Powder and inkjet printing
Hi all, I've been working with aengel on the Xaar system using kyle's code and we noticed that in his code after the power up sequence has finished, he has a delay put in for 1000 ms. Does anyone know if this delay can be shortened or even taken out completely or is it necessary to protect the Xaar head?
What cleaning agent did you use with the ultrasonic cleaner? Does IPA work?Wonko wrote: ↑Sun May 15, 2016 8:26 pm The nozzles were clogged from the solvent ink that I was using. I bought an ultrasonic cleaner yesterday which works miracles. I also ordered some UV curing ink from China to try exactly that. Next week's goal will be to mount the head in an XYZ-axis machine so I can print layers. UV ink s perfect for masking PCB's, and with XYZ-axes, etch-resist should be no problem.
The head is somewhat expensive at 200 Euros, but it is extremely versatile and does not heat up the fluid at all. I have pretty detailed descriptions on the Epson heads (also a Piezo head), which are starting at 100 Euros for 5 colors if you rip them out of a cheap printer, but controlling them is a few levels harder.
It's really great to see the HP progress. I'll keep you posted. Can't wait to get powder and jet 3D printing to work
