Overview
This model is a high-strength, reinforced frame designed to chamber and fire large-bore cartridges in a compact, pistol-style configuration.
- Reinforced Frame Geometry: Specifically engineered to withstand the extreme pressures (potentially over 20,000–38,500 PSI depending on the specific caliber like the .450 Bushmaster) through thickened walls and strategic infill patterns.
- Modular Design: Typically includes a removable muzzle brake to help manage the “stout recoil” characteristic of “thumper” rounds.
- Material Compatibility: Optimized for high-performance filaments like Glass-Filled Nylon (PA-GF) or Carbon-Fiber Reinforced PLA, which provide the necessary durability and heat resistance for functional components.
- Compact Ergonomics: Features a shortened barrel assembly and custom grips to maintain a pistol profile despite the massive cartridge size.
In many jurisdictions, manufacturing or possessing unserialized, 3D-printed firearms is subject to strict regulations. For example, the various state laws now classify 3D-printed frames and receivers as firearms requiring serialisation and background checks. Always verify local laws before attempting to print functional models.
