The short version

  • Each has a real cost: OpenSCAD script-based workflow, not interactive design interface; 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: OpenSCAD covers Script-based modeling, Xometry covers Instant Quoting Engine.
  • Prices and features above were last checked on 31 August 2026.

Xometry

  • An engineering team needing machined prototypes in a week without qualifying a shopnot OpenSCAD
  • A procurement group consolidating dozens of low-value part suppliers onto one purchase ordernot OpenSCAD

  • A design team price-checking a geometry change before committing to itnot OpenSCAD

Where each one falls short

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

OpenSCAD

  • Script-based workflow, not interactive design interface
  • Limited to constructive solid geometry and 2D extrusion modelling
  • Not suitable for artistic 3D modelling or computer animation
  • Complex build dependencies (Qt, CGAL, Boost)

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

OpenSCAD: What is the cost of OpenSCAD?

OpenSCAD is free software with no licensing fees, subscriptions, or costs of any kind. The software is available as open-source with no restrictions on commercial or non-commercial use.

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.
