Soooooo... is there a way to get it to lay down solder paste??? :D

This is also good for dispersing glue, for glued SMD components. I remember time all SMD components where glued and wave soldered together with THT components. (Ugly memory of SABA TV chasis going trough head). Thanks for nice videos, and for hard work. Best Regards.

Great experiment but honestly I'm surprised this machine was not already being marketed for solder paste, adhesive, *ink*, etc.

:O looking at you extruder now i can use it as inspiration to fix my clay extruder , amazing work!, in another note probably you want to add a flat bearing to the gear so you can remove the play and wear.

Very interesting video ! Extremely impatient to hear about results for the UV resin idea (instead of carbon, couldn't you put some fine ITO powder or something inside ?), and super hyped about testing that system with common solder paste, this will be transformative (stencils are a pain sometimes) !

Doing this with solder paste instead of ink would make PCB assembly so much faster, and less manual. Then include a hot plate as well and boom, soldered PCBs without lifting a finger. Prototyping dream

There's a manufacturing technique called wave soldering where a board is basically dragged across a pool of liquid solder. This works well with through hole components that are all on the same side. However this process can easily be adapted to SMD components by adding a drop of adhesive between the pads of an SMD component. Often it's two tiny drops along the nonconductive edges of the SMD component. Many power boards are made this way where all the through hole components are on one side and all the solder joints and SMD components are on the other side. Anyway, this syringe setup is perfect for this process; it could add the adhesive, then place the components in the adhesive, and then the board would be ready to solder.

you could even put a blank pcb plate in, and cnc/laser the lines out. yep one layer. or multiple layers. not trying to pick on you, but.. you only have to do the alignment calibration once. before the jobs. how about silver instead of graphite. yep you can 3d print multi-layer pcbs. well laser the copper traces in between layers.

Carbon is too good at absorbing a broad spectrum. Commercial solutions use silver a lot so maybe that's a better option as it might reflect the light deeper into the blob. Loctite has a hole range of conductive silver inks like LOCTITE® ECI 1006 E&C

It won't be a surprise but it was quite predictable that the first drops of conductive ink woulnd't go onto the board, it is quite clear that you left a lot of play on the gear connected to the threaded rod, you can see it from the video, you can predict it if you know how you're doing this, you could close the gap a bit, use different materials to avoid friction, or even add a spring probably.
Also if you wanna play around with UV resin you might find some helpfull stuff in proper printing's attempts at an FDM resin printer, it's not the same thing but he was indeed extruding resin with a syringe, you might find helpfull stuff there.
That said I see many people suggest an entirely different route in any case good luck with that!

i hope it gets an experimental option so we can all use it, would make prototyping so much faster and easier, cause then you can say goodbye to hot plates or baking, and get the prototypes made and tested way faster.

Surely there is some clear conductive material from the touch screen or heated glass industry that could be mixed into yhe UV resin rather than the lamp black?
Actually what about chatting to the Positron 3D printer folks, their heated bed is clear!

I'm so excited to see it going with solder paste... you could have a reflow plate on the Lumen bed so it automatically reflows after... then maybe even a flying test probe to test the board once soldered, all in the one fixture!!!

Algorithm boy here. You could also make a little shape pattern on the back with multiple settings (back and forth on the serynge or air with different pressure). You can calibrate it quickly with it if you have the good tips (in your case, you're the first...).
Python function could generate gcode like for 3d printers pattern and z axis alignement. You can calibrate a lot !

Try adding 12hr setting resin as well as the uv. So that you get a skin set which holds the part with UV then the 12hr setting resing hardens the insides and sets the rest.

First of all, what weird stuff?

If you want your resin to cure, I would suggest to not use carbon... with something reflective like silver maybe even copper you might have a chance. Look into transparent conducting films if it fails.

There is a paper called "Photo curable resin for 3D printed conductive structures" in the Additive Manufacturing journal. "In this study, researchers used acrylic as the photocurable resin, AgCu flakes, and Ag NP for the metal fillers. They prepared the mixed resin solution/paste by adding 15 wt% of ethylene glycol, 7.428 g of AgCu flakes, 5 wt% single-walled CNTs, and 8 mg of photo-initiator Irgacure-819 into 80 wt% of commercial acrylic resin followed by ultrasonication and magnetic stirring for an hour."

Not sure if these are feasible on your time scale but what you are trying is definitely possible.
