So, a lot of you no doubt have seen or heard of the Peachy

So, a lot of you no doubt have seen or heard of the Peachy printer. And a lot of people have had their doubts. This video was found on their youtube page shortly after the kickstarter was established, but was promptly taken down, but not before I downloaded the mp4. I’ve republished it on my youtube channel so that it isn’t lost to everyone. The first part is almost identical to their kickstarter video but includes a much longer portion where the guy shows off the hardware a little more including curing some of the resin in a cup by hand. I have no affiliation with them. It also shows some VERY nice closeups of the galvanometer setup.

In your previous post I did comment that galvos are used in most SLA printers. I just wanted to make a note that those galvos are typically closed loop whereas the Peachy galvos obviously are not. Apparently it does not seem to be an issue for the scope of this printer though as the macro pictures of the prints show a very good quality. There is some very detailed information about closed loop galvo performance here: http://www.cambridgetechnology.com/index.php?option=com_content&view=article&id=112&Itemid=107

The galvos on the Form1 are the same as the ones being used on the OpenSL. They are 20 kpps galvos.

The reason I posted this had a lot to do with some of the comments I’ve seen as of late. People saying that the peachy was a gimmick or otherwise wouldn’t work, etc. Also this video has much better shots of the actual hardware for people wishing to get to work on a version of their own sooner than the point which the kickstarter starts delivering.

The UV laser on the glow in the dark tape is an awesome use of the hardware all on its own. I’d love to throw something like that on a wall somewhere and just write vector graphics to it. :slight_smile:

@ThantiK Why do you think there video was taken down?

Think these will work :slight_smile:

I would guess it was taken down because it doesn’t have the best of production values, and they were won over by the Kickstarter theory of “flashy videos sell”.

Anyone know if these guys are on G+? Someone should let them know that this video may not be the sort of thing that will draw in impulse buyers, but is EXACTLY what the techie community wants…

I already backed them, but I feel even better about doing so now that I’ve seen this second video.

josh|MJ from IRC knows this guy.

@Stephen_Baird Also the fact he is smoking doesn’t sell a product to well these days.

I did enjoy his mention that it was the first pack he had ever bought, though.

Brought back some Metal Gear Solid memories there…

Great content, but my eyes went buggy watching. I’m thinking the video quality could have something to do with them removing. Possibly reshooting without auto focus?

@ThantiK I am actually already working on a reprap or repstrap style uv resin printer. Got most of the plans laid out and a few prototype parts printed and in design. It’s very simplistic, but didn’t use salt water as a z axis.

I will post more on it later when I have at least the frame built. Have a few of my EET and engineering instructors interested as well.

I was just thinking about this last night; but there’s no reason you couldn’t use a standard Z platform like all the rest of these resin printers, but use the top down method with the salt water. The biggest issue with the top down method was the huge amount of photopolymer that would have had to be used. Now that we know the resin can float on top, you can just have a vat of salt water, with a build platform that sinks into it.
