Introducing Gyroid Infill

When it comes to infill patterns, they’re all pretty plain. Grid, rectilinear, honeycomb and cubic. I know there are others, but those 4 are favoured due to their strength and ability to be printed at high speeds. Well now there’s a new kid on the block – Gyroid.

A gyroid is a naturally occurring structure which be found in butterfly wings and even within membranes inside cells. In 2017, MIT researchers discovered that when graphene was shaped into a gyroid structure, it had exceptional strength properties at low densities. They then discovered however, that the crucial aspect of this was actually the gyroid structure itself, and that other materials such as plastic could benefit from this.


Slic3r developer supermerill started working on this, and it’s now been merged into both the regular Slic3r and also Prusa edition. You can download a version of Slic3r with gyroid infill here, and it’ll be in the next Prusa edition release.

I’ll be doing some strength tests with the gyroid infill soon to see how it compares to the other patterns. For now though, here are some gorgeous prints that I did with the gyroid infill showing:

Stay tuned for the strength tests and more videos on Gyroid to come! And be sure to subscribe to my YouTube channel here if you’d like to see more content like this.

  1. it’s nice all the info on the blog… at high speed I can not print the petg without angel’s hair,with petg I assume that the faster you go you have to be hot,the tpu at high speed is a treat,,,, for fast print I have a printer v slot (clone cr) with a rectangle at the gantry,I made lead moldings that are T to be inserted into the profile, with a layer of latex vulcanized underneath and vinyl tape to hold well (I have not screwed everything yet), without it is not possible to print quickly with a cr clone…. (i translate..)


  2. How do you get gcode output from slic3r to make those prints without the perimeters. I have tried all kinds of methods to make prints without perimeters and never managed to find a solution.


  3. Also, what kind of printer you used to print this sample, SLM ? otherwise there requires lots of supporting materials. Thanks Jonathan


    1. This was printed on my Prusa MK2, so using FDM printing. The bridges and overhangs were so small that the printer is able to overcome them. The picture of the pink prints however was taken by the MIT researchers that worked on gyroid structures, I think they used SLA


  4. Hi Matts, thanks for the video. I would like to know after slice and infill the model in Slic3r, can we export the infill model into new STL file. I try export in Slic3r, but it gives me the original model every time. Thank you very much Jonathan


    1. Hi Jonathan, unfortunately it’s not possible to export gcode in STL form in slic3r, so you’re not going to be able to export the gyroid pattern. If you’d like to create a file with this pattern then I would suggest looking into MATLAB


  5. awesome! Looking forward to the video about how you sliced and prepared the vase. I need to graduate beyond PrusaControl, and slic3r PE will be my choice
