Hi,
here is a shared object to ehance a bit the G3D T1000 DLP resin printer
use mainly in 100 micron mode to lower it at 66. warning it make a small barrel distortion. mainly on the outside (i will use a software compensation for the slices i think in future)
the insulation size goes as low as 100x76 (/1.50) 66x50 mm but in 66 microns
i used an aliexpress cheap lens here:https://www.aliexpress.com/item/2015-New-Arrival-BIg-Glass-lens-77mm-led-optical-lens-reflectors-fixed-ring-for-20w-200w/32260191766.html
no problem seen with UV
i will post a small tut on T1000 forum to assemble (easy!) http://www.g3dforum.com/index.php
curing time is lowered too:
i use 12sec the 3 first fixing layers
and 0.9s for other slices in 7.5 mic slices with the red resin.
(i think 0.8 or less will be ok but the vat tilt system can't do it on long period of time. it froze at 0.7s in a previous test)
/!\ dont forget to change the size in G3Dlayout ! MULTIPLY ONLY X and Y by x1.5
