Polyester Impregnated Kraft Paper

[Robert Ray]

Yesterday I got a small sample 4" x 6" of the material, and I took it out to the backyard in direct sunlight, and it hit me.

I had done some experiments a few years ago with different papers, cardstocks, and parchments, and the results were very similar, but I used marine spar varnish then.

This stuff bends and breaks as though it was made out of...

#170 to #200 Lb bond "Index" or "Cover" paper, saturated with Flecto Varathane, then dried to form this hard polymerized material.

As it costs from Northeastern ,compared to making my own, the Northeastern material seems economical enough, because Index and Cover is fairly expensive paper.

Does it breaks like in this video at frame 2:32 ?

I am thinking if it has paper or cellulose material in it, it is not dense enough to raster details. Has anyone rastered details to see how it turns up.
I am waiting for mine to show up, thanks Davie.

No, its not that brittle, it behaves more like cardboard when its bent. The smooth outer layer tears but the interior layers stay together.

In my limited test, dunking it in water lets it bend 180 degrees without the outer layer tearing apart.

The non colored material in the beginning of the segment does look a lot like this stuff. If thats the same material, it might be dirt cheap as off cuts.

Hi Kim

Yes, it rasters fine! I only made some small markings (1/87 grave stones ) haven't tried rastering a large surface yet.

1. Anyone wants to show their rastered results with this material? Even small details would do.

2. I've received my one sheet sample from Northeastern, but it is badly scratched on one side, like strait knife marks, pretty deep too. there is one scratch at each 1mm of distance. Is it being sold like this?

Ben

[David Fairfield]

Hi Ben

Yup its all scratched on the one side of all of mine, looks like its from rollers in the mfg process. Most of my parts are one sided so its not an issue for me.

Thanks David for the information

Well here we are a year later!!

Has anyone found additional sources for the "lazerboard" type materials?

I am still using 1/64th Plywood, but would love to find a better material that accepts paint a bit better and does not curl as much.

Any new ideas out there, and how is the Lazerboard material holding up for everyone?

Did you try oilboard?

Hi Darryl
It is called Polybak in real life, I don't know who first started to call it lazerboard, but North eastern scalelumber was selling it at a %500 markup

Here's the source for it Polybak the site will give you links to were to buy it, I've converted all my kits into the stuff, at the scale I am working with, it is more forgiving with people that have bigger fingers

Thanks a lot Ben. I was sure that it must have been an industrial material of some sort.

I am looking at ths same issues as you with very small parts for models and such.

Cheers!

Hi Mike, sorry I missed you message. I have not tried oilboard, but if I remember, this is a much coarser fibre substrate.

I have found the material that Ben mentions, though I can only find the 0.020 material. The thinner 0.011 would be great to try.

I will report some samples back when I get to testing it.

Cheers!

I tried all their available thickness, and they work really great.
Corrugated roof (3D pattern & Painted green) & and floor (planks pattern engraved): = 0.010" thick
Wall and posts: = 0.015" Thick (Beige)
Underframe roof (Star frame) : = 0.023" Thick

Gazebo is Scale: 1/220 meaning 1-1/8" in diameter.
