Keep the feedstock dry always in closed containers or sealed bags, humidity might cause degradation of material resulting into poor extrusion and printing quality.
1. Virgin Pellets as Feedstock
Your LILY Kit is optimized to print objects by extruding virgin plastic pellets in various shapes such as cylindrical or spherical up to 5mm in diameter or length. Virgin feedstock raw material is usually consistent in size and shapes offering consistency as well during extrusion processes
2. Recycl3d Plastic as Feedstock
The LILY Kit is capable of utilizing a feedstock made from recycled waste plastic, be it print supports, filament spools or PET bottles. Thanks to one of the markets leading compression ratios the LILY Kit can use irregular sized feedstock with a size of 1 to 5 mm. Even though the LILY Kit can accommodate these irregularities in granule size. The extrusion reliability and quality increases by having consistency in the geometry and plastic type of the recycled feedstock. Meaning sorting the flakes/chunks so that the feedstock consists of consistently sized pieces eg only using 3-5mm chunks/flakes. Non evenly sized granules or irregular chunks can result in extrusion inconsistencies caused by a lack of pressure in the extrusion zone.
