ROSA3D ReFill PCTG in light gray is a technical material from the copolyester family, designed for printing components that require greater resistance, durability, and stability than those made from standard PET-G.

It combines ease of printing with high impact resistance, good thermal resistance, and excellent material clarity. It does not require a heated chamber, making it suitable for both hobbyist 3D printers and more advanced workshop or functional applications.
