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.

How the Lib Dems learned to love all-women shortlists

Yes, the sitting Lib Dem MPs are mostly white, middle-aged middle class men. But the party's not taking any chances. 

I can’t tell you who’ll be the Lib Dem candidate in Southport on 8 June, but I do know one thing about them. As they’re replacing a sitting Lib Dem (John Pugh is retiring) - they’ll be female.

The same is true in many of our top 20 target seats, including places like Lewes (Kelly-Marie Blundell), Yeovil (Daisy Benson), Thornbury and Yate (Clare Young), and Sutton and Cheam (Amna Ahmad). There was air punching in Lib Dem offices all over the country on Tuesday when it was announced Jo Swinson was standing again in East Dunbartonshire.

And while every current Lib Dem constituency MP will get showered with love and attention in the campaign, one will get rather more attention than most - it’s no coincidence that Tim Farron’s first stop of the campaign was in Richmond Park, standing side by side with Sarah Olney.

How so?

Because the party membership took a long look at itself after the 2015 election - and a rather longer look at the eight white, middle-aged middle class men (sorry chaps) who now formed the Parliamentary party and said - "we’ve really got to sort this out".

And so after decades of prevarication, we put a policy in place to deliberately increase the diversity of candidates.

Quietly, over the last two years, the Liberal Democrats have been putting candidates into place in key target constituencies . There were more than 300 in total before this week’s general election call, and many of them have been there for a year or more. And they’ve been selected under new procedures adopted at Lib Dem Spring Conference in 2016, designed to deliberately promote the diversity of candidates in winnable seats

This includes mandating all-women shortlists when selecting candidates who are replacing sitting MPs, similar rules in our strongest electoral regions. In our top 10 per cent of constituencies, there is a requirement that at least two candidates are shortlisted from underrepresented groups on every list. We became the first party to reserve spaces on the shortlists of winnable seats for underrepresented candidates including women, BAME, LGBT+ and disabled candidates

It’s not going to be perfect - the hugely welcome return of Lib Dem grandees like Vince Cable, Ed Davey and Julian Huppert to their old stomping grounds will strengthen the party but not our gender imbalance. But excluding those former MPs coming back to the fray, every top 20 target constituency bar one has to date selected a female candidate.

Equality (together with liberty and community) is one of the three key values framed in the preamble to the Lib Dem constitution. It’s a relief that after this election, the Liberal Democratic party in the Commons will reflect that aspiration rather better than it has done in the past.
