Frostruder

Hi, I'm very near finishing my Reprap and am going to use the frostruder as my support extruder. I know all the kinks haven't been worked out yet but that's beside the point. I was wondering if it would be hazerdous to your health to consume the frosting that has been printed? It's going through another extruder so the only problem would be its contact with the deposited ABS. Opinions please? Thanks

Hi Matt,

cold ABS isn't toxic ... most plastics aren't ...

When you wan't even safer handling, use best stainless steel or POM for food-safe ambient. Next are other plastics without additives, then Aluminium - don't use Copper, Brass or such ...

Hi carpenma,

Did you ever get the frostruder working on your reprap? I am just finishing a reprap mendel now and am interested in soon upgrading it to also have frostrusion capabilities but it looks like reprap frostrusion isn't as far along as makerbot or fab@home... I saw the RJ frostruder design but that still seems quite preliminary.

I understand the draw of wanting to have everything reprappable, but at least for my first extruder I don't care if it's made up entirely of vitamins. Therefore do you recommend makerbot's frostruder or fab@home's frostruder as a starting point for me to get a frostruder working on my mendel?

Thanks,

theres a printable frostruder: the pfiercestruder, I think its called, up on thingiverse.

Thanks hintss,

How do you adapt a Makerbot Frostruder to fit a reprap? Is there some standard way?

the frostruders, IIRC, connect the same way all the makerbot extruders do: the 2 things sticking out to the sides, connecting to the Z stage. you could probably get the hole positions from the lasercut files for a makerbot.

and, if you check on thingiverse, i don't have a printer
