Hundreds of these needles will dance up and down in a rig, according to a pre-programmed valve system.
Doing this with 2mm dia. printed needles in a printed fixture and experimenting with many materials. It is required that they ‘slide’ within a 2.1mm shaft.
QUESTION: Has anyone had any success with any sort of lubricant for resin-on-resin bearing contacts? Silicone lubes make things sticky.
note: Currently only a white or grey resin has worked to hold the detail, grey pro of course at .025. But even using white at its max of .050 the detail is great. (Tried tough2000 a couple of times but it’s impossible to clean and dry and falls apart even at .050.). Form3B
Thank you in advance…
