SL-15 reliability

anongunner

I recently printed and assembled my SL-15 but I wanted to ask, for anyone who has actually function tested and used the SL-15 in any heavy use scenario. What is the actual reliability of the SL-15? How many rounds can it last before seeing signs of degradation and reliability issues? What heavy stress can the lower endure before seeing cracks in the frame?

More of a heavy use rather than round count issue. Typical failures are due to issues with the print, cracking at layers. With PLA the only failure I would expect is warping if the lower is over heated.

Ensuring good layer adhesion with higher temperature filaments is important, drying, using a heated chamber, and printing slowly are all good.

To answer that question accurately what filament was used when printing as this obviously will make a huge difference. With PLA+ shooting semi and not blasting through 30-60rds as fast as you can it can last for some time. As ive gotten over 500rds with my wildfire without issues. But if you start shooting rapidly allowing the heat to build they can fail pretty quickly.
