SemiFlex performs well as a tough, flexible filament with an exciting combination of pull strength, shock absorption, and print resolution. SemiFlex is a semi-hard flexible filament that comes in several different colors that have a slight sheen after after being 3D printed. Like NinjaFlex, SemiFlex is a premium and high quality filament material capable of opening the door to a wide range of new applications for your LulzBot desktop 3D printer.

Separate Accessory Recommended!
SemiFlex is so flexible it requires either the Flexystruder or FlexyDually Tool Head for optimal printing performance.

Print Surface Recommendation:
SemiFlex adheres exceedingly well to Lulzbots PEI print surface. Lulzbot strongly recommend applying PVA glue (white school glue) directly on the print surface using a glue stick before printing to ensure easy part removal.


Since SemiFlex is harder than other flexible filaments, complex parts like device cases with overhangs, holes, and details are easier to print while still maintaining its flexible nature. SemiFlex also has applications in robotics due to its ability to function as a tread or grip. SemiFlex is more flexible than standard filaments, so the Flexystruder Tool Head is required when printing with it. SemiFlex prints cleanly and more quickly than other flexible filaments, like NinjaFlex. Advanced users can utilize its ability to bind to ABS when using a FlexyDually Tool Head to make prosthetics, live hinges, wearables, and other projects requiring flexible, complex 3D printed items.

  • Time lapsing in OctoPrint (Properly!)
  • Now that we have decked out our Lulzbot Taz 6 3D Printer with a really nice looking acrylic enclosure, I'm just about ready to turn on some serious 3D printing work. But before I dive into that endless pool of fun, it's a good time to take 5 minutes and set up our Taz 6 and it's OctoPrint Server with a bed-mounted camera and light system. That way I can monitor my prints from the other side of the warehouse using OctoPrint, and m...
  • Meet 'Holman' the Ultimate Bluetooth Speaker
  • Who says you can't have it all? Good looks and a great sound! My name is 'Holman" and I'm a Bluetooth speaker in the form of mans best friend - a dog of course! Why is my name Holman? Well, that's the name of the manufacturer of the PVC pipe I used and the name grew on me as I completed the project! Whilst this might look like a complex project if you have access to the metric PVC pipe and a 3D printer I'm actually quite easy t...
  • The Hipster Coaster
  • We wanted to make a interactive display of the fun that can be had with DIY projects to take to Sydney Mini Maker Faire. We decided to do so by utilising the TinkerKit Braccio from Arduino.org, alongside some 3D Printing ingenuity, for an engaging display for all ages. Enter the Hipster Coaster in all its glory.   All the parts were printed seperately on our family of Lulzbot 3D Printers, later stuck together using a mi...
