PLEASE RESPECT THE LICENSE AND GIVE CREDIT TO THE CREATIVE MIND BEHIND THIS INNOVATION Got the idea for this from various 3D printed prosthetic hands and wondered how my conductive and flexible PI-ETPU 95-250 Carbon Black filament could bring a new dimension to it... This dualstrusion design will create the finished finger with joints and a force sensitive fingertip. The fingertip has an outer shell that, when pressed, connects to the inner conductive surface, creating a closed circuit. This model is only a quick proof of principle design... and the picture of a full hand is just a visualization of a hand that could be printed in one go... maybe? The smudging of the conductive material resulted in an open loop at approximately 8.5 kilohms and when pressing the tip it goes down to 7.2 kilohms It's my first dualstrusion attempt, I used 0.7mm nozzles and could certainly use to adjust the height of the nozzles and it would be fantastic to have retractable nozzles to eliminate the smudging... I designed the finger in a straight shape but it would be better to print it bent outwards, the TPU material has trouble bending the finger all the way back after it's been closed many times... or modify the shape of the joints... 3D printed with ABS and PI-ETPU 95-250 Carbon Black filament. PI-ETPU 95-250 Carbon Black is a professional 3D printer UV-stable, flexible and conductive filament that gets the job done. Don't need conductivity? Well, conductivity is great for some things but may not be your first choice. Then consider this: This filament offers several benefits if you don't require conductivity: •The material composition eliminates "stringing / webbing" issues. •The hardness of 95 shore A and the carbon black filler make for great print capabilities. •The carbon black filler is an excellent UV stabilizer, making prints built to last in very harsh environments. •The matte black surface finish has a unique look. •The material feels nice and dry to touch. •It's not too stretchy and will work well for timing belts, etc. http://rubber3dprinting.com/http://www.palmiga.com Follow on Instagram and Twitter:http://instagram.com/rubber3dprintinghttps://twitter.com/rubber3dprint http://youtu.be/5Bmg8tpI6Lkhttp://youtu.be/_7pgMqtvkughttps://www.youtube.com/watch?v=O9NCSGdXK8U
