Do not order!

I received the filament with broken spool, opened packaging and water inside the bag. I think anyone able to print knows what that means for your print.

The owner, Selim A****, has two other companies selling filament (filamentwerk, owl-trading), so I have to assume he tries to change names, to avoid bad reviews.

Ordered 2 Filaments.

1st one does not adhise layers on itself, so print always fails.

2nd one is 1.9MM and gets stuck in the printer.

Don't by OWL Filament!
Even AliExpress is 10 times better!

Wish I had read these reviews as I would have never ordered from this bunch of cowboys. I can't say what the filament is like as I have still not received it. DPD says wrong or missing custom documentation so returned back to sender. Numerous messages and emails have remained unanswered. Luckily I am only down £30 but that's not really the point...expect better from a German company.

So my advice is AVOID this seller at all costs. Trust me please don't purchase anything from this company as you may end up out of pocket...!!!

Spools are brittle and quality is not consistant. Some spools print just fine, some will clogg nozzle after few minutes of printing. Drying doesn't help, so it's not moisture. Same filament, same color, some work some don't.

I bought 2 spools of filament. Both arrived broken to the point that the filament was unusable. In addition I noticed numerous pumps and lamps on the filament. The width varies. I did try to contact the vendor but all my messages were ignored!
I ended-up completely loosing my money!

I have ordered 20 spools of OWL filament for 3D printing. Since receiving them, I have tried printing filament from the 20 spools. It's a slow process, which involves testing, temperature tuning and other specific activities. There are insurmountable issues with the material received, detailed below:
1. Inconsistent diameter. Anything from 1.66 mm to 1.93 mm or above in places, trending towards being thicker, rather than thinner (measured using a digital caliper).
2. Bent filament on the spool. By that, I mean the filament is straight and suddenly has a small "dent" in straightness, bends a little towards a side, then back. This adds more friction in the whole extruding system.
3. Blobs on the filament. I mean... GIANT blobs. Some were 2.79mm in diameter...
4. It doesn't heat up quickly enough. I have tested at temperatures up to 270 degrees Celsius, using a very simple method: heat nozzle to temperature, send "G1 E100 Fnnn" to printer. "nnn" is the feed rate in mm/minute. Printer starts extruding, and I can see reported nozzle temperature starting to drop, and extruder starts skipping. Feed rate was as low as 120mm/minute, which is very, very slow. I have cross-checked with known filament (DevilDesign Black PETG), which had no problem extruding at 120, 240, 360, 480 and 600. All that, using a 0.25mm and a 0.4mm nozzle. All spools were placed in a dehydrator for 24h before using, and were tested immediately after drying. The 3D printer I am using is a high performance printer, and none of the numerous other brands I have been using are exhibiting these issues. I have contacted the trader and I have received no response to my request.
Created disputes at both the EU Customer Protection authority and PayPal.

NEVER BUY OWL FILAMENT!
Also, create disputes if you got burned.

Diameter tolerance is way more than 0.05. Quiet often I had a diameter of 2.00.
