Our PLA+Silk filament is easy to print and the perfect choice if you want your print to have a highly reflective silky finish. We offer brilliant colours with the glossiest silk tones to help you get creative. Some of our favourite silk prints include; vases, figurines, Christmas decorations, earrings, and cosplay items.
PLA+Silk is a filament that will create impressive prints with a glossy silk-like appearance. The silk-like finish is easily achieved with the right temperature setting and it’s important to perform a Temperature Tower print to help determine the optimal print settings with your printer. This is critical as lower temperatures will produce a matte finish and too high a temperature will create over extrusion. You may also consider adjusting your flow/multiplier settings to assist with fine-tuning any over extrusion. Finding the right temperature balance is key for the silkiest finish.
Note: PLA+Silk filament is not food grade.
Great Layer Adhesion;
Our Silk Filament also has excellent adhesion to the build plate. In fact, over the last 12 months, we have tested and printed it directly onto a mirror surface (at 60 degrees) without needing other adhesion materials such as glue. The benefit of printing on glass/mirror is twofold; it is extremely easy to print directly onto its surface (if you have levelled your bed correctly) and also the effect of the printed object touching the glass is magical. The filament takes on a glass-like appearance due to the nature of the silk reflectivity.
When printing our PLASilk on mirror/glass, it is best to wait until the glass has cooled a little prior to removing the object. Removing the object while the glass is still warm, can cause the base of the object to warp as it will cool rapidly when exposed to the cooler air. Another reason to wait for the glass to cool is that the print will come off the surface more easily.
PLAsilk whilst not as strong as regular PLA+ counterpart (due to the dyes used) is quite strong. Part strength can be enhanced by increasing wall count and/or infill.

We have carefully selected the most brilliant colours available to achieve the glossiest silk tones in the following colour options;
Red – A rich red, with a lovely glossy reflection
Purple – A deep purple that captures and reflects light effortlessly (our personal favourite)
Midnight Blue – A dark blue, that is lustrous (close second personal favourite)
Light Blue – A classic silky light blue tone
White – Pure and simple with wonderful reflection
Black – Classic black with glossy tones
Green – A vibrant green with lovely reflection
Dark Grey – A beautiful shade of gunmetal grey
Gold – A Bright yellow gold
Silver – A shiny silver
Copper – A strong copper finish
Our PLA+Silk filament comes in a resealable bag to help protect it from moisture. Like all PLA based filaments, it can absorb moisture from the air which can create brittleness in the filament. We recommend you store unused filament in the resealable bag with a desiccant satchel, making sure you remove as much excess air from the bag while sealing.
- Silk copper and silver are exquisite! Review by Jeremy
I've used many rolls of filament from 3D Fillies, and they've all been excellent. Have mostly been printing RC aircraft with regular PLA+, but have also used a few of the silk filaments for things like vases. The silk filaments are beautiful.
Have just started using the silk copper and silk silver, and it's their quality that prompted me to post this review. They are absolutely exquisite! Have used them to print vases, and the finish is outstanding. It's amazing that a printed plastic can look so much like metal.
I'm now thinking that a plane printed with the silk silver could look very good indeed. Will try this very soon.
Thanks 3D Fillies!
Would be very interested to know if you have any other silk colours planned? (Posted on 21/10/2020)

- Clean finish Review by wiseone
I use it with my Prusa I3 MK3S and get a smooth finish. I keep the printing head temperature to 230C to avoid stringing and get a good result. (Posted on 3/03/2020)

- Great finish and easy to print! Review by Damian
The new silk filaments are great! They were just as easy to print with as 3DFillies' PLA+ and the end result is amazing. They definitely print with a silky/shiny finish. I have tried red, green, blue and purple so far. Purple is probably my favourite at the moment (though that changes after I print with one of the other colours). (Posted on 7/03/2019)
