I wonder if you're able to get accurately sized objects for gears and such. The resin for photolithographic printers normally suffer from shrinkage after printing.

Looking at the videos, a few milliseconds would correspond to ~1 drip, maybe 2. It isn't going to introduce a real significant flaw in anything.
That could be enough to cause X-Y positional problems though.
It depends on how fast the resin cures. I have the idea that it sends (and repeats) the same layer for a bit longer than milliseconds, so I don't see it mattering.

Indiegogo link @ http://www.indiegogo.com/projects/the-peachy-printer-the-fir... I really like what i've seen so far :) But i do not understand why they are running a kickstarter and an indiegogo campaign at the same time for the same product with the same setup and rewards. Only the campaign duration is slightly different. Anyone got any ideas why this would make sense? PS.: On indiegogo the early bird special is st…
Advertising in two similar, but not exactly the same markets at once? Although, I feel like the indiegogo should have some sort of outreach to it as well. Like, "$25 gets you resin or a t-shirt and you (along with 5 other people) will sponsor a printer for a school" or something like that. Or perhaps focus on how the money from indiegogo will be used to make the software more accessible and easy to use for all people…
It's strange that they chose a fixed-funding model for indiegogo. Even though the kickstarter has reached its goal, the indigogo project might not.
Aside from the lower price of the remaining early bird specials, is there any reason to fund it through indiegogo instead of kickstarter?

Perhaps, with slightly more hardware, you could rig it up to kill the power to the laser if the sound level dropped to zero (which is typically how computer audio hiccups manifest). Printing would stop for a moment, but you wouldn't have the laser curing anything it shouldn't.
This doesn't really work, though, because to the 3D printer, 0 volts is a valid signal in the domain of the input. Never use a value in the domain of your input as a null value. Additionally, it is difficult to define what the sound level of a continuous signal really is, since it is usually computed using an averaging, integrating, or low-pass filter (not sure which.) Just like an old-fashioned VU meter, it takes a…

Only if you consider a centered rod of minimum thickness "valid".

> pretty brittle at least on the Form1 This is true (at least on the SLA printer I've used). The problem is that the resin never stops UV curing, so it just gets more and more brittle over time. Small parts get really fragile (Maybe you can paint/cover them to avoid this - I'm not sure). FDM or SLS printers are generally better with functional parts, while SLA is better for prototypes that don't need to last.
What if you use a spray primer to completely coat the object?
Not a clue! You'd have to ask somebody more qualified than myself.

#98It's clever and really neat. That said, please don't think you are going to get parts of the quality, accuracy, surface detail and durability attainable through other more established methods.
The only reason I am funding it is to support someone thinking outside the box. I really have no use for it due to the issues listed above. I'll probably gift it to someone who might. I've done that a number of times with KS projects.

#100This is rad! As I looked through the list of people involved, I learned that one of the guys doing it was a close friend of mine through EE school.
And I have to chuckle a little bit about how much of a prairie farmer hack this is. People around here build crazy hacks like this all the time on their farm equipment, glad to see them getting some publicity!
