Why use nTop for product design?

nTop enables you to solve complex engineering problems for additive manufacturing.

Speed

Receive real-time feedback and 10x to 100x performance increases because complex modeling operations that take minutes in other software become instantaneous in nTop.

Complexity

Create intricate geometries that would be impossible in traditional CAD, and manage design complexity using math, data, and logic.

Reliability

Build reusable design processes that won't break even when their inputs change, and connect workflows to your existing engineering software stack.

Get your hands on the most powerful design software for additive manufacturing

nTop gives you access to a unique set of capabilities that allow you to transform the way you design, refine, and scale product development.

Design

Create unbreakable geometries with our implicit modeling engine. Since every solid body is described as a single mathematical equation, you can adjust and iterate on your designs instantly.

Optimize

Achieve better performance by using Field-Driven Design to optimize based on simulation, test, or analytical data. Take advantage of our best-in-class tools to shorten your design cycles.

Scale

Create reusable processes to automate repetitive design tasks, batch-process similar parts, and generate multiple design candidates during simulation-driven design.

Software built on transformative technology

Implicit Modeling

Design technology that will not break.

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

Field-Driven Design

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.

Design Process Automation

Build processes, not just parts.

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

Easy in. Easy out.

Seamlessly import and export data within your existing workflows.
