Printing Tips

Similar to all other silk filament, our rainbow silk filament needs to be printed at higher nozzle temperature and lower speed

We suggest you start with following settings and adjust them based on your result.

1. Print speed for perimeters is suggested to be slower than 80 mm/s, slower speed will result in glossy surface finish and stronger layer adhesion. It worth noting, when the parameters are tuned up perfectly, we have no problem getting successful print at 100mm/s. 

2. Nozzle temperature. We suggest you start with 210°C. Our multicolor silk filament is best printed between 200-230°C

3. Part cooling. Because multicolor silk filament needs to be printed at higher temperature, it's important to have proper part cooling to avoid surface defects and warping. However, cooling too fast will weaken the layer adhesion. A careful balance is needed for successful print

4. Fill density: our rainbow filament color changes every 6-8 meters, higher fill density will result in more dramatic color change in the final print, lower fill density will result in more gradual color change in the final print.
