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.

Boris Johnson is right about Saudi Arabia - but will he stick to his tune in Riyadh?

The Foreign Secretary went off script, but on truth. 

The difference a day makes. On Wednesday Theresa May was happily rubbing shoulders with Saudi Royalty at the Gulf Co-operation Council summit and talking about how important she thinks the relationship is.

Then on Thursday, the Guardian rained on her parade by publishing a transcript of her Foreign Secretary, Boris Johnson, describing the regime as a "puppeteer" for "proxy wars" while speaking at an international conference last week.

We will likely never know how she reacted when she first heard the news, but she’s unlikely to have been happy. It was definitely off-script for a UK foreign secretary. Until Johnson’s accidental outburst, the UK-Saudi relationship had been one characterised by mutual backslapping, glamorous photo-ops, major arms contracts and an unlimited well of political support.

Needless to say, the Prime Minister put him in his place as soon as possible. Within a few hours it was made clear that his words “are not the government’s views on Saudi and its role in the region". In an unequivocal statement, Downing Street stressed that Saudi is “a vital partner for the UK” and reaffirmed its support for the Saudi-led air strikes taking place in Yemen.

For over 18 months now, UK fighter jets and UK bombs have been central to the Saudi-led destruction of the poorest country in the region. Schools, hospitals and homes have been destroyed in a bombing campaign that has created a humanitarian catastrophe.

Despite the mounting death toll, the arms exports have continued unabated. Whitehall has licensed over £3.3bn worth of weapons since the intervention began last March. As I write this, the UK government is actively working with BAE Systems to secure the sale of a new generation of the same fighter jets that are being used in the bombing.

There’s nothing new about UK leaders getting close to Saudi Arabia. For decades now, governments of all political colours have worked hand-in-glove with the arms companies and Saudi authorities. Our leaders have continued to bend over backwards to support them, while turning a blind eye to the terrible human rights abuses being carried out every single day.

Over recent years we have seen Tony Blair intervening to stop an investigation into arms exports to Saudi and David Cameron flying out to Riyadh to meet with royalty. Last year saw the shocking but ultimately unsurprising revelation that UK civil servants had lobbied for Saudi Arabia to sit on the UN Human Rights Council, a move which would seem comically ironic if the consequences weren’t so serious.

The impact of the relationship hasn’t just been to boost and legitimise the Saudi dictatorship - it has also debased UK policy in the region. The end result is a hypocritical situation in which the government is rightly calling on Russian forces to stop bombing civilian areas in Aleppo, while at the same time arming and supporting Saudi Arabia while it unleashes devastation on Yemen.

It would be nice to think that Johnson’s unwitting intervention could be the start of a new stage in UK-Saudi relations; one in which the UK stops supporting dictatorships and calls them out on their appalling human rights records. Unfortunately it’s highly unlikely. Last Sunday, mere days after his now notorious speech, Johnson appeared on the Andrew Marr show and, as usual, stressed his support for his Saudi allies.

The question for Johnson is which of these seemingly diametrically opposed views does he really hold? Does he believe Saudi Arabia is a puppeteer that fights proxy wars and distorts Islam, or does he see it as one of the UK’s closest allies?

By coincidence Johnson is due to visit Riyadh this weekend. Will he be the first Foreign Secretary in decades to hold the Saudi regime accountable for its abuses, or will he cozy up to his hosts and say it was all one big misunderstanding?

If he is serious about peace and about the UK holding a positive influence on the world stage then he must stand by his words and use his power to stop the arms sales and hold the UK’s "puppeteer" ally to the same standard as other aggressors. Unfortunately, if history is anything to go by, then we shouldn’t hold our breath.
