Wow, 3D #print your own #filament to create #multicolored #filament https://hackaday.com/2022/07/06/3d-print.. Insanely #creative !
Cool #idea to directly 3D #print onto a #tshirt - but as people point out in the #hackaday #comments - it would be far better to create a #stencil https://hackaday.com/2021/10/15/3d-print.. Still, I like the thinking and with the right #filament it really could have legs. Imagine one with a dye impregnated into it for example!
