💡 FDM Reality: Unlike a paper printer, desktop 3D printing requires thermal equilibrium, sub-0.1mm micro-mechanical tramming, polymer glass transition tuning, and dry storage to avoid catastrophic layer failure.

The "Garage Dust" Paradox: When replacing a $3 broken plastic part takes 45 minutes of mechanical troubleshooting, 2 failed prints due to warped ABS or clogged nozzles, and 3 hours of noise, casual owners stop using their machines after 4–6 months. 3D printing remains a rewarding lifestyle hobby, not a frictionless household utility.
