Where do I get good artwork (vectors and 3D models) and how do I prep AI-generated images for carving?

Vector art (2D designs)

• Buy: Etsy (a huge SVG market), Creative Fabrica, Design Bundles, Vecteezy. Search "laser/CNC SVG". Check the license for commercial use.
• Free: Openclipart, SVG repositories, and government or heritage archives. Art old enough to be in the public domain is fair game, but check the date rule for your country, since it varies and changes over time.
• Make: the software's own drawing tools; trace cleaned images (see the bitmap-trace entry); Inkscape for heavy vector editing.
• Quality test before buying more from a seller: import one file. Clean closed vectors, sane node counts and real curves (not thousand-segment polylines) mean a good source.

3D models

• Clipart made for the software first: the library on the software maker's design-and-make site and vendors selling clipart for the software import cleanly as components.
• STL marketplaces: CNC-specific relief models on Etsy, Cults3D, STLFlix and similar. Check it is a RELIEF (one-sided, carvable) and not a full-round printing model, and remember the no-undercuts rule.

AI-generated images to carvable art (the new workflow)

AI images are raster pictures, so the work is conversion:

1. Generate FOR conversion: prompt for "black and white line art / stencil / silhouette, high contrast, clean lines, white background." A contrasty graphic converts far better than a photorealistic render.
2. Clean the raster first: boost contrast, delete stray specks, close gaps (any image editor).
3. Trace with Trace Bitmap (see the jagged-trace entry: run Fit Curves afterward) or with Inkscape's edge or centerline trace.
4. Repair for machining: weld overlaps, close vectors, run the Vector Validator, delete double outlines, THEN check every gap against your bit geometry (see the minimum-detail entry).
5. Sanity-check that the design is physically carvable: connected stencil topology for cut-throughs. Islands need bridges, the classic stencil problem.

For 3D: AI image to depth-map or relief converters exist, but expect heavy cleanup (Smooth Components and, in Aspire, the sculpting tools). Treat the result as raw clay, not a finished model.

Pro tips

• Copyright: check the terms of the AI tool you used, because rules on commercial use and ownership vary. Trademarked or branded content stays off-limits, same as any clipart.
• Build a personal library folder of cleaned, proven files. Your fastest "source" is work you have already fixed.
