Wood relief carving with a preview before the chisel

A wood relief is a shallow object, so the background occupies a lot of the visual field. If the source has a busy room, a fence, or a crowd, the relief becomes a field of small bumps. Crop to the subject and flatten the border. A quiet background makes the face or the ornament read at a glance.

Grain is part of the result. A strong cathedral figure can compete with the relief, while a straight grain supports it. For a first test, choose a straight-grained offcut of the same species. For the final piece, decide whether the grain should run horizontally or vertically through the subject.

A cutter needs room to move. A deep relief with narrow valleys may be unreachable for a large bit, and a small bit may take too long or break. Set the relief height with the cutter diameter and the stepover in mind. The manufacturing check reports a detail figure against the tool size for this reason.

The stock has to cover the relief plus the base plus a safe margin for the fixture. A thin board can bow or break through. Decide how the blank will be held, where the origin is, and how the cutter will enter and exit. The STL is geometry; the workholding is your plan.

The relief exporter builds a top surface, side walls, and a bottom face. That closed mesh is easier to inspect and slice than an open height sheet, but it is still not a toolpath. Open the file in your CAM package, check the scale, and inspect the steepest slopes and the smallest features before you generate a path.

If the mesh has thin walls or isolated islands, fix the source or the relief settings. A CAM package can sometimes repair a mesh, but a repair can change the shape. It is better to catch the problem in the preview than to discover it after the toolpath is calculated.

Sanding raises fuzz on some species, especially across the grain. A finish can darken the recesses and increase contrast. Test the finish on the same wood and the same relief depth. A finish that looks good on a flat board can make a shallow relief look muddy.

Keep the offcut, the file, and the settings with the job. If the customer wants a matching piece, the same starting point and the same finish produce a more consistent result. The workbench is the preparation; the wood and the finish are the craft.
