3D printing in space

[daivik711 0]

Can anyone please explain how they are now able to print in space using FDM printers?

Is it the same setup or is it different? and if it is different,then how?

The Ultimaker printers require zero modifications to print in zero gravity. They can print on their side or upside down. I have done this a few times - printed with the printer laying on it's side. I thought it might help overhangs but no such luck.

Also Ultimaker once hung a printer upside down from a rope at a show. it printed fine.

However the printers on the space station need to be completely enclosed to prevent small pieces of filament from drifting away and also to filter the air. There are probably several modifications to make a printer safer.
