Hi all,  
is there anyone who tried the high temperature resin and stereolithography with a different wavelength than 405nm? Since there is no possibility to get small test volumes to test that, I wanted to ask if some of you have already played around with this material and could share some information on performance etc. Especially I am interested in the brittleness of the samples and the handling with your printer. Would you give it a try at lower wavelength (365nm)?

Thanks in advance!  
Kind regards  
Lennart

Did you ever do any experimentation with this?

The wavelength of the light used by the printer is, to the best of my knowledge anyway, fixed. The frequency is determined by the laser, and while some lasers are tunable, the solid state laser in the Form printers isn’t of that type…
