Build Your Own SLA/SLS

Sorry, I meant to say I have a few polarizers that at least don't block much UV light. I've recycled them from various old junk and I'm going to see how well they work and what I can actually do with my LCD once it gets here...ebay shipping... An old LCD I took apart to see how easy it was has the p...

I'm from Canada and I'm in the same boat. If you look on eBay for FEP film or Teflon or anything similar it's mostly baking supplies or film with styles or holes hut into it, which is kin of useless. If Teflon film would work and if it doesn't need to be 100% transparent there are these two sellers:...

Also, 21"? Nice. I was thinking that if I can get my miniature printer going and figured out all the kinks I could try something of that size eventually.

OK, well I already have some optics ordered for the LEDs, as well it is a very small LCD (around 3.5") and I will be removing some of its filters and anything unnecessary like back-light propagators of whatever they're called. I even have a non UV blocking polarizer to use as a replacement in c...

Stupid small screen, I couldn't see who the posts were from and I thought it was the same person again. Thank you to everyone who has replied.

Perhaps the relay would be easiest. I'm only looking at a maximum 10W set of LEDs. No I don't plan on PWM, I'm trying to make this as simple as possible, maybe voltage dimming/control if I need it via a dial no software or anything. Also I cannot find consistent accounts of the mosfets on the teensy...

OH, and would it be possible to do a similar thing with say the hotend pins in case the teensylu doesn't have fan pins? Or even power the LEDs off of the hotend pins? I mean, what sounds a lot simpler and convenient than doing some sort of relay setup for the LEDs.

Nice. I don't suppose you could post some more specifics of what you did, or a screenshot of what you modified in the firmware? I'm not trying to be lazy, I just want to see what you did before I try and potentially blow my board or LEDs, I'm still a noob at programming and such. Thank you.

Fascinating, that would simplify or at least shrink the board complexity of my project. What is the minimum specs required for an arduino to run common firmware? Would anything with an At-mega 2560, 1280 or possibly lower work?

Hello, I'm DoctorProfessorGuy, I'm terrible at names and I am new to SLA 3D printing. I'm trying to create a simple 3D printer based off of an LCD and UV lEDs, not unlike the ibox nano Kickstarter project. I've got almost everything down pat, I just need to get a way to control my light source. I wi...
