Design the future with additive manufacturing.

Software built on transformative technology

Design technology that will not break.

Remove design limitations and overcome fundamental challenges with our unique modeling engine.

Your data goes in; optimized designs come out.

Feed your design workflows with real-world data, physics, and logic to harness the power of implicit modeling.

Build processes, not just parts.

Create reusable workflows and algorithmic processes that save you time and empower your team to scale.

Solve your toughest design challenges.

Aerospace and defense

Develop lighter, better-performing, more innovative parts that take full advantage of additive manufacturing.

Every single pound of material you can remove from a spacecraft saves money on launch costs. That’s why we used nTop to optimize the design.

Medical devices

Transform the standard of care by minimizing design time, automating validated workflows, and improving ergonomics.

This product has been hugely successful for us, and this is definitely in part due to the lattice structure that was created by nTop.

Consumer products

Get to market fast with head-turning 3D-printed products and define the cutting edge without the tedious manual work.

I have a general technical background, but I had zero CAD experience before starting Impact Footwear. We needed a solution that was user-friendly and [that] a 3D design novice like me could use. nTop definitely met this requirement.
