Following stellar results in 3D printing with flexible filament - think 3D printed soles or flexy arms -, we decided to put Gyrobot’s skills to test with the #flexmarvinchallenge. And guess what? He didn’t disappoint!
Here’s how he did it:
- Printer: BQ Witbox retrofitted with a Recreus Extruder
- Filament: Green Filaflex from Recreus. The world’s most elastic filament for FDM machines.
- Temperature: 240°C onto plain glass, no heated bed required.
- Z resolution: 0.3mm
- 2 perimeters and 10% square infill option, square infill provides a softer feel than a triangular infill pattern.
- Scaled at 200%
- Sliced using the free CraftWare from Craftunique, with added custom supports see attached images.
Printing with Filaflex presents unique challenges when printing with overhangs and bridges. The bridging ability with a material that is inherently flexible isn’t as easy than with PLA ABS etc. A part cooling fan doesn’t really solidify the extrudate for it to prevent sagging either. For this reason, Flexible Marvin was printed using supports for the angles less than 45 deg and some of the little overhangs such as the ears and eyebrow point.
Using the CraftWare slicer and it’s ability for the user to remove and add/modify support pillars wherever they want to, really helps to dial in exactly what I wanted to print. The custom supports are saved within the overall project file so they can be further modified at a later date. The automatic support option will place pillars according to the overhang angle, but they can be removed from inside hole channels etc, by a simple GUI click of the pillar.
Thanks for walking us through the making process, Gyrobot!
So who’s going to take the challenge next?

This looks great! What is this software you are using? Is it available for Mac as well?
It’s amazing how you barely see any tracks from the support. Thx for the great content @Gyrobot!

This is another test. Also to see how much text will go into the email.
Cheerio,
