It's not entirely about density.... but over a very long period more dense particles will separate out, but for the duration of a print, they may remain in suspension. I've just realised that we could make 'prints' with any cheap resin of your choice and any filler of your choice. All you do, is buy the rubbery resin and print a mould. You could add 0.5mm to your design all round and knock out an open base design, then external to the printer, tip in any resin and filler of your choice. You cant do that with an extrusion printer. We should get the beta testers to try printing moulds. This would greatly extend Peachy's uses. The CAD software could have some code such as "print mould" which does all the necessary clearances for mould production. For small production runs, moulds would be amazing and there are very cheap catalytic resins out there.
