Cutting stencils
« on: July 28, 2016, 05:20:58 PM »
Im looking at a small 2500mw laser. I need to cut some stencils. I planed to use paper with sticky on the back.

I have never had a laser engraver and do not know if its possible. The smallest Font I need is 14 but mostly for symbols. This is an example.
Can anyone help?

Welcome Larry.

I would suggest a knife cutter (plotter) for cutting vinyl, as it produces very toxic vapors with a laser.

The US Cutter brand is an excellent choice for value.

Cutting paper, card or engraving wood are perfect for the laser and you can probably buy laser safe materials if you prefer the laser approach.

Do you mean a hand knife?  I cant find a knife cutter plotter. I have to cut out some letters size 14 type face. I know there to small to cut by hand. I do not want to stick them on I want to make a stencil so I can paint the symbols. I have some paper labels with a backing that I could peal off and stick to the metal and paint the cut out symbols. I also wont use it that much.

I was looking at the Silhouette Portrait which is around $150. It looks similar, reading how small of fonts it will cut. The Bell Fruit looks to be about 14 size. I have to cut out the letters so to paint.

If your stencil material is paper based or "laser safe" then a laser would work great, you will get much better detail from in compared to a vinyl cutter. Just make sure you avoid any vinyl based products on the laser.

I was suggesting the US Cutter machines http://www.uscutter.com/Vinyl-Cutters as they are great value.

If I were doing this type of job, I would probably take the plexi and spray the back with black paint and then laser the symbols / text (which would remove the paint) and then color fill with acrylic to produce the final result. No stencils.

I was thinking using shelf paper. Don't know if it has enough vinyl to be toxic?

These characters have to be put on a brass curved piece of metal.

Oh, well that changes things  :D

It looked like backlit plexi and I've done those overlays in the past using the method I described but obviously here the goal is different.

A mask / stencil sounds like a good option, and since they are small and detailed a laser would work very well if you select the right material. Use a non-vinyl material, such as a polyester (sometimes confusingly called polyester "vinyl" but it isn't a PVC material and much safer). Laser cutting most plastics releases toxic gases, some worse than others so venting or filtering is highly recommended.

I'm sorry to interject, but every time you guys start talking about toxic gases, I cant help but think of this guy........the huffer. 
I just chuckle at the possibility that there is one guy that probably likes the smells associated with lasing plastic materials.

I found this laser and they say it will cut a letter as small as 2mm Although I do not know if I believe that.
