Looking for soft flex filament
I'm trying to print a plug that goes in the back of a replaceable ink cartridge for an Epson 3880 printer. I have some Matterhackers FLEX filament which I've used for other things, so I printed one using that. Unfortunately, the material is a little too stiff to seal well, at least for a cartridge with PiezoFlush in it. Does anyone have suggestions for a soft, silicone-like filament?
Not one printable on a Mk3 ... but you have another option.
Use the part file you have as a negative to make a mould:
Design a block, perhaps in two parts, and subtract (difference) your part from the block to make a void into which you can pour two-part or low temperature setting silicone of the desired softness. You may need to tweak tolerances to account for thermal contraction as the part cools and you may need a coat of separator to prevent the part sticking to the mould.
Cheerio,
