15/7/2018 – CCTREE PLA

I got in contact with someone from CCTREE par coincidence.

This person provided me with 2 spools of PLA: 1 white and 1 black. At first they offered me 1 spoolof white. When talking to them, I explained that white is somethimes handling a bit different then other colors. So I’ve got a black spool added without any more questions.

In this review, I’ll test both spools next to each other.

The spools arrived at my place, very well packed from their Amazon UK store. The package was very clean and well packed. The cardboard boxes looked very sober, but clean and professional. The spools were vacuum packed and with a little bag of silicate inside. What concerns the packing, there is nothing negative to say. Then I’ve measured the filament diameter over a 5 meter distance. The black came out with an average of 1.72 mm, the white with an average of 1.68. The latter looks insufficient, but it is consistent and when added the correct value in your slicer, this program can calculate the correct value for the printer to send the correct amount of plastic to the extruder. Both rolls are 1 kilo of filament. The filament is not brittle (some filaments break between your fingers when bending them).

The first test is a temperature tower with 0.2 mm layers. To get some nice prints, you’ll need this info and this can be different from brand to brand, even different colors of the same brand can have better results on different temperatures.

The white spool started nicely, but got loose of the bed in the 195° area. I’ve tried this twice, just the same way I’ve tested the black. Therefore I adjusted the test a little for the white and printed with a brim to get better adhesion with the bed.

Both spools gave me the best results in the 200° C range. We needed this info for further tests. There was a little stringing at this height, which I could surely get fixed in the test profile. I don’t do this on purpose, since this profile is getting used for all (future) tests with PLA.



Next up, my calibration part. Testing temperature: 200° C., layers 0.2 . No supports!

White is an unrewarding color here. It’s is difficult to study with the bare eye, and more difficult to study on pictures. The black on the other hand, shows the same results. Very nice bonding, smooth sides for an FDM-printer, very little errors due to the lack of supports.

The black …… WAUW ….. This is my best calibration piece ever, and I printed a number of them.

To finish we check the print quality of our little owls. This time 200°C, but 150 micron layers. Again NO supports!

  • adhesion from the white is less good then the black: brim required for pieces with small contact area to the bed.
  • my preferred temperature: 200° C.
  • I’ve used the temperature towers to test strenght (breaking). The bonding between the layers was very strong and doesn’t break with the bare hands.
  • There is some little stringing. I am convinced that when tuning the profile, I could get these gone completely.
  • With a well calibrated FDM-printer, you  can get real nice, smooth sides.

This filament I would buy for myself and suggest to my friends!

Printed on the Prusa MK2s, layers 0.1 mm.
