right, but the rate of dissipation would be a huge problem for the additive technique described in this article. Plus the lack of gravity means that the molten metal would adhere to the existing component very very differently. Essentially it would mean designing the process from scratch - with almost no ability to test on earth during the design process. Not sure how effective computer modelling is for that type of thing :)
