I bought 1kg resin from local supplier because the USA is too far to send liquid. The wave length of this resin is 410nm, Ec=8.7mj/cm2, Dp=0.16mm. I didn't buy 355nm or lower, because the projector has UV filter.
I printed twice, the thickness of each layer is 0.0635mm, the exposure time of first printing is 10 seconds, no cured at all; the second time is 32s, nothing cured also.
It's my first print, no experience before today.
What wavelength should be? Or what parameter should I set in the print?
