ImmortalRevolt's ECM System Version 3.5 Parts
The downloadable file includes a set of STL files for key components like the ECM chamber, electrode assembly, and mounting fixtures, all optimized for the newly added .32 auto and 9x18mm Makarov calibers. Recommended print settings involve using high-resolution layers (0.1-0.2mm) to ensure structural integrity during the machining process, with infill at 50-100% for durability under electrical and chemical stress. Material suggestions lean toward PETG or ABS for their chemical resistance and strength, avoiding PLA due to potential degradation in electrolyte environments.
Special printing considerations include orienting parts to minimize supports and ensuring proper bed adhesion to prevent warping, especially for larger chamber pieces. No build instruction PDF is included, so users should reference community forums or general ECM guides for assembly tips.
Printer Compatibility & Settings
This design is compatible with most FDM 3D printers, including popular models like Ender 3, Prusa i3, or similar desktop units capable of handling detailed prints. Recommended materials are PETG or ABS for their robustness in electrochemical applications, with PLA suitable only for non-critical prototypes. Optimal print settings include a nozzle temperature of 220-250°C, bed temperature of 80-100°C, print speed of 40-60mm/s, and cooling fan at 50-100% to achieve smooth surfaces and strong layer adhesion.
Special requirements involve using a printer with a build volume of at least 200x200x200mm to accommodate larger parts, and enabling brim/raft for brim support to prevent overhang issues. No specific calibration is needed beyond standard leveling and adhesion techniques.
Conclusion
ImmortalRevolt's ECM System Version 3.5 delivers exceptional value by empowering users to produce custom rifled barrels for .32 auto and 9x18mm Makarov calibers, combining innovation with practical DIY appeal for firearms enthusiasts. Its unique features promote precision and safety, making it a standout choice for advancing your 3D printing projects. For best results, start with small test prints, consult online communities for tips, and always prioritize safety protocols during assembly and use.
