Re: LittleRP2 Information

Just a little question you mention both Acer X152H and the Optoma HD37 to be good for 25 micron, but when I look at the list of projectors you mention, almost none of them can still be bought. They are all out of stock old products. Is there any fullHD 1920x1080 projector which is good and buyable f...

Re: Printy! A DIY Open Source 3D Printer!

Goldi, if you do the math, then if you throw your laser over a distance of around 250mm, then you can get a 60-80mm square build area with little or no deviation. After that if goes bad quickly but 60x60mm is for example not a bad part to work with

resolutions you can achieve on littleRP

I wonder. If the buildsize of littleRP is 60x40, then if I calculate with a 1920x1080 projector, I get roughly 31 micron resolution. Is that achievable with for example a acer P1500 of H6510BD ? Or is a part of the dlp signal just lost? Could somebody please tell what is "realistically" po...

Re: A guide for modding the Acer X152H

Hi. I see that this modification is quite easy, but it is still a modification of course. Could you tell me to how small a projection you can go with a UNMODIFIED X152H ? I am looking to build a new sla printer and currently was looking at acer P1500, H6510BD projectors. Then suddenly I saw this X15...

Re: Bionic Hand

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.
