DLP projector options

This is the place to discuss DLP projectors, UV Lasers, Galvanometers, LCD screens and similar display devices. Also discussed are optics in general.

DLP projector options

Postby avinash3333bhat » Mon Jul 20, 2015 1:04 pm

Hi All,

I have narrowed down the search for dlp projector to these three:
1. Infocus in220i
http://www.infocus.com/projectors/offic ... ries/IN220
2. Dell 2300MP
http://www.projectorcentral.com/Dell-2300MP.htm
3. Mitsubishi xd110U
http://www.projectorcentral.com/Mitsubishi-XD110U.htm
Can you guys tell me which one will be easy to mod...
Also can I use a lens to increase the build area size? since these resolutions won't give me a big enough build area & i'm also on budget so can't buy expensive ones...

First things, don't take the infocus in220, low native resolution=low printer resolution or small build area.
The two other don't have a good resolution too, maybe if you want a large build area you have to choose a 1280 or more projector, not ready but native!! Very different.

After for the optic and the general quality I don't know, maybe other users can tell you.
To have your final resolution you make x_build_area/x_native_resolution, 100mm/1024=97um
And the same for the y axis

A good printer can down to 50-25um

Thank you for the reply.
I will stick to 100micron X-Y resolution.
I believe Z -resolution will depend on steps_mm. So I can go upto 30 micron for Nema 17 with 1/16th stepping. Will there be any issue with mechanical strength when the resolutions in different axes are not matching?

No problem to have different resolution but if you want a best result think to put your model with the good orientation to have the best result.
