Airwolf 3D printers need proper technique to ensure the best bed adhesion.  Incorrect adhesion can result in the part separating from the bed.  This will ruin a print as the printer is no longer applying plastic in the correct areas.  Airwolf provides Wolfbite, a special liquid that is chemically engineered to adhere to the filament materials.  Airwolf has a guide that outlines which Wolfbite liquid is best for a given filament.
