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.

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.
