never seen it that thick. seems like it'd be a bit heavy to transport & stack.
why not laminate it yourself?

do you need exposed edges?

you can also build it up

3/8" mdf
3/4" furring strips
3/8" mdf

i'm looking to route a surface, and thus would like a uniform material throughout the core. laminating is an option, but would still present a glue line....

the "topo" you get from lamination can be quite beautiful. i like routing thin ply for just that reason. might be worth trying to work within the limitations of the material rather than trying to find that rare material that meets your vision.

(sorry for the desk crit.)

I believe it exists. I 've seen it before. It's the real high quality stuff too. I renovated an office that belong to a Kitchen Designer and He made all kinds of built in stuff out of MDF and had counters that were a really thick MDF. It may have been laminated from two layers of 3/4" MDF. Do a search of MDF manuf. and call to see whats available.

i agree with others here...1-1/2" mdf is going to be really heavy..
as in not practical to work with heavy..but maybe you can find some
lightweight mdf..

imo..if done well the glue line really shouldn't show all that much..
if weighted properly it's going to be pretty minimal...

i also have a feeling that costs for that thickness would be pretty
prohibitive.. build up allows you to build it up in certain areas so
you don't have to spend as much time routing everything out.

it looks as though the thickest readily available is 1-1/4"
