The short version

  • Each has a real cost: PrusaSlicer limited to slicing workflow only; no interactive 3D design capabilities; 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: PrusaSlicer covers Automatic supports, 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.

PrusaSlicer

  • Limited to slicing workflow only; no interactive 3D design capabilities
  • Designed for RepRap-based printers; compatibility with other printer architectures varies

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

PrusaSlicer: How much does PrusaSlicer cost?

PrusaSlicer is completely free and open-source software developed by Prusa Research.

Source
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.

Xometry: Do I get to choose the shop?

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

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.

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.
