No, you can't. Not if you're making IKEA furniture that customers assemble themselves.
>I think you mean plywood, not particle board. Very different things. Particle board is crap.
No, it's not, if you're making inexpensive furniture that customers self-assemble. Good plywood is very expensive.
>I’ve built a lot of my own furniture with hardwoods and none of it has warped in a decade.
Great, let's see you make something that way that ships in a flat box, and which some idiot can put together with pictogram instructions using no tools except a screwdriver for turning cam-lock fasteners.
You've clearly never dealt with old furniture. Tables, chairs and beds used to be and some still are packaged and assembled in this manner. Granted they used threaded inserts instead of cam-lock stuff.
Plywood will be stronger, lighter, and deal better with humidity, it is "better" as material on pretty much every measure.
Good, cheap, fast: pick any two.
For the price, particle board is good.
Back in the 90s, I bought a solid wood bookshelf and a laminated pine strip coffee table from them. They were structurally sound and very durable. In fact, a couple of years ago, I repurposed the bookshelf to create a built-in.
So it's definitely do-able!
You can also construct with hardwoods in a way that prevents warping and cupping, like using rift sawn cuts and orthogonal grain joiniery. It’s not some secret, this is taught in woodworking 101.
