incredibly cool, excited to see what this will become in the future, also am curious about how you implemented the ink circulation, did you have access to the internal documents for the printhead?
Printing thinner layers might help cure more material in a better way, it seems like you have a problem with shrinking, but it's exagerated by the material not sticking to the previous later or something like that. When you tested the material the top layer of material shrunk, and the thin material that remained on the metal cured completely flat 1:40
maybe the uv light is curing it and burning it , like 3d printers where they dont fully cure the print , closed chamber with a pre heat might change results .
I feel like this could be more useful if you had it be FDM with inkjet at the same time. Maybe to seal up parts of the print to make them stronger, water tight, different colors, or just to put images under a layer of plastic. Have it lay down a layer of plastic, then a layer of resin, then layer of plastic and so on.
What material are you using? I know standard photosensitive resins don't cure very well in the presence of oxygen. Have you considered putting the UV light as close as possible to the printhead to minimize layer time and reduce the amount of time uncured resin has to shift around?
@@weirdtechresearch Oh ok that would explain the behavior of the material. Most resins for SLA 3d printing are designed to have minimal shrinkage when curing. I think normal uv ink probably doesn't have to deal with this unless you have a large amount of it. You could try normal SLA resins, but they have very high viscosity which is probably out of range of the xaar printhead unless you heat it to high temperature. I attempted something similar once with a modified epson ecotank printer and Siraya tech resin. I ended up clogging the printhead by accident and gave up on the project.
since you can do stuff, can you try levitate the liquid using ultrasonic inducers , and then cure that resin, but the key is to convert the shapes into sound waves or frequencys
@@weirdtechresearch thats where i had the idea from , there is onther video where a layer of sand will form a shape depending on the frequency and amplitud of the wave(or thats what i remmber) ,the idea is to suspend one layer at a time for it to be cured , i d ont know if it possible to convert a layer into sound , it would be amazing if the volume of the part is converted to sound where the liquid will take the shape and its just a matter of curing it .its possible i belive we just dont know how to .
