Another day, another unusual resin printer.
http://www.indiegogo.com/projects/lumifold-the-foldable-photo-activated-resin-based-3d-printer
After further inspection, this one is weird/fishy. No video, the blurb mentions kickstarter even though this is indiegogo. Flexible funding (which is a bad sign) but on the other hand a very low funding goal.
There are a couple ultra short videos up on YouTube if you search for it, but nothing really demonstrating the device properly. It’s an incredible achievement if it’s real, though.
Maybe copycat of the peach?
Fishy doesn’t even comes close. It has a ‘why Kickstarter’ block on an indiegogo campaign. The Project Owner has several totally failed campaigns. It has no part about the author and the production scheme is simply the most silly thing I’ve ever seen. Plus, why does he need 1500 only?
Also, this requires an overhang projector, which is almost not mentioned at all. Mounting a projector pointing down in a vibration-proof manner requires a massive rig, rendering the fold-able/portable feature moot.
This is a sham just like the peach.
@Lance_Seidman the peach is decidedly very much not a sham. The methods he’s using are sound in practice, and it’s not uncommon for galvanometers to be driven via a DAC…which is exactly what your sound card is.
@ThantiK I don’t doubt that part, I can even use a MCP4725 12-bit DAC to do the same w/small Microcontroller.
I’m just wondering about the Energy levels, usually 500 to 3000 mJ/cm^2 but obviously depending on the resin varies to cure.
But really the Drip system is what’s not selling me personally as for the size of the product.
@Lance_Seidman About that drip system, how does the printer know when to fire the laser if the rate at which the droplets actually hit the reservoir below is highly variable?
@Lance_Seidman , I’ve spoken directly with Josh from MakerJuice; he states that the mUVe uses a 20mw laser, and the resin will cure in as high as 420nm light. The mUVe makes some pretty quick passes over the surface with that laser and gets good results from it. A 5mw laser should even be able to cure the layers, and with a slow enough drip time, you’ve got lots of time to spare. What will end up happening is that you’ll be able to speed up your drop frequency and print speed with a more powerful laser. The peachy kickstarter used to have an extended video up on their youtube that I grabbed - I’ll upload it at some point and let you guys take a look at it. He shows the process in a plastic cup with him holding the laser assembly. He’s got something here…he really does.
@Mike_Trieu_MegasChar Questions I have as well.
@ThantiK Believe me, I hope you’re right.
