Hi group.... I have gotten so much new info out of this group that I thought I would start another list of ways to use your laser for fun and profit. There was a list a while ago, but let's see how many we can come up with! (maybe the moderator can make a sticky out of it....

1. Applying hot stamp foil with the laser
2. Wooden and acrylic hands for clock movements
3. Edge lighted hallway and desk signs (use leds)
4. Door facings and inlays for front doors
5. Wooden "Tiffany" lamps
6. "Brick walls" (tiny ones for backgrounds on plaques)
7. Replacement or new "cathedral" radios (the scrollwork)
8. Stacked 1/16" acrylic sheets, each one lit by different color leds, with different artwork on each one, viewed from the front
9. Veneer with a layer of clear acrylic underneath, edge lit by leds. Makes the edges of the letters light up.
10. Springy things, made by cutting material into a spiral.
11. Old fashioned leather hinges, personalised and decorated, cut to size with holes for screws.
12. Leather handles for equipment.
13. Boxes with finger joints.
14. Working locomotive valve gear out of 1/8" veneers
15. Specialised presentation boxes for precision tools
16. Drilling templates for perpetual plaques
17. Electronic control panels reverse engraved on clear painted acrylic and edge lighted.
18. Custom buttons for sewing
19. Custom shaped business cards
20. Custom mount boards for photographs
21. "Art Deco" type bookends using wood and clear acrylic.
22. The humble label is often disregarded... the laser can make them and cut them out to any size or shape.
23. Labels for custom bottles printed and cut from foil.
24. Rubber, paper, and cork gaskets
25. Cloth items, especially synthetic fibers.
26. Personalised graphics for cars... the laser makes a pretty good cutter of mylar film.
27. Printed circuit boards. Laser away a resist, then etch with ferric chloride. Works well for name plates also. Thin metal parts can be made with this technique also. 2 sided etching requires good registration.
28. Sandblast resist. This has been covered a lot of times, but the applications are enormous. Most materials can be sandblasted one way or another. Most people are amazed at what a ceramic coffee cup looks like sand blasted 1/8" deep.

Lots of these have been suggested before, but the beginners are always asking. There is a ton of stuff out there for holiday decorations, so I didn't try to list them.

You missed a few of them that we have mentioned before like the food
and plants.

I actually lasered designs on some sugar cookies for Christmas (that my daughter made) including a photo of my son. People were afraid to eat them thinking that it somehow might have poisoned them or something.

So I ate them all myself (still here to tell the story). Also did a design on card stock and laid it over a sweet potato pie that I made, and sprinkled powdered sugar from a sifter, worked great. Anyone watch the "Ace of Cakes" show on the food network? How about cutting designs out of different colors of fondant to decorate cakes. Someday I may have tome to try it.

Someone told me that they lasered steaks in an upscale restaurant... don't know if it is true!

There is a company close to where I live who uses a laser to put their logo on the steak

I would think that doing that with a flatbed laser would be rough on the optics (steam from lasering moist food could be a problem for the material lenses are made from). But I could see doing it with a laser that used galvo mirrors since the optics are a lot further away.

Thanks for your efforts.

Re #27 PCB etching and namplates - what did you use for resist such that the laser will ablate it away cleanly? I have found problems with residue when I tried this using paints and lacquers. How thick of metal did you etch through, and what materials have you used?

Re #1 - hot stamp - has anyone applied hot stamp foil with a laser? With conventional hot stamping you need a lot of pressure, not just heat, to make the transfer.

Mark,

There are some neat ideas, thanks for sharing.

I have been wanting to do more with LEDs in frames and bases but don't know where and what and how to do it. Do you have any place that has good info on LEDs?

Thanks,

Aleta

One of the first things I tried when I got my laser.. Unless there is a special trick involved, I can't get H.S. foil to transfer.. Even tried shooting though a piece of glass holding down the foil for good contact.. Figgured it would transfer like a sublimation dye..But Nope... I have engraved both polymer and silicone dies for my HotStamp press, but still find that overall, it's less time consuming and more cost efficient just to get a mag die etched and be done with it..

Hi... first, I laser it twice without moving it to remove residue. Almost anything works for a resist.... I have used thin vinyl (yes, I know about the chlorine), rattle can paint. One trick is to sandblast very lightly with airbrush sand (there are airbrushes designed to use fine sand, try

www.paascheairbrush.com (http://www.paascheairbrush.com)

for brushes and supplies.) The sandblasting will remove the leftover film, and provide a chemically clean surface to work with. I have only done pcb's and nameplates. Chemical milling involves etching both sides or pumped and sprayed etchant for deep etching, which bring you into whole new realms of difficulty.

The materials I use for nameplates are standard engravers brass from Johnson and others. I have used the existing coatings as a resist without problems. Obviously, you need to coat the back side.

You might try a resist that dries somewhat on the "rubbery" side, to allow for more vigorous sandblasting. Don't forget there are many types of "sand" up to and including silicon carbide. All have different effects. We have 3 sandblasters in our shop, all filled with different materials.

Aleta: Leds are everywhere, and the cost has dropped almost to nothing. The problem is powering them safely, and selling a product that is powered by something other than batteries. Some sources: the folks that sell supplies to the big sign mfrs sell strings of these leds. There are several trade magazines that cater to these companies. "Sign Builder" is one of them. You can find the leds themselves on Ebay. Also, google "led power supplies".

Mark,

Thanks for the ideas, I will go look at those and see what I can find. I have some frames and bases I would like to put the light source in. I just have looked at some and they have a board. I am not sure I want to try to do light boards. Light strips would be great.

Thanks

A friend of mine just forwarded these links to me with articles and videos of laptops, Ipods, etc being engraved.
