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.; Simplify3D every serious competitor is free, so the $199 has to be justified against Cura, PrusaSlicer, OrcaSlicer and Bambu Studio on support and consistency alone, not on capability.
  • They diverge on capability: Authentise covers Additive workflow automation, Simplify3D covers Process-based slicing.
  • 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.

Simplify3D

  • Every serious competitor is free, so the $199 has to be justified against Cura, PrusaSlicer, OrcaSlicer and Bambu Studio on support and consistency alone, not on capability.
  • Major version upgrades are chargeable, so the perpetual licence covers a version rather than the product and the cost recurs every few years anyway.
  • Development cadence is slower than the open source slicers, and features such as newer tree support algorithms and multi-material handling appear there first.
  • Printer profiles for very new machines lag behind the manufacturer's own bundled slicer, so buyers of a brand new printer may get better results from the free tool that shipped with it.
  • Standard licences require an internet connection to activate, and the offline option is a separate purchase negotiated with sales rather than a checkbox at checkout.

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.

Simplify3D: Is Simplify3D a subscription?

No. It is a one-time purchase of $199 per user, but upgrades to future major versions cost extra.

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.

Simplify3D: Why pay when PrusaSlicer and Cura are free?

For a mixed fleet you get one interface and one profile library across brands, plus a supplier to call. If you run one printer from one vendor, the free slicer is usually the better choice.

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.

Simplify3D: Can I install it on more than one computer?

A standard licence is per user with online activation. Teams needing shared or concurrent use buy floating licences, priced on request.

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.

Simplify3D: Can I try it first?

There is a two week money-back guarantee rather than a free trial download.
