I am trying to make a 3 d poster for my kid. I was thinking of using MDF but I hate working with it. It will be painted when its finished. I really don’t like the look of painted wood but it might be ok if I use plywood.

What other material could I use?

MDO, plywood with a smooth fiber covering that takes paint very well….it’s made for signs. If you don’t need that kind of durability, what about corrugated poster board?

Depends on the thickness of the layers. I really like working with masonite/tempered hardboard. Not quite as dusty as MDF. It usually comes in 1/8” and 1/4” and is available in the big box stores.

OK, I just learned something. In my reply above I referred to “corrugated poster board” which I just learned is actually a product called “Corroplast”. It has wider distribution than you would think, and can probably be found at the box stores as well as Walmart. It is a vinyl type material.

Coroplast is printed on with solvent inks, most common use is political and real estate signs. Most 3D signage is now made of a CNC’d foam but I don’t know the name of that product.

Sign·Foam is a good start is used a lot.
Precision board is HDU, high density urethane high density urethane is also recyclable if that matters.

On the more expensive side there is Ren Shape or OBOModulan is some of the easiest to machine and is used a lot for prototyping.
I have experimented OBO Modulan and like it but it is expensive.

On the Shopbot forum for sign making you will find a lot of HDU being used.

Thanks for the input. I think I will try the MDO but I don’t see it on Lowes or Homedopt web site. I have a few other lumber suppliers that I haven’t checked yet.

Once I get this done I will have to post it. My son is excited about it.

Have your say...
