I had the chance to test some interesting filaments from Fiberlogy.
Fiberlogy is one of the countless 3D printing companies originating in Poland, and they’ve been making high-quality 3D printer filament for several years now. We tested some Fiberlogy materials in 2017 and were impressed. Now, we try a few more.
Fiberlogy representatives asked if we were interested in testing their material, and of course I responded, “Yes!” However, the next thing I knew a very large box with many different filaments arrived. It’s going to take a while to get through all of it, and this report will examine two more filaments from the batch sent by Fiberlogy.
You can read our previous report on two other Fiberlogy filaments here.
In this report we’ll look at two more filaments from Fiberlogy:
Fiberlogy R PLA
Fiberlogy EASY PET-G
Fiberlogy R PLA
This is a recycled filament, something that I believe will be much more important going forward. Fiberlogy describes R PLA:
“Made from 100% recycled material, this filament is a great way to make your prints more environmentally friendly. R PLA is made only from carefully sourced and verified raw material and it meets the strict standards of Fiberlogy filaments, which makes it extremely easy to use on any FDM printer.”
I had some difficulty with this filament, but eventually figured out what was going on. Using default settings, I encountered a number of mysterious print stalls.
I suspected there might be a temperature problem as I tweaked the running nozzle temperature while printing a 100mm cube. In this image the temperature is changed gradually from 210C on the left to 230C on the right. It’s clear there’s a big difference in extrusion quality as the temperature changes.
Eventually, I decided to 3D print a temperature tower. This is a special test model that allows you to change the temperature during the print job to inspect the quality at each temperature. They’re often used to determine the optimum temperature for a given material and 3D printer.
Here’s my result:
It did not work very well. I performed this test three times and received similar results. It seemed that the printer (in this case a Prusa i3 MK2.5S) would stall around 220C.
The recommended temperature range for this material from Fiberlogy is “200-230C”. I ended up performing a test at a whopping 240C, and to my great surprise, it worked perfectly! At this temperature the material performed excellently and never failed. Print results were outstanding.
To ensure that the stall was not caused by another unknown factor, I executed a very long 30-hour 3D print, which completed quite successfully. I now have a giant head for the office staring at me.
Fiberlogy EASY PET-G
I don’t 3D print a lot of PET-G, so I was quite curious to see how this material worked. Whenever you change material you must be concerned with temperatures, nozzle cleanliness and of course bed adhesion.
After setting up all of these factors, I was ready to try Fiberlogy’s EASY PET-G filament. The name “EASY” does set up some expectations for the user, particularly when many other filaments turn out to be challenging to 3D print. Would EASY PET-G really be “easy”?
It turns out yes, it is easy — so easy I could not believe it. Of all the filaments I’ve used over more than a decade, this is perhaps the easiest I’ve ever put through a 3D printer. I’ve 3D printed multiple parts, some quite large, and have not encountered a single problem of any kind:
No filament loading problems (on a Prusa MMU2S, no less!)
No bed adhesion problems (I used a Windex wipe first)
No extrusion problems
No temperature problems (Default print settings used)
No bed release problems
If there ever was a “perfect” 3D printer filament for beginners, this could be it. Every 3D print I attempted not only succeeded but provided near-perfect results.
Successful 3D printing aside, the results are quite spectacular. This incredibly shiny material is able to produce startlingly beautiful objects, such as the “Lumpy Bumpy Vase” by PrusaPrinters contributor BritHawkes.
Incredibly, this print was also waterproof! That is to say, the vase I 3D printed in EASY PET-G was instantly able to hold a full volume of water without any leaks. This is quite notable for a 3D print, which normally are quite porous and immediately leak catastrophically. This vase is functionally useful to hold flowers right off the 3D printer.
Like Fiberlogy’s FIBERSILK METALLIC, their EASY PET-G is best used for objects with flat or gently curved surfaces. It’s more translucent than the FIBERSILK METALLIC, so you can see a bit more deeply into the prints.
As it is PET-G and not PLA, it does offer higher temperature resistance and thus prints made from it are somewhat more useful in hot situations. It’s a great filament to use.
More Filament Reviews Coming
That’s it for now. I’ll be back with further reviews of some additional Fiberlogy 3D prints once my 3D printers cool down a bit.
