A 3D printer filament, different levels of squish

When you've been using a 3D printer for a little while, you start to get really curious about printing things that aren't just your standard hard plastic. There are many options, but the ones I find particularly fascinating are soft or flexible filaments.

TPU is usually what you hear of and softness is measured in 'shore rating'. Basically, the lower the number of a shore rating, the softer and more flexible it is. TPU may be better compared to rubber or tough foam.

In this video, Lost In Tech shows tests on a very interesting filament that is supposed to be variable in the shore harness. The hotter you print it, the softer it becomes. It's called Varioshore and according to the video it works pretty well.

An added benefit of this system is that the material can be stiffer as it enters the extruder, which should save a few headaches when it comes to printing, as many printers have to difficult to run flexible materials through the system.
