5. Add a Raft, Skirt, or Brim
If you have read through the sections above but are still having issues, Simplify3D has some helpful features. The software includes built-in options to create sacrificial structures around the first layer of the print. These temporary add-ons are specifically intended to help with first layer adhesion. They can be easily removed and thrown away after the print is finished.
Simplify3D offers three different reinforcement options: rafts, skirts, and brims. These can be found in the Additions tab of the Edit Process Settings dialog box.
· Rafts: A horizontal latticework of filament that is printed underneath a part for better
first layer adhesion.
· Skirts:An outline that surrounds a part but doesn’t touch it. The skirt is extruded on the
print bed before the model starts printing. This helps prime the filament.
· Brims: A special type of skirt (that looks like the brim of a hat) that is attached to the
edges of a model. Brims help prevent warping and improve bed adhesion.

Getting the first layer right is critical to the success of the rest of your print. While first layer adhesion problems are frustrating, many can be eliminated with a level bed, correct temperatures, slower speeds, and proper bed preparation.
