We have some important news to share about HackSpace: Issue 81 was the last issue of HackSpace as a standalone magazine, and HackSpace has become part of The MagPi, the official Raspberry Pi magazine. Starting with issue 145, We’ll be adding pages to The MagPi to make room for the stories and tutorials you’ve come to expect from HackSpace.

The ‘Hello World’ of 3D printing is a little boat called 3DBenchy. Benchy models are usually made as a test to make sure that the 3D printer is calibrated properly.
They’re not meant to be actually sailed in – no one would set sail in anything that’s come out of a 3D printer, would they?
No one, that is, except the hardy souls at the University of Maine, in the USA.
This boat’s hull is 7.6 m long and weighs 2.2 tons, and was printed in 72 hours in one continuous print.
That was enough to earn it two Guinness World Records – it’s the world’s largest 3D-printed boat, and also the world’s largest, solid 3D-printed object of any kind.
To produce the world’s largest 3D-printed object, you need the world’s largest 3D printer. The one used by UMaine has a print volume of 30 × 6.70 × 3 metres, and uses plastic filament that contains 50% wood-fibre cellulose to achieve a strength comparable with steel.
