Eddie's article mentioned he was using a laser for the curing, so I suspect the desk lamp is probably just for post-curing (the equivalent of putting the model in sunlight). But, I can see the liquid all over the platform, so your observation that there is a curing problem is correct. I'm guessing it's materials (it looks like he's using SLA resin), but it could also be an inaccuracy between the jetting and laser.

I think the real stumbling block here is going to be the chemistry – the materials composition. But, it's hard to tell. It's basically cobbled together and the wax printer components might not be able to produce a stream that is fine and stable even if he knew the exact formula for Stratasys' various Objet offerings.
