On: 3D printing boats is becoming standard practice

Does this loose more microplastic than other boats?

Almost certainly; look at the rough plastic surface of it. Sea water and UV will almost certainly degrade this boat and have it shedding loads of plastic. The only upside is they didn't choose to cover it in glitter, but such coatings are certainly optional for traditional boats...
