The 3DP90 rifle has emerged as a standout project in the world of 3D-printed firearms. Inspired by the iconic FN P90, this bullpup-style firearm is designed to be assembled at home using a combination of 3D-printed parts and off-the-shelf components. Whether you're a seasoned builder or a newcomer to the world of 3D-printed firearms, the 3DP90 offers an exciting and challenging project.
🔧 What Is the 3DP90?
The 3DP90 is a 3D-printed firearm developed by the group Are We Cool Yet? (AWCY). It replicates the compact and futuristic design of the FN P90, a bullpup personal defense weapon known for its unique top-mounted magazine and ambidextrous controls. The 3DP90 is chambered in 5.7×28mm, utilizing standard P90 magazines. The design emphasizes a high degree of DIY involvement, with components like the bolt requiring assembly from raw materials.
🧰 Components of the 3DP90 Build Kit
Several suppliers offer comprehensive build kits for the 3DP90, each varying in the level of assembly required and included components. Here's an overview of what's typically included:
-
Printed Parts: STL files for components like the receiver, clamshell, trigger housing, and magazine well.
-
Hardware: Items such as screws, nuts, heat-set inserts, and springs.
-
Metal Components: Materials like Cerrosafe for casting the bolt, steel rods, and dowels.
-
Fire Control Group (FCG): An AR-15 FCG, which is adapted for the 3DP90 design.
-
Barrel: A 16" barrel, typically sourced separately.
For instance, the 3DP90 Complete Kit from 3D Print Freedom includes a pre-poured bolt and all other hardware required to complete your 3DP90 build, except the barrel, which is sold separately.
🛠️ Assembly Process
Building the 3DP90 is a multi-step process that requires precision and attention to detail. Here's a general outline of the assembly steps:
-
Printing Components: Using the provided STL files, print the necessary components with a 3D printer.
-
Casting the Bolt: Melt Cerrosafe and pour it into the printed bolt mold to create the bolt body.
-
Assembling the Bolt: Attach steel plates to the bolt body to form the firing pin, extractor, and breech face.
-
Installing the Fire Control Group: Adapt the AR-15 FCG to the 3DP90 design, ensuring proper alignment and function.
-
Final Assembly: Assemble all components, install the barrel, and perform function checks.
Detailed guides and bill of materials are provided with the kits to assist builders throughout the process.
Legal Considerations
Before embarking on building a 3DP90, it's crucial to understand the legal implications in your jurisdiction. In many places, constructing a firearm without proper licensing is illegal. Always consult local laws and regulations to ensure compliance.
💡 Tips for a Successful Build
-
Precision is Key: Accurate printing and assembly are essential for the firearm's functionality and safety.
-
Use Quality Materials: Opt for high-quality filaments and components to ensure durability and performance.
-
Follow the Guide: Adhere strictly to the provided build guide to avoid errors and ensure proper assembly.
-
Test Thoroughly: Conduct thorough function checks in a safe environment before live firing.
The 3DP90 rifle represents a significant achievement in the realm of 3D-printed firearms. It combines innovative design with the DIY spirit, offering enthusiasts a unique project that challenges both technical skills and creativity. While the build process is intricate and requires careful attention to detail, the result is a functional and impressive firearm that showcases the potential of 3D printing technology in firearm design.
