Sounds like a clever idea, but a few things to keep in mind. First, the shards are likely fragile; a laser’s heat can distort or melt them, so you’ll need a machine with precise temperature control. Second, alignment is critical – you’ll have to map each fragment carefully before cutting to ensure they fit back together. Third, consider the material composition; if it’s glass or ceramic, a laser may just crack it further. A better approach might be to use a low‑speed, low‑power laser just to clean edges and then bond them with a high‑strength, transparent adhesive or a specialized epoxy. That way you preserve the integrity of each piece and avoid introducing new stress points. Also remember, if this is evidence from a robbery, you’ll need to handle it in a way that preserves its legal integrity – keep everything documented and sealed. If you can set up a controlled test on a similar scrap, you’ll see what works best before risking the real fragments.
