A top notch prersentation and build. Even though I will never use any of this, I love watching for the heck of it!! Very well done.

I've seen a few attempts at using cnc to expose boards, most were pretty bad and others quite expensive to build. Yours is impressive, simple and has decent resolution especially for basic through hole boards. May take a crack at building a dedicated one, have lots of extrusion and printer parts laying around. Thanks for sharing !

im never going to try this but this is super cool, so cool to see people make custom things that work on 3d printers. Great work :)

I have three CNC machines, and a 3D printer... did I ever think of using it to expose photosensitive film? NOPE! Great job! Thank you for many new ideas!

Theoretically: yes Practical: no The spot size is highly dependent on the lens-object distance. The diaphragm of the lens greatly reduces the amount of light. It requires an expensive lens system. And a greater distance from the light source results in wavy lines when the machine vibrates.

I agree, many high quality sony UV laser diodes are cheap and simply use glass lens. Should be easy to build and provides a fine laser focus point. I have them sitting around, brand new many kinds of sony UV laser diodes and ender 3 V2. I never bothered to build the ender 3 v2 because I didn't expect it to provide decent PCB pitch lines. This youtube video shows it is very promising.

Not just any fiber though. Losses through conventional 62um or even 1.5um fiber would be too high and coupling light into those requires either precision optics or lasers. For UV, you need to use hollow core fiber that starts at 200um and about $40/ft, which is only about twice the resolution of this pinhole implementation. If you want to focus down to less than 200um, more optics will be needed at the other end too, at which point you may as well go with 400um hollow core to more easily pump more UV in.

This is a next-level project that you did... Hat's Off!

​@@warlockd I think you meant to write a message under the video and not under my comment, but I'll try to figure it out anyway. In the article "Transmission of UV Light with Optical Fiber" on the lasercomponents website there is a statement that a regular optical cable will not work, I quote: "In wavelengths shorter than 260 nm, UV light caused degradation in conventional fibers - a direct result of solarization effects." There is also a chart where you can see degradation of regular optical fiber cables. So basically you will need special optical fiber cable by Polymicro or other vendor in order to work for a long time or if you would use regular one then change it after half an hour of usage.

Your work is amazing, and I was really interested in your ideas, and how you made it. Although I think your mic setup is holding your channel back a lot, if you're wanting to do this for your videos to get popular- there was a lot of pops and background noise from your mic when you were speaking, that meant I had to dial in the audio just right to where I could hear it, but not louder, where it would start to hurt/chafe my ears. I think less background noise, a pop filter, or a better mic are all things that may make your videos significantly more enjoyable to watch. That being said, I'm really glad YT recommended you to me, I loved the video, and wish you luck in your projects!

Next, you'll be playing with micro-surgery soldering. Have fun. For normal drilling, the drill action is usually downward. I once have a DC motor drill for PCB, the drill is installed under a small 'table', the drill action is upward. To locate where to drill, there is a transparent acrylic glass secured about 7mm above the table, so the pcb can slide freely on the table. For the first time, the drill poke upward to make a small hole on acrylic. Then you can use this hole to guide the pcb at the spot right above the drill bit and press the motor upward to drill. Add a magnifying glass to help, to me it is easier than using a drill press to drill downward.

Excellent!

I had such project in mind however later gave up and just used SLA printer display for exposing photosensitive film on small (~10x15cm) boards.

I wonder if you couldn't just use the nozzle of the printer and drop the UV lamp down into the hot end... then you can expose it directly through a .2 or .4 nozzle, for example.

How is your Ender printer soo quiet?? Mine is loud as hell.

This is pretty neat. What about - instead of making a pinhole with an LED inside - mounting the LED somewhere out of the way and coupling it into a TOSLINK cable to not only position light output more precisely but also reduce the complexity of the setup?

Have you thought about a solution using a resin printer, finding a way to clamp the copper plate to the printer bed ? You might get a much greater resolution and precision

Very interesting 👍

I used UV laser instead. I was able to reliably get 0.25mm traces. I also tried adding a motor with a drill to make vias and mount holes. The only con with a laser is that it uses PWM driver and can’t be adjusted with input voltage (yet this is how most 3d printer controllers work - the gcode command adjusts voltage).

@nalinux

Жыл бұрын

PWM and voltage control are about the same thing, since the result of PWM is the average value. The main difference is heat dissipation in the controler.

Amazing

I tried do almost this. First I tried print plastic to the plate, but nothing succeeded. Then I tried attach pencil to hot end and thought printer can drawing it, but I'm used gcode for 3d model and printer didn't pull up printhead when changing positions. This solution is amazing. I will try to repeat this.

Thank you for the positive response. The pcb is exposed in 1 run. The amount of light on the film is determined by the intensity of the light source, the speed that it moves over the film and the size of the pinhole (0.1 0.2 0.3mm .. etc). So 3 parameters to control the exposure.

Hi! Why such difficulties, if there are cheap UV lasers. I expose photosensitive film and solder mask using these lasers.
