Translating your designs into physical objects takes more work and a broad skill set that requires a combination of math, programming, art or design, materials science, and mechanical engineering. 3-D printers create objects as thin as 16 microns with one layer of material deposited at a time. As a result, the printed materials will behave differently than if they were produced in a mold or carved out of a solid object.

If a picture is worth a thousand words, a model is worth a thousand pictures.
You’ve got thermal dynamics, fluid mechanics, and mechanicals, all coming together to build an object layer by layer.

3-D printing can help engineers rapidly test their designs and make adjustments, which could otherwise take months. Engineers need to stumble, recover quickly and go through iterations before they come up with designs that work optimally.

Physical objects can help get projects to the approval stage faster!

Engineers can also use 3-D printers to build parts that would otherwise be impossible or time-consuming to make.
