An SVG can preserve sharp vector outlines, but open paths, duplicate lines, tiny cut-outs and unclear usage rights must be resolved before extrusion. Define the physical size, extrude the closed shape and inspect the exported mesh again.
Download the English project worksheet. Open it as UTF-8 CSV, replace the guide context with your project inputs and record observations separately from acceptance decisions. Blank cells do not indicate a passed check.
Establish permission and the intended product
Record the creator, exact source and licence or written permission. A free download is not automatically permission to modify or sell an object. Retain required credit, the licence link and a record of changes.
Specify width and height in millimetres, whether the artwork becomes raised material or a recess, and separate base thickness from relief height. For small text, use the keychain readability checks. If the input is a photograph, first choose between relief, lithophane and a complete model.
Prepare clean, closed outlines
Check that each path closes. Remove duplicate lines, unintended overlaps and hidden objects. Where required by your workflow, convert strokes into filled outlines. Preserve negative spaces such as the centre of an O.
Measure the smallest line and opening
After scaling, measure the thinnest bar, narrowest opening and gap between shapes. These are design inputs, not universal printer limits. Agree the relevant process constraints before deciding whether to enlarge or simplify a feature. A viewBox defines drawing coordinates, not by itself the intended physical millimetres. Apply the same scale factor to every detail: if a two-unit line becomes 0.8 mm, record 0.8 mm and ask whether it is suitable for the chosen process.
A controlled simple extrusion
The stored practice file is an original rectangle measuring 30 × 10. A deterministic script read its four corners and extruded them by 3 mm into a closed ASCII STL. The output had 12 triangles and reread dimensions of 30 × 10 × 3 mm.
| Check | Recorded result |
|---|---|
| Closed contours | One rectangle |
| Extrusion | 3 mm |
| STL triangles | 12 |
| Dimensions | 30 × 10 × 3 mm |
| Mesh checks | No open or non-manifold edges; positive volume |
Download the SVG input and STL output. Inspect closure, dimensions and mesh edges locally. The result supports only this straight, single outline. Curves, compound paths, letters, slicers and physical prints were not tested.
Reopen the mesh and inspect the smallest features
Measure the STL's width, height and relief thickness. Check that holes remain open and every separate shell is intentional. The STL inspection guide covers that handover. A clean-looking vector does not prove a closed exported surface.
Reject an unresolved logo before extrusion
For a second editorial example, imagine NOOR drawn as loose strokes over an overlapping background, with no font-use evidence. Reject it before extrusion. Establish usage rights, convert text to closed contours, combine the background deliberately and inspect both O counters at final size. Then begin a fresh mesh check. This is a planning example, not a tested logo.
Stop for unknown permission, licence restrictions on modifications, self-intersections, closed-up negative spaces or unspecified size and relief height. Request a clean source or agree a simplified design.
Match the file to the ordering decision
For a name tag, the final dimensions, readable text and attachment determine the product. Carry those decisions into custom keychains, with the vector source and required quantity.
For an illuminated desk or wall logo, request a custom logo lightbox, supplying vector artwork, outside size and placement. A relief file defines shape only. The enclosure, lighting, mounting and included components require a separate product agreement.
