The spota 470 used a very slow photoinitiator Hnu-470. Yhe ZVE200-V470 uses a very fast and sensitive photoinitiator. They can also blend just about any resin to work from UV - 500nm.

Yesterday I tried to contact Spot-A materials through their new contact form. And they answered me in the day ! Here is their answer (I though it would be instructive for all of us):
"Hello,Maybe I will the harbinger of bad news, but is this th eprojector you are taling about?http://www.projectorcentral.com/AAXA_P2_Jr_pico_projector_review.htmIf yes, it is listed at 55 Lumens, with a LED source, so tentatively around 20 Lumen of blue light. LED projectors tipically use 455nm blue LEDs which is not optimal for resin curing.It is possible, theoretically, but you will end up with a very underpowered setup, that will need extremely high exposure times (maybe even minutes per layer) and you will still not achieve a reasonable cure rate, so that the resins will remain soft and gel like. You shoudl look into more powerful light sources and as close to 400-425nm as possible for visible light (385nm would be even quicker)Sorry, for the bad news"

That close the subject.
