This guide details the construction and operation of the 'Apple Pie' pump-action AR-15, a 3D-printed firearm designed for 50-state legal compliance. It covers material selection (PLA+ vs. glass-filled nylon), caliber choices (5.56 NATO vs. .300 Blackout), and the benefits of pump-action for suppressed subsonic rounds. The video features insights from recognized designers like Corey (@3D_Arms) and Middleton Made, highlighting their expertise in additive manufacturing for firearms.

This video details a study on Taulman Glass Fiber Nylon's properties after various annealing and moisture exposure treatments. The presenter, an experienced 3D printing enthusiast, tests how air annealing, oil annealing, and ambient humidity affect the material's tensile strength and stiffness. The findings suggest that while annealing improves nylon's properties, moisture significantly degrades them, and oil annealing can mitigate some moisture absorption effects.

This video provides an expert-level overview of various 3D printing filaments, focusing on their suitability for functional parts, particularly firearm components like lower receivers. The instructor, with extensive testing experience, details the properties, pros, and cons of PLA Plus, Carbon Fiber Nylon, Glass Fiber Nylon, Polycarbonate blends, and TPU. He emphasizes Push Plastic Carbon Fiber Nylon as a top recommendation for its balance of strength, heat resistance, and printability, while cautioning against certain other materials like PETG due to poor mechanical properties.

This video details a comprehensive testing methodology for 3D printing filaments, specifically focusing on 3D870 PLA. The instructor outlines steps for calibrating extrusion, determining optimal printing temperatures, and testing impact resistance and tensile strength across different print orientations. An experimental method for assessing high-temperature performance is also demonstrated, highlighting the importance of consistent testing protocols for accurate material property evaluation.

This video compares the strength of 3D printed parts made from Siraya Blue resin versus eSun PLA+. The creator highlights that the testing is not exhaustive but aims to provide insights into the material properties of resin prints when contrasted with a common FDM filament. The focus is on material science and practical application through a comparative analysis.

This YouTube video compares the tensile strength of four common 3D printing filaments: PLA, PETG, ABS, and a Polycarbonate blend. Using a new tensile tester, the video aims to definitively determine which material is the strongest. The description highlights that the results are 'interesting,' suggesting a potential surprise or deviation from common assumptions about these materials.

This YouTube video explores a fundamental question in 3D printing: 'Infill Vs. Perimeters. Which Is Stronger?'. The title and description indicate a comparative analysis of the structural integrity provided by infill patterns versus the outer walls (perimeters) of 3D printed objects. The creator plans to release another video on this subject, suggesting this might be an introductory or part-one installment. The focus is on material science within 3D printing, aiming to determine which component contributes more to overall part strength.
