For our event at the rapidpro we are printing some example pieces.

this print came out really nice, i'm printing a second one with 1.8 seconds exposure time.
i've also raised my vat with 4.5 cm to increase build size.. and that worked

Cheers,

HP, amazing results, again! Remind me, what projector and resin are you using?

Hi Dangre,

i'm using a custom UV 405nm LED DLP projector
the resin i used here was sf white from makerjuice.

Hp. What do you mean with a modified dlp? What make of projector did you modify and how please?

hi educa,

so i am using a very special projector, I did not find anyone selling it in Europe so i had to go to somewhere else.

the Projctor has a very small form factor 6cmx11cm and has a UV LED that you can control the intensity during the print.
so i can use full intensity during exposure and during blank, turn it down to 30% intensity.

so what else to mention about it.. it has HDMI input and can be used with the raspberry pi for example..

Kind regards,
hp

Hi Sodium,

this link is where i buy it.
light engine

This is an expensive toy, but on the other hand it also gives you very fast curing times I guess.

I am not looking for the fastest build/curing times but good quality so I think I'll stay with a nec 1024x768 which I have lying around here to test and then a acer p1500 if testresults are good.

Hi Educa,

it not only gives me fast curing times, but I have noticed the uniformity of this light engine is really excellent.

with the off the shelve projectors this is a problem.
