Speed up 3D Printing with Fiberflex 40D

Everyone who has tried to print with flexible filaments knows how challenging this can be. Now they can stop complaining. Fiberflex 40D from Fiberlogy is available on the market.

The material is not standard TPU or TPE. However, the information is not officially provided. One thing is sure. Compared to standard flexible filaments that are fed at speeds up to 30mm/s, 20mm/s or even 15mm/s, Fiberflex 40D is a real game changer.

According to the information provided by the manufacturer, it is possible to print with it easily at 45mm/s using a direct drive extruder. Objects with a less complicated geometry may be printed even at higher speeds, even 60 mm/s or 75mm/s. When using a Bowden extruder it is recommended to print at a speed of 30mm/s but this is still an amazing result. Typical flexible filaments cannot handle it at all.

The second feature of this material is its Shore hardness – 40D. Thanks to that the material is stiffer than other filaments. Additionally, the diameter tolerance of +/-0.02mm offered by Fiberlogy makes the feeding much easier. Some users may be surprised by the nonstandard shape of the Fiberlogy spool. The manufacturer’s representative claimed that it was designed to improve the quality of the printing process. That is why it is very handy and, as some users say, „just beautiful”.

The material is now available at 1.75mm and 2.85mm. And the price? As Fiberlogy currently have resellers in Europe, the 0.85kg spool can be purchased there at 43,5 € (this price may vary depending on the VAT rate).

The quality of the Fiberflex 40D has already been appreciated by the online community, for example by Fabbaloo.

FiberFlex 40D looks to be a pretty good product. The prints were quite good quality compared to other flexible material I’ve tried.” – Fabbaloo

How about the quality of the print then?

  1.  Flexibility – the hardness of the material makes it stiffer but still flexible. Thanks to that it may be used for a number of applications.
  2. Bed adhesion – the first layer sticks to the bed so well that its removal may be difficult. This is why it is best to heat up the bed up to 110°C first and then remove the print.
  3. Layer adhesion – the printed layers stick together as they should and there are no signs of jamming or similar problems, which is not at all common among flexible materials.

  4. Support – the material properties make it possible to print projects with supports. Support removal is quite easy and once this has been done the print looks very well.

It is worth to note that the owner of the Fiberlogy brand – FIBERLAB company was announced by Polish industry representatives to be the best Polish filament manufacturer of 2016. Currently, their range includes the following filaments: FIBERFLEX 40D, HD PLA, EASY PLA, PLA MINERAL, ABS, FIBERWOOD and HIPS. Taking into account how the company has broadened its offer and distribution network –  it is worth watching them grow. This is yet another Polish company that provides high-quality products. It should be mentioned that Poland is known for other 3D printing brands such as Zortrax and 3DGence.
