Talking better than MDF?

Hi
I was thinking of making injunction molds, but it seems a lot goes into making such cabinets. 3d printers, cad, polymers, and what not.

So was thinking to build the cabinet with MDF. But since it is basically a type of wood, it will be subjected to scratches, damage, water-prone, etc.

So for DIY, what can be the other alternatives.

Else, even if wood is used, what methods can be used to make it atleast to a certain extent, impact and water resistant.
I have heard of Moisture resistant MDF. but i guess it is only good for sprinkles.

I also had this crazy idea, to cover the entire surface of wood with super glue. Will it do something?

Thanks.

Use marine ply or shuttering ply. MDF is rubbish and the dust is carcinogenic!

Read this in a website
It is much stronger than Commercial grade plywood because of the superior wood and glues used in its manufacture.

What kind of glues?

Default Spray on Polymers or Stranded Bamboo...

If you really want to go "Overkill"....!

Polyurethane Spray Coating | Products | PAR Group

Spray on Polymers are a great solution.
They allow you to use a cheap core material (not just MDF) and then apply a super durable and aesthetically pleasing finish.
The downside is the environmental cost....Its a very toxic process, OK for DIY but not commercially viable.
Also cost is pretty high.
The best solution is actually stranded ( not composite block board) Bamboo with a few coats of natural oil.
Its a beautiful finish, almost totally carbon neutral & environmentally sustainable. The Bamboo will survive hostile weather for many years...

Hope this helps
Derek.

I'm building a speaker using a section of 8" I.D. clay sewer pipe. (Without the flange) The pipe is 14" long and I used 2" to seal one end with Plaster of Paris. Makes for .35 Sq. Ft. of room to work with. Coat it with spray on truck bed liner and it will last forever..

What do you plan to do with your speakers...throw them out the back of a moving truck? I use a mix of high quality plywood (13 plys in 3/4" thickness) and hardwoods like maple, walnut, etc. Finished with polyurethane they are as durable as any other piece of furniture in my listening room.
