Printing Tips

Similar to all other silk filament, Zyltech multicolor 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. It's also a good idea to start with generic silk profile on most slicers.

1. Print speed for perimeters is suggested to be slower than 60 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 200mm/s. 

2. Nozzle temperature. We suggest you start with 220°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. Top and bottom infill patterns: we suggest concentric and monotonic for the most dramatic and beautiful looks 

5. Spool and filament positioning: It is very important that the filament is routed to the extruder and hot-end without any twists and kinks, and ideally under constant tension. If the filament rotates, there will be undesired vertical banding.

Texas Sky (blue/red) evokes the imagery of the Texas  landscape and its renowned wide, blue skies often complemented by vibrant sunsets, which can be represented by the combination of Silk Blue and Silk Red.

    Dual filament red/black

    Posted by Ryan Martinez on Nov 23rd 2023

    I loved the way the colors came out on this roll but it came tied and I lost 2 projects half way thru. Once I unrolled and then rerolled it everything was great!!
