Is 3d printing products allowed or it has to be handmade?

I wanted to get inspiration from those little models for coffee shops, etc but i dont know how they make it. I asked AI and it reccomended to buy wood slabs, use canva, glue and other equipment to make it but tbh alot of the stuff on etsy and on other platforms look like 3D printing. I really would love to try to do this but I need advice regarding this as I am new to this.

Thank you!
