Thus 0.4mm X 25.4
for the diameter of the nozzle was the design goal.

Smearing ABS cement on the hot bed is not the same as solvent welding because the the solvated acetone is bonding to glass, aluminum or so other non reactive surface. Then after the ABS cement has dried, 3D printed parts can fused to the initial layer of ABS thermally.

If you need a 25.4X flow rate, wouldn’t you need the cross-sectional surface area to be 25.4X as big?

.3mm nozzle = Pi *.3^2 = .2826 sq mm
25.4* (.2826) = 7.17 = Pi * (1.5)^2, or the new nozzle would be 1.5mm diameter.

That’s definitely big, but not on the same order as an AK round :)

The group with the 3D printed canoe made from recyled milk jugs seems to be heading that direction with their extruder setup:

I wish I could give it a try, it seems to be much better and more precise than the doodler. Fascinating concept.

i own a Zprinter 150

so i find they overcharged the powder, binder etc.

finely i find someone who suggested to use distilled water with a drop 1.5 or 2 dish washing soap, mix this up with 1.5 liters of the distilled water and then injected into the cartridge trough the nozzle with a big syringe, anyone experience with this?
I am still under warranty so i decide to do some research before i experiment!

any suggestions are welcome.

thanks!

However, different glass bottles have different coefficients of thermal expansion which might make them incompatible with one another and cause cracking. You will need to do some testing.
