Draw in the air with a 3D printing pen

We live in the future. The lack of jetpacks gets a pass.

There is a moment in the Kickstarter video for the 3Doodle pen (which I found via the New Scientist's Paul Marks) which took my breath away. It comes after the introduction, when the pen is used to draw its own logo; and it is as simple as drawing a cube.

Only… it draws all of the cube:

The pen is essentially a handheld 3D printer. By extruding heated plastic through the nib, which then cools solid almost instantly, it lets users "write" in thin air, creating anything from relatively simple stick figures:


To insanely complex wire art:


(The 3Doodle team have joined forces with a bunch of Etsy wire-artists to show off the pen. The work above is by Ruth Jensen.)

On one level, the pen is clearly "just" a $75 toy. A few artists might find use for it (but then, artists find uses for anything), and it looks like it would be amazing fun to just goof around with, but it is difficult to imagine it revolutionising anything. And I'm pretty sure the launch-to-penis time (the time it takes for a radical new creative technology to be used to make crudely-drawn cocks) will be in the microseconds.

At the same time, though, it's a demonstration of just how close-to-market mainstream 3D printing is. The over-arching technology behind the 3Doodle genuinely does have the potential to shake up manufacturing — if not by letting people print consumer goods at home, the utopian dream, then at least by radically restructuring supply chains in conventional production.

The pen is currently less than $1000 short of its $30,000 goal on Kickstarter. I really want one.

It's official, Brexit means breakfast — or at least as far as John McDonnell is concerned

The shadow chancellor is not the first politician to confuse the UK's EU exit with the morning meal.

Who doesn’t hate a chaotic breakfast? As the shadow chancellor John McDonnell clearly knows, there is nothing worse than cold toast, soggy cereal and over boiled eggs. The mere thought of it makes the mole shiver.

In the middle of a totally cereal, sorry, speech this morning on Brexit and its impact on the economy, McDonnell expressed his fear that the government was “hurtling towards a chaotic breakfast". 

Addressing the Institution of Mechanical Engineers in London, he argued that Theresa May’s government could decide to opt for a Brexit deal that favoured Tory “special interests" at the expense of the rest of the country.

Warming to his theme he accused Tory cabinet ministers of looking to “cook up” deals for their “friends in the City of London”, before making the powerful point that "Tory voters don't want a bankers' breakfast any more than I do". Bang, the same foodie blooper dropped twice in one speech. It seems that breakfast really does mean breakfast, or at least as far as McDonnell and the Labour Party are concerned.

He can take solace in the fact that he is not the only politician to fall into this particular verbal trap, it seems a fear of a lousy breakfast is shared by ministers across the political spectrum. In his speech to Conservative Party conference, Welsh Tory leader, Andrew T Davies, trumpeted the fact that the government would make the morning meal its top priority. “Conference, mark my words,” he said “we will make breakfast. . . Brexit, a success.” The Mole loves to hear such a passionate commitment to the state of the nation’s Weetabix.

And, it’s not just politicos who are mixing up the UK’s impending exit from EU with the humble morning meal. The BBC presenter Aaron Heslehurst was left red-faced after making multiple references to “breakfast” during a live broadcast, including one where he stated that it “had opened up a brave new world for UK exporters”. Who knew?

And there was your mole thinking that the hardest part of breakfast was getting up and out of the burrow early enough to enjoy it. Food for thought indeed.


I'm a mole, innit.
