Next generation of 3D printers uses anti-grav

It wasn’t so long ago that 3D printers seemed like they could only exist in sci-fi worlds and if you’d heard the guys on star trek talk about the replicator’s anti-grav you’d probably think there was a scripting error – I mean you can get too far fetched, can’t you?

That’s not what Petr Novikov and Saša Jokić thought. They have led a team to develop ‘Mataerial’ – it’s essentially a mechanical arm that emits a thermosetting polymer using a a new form of extrusion. 2 components of the polymer react as it is extruded and then solidify to form the print out.
The shape can be designed in CAD and then printed in full colour on uneven or non-horizontal surfaces.
