I. Heated print bed
The most simple solution is to use heated print bed. If you set the print bed temperature just below the melting point of the filament (glass transition temperature of the plastic material), then the first layer will stick correctly to the platform. The print bed temperature is normaly set by sliner software. The recommended temperature of the print bed for your filament you should find on the packaging or on the spool.
