Is it possible to attach a laser engraver to a SLA / resin 3D printer?


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: "extrude quantity W material at position X Y Z, continue to next W, X, Y, and Z."

Adapting it to control a laser position is a relatively simple task, because most of the logic is the same. "fire laser for W duration" instead of "extrude quantity W material". Moving the laser around is functionally similar to moving the print head around.

Consumer SLA (aka "DLP" or "mSLA") 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: "flash layer 1 for W duration, lift bed Z, proceed to layer 2."

Professional/industrial SLA printers that use lasers exist (like SLS), but they're tuned to precisely cure photopolymer resins, not cut things.

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

High Torque, High Precision and Long life is Cloudray's core advantage
Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.
Higher Resolution,Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.
Sturdy structure, extremely long life
High quality materials including bearings and shaft made in Japan
Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.
Short length and light weight allow them to be used in highly integrated systems
