M3D tough 115 is a hard TPU with a shore hardness of 115A (As reported by M3D).  I don’t have a color comparison at this time because I’m not sure it’s fair to compare a TPU to the color of PLA. This material is great for an item you want to be very hard and very wear resistant. It prints very easy for a TPU. While my settings worked fine you could print faster. This material should work fine on a Bowden printer too. This material is not very flexible. Expect your parts to be stiff.

M3D or Micro3D has a very wide variety of filament types to meet any need. M3D sells spools by the length, however don't let that confuse you when buying. 250ft is about the same at 250g when comparison shopping. The other sizes are 500 and 1000ft. For a filament which you may not need to use a lot, these smaller rolls can save you money. M3D often has filaments listed out of stock and some filaments are not available in the larger, more economical, sizes. M3D does release MSDS sheets and detailed print settings for all their filaments. M3D also puts a 3 letter code on the filament rolls which allows rapid slicer settings if you own an M3D printer. M3D provided many samples to help this site grow.
