**Meetup Quick read** Is Air-Gap the most secure connection to a 3D printer? In last week’s meetup, we discussed about **Cybersecurity in Additive Manufacturing**. Years have passed since the first additive machines were created. And in the meeting, people could still remember the days where a standard PC with MS-DOS was used to drive a powder-bed fusion process. At that time, transfer of data was done by 3 inch floppy media. And many people still argue, that today’s pen-drives (or “USB-Sticks”) still are the most secure way to transfer the manufacturing data onto a manufacturing system. Do you agree? Join the meetup today at nine and continue the discussion or post your comment below!
