Every product goes through an iteration cycle before it reaches users:

Design → Test → Feedback → Refine → Finalize

In 3D printing, this cycle ensures that your digital model not only looks great but also prints successfully and functions well.

For example:

• A phone stand might look good digitally but could tip over if its base is too thin.

• A pen holder might have sharp corners or walls too thin to print properly.

Through iteration, you catch and correct such issues.
