Join the Fraternal Order of the Expensive Sounds! This week, we're joined by Mitch from @polarfilament to discuss a massive and costly failure on their production line. When a 35mm extrusion screw meets high pressure and the wrong temperature profile, things go "bang" in a way no business owner wants to hear.
We dive deep into:
- The anatomy of an extrusion barrel failure.
- Why "used" equipment is always a calculated risk.
- The true cost of downtime vs. the cost of parts.
- How Polar Filament handles massive manufacturing setbacks just days before a vacation.
Mitch is one of the few in the industry willing to open his doors and show the "ouchies" behind the scenes. If you want to learn the gritty reality of American-made filament manufacturing, this is an episode you don't want to miss.
Do you like the more industrial-style fails like this one? Let us know in the comments!
