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.

Theresa May’s stage-managed election campaign keeps the public at bay

Jeremy Corbyn’s approach may be chaotic, but at least it’s more authentic.

The worst part about running an election campaign for a politician? Having to meet the general public. Those ordinary folk can be a tricky lot, with their lack of regard for being on-message, and their pesky real-life concerns.

But it looks like Theresa May has decided to avoid this inconvenience altogether during this snap general election campaign, as it turns out her visit to Leeds last night was so stage-managed that she barely had to face the public.

Accusations have been whizzing around online that at a campaign event at the Shine building in Leeds, the Prime Minister spoke to a room full of guests invited by the party, rather than local people or people who work in the building’s office space.

The Telegraph’s Chris Hope tweeted a picture of the room in which May was addressing her audience yesterday evening a little before 7pm. He pointed out that, being in Leeds, she was in “Labour territory”:

But a few locals who spied this picture online claimed that the audience did not look like who you’d expect to see congregated at Shine – a grade II-listed Victorian school that has been renovated into a community project housing office space and meeting rooms.

“Ask why she didn’t meet any of the people at the business who work in that beautiful building. Everyone there was an invite-only Tory,” tweeted Rik Kendell, a Leeds-based developer and designer who says he works in the Shine building. “She didn’t arrive until we’d all left for the day. Everyone in the building past 6pm was invite-only . . . They seemed to seek out the most clinical corner for their PR photos. Such a beautiful building to work in.”

Other tweeters also found the snapshot jarring:

Shine’s founders have pointed out that they didn’t host or invite Theresa May – rather the party hired out the space for a private event: “All visitors pay for meeting space in Shine and we do not seek out, bid for, or otherwise host any political parties,” wrote managing director Dawn O'Keefe. The guestlist was not down to Shine, but to the Tory party.

The audience consisted of journalists and around 150 Tory activists, according to the Guardian. This was instead of employees from the 16 offices housed in the building. I have asked the Conservative Party for clarification of who was in the audience and whether it was invite-only and am awaiting its response.

Jeremy Corbyn accused May of “hiding from the public”, and local Labour MP Richard Burgon commented that, “like a medieval monarch, she simply briefly relocated her travelling court of admirers to town and then moved on without so much as a nod to the people she considers to be her lowly subjects”.

But it doesn’t look like the Tories’ painstaking stage-management is a fool-proof plan. Having uniform audiences of the party faithful on the campaign trail seems to be confusing the Prime Minister somewhat. During a visit to a (rather sparsely populated) factory in Clay Cross, Derbyshire, yesterday, she appeared to forget where exactly on the campaign trail she was:

The management of Corbyn’s campaign has also resulted in gaffes – but for opposite reasons. A slightly more chaotic approach has led to him facing the wrong way, with his back to the cameras.

Corbyn’s blunder is born out of his instinct to address the crowd rather than the cameras – May’s problem is the other way round. Both, however, seem far more comfortable talking to the party faithful, even if they are venturing out of safe seat territory.
