I'm working on a 3d printer project, where I need a laser that can melt a fine powder in a pattern.
In my search for a suitable laser, I came across some articles on how CD burners work.
Some articles claimed that the laser emits light in a specific wavelength that the dye in CD-R's respond to, others claimed that besides light, heat was also emitted (IR light I guess..).
Question is, how much heat can the well focused beam of a CD-burner's laser produce? (time/temperature ratios...)
And does anyone know how to remove the laser, and make it work outside the drive?
Also, the magnetic array that focuses and moves the laser, can this be controlled manually somehow?
I guess these things vary ALOT from drive to drive, but just an example would be nice
