Human-powered laser scanners, based on robust Nema 17 stepper motors. This user-friendly laser scanner is designed to be used in a versatile SLA 3D printer to replace expensive and fragile projectors. High-performance steppers are driven by precision Pololu A4988 stepper drivers, utilizing efficient 1/16 micro stepping capabilities. Moving lightweight mirrors doesn't demand significant torque from the stepper motors, making this level of micro stepping sufficient for reliable operation. The laser positioning system still requires fine-tuning to achieve higher accuracy, but this is expected at this early project stage. Fast laser positioning poses a risk of causing laser distortion, which is attributed to both low-quality mirrors and the inherent mechanical limitations of the stepper motors. However, at lower speeds, this system should suffice for SLA printers as it provides ample exposure time for the resin to interact with the laser beam. The project remains in its initial development phase and benefits from community involvement; feel free to modify, enhance, and contribute back to this ongoing project.
