The form factor here is cool, but as someone whose been resin printing a bunch lately, the pitch to carry it around in your pocket sounds questionable.

1. Where are you going to store the resin? It isn't good to touch it. Are they also expecting people to carry around somewhat toxic resin in their other pocket and then make a little puddle on the ground to print? Resin printing is messy and cleaning is hard. Make sure to carry isopropyl alcohol in your other pocket.

2. It produces toxic fumes while printing that you need to exhaust. So you at least need a mask.

3. It takes hours to print on a large machine: you need a model file, to edit the model to print in resin well and then the actual print can be multiple hours long. Not to mention multiple print failures which is often the case.

Everything mentioned about the surgical application sounds possible today, but it's still not fast enough or reliable enough in that scenario. Also... Resin isn't that strong, you want to graft it to a bone, what?

Raw materials aside, a tiny printer can go places a large printer cannot. Space? Deep sea? Inside other machines? Or on the tip of a robotic arm to do print little parts right onto their permanent place like a spider placing silk? Who knows!? 99% sure the "in your pocket" statement is more like "smaller than a breadbox", as in, it's plain-as-day comparisons of size, not use.

The size of the printing mechanism is an innovation for sure, but I think after you add up all the other components to make a functioning printer you end up at nearly the same size: a resin vat, space to print, various leveling mechanisms, filters, UV light shield etc - the form factor doesn't really change all that much.

Resin isn't toxic. The problem is that resin can cure under your skin and the only way to get rid of the resin is for your immune system to do it. So people develop allergies against cured resin, which tends to cause more damage than the resin itself. Even after you have developed a resin allergy, there is generally no long term damage as long as you stay away from it and don't trigger your allergy.

That does sound pretty toxic to be fair.
