All questions and doubts about CERAMBOT can be raised here.

Can we get the clay from anywhere or only from you?

[Jony Liu]

You can buy the clay from anywhere and you can also buy the clay from CERAMBOT. However,  we think CERAMBOT clay powder program is easy to use.

Can you give details on the clay powder used? This way we're able to locally source a clay as close to what you're using as possible...

[Jony Liu]

You can buy clay at your local pottery studio.

[Jim M]

OK. I understand that.

Let's try this approach...

These are the clay powders I can purchase locally in Atlanta, GA, USA.

KT 1-4 Kentucky Clay

Goldart Fire Clay

Fire Clay, Harbinson Walker - AP Green

Fire Clay, Missouri Hawthorne Bond

Georgia Kaolin

Helmer Kaolin 

Calcined Kaolin

Cina Clay, English Grolleg 

Barnard Clay Substitute

Would you be able to ask your provider which of these are closest to what they supply you?

This way, if we're having trouble making objects, we'd be able to eliminate the clay we're using as a source of the problem.

Thanks,

Jim

Except Calcined Kaolin, you can try other clay. The type of clay is not very demanding, you can find a lot on Amazon. pottery clay.

Hi Jim,

First, I want to say I do not have my printer fully up and running, however, I am a potter and have a good grasp as to what might be required for the printer. 

As for your list, all of the "clays" are a dry powder form and are usually ingredients in a clay body. A clay body is what you want to print with so it can be fired in a kiln. Typically, you are able to get wet clay bodies in various firing temperatures. A lot of manufactured clay bodies will have some of the ingredients listed above. You could always mix your own clay body, but I'd recommend starting with manufactured clay bodies. 

Again, I do not have the printer up and running but based on what I've been seeing from others here is what I gathered:

• You want to use a smooth clay body or a clay body with a low grog or "filler" content (something with very high mesh size if you have grog or filler.) 
• I would look for a smooth stoneware, personally I will be trying out B-Mix from Laguna clay. I know out east Highwater clay is good manufacture and has several locations along the Southeast coast. They have several clay bodies that would probably work with a little bit of mixing with water (https://www.highwaterclays.com/index.cfm?fuseaction=category.display&category_ID=35) If you click each clay body you can see a brief description of what qualities it has, I've used the Buncombe White before and it has a very fine toothy-ness quality to it.  
• You should mix the clay with water or isopropyl alcohol (IPA - will evaporate quicker letting you print more/higher because the clay dries quicker)
• Mix the clay to a toothpaste-like consistency and fill the large tube. 
• Print

If you don't have much experience with this stuff you might consider reaching out to a community clay center or a local college to ask their ceramics dept if they have any pointers on where to purchase clay. I did a quick search online and noticed there is a center https://www.atlclayworks.org/classes you might send an email and see where they get their clay and what clay they use. You could possibly buy a 25lb bag of wet clay. If you decide you like the clay that was supplied you can look into who manufactures the clay and if you can buy the clay body in a powder form which would make mixing the clay to the right consistency much easier. Most clay suppliers do not carry the dry mix of a clay body, it's a special order. 

I hope this helps a bit more with your search for clay. 

Best,

Ben Roti

Ben, Thanks!

That's the sort of info I was hoping for.

I don't have it finished either, BTW. I need to finish the electronics.  Good luck with yours!

I've gotten some SIO2 clay, specifically the PRAI that comes premixed and ready to print, but you might have to add some water and mix it if your pump can't push it all the way through.

They make three different clays specifically for 3d printing.

Hi!

Cerambot Air:
the screw cap for Cerambot Air is a very loose fit on the tube, and when air pressure is applied the cap blows off.
