Summary of These threaded inserts aren't made for 3D prints (but work amazingly well)

The video discusses the use of various Threaded Inserts for enhancing the strength and functionality of 3D printed parts. The speaker explores different types of inserts, including heat-set options, Riv Nuts, Prong Nuts, and Self-Tapping Inserts, assessing their performance in terms of strength and ease of installation.

Key Technological Concepts and Product Features:

Threaded Inserts: These are used to create strong connection points in 3D printed parts, allowing for multiple tightenings without degrading the thread.
Material Considerations: The speaker tests inserts in different materials (PLA, PTG, and polycarbonate) to understand how material properties affect insert performance.
Infill and Shell Thickness: The optimal settings for infill density (around 30-40%) and shell thickness (4-6 shells) are identified to ensure the printed part is stronger than the insert itself.
Insert Types Tested:
- Riv Nuts: Used for metal applications, performed inconsistently in plastic.
- Zinc Alloy Furniture Inserts: Initially brittle but performed adequately once properly installed.
- Prong Nuts: Very strong but require access from the back of the part.
- Helicoil Inserts: Used for thread repairs, difficult to install and not recommended for 3D printed parts.
- Self-Tapping Inserts: Showed the best performance, especially when printed with proper thread geometry.

Performance Analysis:

Strength Measurements: Various inserts were tested for pull-out force, with Self-Tapping Inserts achieving the highest average strength (3.3 Nm), while Riv Nuts were the weakest (1.2 Nm).
Material Effects: The results varied across different materials, with PTG showing lower torque resistance compared to PLA, while polycarbonate performed well with Self-Tapping Inserts.

Recommendations:

Self-Tapping Inserts: These are favored for their ease of installation and strong performance.
Prong Nuts: Recommended for applications where access from the back is possible, providing a robust connection.
Avoid Helicoils: Due to installation difficulties and precision requirements, these are not advisable for 3D printed parts.
