PLA (Polylactic Acid) stands as a versatile and widely used material in 3D printing thanks to its low warping tendencies, great adhesion, low printing temperatures, vibrant color options and odor-free extrusion. Another benefit offered by PLA is its versatility in terms of surface finish. One of the many attractive surface finish of PLA is the silky finish achieved through the incorporation of additives or special processing techniques during the manufacturing process, resulting in a smooth and glossy surface finish of the 3D printed parts.

How to use the Rosa3D masterspool with the refill filament

The eco-friendly refill format significantly reduces plastic usage and contributes to paving a way for sustainable 3D printing. In order to use this PLA Rainbow with a 3D printer, the filament must be wound onto the Rosa3D Masterspool, a smart solution designed specially for the Rosa3D filaments in refill format. This reusable masterspool is made of recycled PC and has an approximately 90 % lower CO2 carbon footprint compared to a standard plastic spool. The masterspool is also resistant to impact and heat, which makes it compatible with filament dryers, as well as AMS systems. Alternatively, solutions such as the F2P variable spool holder can be used.

The recommended printing temperature for the PLA Rainbow filament ranges between 195-225 ºC, and the best bed temperature is 40-60 ºC. The recommended part cooling fan setting is 50-100 %.

Proper storage of the PLA Rainbow filament is essential, as processing damp filament can lead to polymer chain degradation, fragility, poor layer adhesion, stringing, and oozing. It's best to store the filament in a sealed bag with desiccant or in a vacuum-sealed filament container.

Should the filament absorb excess humidity, it should be dried in a filament dryer for 4 hours at 50 ºC.
