Peachy Printer Resin Filler to help make resin last longer

[Feign]

Though it might be common sense already, it should be noted that if you sue a filler, be sure to use one that doesn't lower the buoyency of the resin and make it heavier than the saline. Adding metal powders to the mix might do just that.

It's such an interesting possibility (adding resins) that perhaps a more dense fluid (than saline) should be investigated..... not too serious a suggestion, but mercury is quite dense....

How about glaubers salts (more serious)?

I would have thought that any filler would have to be the same density as the resin. If the filler was more dense, wouldn't it just sink in the resin and you'd end up with no filler in the upper part of the print? None of the printers I've seen agitate the resin to keep particles suspended.

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.

If the mould idea is viable, wouldn't mind trying some of this :- http://www.ebay.co.uk/itm/7701011-1-...item2a348e18cf
