Enable - a metal printing firm, ran a competition where you had to guesstimate the weight of the same part printed in: steel, aluminium and magnesium.

There were 50 really fancy looking 3d printed metal pens for the 50 closest guesses over the three days of the tct show.

Got a text this morning - I've won one :-)

So based on that, the steel part was around 9kg, the aluminium one around 2.5kg and the magnesium one around 1.5kg.

Who says fishermen always exaggerate the weight of their catch, I was obviously pretty close ;-)

I'll post a pic of the pen when it arrives - I didn't take any pics at the show, but they were pretty fancy looking things with lots of intricate cutouts and wibbly bits. (it's a technical term)

I can't find enable listed as an exhibitor - so they were probably a last minute decision.

So that's pretty cool :-)
