Polyester Impregnated Kraft Paper

How did you get it? Did you have to buy a big sheet from a distributor and pick it up yourself?

That is exactly what I did,

Hi Dave, I picked mine up at a local distributor. I got the .020 stuff and it was $9.00 per 4' by 8' sheet!! So I bought a few

Awesome models Ben.

What does the stuff cost approximately?

Also, what power and speed settings (for raster and vector) are you are using on it for a given thickness?

Thanks

Did you try oilboard?

I have tried oilboard and the results are not good compared to Polybak or lazerboard and the oilboard also oozes oil around the places you cut and makes it sticky, so if you raster it is messy and cant paint. Good for vector cutting large cuts.

Yes, I 10-4 that.

In case you didn't check the entire thread I'll post my source again as I have not experienced the problem you're having.

Look what turned up at our house today - almost 600kg of Polybak

Nice thread - very interesting evolution. I make pickguards from my dichroic laminate below, and often need a laserable backing to stiffen it up, so I just glue kraft paper to the back with epoxy, which soaks through the paper and impregs it well. I clamp it all up with release liner plastic, which ends up being the masking to eliminate soot off the back. I don't like Micarta or other common phenolic impregs as the laser has a real hard time cutting through the phenolic resin in the paper (called 060" brown backer through cabinet plywood suppliers). A true polyester impreg paper would laser much better, as I have made my own PE soaked paper, and it cuts well like my epoxy soaked paper. I assume thats what Polybak is.

Nice score of a lifetime supply.

Polybak is indeed polyester resin impregnated kraft paper. It is an industrial backer. I've bought 1000 sheets, partially for my own use, partially to sell in smaller sheets to hobby users who don't fancy meeting the 500 sheet MOQ per thickness. I love how it cuts and it's much cheaper than similar thickness plywood.

Video of the cutting of a small house I drew to test the material.

Fun!! Nice pinboard too. I made mine with a nail gun. Had to cut slots between the rows of nails for air draft, but my small parts always get sucked down into the Abyss, so the slots aren't the greatest idea. It appears you have mesh - good idea.

Nice ! What was your distribution contact ? In the U.S.?
And how many type of Polybak had you ordered? Between those types: PGB black, PB42, PB69, PB67, PB90,
Did you ever tried the Polybak Ultra at 0.035" thick?

Me, I have so much PB67, that I won't be ordering this type anytime soon.
