Make a PCB with 3D printer, UV led and photosensitive film

Good stuff 👍🏼

Great keep it up ❤

very very compliment , all fantastic

genius.... brawo

8 thou track pitch isn't bad at all.

Fantástico

Interesting way to sensitize PCB photoresit, what kind of PCB trace resolution can be obtained? Good enough for QFN/FPGA circuits?

Это было бы интересней если делать детали из лака уф тогда бы был бы толк

Помоему проще фрезой Сразу сделать плату чем печатать и потом травить...😅

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?

I've been doing something similar using a resin 3D printer, much easier. Just create a single layer print with the reversed circuit design, and expose it for 40 odd seconds directly on the printer screen.

Гениальное просто

Interesting technology! Thank you!

¿Y usar laser de grabado? Con pintura de cualquier tipo sobre el cobre

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

Wow! That is an amazing system.

Man, you are the Bob Ross of Electronic.

Thank you so much! Shared in Hungary :)

Brilliant, just brilliant. I look forward to additional instructional videos.

Hello, your work is very nice ,I will do it when I have the opportunity and time :S .after getting out of jail XD ... I wanted to try to make eye lens for imaging by pressing a matrix on a transparent led surface like yours on a simple level.even pcb circuit, battery, mechanic, synthetic, texture, metal, plastic, wood :) was a nice .When you think about it, it is possible to print full brain tissue, even positronic brain XD there are a few more things i want to try.

How it would work with laser cutter?

nicely done Will, maybe an old mechanical watch movement can help you to make the orifice. I would use a jewel of it. vary of sizes are to find. balance axel is usually between 0.09 to 0.12mm, they are wear-resistant. Hence, this is how they made the pcb films long ago with the use of aperture wheels. If I find some time will make a similar device and upload a video of it. " just did a quick test, the red ruby doesn't filter the UV light"

how do I contact u?

With less effort could add spindle = turn into cnc and route board, no need for nasty chemicals and can drill holes with same machine :)

please upload more video about this

i am in

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.

Круто!

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.

Leuk project, goed werk!

what software do you used for desing pcb.

I wonder if you can use a scrap piece of fiber optics and glue it in the hole as a makeshift lens. I would hesitate to use single mode as its way to small, but maybe? I think you would have to polish the fiber each use though as it would scratch itself up. Humm, maybe it doesn't have to drag itself on the surface, as its small enough. Ugh to to play with this setup, digging out my old ender 3 now and my 20 year old splicing kit hah.

Woderful solution to make PCB boards on a 3d printer. Thanks
Does it make it in just one pass. Only controlling the time the led is lighting over a point?

Where you get the photosensitive film?

Formidable ! 👍

Amazing what people do with the humble Ender

I never seen Subscribe Number increasing , that much Fast 🎉🎉

I'm just wondering what the actual gain of this approach is. You still need to develop the UV-sensitive layer, so how is this better than printing out the mask on a laser-printer (on a transparent sheet) and using that to expose the UV-sensitive film? I would expect that the real gain would be to get rid of the exposing and subsequent etching/dissolving mess, no? Then again, I'm at the "soldering TH components on perf-board"-level, so all this is just way out of my league ...

Impressive project. Just one small criticism: please don't pronounce LED as "lead" ;)

I like this alternate usage very much, and believe that I will try it.

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).

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

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!

meglio usare un bromografo😊

Buen video, espero con ansias más videos así

I wonder if this can be done with some type of laser with very narrow beam... great project!
