PM422 Songbird V3

PM422 Songbird V3 Features

The PM422 Songbird V3 is packed with innovative elements that set it apart in the 3D printing and firearms community. Its single-shot, single-action mechanism ensures simplicity and reliability for users experimenting with printable designs.

Key highlights include:

• Unique Barrel Compression Design: The frame keeps the barrel layers tightly compressed, allowing for a smaller diameter barrel than traditional unsupported 3D-printed models.
• Chambered for .22LR: Perfect for low-cost ammunition, making it an accessible choice for testing and experimentation.
• Community-Tested Durability: Early versions like 1.7 withstood initial test firings, with a printed barrel lasting up to 3 rounds without rupture and a chamber insert version enduring 15 rounds.

This design prioritizes functionality while acknowledging that 100% printed barrels are not built for long-term use, ensuring users approach builds with realistic expectations.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 1-2 days
• Required Experience: Familiarity with 3D printing, firearm assembly, and basic safety protocols

Hardware and Tools Required

Required Hardware

• .22LR ammunition for testing
• Optional chamber insert for enhanced barrel durability (as tested in earlier versions)

Recommended Tools

• 3D printer capable of high-infill printing
• Standard firearm assembly tools (screwdrivers, wrenches)
• Cleaning kit for post-print finishing
• Safety equipment (gloves, goggles) for handling and testing

PM422 Songbird V3 Parts

The PM422 Songbird V3 CAD file includes all necessary components to print a complete single-shot .22LR pistol. Users are recommended to print with 100% infill using durable materials like ABS, as demonstrated in test records with a Rostock Max printer. Special attention should be paid to the barrel and frame components, ensuring precise layer adhesion to maintain structural integrity under compression.

For optimal results, follow the detailed build instructions provided in the PDF guide linked at build instructions. Note that printed barrels may experience issues like casing sticking, as observed during testing, so prepare for potential post-firing maintenance or modifications.

Printer Compatibility & Settings

The PM422 Songbird V3 is compatible with a wide range of 3D printers capable of handling high-infill prints, such as the Rostock Max used in initial tests. ABS filament is highly recommended due to its strength and heat resistance, critical for withstanding the stresses of firing. Print settings should prioritize 100% infill for maximum durability, with careful calibration to avoid layer separation in the barrel and frame.

Ensure your printer bed is leveled and adhesion is strong to prevent warping during long print sessions. Users should also monitor print progress closely, as precision is key to achieving a functional and safe firearm design.

Conclusion

The PM422 Songbird V3 offers an exciting entry into the world of 3D-printed firearms, combining innovative design with community-driven testing and support. With its unique barrel compression system and accessible .22LR chambering, this CAD file is a must-have for enthusiasts looking to push the boundaries of personal fabrication.
