Smith3D Silk Rainbow FAQ
Q: How fast do the colors change?
A: The gradient is gradual, so a typical vase will show multiple colors. Very small prints may only show 1-2 colors.
Q: Can I match colors between prints?
A: Not precisely – the gradient continues from where you left off. Each print will have its own unique color combination.
Q: Is silk rainbow as strong as regular PLA?
A: It has similar mechanical properties but is best suited for decorative items rather than functional parts.
