3D printing is not as strong as injection molding the same material in the same shape.
But you can beef it up. You can 3D print stuff much bulkier than injection molding can do.
If you really want to, you can also use stronger materials.
Also, even the weakest cheapo stuff you can get is plenty strong for most stuff people are printing.
Knowing about what makes a part strong or weak helps a lot.

The durability comes with the design and the material used. As I said on another comment the first version was very fragile and was bending with barely any weight on it.
After adding a bracket to hold the glass in between it keeps its form even with food on top. It all depends on how you design the piece and in which direction you print. Not always the easiest way to print is the best for durability.
