Hey ,

I have written a small essay on using Lazertran here http://clacktronics.co.uk/information/diy/lazertran

So I thought I would share the photos on electro-music as a sort of photo essay (full text on my site) . I am really pleased with the way it comes out and I am planning to use it on my eurorack when it comes (I bought some tip-top z-ears)

I am doing one on Press'n'peel today and I should be doing one about screen print soon which requires a bit more hardware! I also want to explore DIY etching (electro and acid) with that you can also use press n'peel or lazertran (supposedly) as the resist.

That's nice work Clack -

Do you have any problems drilling the panel after application of the material? I would be concerned about tearing it...

Thanks
Gary

Wow, Clack. Very nice. I have never been tempted to try lazertran...until now.

Cheers all, I saw someone saying it didn't work for them on SDIY and I decided to write it up as when you have it down .. it is quite easy to do.

Generally not, it goes hard and brittle so a drill bit cuts clean through it. If its not baked properly it will lift a bit. The swarf from cutting the metal can scrape the surface a bit so use a bit of oil on the drill bit to prevent this.

Why not drill and prep the panel first? Use the same artwork to centerpunch holes, drill, sand and have everything groovy before applying the decal. I do this for use with the inkjet printable adhesive sheets, but I have to admit the lazertran stuff you're showing looks very nice.

would be interesting to see if it works ok
if the holes were to be drilled first
also if it would work over a painted [high temp engine enamel or powder coat maybe ] surface.
All my panels are white have been doing dry decal so far and its a pain
looking forward to your screen print essay
always wondered about how difficult it would be.

Yeah, I'm looking forward to seeing someone else's results with silk screening. I've actually gone ahead and purchased the supplies (frame, photosensitive emulsion, hinged thingy for holding the frame, exposure lights, etc.), but I've yet to actually do anything with it. The only thing I really need is some appropriate ink. Most of the stuff I've seen around is for printing textiles, and you really need something more durable for panel duty.

I'm also wondering how well a screen would work for applying ink as a resist for etching boards. No reason you couldn't use the same technique for solder mask and legends on the board. Anyone gone this route?

hey tim for the silk screen legend at least for a while now i have been just printing it out on a bubblejet onto normal paper and sticking to the board with cct board laquer really fast really easy and so far works fine
just dont use a lazer printer to do it, the laquer makes the image run .
just spray a heavy coat on the board surface and lay the paper over the top, line it up and squeeze out any bubbles let dry and hey presto board legend , also you can do any colour you want.
ps also tried dry decal for this also good . a bit more work
but nicer colours and sticks better there is an example of that
on the sync for foniks clock board i did on page two.

Hey,

I have done this before - it works fine

either the lazertran will sag down through the hole or it will sit across it. If it sits across it you can just break it through.

It goes brittle so it will snap cleanly away from the hole edge.

I am building a simple bed so that you can raise the height of the screen.

Yes the bad thing is you have to use epoxy ink which is a chemical cure resin, this means it produces fumes and it has to be cleaned off with thinners not water.

There is also something called mercury gloss ink that doesn't seem to be chemical cure (but is still solvent based) but I went for the epoxy stuff as I know more about resins.

in the UK you can get it here

Your Wasp drive looks great - I'm sorely tempted.

I have white front panels +- currently acrylic. I'd love to know how this process works on anodized surfaces? Anyone try that yet?

I have a laser printer that is not on the list (http://lazertran.com/faqs/). I assume the fuser oil is important, but wanted to check and see if anyone had gotten by with a non-approved printer. I really was looking forward to using lazertran.
