LED UV Lamp Retrofit On CET X-Press FK-512X, and some...

[THIS THREAD IS OPEN FOR ALL DISCUSSION AND BRAINSTORMING]

This is something I am seriously researching. #artbot...You may want to look into this as well. I want to custom cut a reflective half inch thick clear plexiglass back laminated with a chrome film. I will have holes drilled to fit in the LEDs on the face (lit) side I will have little diamonds or half spheres milled out to disperse the light and have it fit directly into the 3.25x5.25 window on the lamp shrouds. To power them on and off as the shutters do, I will wire them into the shutter signal.

Granted this will be a test, the things I need to know are the following:

- What is the optimal light output I need to properly cure the ink. (How many LEDs and what size/output?)
- How much voltage does the shutter signal output and how much can it handle?

I have had too much trouble with material expanding and becoming waste due to head strikes and risking thousands of dollars in heads. Plus replacing bulbs every quarter or so is super expensive, not to mention use a missive amount of energy.

I feel as though that this conversion could really pay itself off in less than a year and provide much better results.

Lets have fun with this and make something happen!

it'd be great if the existing power supply would work for a new lamp system. then as well the light would have to be the same. it seems that the ink would be formulated for a very
specific wavelength.

here are some curing units off of alibaba that might do the trick for a real system.
keep in mind that mimaki eventually installed a gantry wide post curing lamp because they couldn't get the juice to the ink with the led lamps.

i'd try to find someone locally that has an led curing unit (high powered). print something with the lamps off then pass it under that unit quickly. that would be a real time true test
of it's viability.

i purchased a small enexpensive led uv way back to test for curing and i found that a fluorescent black light put out more joules than the "uv curing LED". the type that is
needed for curing will be a pretty beefy lamp with a power supply.

when i got back to the seller (uvprocess) they explained that i needed a high powered unit.

you could probably send them an uncured print to test.
