Do you know pearlescent polymer filament?

I was excited about this filament right from the start. I never saw such a visual effect before. Yeah, I know the metallic shine of some of the metal-filaments out there, but this here is a size larger… Depending on how the light shines onto it, it reflects dazzling brilliant or deeply colored. Very fascinating!

This polymer filament prints similar to PLA, but slightly hotter at around 220°C to 230°C, sticks to the PEI-print bed at 90°C, needs much cooling when printing overhangs and after printing it, it is a little bit softer than PETG.


I searched for pearlescent filament in the past and couldn’t find any. This looks very nice.

Great prints. The filament really does have a great effect. PETG is my favorite materials by far. The layer bonding and surface gloss is really hard to beat.

What minimum layer times do you use? I only ask because print speeds are often stated by many people, but due to minimum layer time are rarely reached in real world printing unless parts are large. In my experience, at 230 and 100mm/s in PETG… most all of those prints should exhibit thermal distortion due to small feature layer times. I see a little of it on the front hull of the benchy, but not as much as I might have expected. I know cooling if engineered well can do a lot, but in my experience not enough for sustain real world 100mm/s on features this small.

I love printing fast, but have always thought there might be a better metric for print speed than theoretical max linear speed. Perhaps we should all put average sustained speed, or job completion time as the measuring criteria.

Just something I have been thinking about.

Edit:I just reread the post. I thought you said it was PETG when I first read the description. Do you happen to know what the base material of this filament is made from?


@Eclsnowman Minimum Layertime is 10sec. My printer is capable of printing at 250mm/s and 800mm/s travel, I did a benchy iirc in 11mins and it looked good.

@Rene_Jurack I can see how the compact nature of the Dice and high strength of the frame lends itself to great high speed motion performance. I hope you don’t think I am questioning the validity of your speeds. In fact quite the opposite. I want to know more about how you do it :slight_smile:

Many of my printers are similarly designed to perform well at high speeds. But on the tree frog legs or the benchy cabin area, anything above 80mm/s and the overhang surface finish suffers greatly due to insufficient cooling time. Especially using materials like ABS that do not like active cooling.

Could you share a video, I would love to see it cooling those small features at 100mm/s.

@Eclsnowman I don’t have a video of the pillars right now, but I have done a (very short) video printing the benchy right above the pillars with 140mm/s a while ago. This is without speed-reducing through min. layertime :
In this video the print has a huge lack of cooling, because the fan wasn’t mounted on spot:
It was more like a test of what is possible without much effort…

We even had a BOSS-Challenge (Benchy on super speed) in the german sub-forum of and even got mentioned from 3dbenchy itself:

@Rene_Jurack Ahh I see. Secondary cooling fans to cool the entire print area. That makes more sense on being able to hit those speeds.
