Designed this to test out different resin bridge properties. With the settings I used it took about an hour and a half or so to finish.
Not sure if it would work for FDM printers, but go ahead and try it! Wall thickness of bridges is 1mm.
Tested so far Siraya Tech blu. Surprisingly it will complete a bridge even up to 18mm, however the layers separate since the initial bridge layer has nothing to hold on to and it's only .05 mm thick it doesn't stay tight.
Tested:
Siraya Tech blu
used 3.3 sec exposure time, 30 sec bottom exposure time, 10 bottom layers
Printer:
Phrozen Sonic Mighty 4k
Rafts:
No
Supports:
No
Resolution:
.05
Blu
Notes:
used 3.3 sec exposure time, 30 sec bottom exposure time, 10 bottom layers
15 min cure time (doesnt matter really)
Since you're not using this for anything structural, it doesnt matter really, just enough to cure all the goopy resin is fine.
