Polyester Impregnated Kraft Paper

I stock PB90 (0.024") and PB Ultra (0.035"). Purchased from Lenderink which is the distributor. There is a 500 sheet MOQ which is probably why it's not readily available on the hobby market. I sell a variety of materials in sheet sizes to suit various laser machine sizes.

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.

Normally I make a small line break on the circumference to retain the parts. I just forgot to to that on some of the parts

If I cut a lot of the same part then I often make dedicated nail beds so the laser beam will never hit an nail thus avoiding any reflection marks on the underside of the material being cut.

Hi Michael,
Do you have any testing done with the PB Ultra (0.035") ? How does it react? Is it hard to uncurl it ?
Thanks.

I just store it weighed down. That flattens it. You can also heat in the oven at 140C weighed down between a couple of sheets of glass then let it cool. It can be thermoset.

ok, thanks
