Another study regarding things we should worry about when 3D printing has emerged from the University at Buffalo, and this one is a little mind-blowing. In researching just how safe IP data is while you are 3D printing, the scientists discovered that those wishing to glean data from your 3D printer and consequently steal designs may be able to do so just by standing close by and using programmed sensors from their smartphones. Later, data can be analyzed and then your 3D print can possibly be reproduced with an accuracy as great as 94%. The research team recommends numerous precautions if you are worried about such an attack, using distance from smartphones, printing at high speeds, and employing other tactics with both software and hardware.
