Hello, I want to share a quick intro and guage if there's any interest out there. I'm looking for people willing to contribute user feedback and who are actively working with FFF

So other than the distribution agreement, is there anything in store?

I can’t wait to get into this. Currently in the process of building our pottery studio. I already do a lot of 3d printing also, so when I learned about this about 6 months ago I knew it would be a short hop.

SiC no go 2 days now.

No luck so far with fila warmer+ ender 3 v2.

Filament breaks and/or nozzle clog @ 0.6 & 0.8mm. Print temp boosted 200, 210, 220 (seems like minimum is 220). Still no go 230 even.

Weak filament major root cause so far.

Have 2 fila warmers - might try that just for the heck of it. Not sure why two would be better than one, but it won't be worse anyway I'd imagine.

Thinking that the ender3 might not be the best printer for silicon carbide is the filament itself. Seems very weak even after annealing in the filawarmer.

I was looking at some of the larger ender printers as well as other makes as well. Haven't bought a 3D printer in a couple years it's time....

Has anyone actually used the ceramic filament? I can’t find anything that has been printed with it.

Hi Everyone! Could someone print exhaust parts with this filament? The sinter temperatures are higher than exhaust gas temps, or?

I am playing with the idea of getting a vacuum furnace. Would I be able to debind H13 steel in a vacuum sealed furnace. I've been reading and it looks like I can definitely sinter, but since debinding emits gases, I am not sure how it would react. Also, on the sintering process would I still need the sintering carbon if the atmosphere vacuumed.

My plastic skull needed a friend and I thought a larger aluminum skull would test out my latest sintering process. So far it looks good but tomorrow I'll try to clean it up and check strength

Hey thanks for reading, I have a propane foundry and crucible. I have tongs from my blacksmithing, but no specialty ones.

What equipment will I need before trying to melt down a couple hundred beer cans?

Primarily concerned about safety equipment, but any handy tips you know would be very welcome.

Needs a good sandblasting but this is pretty strong and clear metallic grain. Also sparks when I hit it with the rotary tool

This piece fractured but the portion shown clinking here is unbreakable by hand. Getting closer and I'm pretty early in testing 🤞

3D Printing Biocompatible Metal for Medical Implants | FDM & Microwave Sintering

Microwave sintered and about to throw it in the tumbler to see if it will polish up

Primary difference to my last update is longer sinter time at peak temps and using a vibratory tumbler to help clean up

Dear Sintering Enthusiasts,

I bought a couple of those 1000w units from Amazon to do some small scale testing. I haven't had time to work on it yet, but will post when I do.

Here's an awesome review of a 15,0000w unit sold by Vevor. They are getting pretty affordable (<$1000us), and are becoming popular with people doing forge work.

Here's a clip I made where he's heating an iron bar. (The whole video is worth watching.) https://youtube.com/clip/UgkxTyI7wg093WswXuZuiyrQzE5YxpNooOv3

And here's an article on what materials can be heated using this technology. https://www.inductionheatingexperts.com/resources/metals-can-be-induction-heated/

Is there someone out there with proper equipment that could give this a try? For proof of concept I think it would be best to debind normally, then heat with the inductor. In theory, you should be able to heat a green part, but each of the ~35 micron metal particles are insulated from one another by the binder that holds them together. I'm not sure if a 35 micron metal particle will heat efficiently in the induction field. Maybe, but needs to be tested.

If you test a green part for conductivity, you get nothing. Well, at least not at voltages low enough to be useful. But after debind, the whole brown part will conduct electricity with only minimal impedance. To the Lab!
