15 3D Printing Tips to Improve Your Parts

Small adjustments make a huge difference in quality.

Before printing

  • Level the bed well.
  • Clean the bed with isopropyl alcohol.
  • Dry the filament.
  • Calibrate the temperature.

If the first layer still lifts even when leveled, the surface itself is usually the problem — a dual-sided PEI sheet fixes this in most cases.

After printing

  • Remove supports carefully.
  • Wet-sand for a smooth finish.
  • Use primer before painting.

Maintenance that prevents failures

A clogged nozzle is one of the most common causes of print failure — keeping a spare nozzle kit on hand avoids losing a whole day waiting for a replacement to arrive.
