The short version

  • Each has a real cost: Authentise nothing is published about price, and modular licensing means the quoted entry module rarely resembles the cost of a configuration that actually runs a production floor.; nTop nTop is a specialist tool that sits alongside mainstream CAD rather than replacing it, so you pay for an extra seat and accept a handoff between two geometry systems.
  • They diverge on capability: Authentise covers Additive workflow automation, nTop covers Implicit modelling.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Authentise

  • Nothing is published about price, and modular licensing means the quoted entry module rarely resembles the cost of a configuration that actually runs a production floor.
  • It is additive-specific, so a shop with significant machining, casting or fabrication work still needs a second MES and an integration between them.
  • The ITAR-capable deployment that justifies the price is irrelevant to purely commercial shops, which then find the system expensive relative to general manufacturing software.
  • Integrating with the ERP and PLM systems that already hold part and order data is project work, and the burden falls on a small vendor rather than a large systems integrator ecosystem.
  • Company scale is modest against the industrial software incumbents, which is a real consideration for a system sitting in the traceability path of qualified aerospace parts.

nTop

  • nTop is a specialist tool that sits alongside mainstream CAD rather than replacing it, so you pay for an extra seat and accept a handoff between two geometry systems.
  • Implicit modelling requires a different way of thinking from feature-based CAD, and the retraining period is long enough that unused licences are a common and expensive outcome.
  • No pricing is published and there is no free or hobbyist tier, so evaluation runs through a sales process and small teams cannot try it seriously without engaging.
  • Subscription only, with no perpetual licence, means the geometry logic you built stops being editable the day you stop paying, which is a real risk for long-lifecycle aerospace and medical programmes.
  • The output is most valuable when you have additive manufacturing capacity to make it; organisations without machines that can print the geometry end up designing parts nobody can produce.

Questions people ask

Is Authentise or nTop better?
Neither clearly leads. Authentise starts at On request and nTop at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Authentise or nTop?
Authentise starts at On request and nTop at On request.
Does Authentise or nTop run on more platforms?
Authentise runs on Web, API. nTop runs on Windows, Cloud.
What is Authentise best used for?
Authentise is most often used for an additive service bureau tracking jobs across a mixed fleet of printers from several vendors, an aerospace supplier that needs powder batch to part traceability as qualification evidence, a defence programme requiring export-controlled geometry handled under itar-compliant hosting, a corporate additive team standardising build preparation and post-processing steps across sites. Of those, an additive service bureau tracking jobs across a mixed fleet of printers from several vendors and an aerospace supplier that needs powder batch to part traceability as qualification evidence are not what nTop is typically brought in for.
What can Authentise do that nTop cannot?
Authentise covers Additive workflow automation, Machine data capture, Traceability, Modular deployment. nTop covers Implicit modelling, Lattice and cellular structures, Field-driven design, Integrated simulation.

Answered from the vendors’ own pages

Authentise: How is Authentise priced?

It is not published. Licensing is modular and quoted annually, with integration and onboarding priced separately.

nTop: Is nTop the same company as nTopology?

Yes. nTopology rebranded to nTop. The product is the same lineage.

Authentise: Can it handle ITAR-controlled work?

Yes. It offers ITAR-compliant deployment alongside public cloud and private SaaS, which is a primary reason defence suppliers choose it.

nTop: Does it replace SolidWorks or NX?

No. It is used alongside them. Mainstream CAD handles the conventional geometry and assembly; nTop handles the lattice, field-driven and complex internal structure work.

Authentise: Does it work with printers from more than one manufacturer?

Yes. It is designed for mixed fleets and captures machine data across vendors, which single-vendor software will not do.

nTop: Is there a free version?

No free commercial tier is published. Access runs through a demo and sales process, with academic programmes handled separately.

Authentise: Is it a full MES for a general machine shop?

No. It is built around additive workflows; subtractive-heavy shops need a general MES as well.

nTop: Can I buy a perpetual licence?

No. It is sold as an annual subscription, so budget it as recurring cost across the life of the programme.
