Yes - why did this topic grind to a halt?

Did it move to a different location?

(my interest is to be able to print out a mold I can pour hot copper into and an additive mold idea would work just as well
for my needs as doing a additive wax model to then be used as lost wax.)]]> mr Powder Printing and Selective Laser Sintering Mon, 31 Dec 2012 21:14:50 -0500 https://reprap.org/forum/read.php?153,11563,164172#msg-164172 Re: What Z-corp ink is made of https://reprap.org/forum/read.php?153,11563,164172#msg-164172 Sigma Projects Powder Printing and Selective Laser Sintering Sun, 04 Nov 2012 00:15:03 -0400 https://reprap.org/forum/read.php?153,11563,121301#msg-121301 Re: What Z-corp ink is made of https://reprap.org/forum/read.php?153,11563,121301#msg-121301 pete]]> docsavage777 Powder Printing and Selective Laser Sintering Tue, 28 Feb 2012 00:51:49 -0500 https://reprap.org/forum/read.php?153,11563,115187#msg-115187 Re: What Z-corp ink is made of https://reprap.org/forum/read.php?153,11563,115187#msg-115187

But I will tell you that we are currently working on
printing "fireable art ceramics". We are working on our
third type of ceramic and after it's characterised I will
be submitting journal articles.

Also, I have a group working on our second version of a
personal 3D printer (P3P).

We also have two fab@homes which we have done many student
projects including printing ceramics and glass!

I have been formulating Z-like powders/binders for years. I've
had several MS/Phd students work in this area. I would like to
share a quick and easy workable powder/binder system with this group.

Powder:

1000 parts by weight(PBW) Plaster of Paris
250 PBW extra-fine sugar (not powdered)
250 PBW maltodexin (use Bene-fiber if all else fails)

Binder:

1 parts by volume (PBV) 105 proof vodka
2 PBV distilled water
Food coloring to make your favorite color.

This is a solvent binder style system. Leave parts in powder bed
at least an hour, then bake 80 C (for 40 minutes). Post-process
with favorite compounds.

Perhaps we could encorporate this in a RepRap... an ink-cartridge toolhead. Then we would have:
- thermoplast extruder (additive)
- milling heads (subtractive)
- CMM-probe (3D top surface scanning)
- paste extruder (candy fabbing!)
- TBD: ink-cartridge toolhead (we'll need a rod to spread the powder too...)

here is a description of what the powder is made of.
It's just dental plaster ( Durone 4 Brand) + 30% of weight
maltodextrin( midway brand, guarana with acai flavor).
I did try some other flavors but it doesn't work well as this one.
I don't know why, maybe the guarana or acai helps on bonding.
I did try just maltodextrose but it won't work as good as the one
mentioned.
I'm using just destilated water on the printer cartridge.
the heater on the building chamber helps the water to dry out
faster,and stay on that layer only.Plus the models won't need to go to
the owen to dry out.It's made of a 40w soldering iron screwed to the
alluminum plate on the building bin.
I'll be posting more pictures of next week.

It looks like he is using Durone 4 Brand dental plaster and maltodextrin.

The Yahoo group is new. They are just getting started.

Looks like the place to be for 3D inkjet printing.

4 onces Terra Alba mixed into 50 pounds worth of ultracal 30 powder.

Add 2 onces of Aluminum Sulphate to the proper water volume needed for a 50 pound mix as well. Aluminum Sulphate works quicker than Potassium or Zinc sulphate.


The warmer the water mix is, the quicker the ultracal will set as well.

I think Zcorp is using starch, but then again. I don't see why this system won't work.

Paint the Ultracal with a Forton resin system to strengthen it.]]> makeit Powder Printing and Selective Laser Sintering Wed, 23 Jul 2008 12:41:46 -0400 https://reprap.org/forum/read.php?153,11563,14791#msg-14791 Re: What Z-corp ink is made of https://reprap.org/forum/read.php?153,11563,14791#msg-14791
The top layer could potentially contains some very fragile areas indeed... the beginnings of a part with a flat horizontal surface are going to be a single layer thick for example.

Unfortunately, you're also going to be wobbling your 'curing' parts, and also potentially misalign the bed for the next layer of printing. Then theres the problem of constantly shaking a cartesian bot made of cheap steel tubes not designed to withstand forces anywhere near that.

Its a good idea though.]]> proto Powder Printing and Selective Laser Sintering Tue, 22 Jul 2008 20:51:59 -0400 https://reprap.org/forum/read.php?153,11563,14755#msg-14755 Re: What Z-corp ink is made of https://reprap.org/forum/read.php?153,11563,14755#msg-14755 is that a good idea?
