- This for anyone who wants a UV light source for curing photopolymers - there are planty of uses for this from screen printing to stamp making and it is very easy and cheap to make - this unit cost me 20 pounds but i had a lot of the cable and board laying around but even if you don't it is going to cost you a lot less than buying a box of this type

I always learn watching you vids even in vids where I thought I wouldn't ..
Re applications and types of UV and that you could use them to look after lizards ..You are a wealth of information Rob !
cheers mate lol
Well done!
Perfect, this is exactly what I need as I have just bought myself a Liquid Resin 3D printer (Elegoo Mars to be exact) and I need an UV curing box that will work in the 405nm range and knowing that UVA is good for steralisiing will also help as I can multipurpose this box to keep my ferrets water supply clean thus saving me from constantly changing the water every day and I can now do a weekly change or even make a self filling system in case I have to go away for any extended time,
You are a very valuable wealth of knowledge.
cheers mate
Hii Robert Murray-smith,
that's what you made is just a normal florescent tube light.. why you said UV cure box ? i have got florescent tube as my room lighting ( i like white light).. can i also use it to cure photopolymer ?
truly

what is best wavelength for UV SPOT or UV GLUE?
i looking for UV light tube T5 8W 29.5cm to make resin polymer rubber stamp,Please, Do you know any online shop on amazon or any website?
I'm new to your channel. I must say, I am sorry I didn't see it before now. I looked through your playlists and I really like your whole philosophy and attitude toward sharing your ideas and learning. You are very inspiring.
Things I really like are for example, the way you reuse things like your magnetic stirrer which became a centrifuge which then became a spin coating machine. And yes, you do a lot with the builder board (is that the same thing as plaster board?).
I have a question about the builder board. Since you use so much of it, have you ever taught of using the power (calcium sulphate - I believe it is), as a water filter to filter out the chlorine in water? I'm not in any way a chemist, and wouldn't know the difference between a calcium and a sulphate but thanks to you, I'll be learning.
The reason I am asking is because the great USA have shower filters built with calcium sulphate tablets of sorts, that filter 80%+ of the chlorine (that's the claim). The problem is, our shower heads here in Europe (the electric kind with the long handles and the flexible hose). Don't hold these kinds of filters, and I would love to find a way to make one.
Here is a link (you can skip to 7mins 50 seconds in the video to get to the interesting part - while interesting most times in this particular video she's a bit blabbery :-). czcams.com/video/5GDb4nmK9kU/video.html
Would be cool not only to know how to make one such shower filter, but also how to make the tablets described (so the plaster doesn't clog up he shower). And perhaps even how to make a machine to make the tablets (which I assume to hold them together in hot water, they would have to be made with some fairly high pressure). How to do that cheaply, as I understand, such machines are quite expensive.
Also on this and other projects involving light, have you considered the possibility of using an old scanner and a driver for the lamp. Especially considering you may want to feed your paper through at a steady pace (or pass the light over at a stable surface at steady controlled pace). This way you may be able to control the light colour and intensity as well (but I am not entirely sure if scanners also do UV or IR light - would be curious to know). Also have you considered using LED's as a UV source - was there a reason you went with the normal bulbs over LED's?
Finally, for your hotwire cutter, consider putting a hinge between 2 pieces of builder board, and some hotwire along the hinge. This will allow you to bend Perspex into whatever shape you need for making boxes for projects for example. I got that idea from this link: czcams.com/video/wVEf7PfuKxo/video.html
Thanks for saying that - builder's board is a PVC coated foam core material used a lot by window fitters here in the UK - I'm afraid I don't know much about using plasterboard as a water filter I can't see why not and a few plastic plumbing fitting and some glue would soon knock up a cartridge that you could put inline with your supply to experiment with - let me know how you get on - cheers and thanks for the other suggestions
Thank you for the interesting video Robert; I am wondering however, from where can I get the G5 UV fluorescent tubes. I tried to search on Amazon, but failed.
One more thing, do you think that if we increase the number of lights, the curing time will be reduced?
the higher the intensity of UV i would think the shorter the cure time - i got my lamps from here lampsdirect.co.uk/
If you have a UV curable conductive ink, would it be possible to build your swag plate with more closely spaced lines by using a mask over top of the UV light like in circuit board applications? It would seem you could also only cure the flat plate region and wash off the ink in the stacked plate region. Just a thought. Keep up the good work!
good thought mate - I will give it a go - cheers for that
Robert Murray-Smith Thanks, I'd love to hear how it goes.
I will let you know
hi, i just want to ask if this can cure spot UV varnish too, im planning to print business cards with some selected areas in uv laminate, also, may i know if any uv varnish will do, im from philippines. thanks
alain de leon i would imagine so
Hey, Thanks. Can there be an easier explanation to this? I would say not at all. Smart, Quick and Cost effective. Thanks again.
glad you liked it mate - cheers
Very explicit Mr Murray :)
Definetly passes Napoleon's test !
Great ideea!
I got some of those uv battons to look for dodgy stuff ( used to own a security co.)
you could make your own sun bed lol
nah ... I tan too easily ... couple pf pictures with the flash on and I'm done :)
actudoran
lol
I am uploading a vid shortly on youtube
I just replicated the Karpen and am still getting the full picture here ... the numers are incredible ... and still on the up.
whom did you mention me to ? :)
actudoran
just watched your vid - i didn't mention you to anyone that i am aware of but a lot of people watch my channel and may well have just taken an interest in what you are up to
can this stuff cured the plastisol ink for silk screen?
i've never tried it but probably
is there any chances robert?
there's a chance - i just don't know as i have never done it
noted
On the local market and fancy fairs the people often sell second hand face tanners, which already have the tubes in there. I know some other people scavenge for those as well, as I heard that the light helps to dry the nail polish (women things, yeah I know). I assume those devices are okay as well?
apparently the nail polish setters don't work - i looked at the face tanning stuff but that was still 50 pounds and i am a cheap skate lol - anyway to be honest mate - i like making my own stuff and the final plus point is making a small one is the same as making a big one so you could up the wattage and tube size to whatever you want - anyway enough justifying myself lol
Robert Murray-Smith I am wondering if the face tanning thing is due to wattage or specific frequency of UV? reason I ask is because LED UV lights of up to 30 watts are pretty cheap from china, but they produce a narrow band of frequencies since they are LEDs, so knowing the right frequency for your rig I think would be essential, so you are getting the right UV frequency for the ink.

365nm is the curing wavelength for most uv printing inks mate - the lamp i made isn't particularly powerful but will do the job in time - but you make one thing and people moan it's dangerous make another and they complain it is too weak you can only do what you do - this lamp takes time to work but won't burn out your eyeballs lol - if someone wants it stronger put higher wattage lamps in
Thomas Anderson
another thing to bear in mind is this can be put together by anyone who can change a plug - you have a degree of familiarity with circuit building but no everyone does mate
Robert Murray-Smith
Yeah the time vs the hundreds in cost is a no brainer here LOL, as for the frequency I did a bit of searching once I saw the rest of the video (lol yeah sorry) and found that 315nm to 400nm is UVA so good to know that there is a specific frequency though, so I know what to search for :) (also still very interested in SLA 3D printing using such materials as UV cured or just plain photonically cured substances, using lasers for the curing per layer :)
I build flexo's SMILE!!!! ;)
you build them!! - very cool
Give me spec and I can engrave a ceramic roller to your ink specs. I can build a 24" x24" printer for about 10,000 us dollars.. That's 80% cheaper than purchasing one & cutom built to spacific needs. It.s important to match the engraving on ceramic roller to the ink. I have 5 of them in operation.
Oh yea that's an in closed edge doctor system as well.
Let me know if you want one built. :)
Peace Murf

i am tempted mate - but i am not a printer and when this project is finished i am not sure what i would do with it
