💊 TODAY’S PRESCRIPTION: CLEAN YOUR BUILD PLATE
Got a print that suddenly won’t stick?
Before you start changing nozzle temperatures, bed temperatures, flow rates, speeds, infill, supports, the phase of the moon… 🫠
Clean your build plate.
Your hands leave oils on the surface every time you touch it. Add dust, filament residue, and whatever else has decided to move into your workshop, and eventually your perfectly dialed-in first layer may start acting like it has never met the build plate before.
🧼 The treatment:
• Let the plate cool down
• Remove it from the printer if possible
• Wash it with warm water and dish soap
• Rinse thoroughly
• Dry it with a clean, lint-free towel
• Try not to touch the printing surface afterward
For routine cleaning, this is often more useful than constantly wiping the plate with whatever solvent happens to be sitting on the workbench.
And remember:
A clean plate gives your first layer a fighting chance.
If you’re still having adhesion problems after cleaning, THEN we start diagnosing the other suspects: first-layer height, bed temperature, filament moisture, plate condition, leveling/calibration, and so on.
🧪 Dr. Layer’s prescription: Before you blame the printer, clean the plate.
What’s the most ridiculous thing you’ve tried to fix a bad first layer before realizing the build plate was the problem? 😂
