18/01/2019 – Kaisertech PLA White review

Browsing around on the internet and you know what comes. You always stumble on something you never saw before.

That’s how I arrived at Kaisertech, a German manufacturer of filament at incredible prices. What did you expect? This was asking, begging, for a review.

Well, what did they send me?

A clean, fresh looking box. On the inside a spool in a vacuum bag that also holds a small package of silicate against moisture. 1 kg filament, where the windings are not the nicest, but certainly not the worst I’ve seen. This is just “average”. What I do like very much is the spool openings. They can be called big. What I mean by that is, they used less plastic to produce the coil and you can better estimate what’s left on the spool. But I miss markings on the side of the spool, with estimated lengths on it. These markings are becoming more and more common use these days. I will pass this remark to the manufacturer.

According to the manufacturer, you get 1 kg netto filament, with a tolerance of 0.05 mm and a diameter of 1.75mm. The temperature window would go from 190°C until 220°C. My measurements on 10 different spots over 5 meters distance where between 1.71 and 1.72 mm. Very consistent with an average of 1.715 mm.

My 1st test is always a temperaturetower with layer height of 0.2 mm.

It appeared that on my Prusa MK2s, the best printing temperature was 205°C. What was very nice: almost NO stringing!

Next up,my calibration cube. Printing on 203°C, layers 0.2 mm, NO supports! This is for all printers a difficult one. Especially at the ends of the balls, where printing goes very horizontal.

Top: Perfect!
Bottom: the usual error in the center due to printing without supports. But one of the best results I’ve seen so far!

Here, the filament already impressed me. The top was as good as perfect. The sharp edges from the cut balls, well, they are sharp. This is one of the best results I’ve ever seen with PLA during this test. The bottom has the usual error in the center, due to printing without supports. I give Kaisertech for this test 10/10.

To finish, I always print the  owls. Again, without supports! Layers 0.15 mm.

Seeing the previous results, I wanted to go a little further testing this PLA..

On Thingiverse I found this. It looked to me a fun print to finish this review. But…… layers 0.15 mm, NO supports, NO infill (except for the tips of the fingers), 3 perimeters. The model was scaled to life size and was 185 mm tall.


  • My best printing temperature: 203° C. 
  • I’ve used the temperaturetower to put force on the model and see if the layers don’t break. The layers a very nicely bonded one to another to be sufficiently strong. Even without the use of infill
  • Stringing is minimal. 
  • With a good calibrated FDM printer, you can get very nice results.
  • I miss the markings on the side of the spool to estimate the remaining length of the filament.

This PLA is the best I have seen so far in this price range. Even filaments that cost double of this, costed me more sweat and effort and didn’t give me this goodlooking result shown.
