Is it possible to attach a laser engraver to a SLA / resin 3D printer?
Not with consumer equipment.
FDM printers are functionally three-axis motion control machines: &quot;extrude quantity W material at position X Y Z, continue to next W, X, Y, and Z.&quot;
Adapting it to control a laser position is a relatively simple task, because most of the logic is the same. &quot;fire laser for W duration&quot; instead of &quot;extrude quantity W material&quot;. Moving the laser around is functionally similar to moving the print head around.
Consumer SLA (aka &quot;DLP&quot; or &quot;mSLA&quot;) is an entirely different logic, a different process. It is effectively layer-by-layer snapshots, rather than multi-axis motion control. They do a whole layer at a time, then lift the whole object up for the next layer: &quot;flash layer 1 for W duration, lift bed Z, proceed to layer 2.&quot;
Professional/industrial SLA printers that use lasers exist (like SLS), but they're tuned to precisely cure photopolymer resins, not cut things.
