When Will nTopology IPO?

As software is taking over the world, why not consume 3D printing, too? That’s the thinking behind nTopology, the leader in design and engineering software for 3D printing. With today’s current market climate, an IPO or ever-popular SPAC listing could potentially be in the near future.

What Does nTopology Do?

nTopology is an engineering software company that allows engineers to consider design, simulation, and advanced manufacturing in one workflow. Founded by Bradley Rothenberg and Greg Schroy in 2015, the company also designs and manufactures 3D-printed parts and products.

nTopology helps engineers create lightweight and optimized parts with their functional requirements built right in. Its software, known as nTop, has also assisted with delivering stronger and lighter medical implants for patients in need and allows said engineers to create complex, high-performance products.

According to the company, the name “nTopology” has two different meanings. The first explains that it relates more to geometric modeling technology than to optimization; topology is the study of geometric properties and spatial relations unaffected by the continuous change of shape or size of figures.

“When starting nTop, we wanted to build an engineering system that removes all modeling bottlenecks: you can design what you want, when you want — thus, you are not limited in the shapes you can make, so the name ‘nTopology’ came from ‘any topology,'” the company said on its website.

Its second definition derives itself from comparing its modeling technology to Computer Aided Design (CAD) models.

“A traditional CAD model includes ‘topology’ items like edges and vertices. We use signed distance fields primarily instead of edges and vertices, so ‘nTopology’ also means ‘no topology.'”

In October, the company teamed up with Stress Managing Services and Origin to compete in the inaugural USAF Rapid Sustainment Office Advanced Manufacturing Olympics; this was a a free, virtual event that included technical challenged featuring additive manufacturing and reverse engineering. The team created a multi-material F-16 hydraulic tube clamp and took home first place out of nine teams.

Will nTopology IPO?

nTopology has not announced solid plans of going public, but the company remains focused in solidifying funding for its growth.

Last September, nTopology raised $40 million in its Series C funding round, pushing its total funding amount to $71 million. Insight Partners led the round and was backed by the company’s existing partners Root, Canaan, DCVC, and Haystack; Josh Fredberg, an operating partner with Insight Partners, also joined nTopology’s board of directors.

In addition to its funding round, nTopology announced a collaborative effort with Stratasys, a manufacturer of 3D printers and 3D production systems for office-based rapid prototyping and direct digital manufacturing solutions.

In a press release, the two companies announced that they will provide a series of accessible, customizable Design for Additive Manufacturing workflows for their users. The first planned workflow, the FDM Assembly Fixture Generator, will help improve efficiency and increase productivity on the factory floor and is now available via the nTop platform.
