Printing materials/binders

MasseyAlbany commented 9 years ago

Hi,

I have my PWDR printer running now but am struggling to get any parts out of it which seems to be an issue with the powder/binder combination. I am using a Nylon powder used in our SLS machine and it seems to be too fine to properly bind with the standard ink.

I was just wondering what materials and binders other people have had success with and where they were sourced. I'm specifically looking into ceramics now but want to try other media too.

Thanks.

SLS is a different system using heat to sinter the powder. PWDR uses a chemical binding process with a special powder/binder combination. See here:

You won't be able to print Nylon with the standard ink from the HP C6602 cartridges. But you can fill the cartridges up with aceton or similar (and aggressive) fluids. The C6602 is known to withstand it.

Please take a look at our paper on the Pwdr machine, which includes a section on producing ceramics parts: http://www.sciencedirect.com/science/article/pii/S2212827113001753
