I thought this would interest you guys. My first 3D printer used resin so I can't recommend this type of printer enough for small scale models. Layers almost don't show, it consumes much less electricity, is a lot easier to use and way less error-prone than extruders. In short the OLO is a 3D printer that costs only 99$ because it uses your smartphone to cure resin. The resin is set to cure with normal light instead of UV light, and unlike UV resin can be washed with warm water, not alcohol. The build size is very small (128x72mm, Z axis 52mm), so it seems perfect for miniatures and smaller props. Detail looks decent, too.

VEry interesting! I imagine that special resin is costly though. We'll see!

This is such crazy cool technology these days.. I thought the electro mechanical process rocked.. looks like chemists are the future!

I really want this to be legit, so I can grab one, but something about the Kickstarter and website makes my spidey-senses tingle.
The tech won a 2012 award, but it's only going on sale in 2016. There is zero information on print volume per bottle. It's a tech related KS with an account with zero previous Kickstarter kistory. No official post kickstarter price per bottle info. No info on how much resin you need to pour in to print ? Do I dump a whole bottle in there every time I print, or just guess how much to pour in ?
and most importantly... It uses light sensitive resin which they sell in translucent bottles. Why are the bottles not opaque ?

The light/oxygen stuff us tre cool, that is probably x number of years away for even hobbyists, but I will be ready at that time.

I think if this technology is ready, a better version will be available soon. I'm willing to wait.

yet i've seen people back out soup making kickstarters... I've checked the video it seems to be cool and all, but i have my reservation about it. the one thing that doesn't add up is how can a simple light from a cell phone be able to know which layer to print ? i mean come on, look at how it works from that video. i have a really hard time to believe that could even work ? so i have gone over google and tryed to find out about resin 3D printers... seems to me like there are no real other choices asides fromt hat one. i have seen some laser powered ones too. but this seems to be the only real one in marketting. found their website as well... www.olo3d.net/leaving your phone open for 3 hours straight on the highest brightness setting is asking for disaster in battery power. there is a video showing the process in a time lapsed thing and it took like 3 hours to print something. let's just say i'd preffer it to be on its own power source. i still have a problem with the inverted plate and how the resin can actually be cured by layers. wish we had more details on the process...

To be honest, if this is legit, I would invest an extra $50 to buy a cell phone just for this purpose, instead of using my regular cell phone.
My biggest concern in the price of the resin. It would be cool if it worked, but not economical at all at the rumored $10 a (1oz?)bottle.

Here's a TED talk on the process a company called Carbon invented and which OlO uses that was given by Carbon's CEO: And here's Carbon's website. They invented the process for commercial use. carbon3d.com/
Olo appears to be a stripped down, less resolution, and way slower, version of their Carbon 3d machine that uses an Iphone for its computing and lightsource.
I can't find any info on if the Carbon and OLO companies are related in any way to each other. My guess would be OLO is licensing the tech from Carbon since Carbon owns the patents?

yeah thats something i'd want if its affordable. but OLO is definitely much slower. takes 3 hours to create the ball they did in 6 minutes.
but thanks for the video, now i understand the process.

To wit, OLO doesn't use continuous printing. It uses mechanical peeling, which consumes sheets you put at the bottom of the vat and have to replace every 3 print jobs or so. Sold at 5$ for 20 sheets. Doesn't look so convenient anymore, except for the very small form factor and being able to print almost anywhere.
The Carbon printer uses continuous with a fancy nanocoated vat, but a cheaper way to do it is to go top-down with a projector. Typical DLP printer, but the layers are a continuous animation synched with Z motion instead of fixed pictures for every layer. What they don't do in the video, and which you could do, is fill most of the tank with salt water and a small layer of resin floating on top.
