface finish and structural integrity in parts with complex curvatures.

For the additive manufacturing community, this prototype demonstrates that the hardware complexity of 5-axis printing is becoming manageable for advanced hobbyists and small-scale developers. The immediate challenge for the Archer project is the transition from a custom-coded, experimental slicer to a more robust, user-friendly software environment that can reliably generate non-planar toolpaths. Future iterations will need to prove repeatability and dimensional accuracy in production-grade materials to move beyond the current prototype status.
