The short version

  • Only Xometry has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Xometry xometry is the counterparty rather than the shop, and the margin between what you pay and what the maker receives is never disclosed, so buyers cannot benchmark the part price.
  • They diverge on capability: Simplify3D covers Process-based slicing, Xometry covers Instant Quoting Engine.
  • 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.

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.

Xometry

  • Xometry is the counterparty rather than the shop, and the margin between what you pay and what the maker receives is never disclosed, so buyers cannot benchmark the part price.
  • You usually do not choose or even know which supplier makes the part, so repeat orders can come from different shops with visibly different finish and process consistency.
  • For parts bought repeatedly over years the marketplace margin compounds, and qualifying a shop directly becomes materially cheaper.
  • Instant quotes are geometry-driven and degrade on unusual features, tight tolerances or complex assemblies, where a manual review changes the price after you have planned around the automated figure.
  • Because the software is free and the revenue is in orders, there is no software contract to hold the vendor to; support and continuity are governed by your value as a parts customer, not by a licence.

Answered from the vendors’ own pages

Simplify3D: Is Simplify3D a subscription?

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

Xometry: Does the Xometry software cost anything?

No. Quoting and Teamspace are free. Xometry earns on the parts you order, with the margin built into the part price.

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.

Xometry: Do I get to choose the shop?

Normally no. Xometry routes the job within its supplier network and remains your contracting party.

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.

Xometry: Is it cheaper than going direct to a machine shop?

For one-off and low-volume work usually yes, once you count sourcing time. For repeat production the marketplace margin makes a direct qualified supplier cheaper.

Simplify3D: Can I try it first?

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

Xometry: Can it handle ITAR or aerospace work?

It offers ITAR-registered and AS9100 routing on qualifying orders, but you must specify those requirements at quote time.
