There's no doubt that once it improves to a certain level and reaches a certain price point it has the potential to change the world and impact on many different market segments. Just as the entertainment industry is fighting heavily to protect their outdated business model through legislation, do you reckon that manufacturers and many others that could be in danger from 3d printing will start to push for legislation to heavily restrict and control their usage? We've already seen the potential to print weapons such as guns. Will events like this really just play right into their hands? Or do you foresee a different future?"
