Aspire vs VCarve vs Carveco vs Fusion 360: Which CAM Software for STL Carving in 2026

Which CAM software should you buy for carving bas-relief STL files? The internet will tell you "Aspire is the standard." The internet is right about half the time. Here's the practical version, written by a studio that ships STLs to thousands of carvers across all four packages.

This isn't a feature-checklist comparison. It's a working maker's view of where each package earns its money — and where you'd be smarter spending less.

The TL;DR

• Vectric Aspire — the de facto standard for bas-relief work. Best STL preview and toolpath generation. Expensive (~$2,000). Buy if you carve bas-relief weekly.
• Vectric VCarve Pro — Aspire's smaller sibling, ~$700. Handles STLs perfectly fine for finishing toolpaths but lacks the modelling features. Buy if you're a buyer-and-carver, not a modeller-and-carver.
• Carveco Maker / Maker Plus — subscription ($15/mo Maker, $45/mo Maker Plus). Strong feature parity with Aspire's modelling tools at the Plus tier. Best for hobbyists who want pro features without a $2k up-front hit.
• Fusion 360 (free for personal use) — the technically-strongest STL handler of the four, but the bas-relief workflow is unnatural. Use it if you already know Fusion or need parametric mechanical work alongside carving.

The rest of this post explains why.

What "good at STLs" actually means

A CAM package handles a bas-relief STL well when it does three things:

1. Imports without choking. A 150,000-poly mesh shouldn't grind the app to 0.5 fps.
2. Generates clean finishing toolpaths. Tapered-ball, scallop-tracking, contour finishing — these should be one-click operations with sane defaults.
3. Previews the result honestly. If the preview looks crisp but the carve looks flat, the software lied to you. The good ones don't.

Every package below clears bar #1 in 2026. The differences are mostly in #2 and #3 — and in how much time you spend fighting the UI to get there.

Vectric Aspire

Cost: ~$2,000 one-time, plus optional upgrade plan (~$400/year).
Platform: Windows (Mac via Parallels works fine).
Free trial: 30 days, full-featured.

Aspire is the package most professional bas-relief carvers settle on after trying everything else. The reason isn't that it does any one thing dramatically better — it's that the workflow from "drop in an STL" to "post G-code" is shorter than any other tool, and the modelling features for creating your own reliefs from photographs are best-in-class.

For finishing bas-relief toolpaths specifically, Aspire's "3D Finishing" with a tapered ball produces results indistinguishable from Carveco at the same settings. So if you're a buyer who never plans to model your own relief, you're paying $1,400 over VCarve Pro for the modelling tools, the 3D component library, and slightly faster preview. Worth it if you carve weekly; overkill if you carve monthly.

Best for: Anyone who carves bas-relief as a steady part of their work, especially if you'll occasionally model your own from a photo.

Vectric VCarve Pro

Cost: ~$700 one-time.
Platform: Windows.
Free trial: 30 days.

VCarve Pro is the package most makers should actually buy. It handles imported STLs identically to Aspire — same toolpaths, same preview, same G-code output. What it can't do is create or sculpt new relief geometry inside the app. If you're buying finished STLs from sites like ours and just need to carve them, you don't need that.

The one practical limit: VCarve caps the project size to 4-foot panels. If you regularly carve doors or 6-foot tabletops, Aspire's lifted cap matters. For 95% of bas-relief makers, 4 feet is more than enough.

Best for: Buyers who carve files from specialist studios. Saves $1,400 vs Aspire with zero downside if you don't model.

Carveco (Maker and Maker Plus)

Cost: $15/mo Maker, $45/mo Maker Plus. (Annual plans cheaper.)
Platform: Windows.
Free trial: 14 days.

Carveco came out of the old ArtCAM team after Autodesk discontinued ArtCAM in 2018. That heritage shows: the relief modelling tools at the Maker Plus tier are arguably the strongest in the industry, with sculpting brushes that feel closer to ZBrush than to a CAM package.

The subscription model is the key trade-off. At $15/mo the Maker tier handles imported STLs and basic toolpathing fine, but you can't model your own relief. Maker Plus at $45/mo unlocks the sculpting suite. After three years, you've paid more than Aspire's one-time cost — but you're always on the latest version.

One quiet superpower: Carveco's "smart finishing" toolpath does an excellent job picking efficient cutting patterns automatically. On complex multi-subject reliefs, it can save 20–30% of cut time vs a hand-tuned Aspire pass. That adds up quickly if you're carving for sale.

Best for: Sculptors and modellers who want pro features without the up-front capital hit, or anyone who values "always current" over "buy once."

Fusion 360

Cost: Free for personal use (under $1k/yr revenue from your work), ~$60/mo for commercial.
Platform: Windows, Mac.
Free trial: Free indefinitely for hobby use.

Fusion 360 is the technically-strongest STL handler in this list. It opens million-poly files smoothly, generates flawless adaptive finishing toolpaths, and has full Mac support — which none of the others have.

The catch: bas-relief is not the workflow Fusion is designed for. To carve an STL panel, you're either using the Manufacturing workspace's 3D Adaptive Clearing strategy (which works but assumes parametric stock) or wrapping the STL as a body and using contour finishing (which works but feels like fighting the app). Aspire and Carveco understand "this is a relief panel for a router" out of the box; Fusion treats it as "an arbitrary mesh body in a mechanical project."

For makers who already use Fusion for mechanical or maker-space work, the free tier is genuinely useful — you can carve bas-relief without learning a second tool. For makers whose entire CNC use case is relief carving, Fusion is the long way around the block.

Best for: Makers who already know Fusion, Mac-only users, or hobbyists carving occasionally where free matters more than workflow polish.

Which one should you buy?

Three honest recommendations based on what you actually carve:

• Buy bas-relief STLs every month and carve them: VCarve Pro. The $1,400 you save over Aspire buys a lot of stock walnut.
• Model your own reliefs from photos and sculpts: Aspire if you want one-time cost; Carveco Maker Plus if subscription works for your cash flow.
• Already use Fusion for something else: Stay in Fusion. The bas-relief workflow isn't elegant, but adding a second CAM package is rarely worth it.

One last note: every file in our catalog is tested in Aspire, VCarve, Carveco and Fusion 360 before release. If you carve a DigitalChiselCo file and it doesn't post clean toolpaths in your chosen CAM, that's our bug and we'll fix it — email jolly@digitalchiselco.com with the file and we'll get a working version back to you the same day. Workflow questions about any of these packages: same offer.
