Tush 380 ACP is a semi-automatic handgun model specifically engineered for 3D printing. It is designed to chamber the .380 ACP (9×17mm) cartridge, a popular round for self-defense known for its manageable recoil in lightweight, compact frames
Action Type: Typically utilizes a straight blowback mechanism, which is simple and reliable for low-pressure cartridges like the .380 ACP.
- 3D Compatibility: The model is optimized for FDM (Fused Deposition Modeling) printing using durable materials like PLA+ or Carbon Fiber Nylon to withstand the stresses of firing.
- Capacity: Usually designed for standard pocket pistol capacities .
- Infill Density: Set to 99% or 100%. Use a Gyroid or Cubic pattern to provide multi-directional strength.
- Layer Height: Aim for 0.15mm to 0.2mm. Thinner layers often improve layer adhesion, which is vital for preventing the frame from splitting under recoil.
- Print Orientation: Print the frame rails-down (upside down) or at a 45-degree angle. This ensures that the stress of the slide moving back is not pulling directly against the layer lines, which is the weakest point of a 3D print
- Hardware Kits: The
- Tush 380 is a “hybrid” build, meaning it requires a factory slide, barrel, and lower parts kit (LPK). Never attempt to print the barrel or firing pin
