Print your own rabbit on The Replicator, Makerbot’s 3D printer [Video]
Makerbot’s Replicator is about the size of a microwave. It can print 3D objects from the 1KG coloured spools that sit on the rear of the machine. There are two materials available: ABS, similar to Lego bricks; and PLA, a corn-based biodegradable material.
Watch The Replicator in action in our video
There are two different versions of the Replicator machine, one that allows for two colours to be printed at once, which will enable you to print a blue and green globe; and a single colour machine. The dual colour machine costs around $2,000, while the single colour machine costs around £1,750.
The replaceable spools cost around $50 each and there are around a dozen colours available – including glow in the dark.
How does it work?
To print something you need to download the pattern. There are around 15,000 pattern designs on the Thingiverse website. These include figurines, model animals, buildings and cars, chess pieces, jewellery, containers, decorations and tools.
The pattern is then programmed into the Replicator either by an SD card or a USB connection from your PC. You can then choose the colour and scale and set it to print.
The 3D prints, depending on the complexity, size and quality, can take around 15 minutes, to several hours. The largest they can be is 8.9 inches x 5.7 inches x 5.9 inches, although some larger patterns can be made up from a number of components. We saw a wendy house and a toy castle built that stood over a metre tall. Within the wendy house were bookcases with individual books on the shelves, and some of the printed characters had tiny printed hats and mobile phones.
What are the practical applications?
The Replicator is likely to appeal to hobbyists, but beyond toys there are practical applications, such as the printing of prototypes of models for designers. Other items such as tools and machine parts can be printed, although the material is still a little too brittle for heavy use.
