(I would really like to get a Casein mix to work. Four / powdered sugar (did not curl, loose adhesion) Powdered sugar (seemed to dissolve more readily than most other powders) Corn starch (poor adhesion difficult to spread layers evenly) curled with multiple print passes per layer.) Water putty / Weldwood (did not curl with one print pass. Water Putty (slightly better than plaster of paris) Plaster of paris (multiple print passes increased adhesion, loose adhesion) Portland Cement / Powdered Sugar (did not curl, multiple print passes increased adhesion) I will try to make a list of things I have tried and summarize the results later.Įdited 1 time(s). The page I linked is not even mentioned/linked on his main page. I e-mailed him once and didn't get a response. If you are interested in this stuff here is a link to a guy who has a more elaborate setup. (my best results have been with a single print pass per powder layer.) Multiple passes of water gives mixed results depending on the powder. I have tried using multiple passed on each layer of powder to increase the water volume. It is actually amazing how far the HP print head will spray water. I get pretty good results with water in the HP. That gives me 8 individual piezo inkjet heads to experiment with.) I have two Epson C80's that I am sacrificing to the cause (that is two printers with four colors each. You are correct Epson printers do not get a new print head when the ink is replaced. I had looked at PVA powder previously and decided against spending the money on it because I read that it is not readily mixed with water at room temperature. The best results I have had so far is a 50% - 50% mix of Weldwood Plastic Resin Glue (which you linked above) and Durahm's Water Putty [ (this stuff is mostly plaster but it seems to work a little better than straight plaster of paris. I have tried a bunch of different powders. I am holding off on doing anything elaborate to get bigger print area until I am confident I can get the powder to hold together fairly well. The print head is ~1/8 inch wide so that is as wide as I can print without moving the powder. I made a small (flat) platform to place the powder on when I am printing. It is an old HP printer with the paper feeding mechanism ripped out.
