June 1: Start with a Brim or Raft for Better First-Layer Adhesion
Introduction
3D print bed adhesion problems? If your prints keep lifting off the bed, poor first-layer adhesion might be the culprit. A brim or raft can significantly improve adhesion, ensuring a strong foundation for your model—especially when working with materials prone to warping like ABS.
Why This Matters
A good first layer is critical for successful prints. When adhesion fails, prints may curl up, detach mid-print, or become uneven. Adding a brim or raft ensures proper bed contact and reduces failed prints.
How to Apply This Tip
✅ Brim – Adds extra filament around the base, increasing bed contact without affecting the model itself.
✅ Raft – Creates a separate foundation layer beneath the model—ideal for warping-prone materials.
? Slicer Settings: Navigate to Build Plate Adhesion in Cura or PrusaSlicer, and select Brim or Raft, adjusting width and separation gap.
Common Mistakes & Fixes
❌ Too thick raft – Hard to remove; reduce raft separation gap in slicer settings.
❌ Brim sticks too much – Try lowering first-layer temperature slightly for better removal.
❌ Still lifting? – Clean the bed properly, ensuring no oils or residue affect adhesion.
