How often should I maintain my 3D printer?
Weekly: clean bed, check belt tension. Monthly: lubricate Z-rod and linear rails, clean extruder gears. Every 3-6 months: replace nozzle, check all bolts. Annual: deep clean and full inspection.
What parts wear out on 3D printers?
Nozzle (replace every 3-6 months or 500 hours), PTFE tube (yearly), build surface (yearly+), belts (2-3 years), fans (2-5 years). Bearings last years but can wear with heavy use.
How do I clean my 3D printer nozzle?
Cold pull method: heat to 220C, insert cleaning filament, cool to 90C, pull sharply. Or use a 0.4mm needle while hot. Replace nozzles rather than over-cleaning - they cost $1-5.
When should I replace my build plate?
When prints no longer stick despite cleaning and leveling. PEI sheets last 1-2 years with care. Glass beds last indefinitely. Textured surfaces show wear faster. Cost: $10-30 to replace.
