Containers for Firing

[EdtheSinterer]

First let me say that I think this is truly an exciting product. The possibility of being able to print "metal" objects the same way (more or less) that we now print plastic is a game changer, as far as I'm concerned. A colleague has been experimenting with Filamet for a few weeks and seems to have the printing process pretty well dialed in. Now it's my turn to figure out the firing (sintering) process so we can truly make metal objects.

I don't see much on the website or this forum regarding the sintering process, but my intention is to share what we learn. Is there anything the VF guys can add at this point? I've watched the video, I see the firing instructions, but is that all there is right now? For example, this is from the Sintering Process Instructions, "....(see instructions for magic black powder)".

I have not been able to find these instructions anywhere, and none came with my shipment of MBP. Can you provide a link, or something?

Can you give some more hints about the containers that can/should be used for firing? Aluminum is obviously out of the questions, but are thin steel cans (e.g. soup cans) suitable? Do they need to be closed on the bottom? Should they be covered during firing? (the video shows some kind of cover).

Thanks, any additional hints or suggestions would be helpful.

glad you like the product, I have alot of fun working with it myself, for firing I use cut up tail pipe, you can find the magic black powder instructions in this group, for firing just following the instruction exactly, I recommend for your first time to print the swirl cone model which should be back linked on our website in a day or two, the sintering time can very by size, the 45 minute time is the correct amount of time for an item the size of a swirl cone

FWIW, soup cans are not suitable.  At the sintering temperature, they become so soft that you'll warp or puncture them with tongs!  Learned that the hard way when we were pulling it to quench...

Well ya, tin and aluminum have much lower melting temps than just coppers sintering temp you have to use a metal with a melting and sintering temp above copper, steel works great, happy firing!!!
