This is a link post For those of you who 3D print stuff
things are moving faster

This is a normal post that was excellent

This is a normal post Initially I thought it was a timelapse
like most other 3D print videos.

Then I saw the live clock counting seconds.

Which I thought was minutes.

Then I genuinely realized it was in real time.

Of course quality is not awesome, but it's good for just making a very quick prototype if you just want to get an idea of what it's like.

This is a normal post why is there only one print head? Is it by necessity?

This is a normal post Not sure
some have more than one type of filament installed at a time but I don't have one of those so I can't say how they work.

From a quick google they have more than one extruder so you can print each type individually or mix them up.

To give you an idea of how quick this is, normally the little benchmark boat takes about an hour to print.

This is a normal post Yeah, multiple extruders are so you don't have to change filament part way through a print, so you can use different materials or colours
but the extruders are not usually used at the same time, and on cheaper machines they are mounted on the same print head.

This is a normal post There are multi-headed 3D printers, but they're usually for printing large items.
They're not really practical for a small item like this as they'd get in each other's way.

This is a normal post I can imagine the material being deposited creates a limiting factor or at the very least an unwieldy print head
unless you could deliver the material faster with a multidirectional nozzle in a controlled manner.

This is a normal post I read an article about that recently
www.imeche.org/news/news-article/morphing-3d-printer-nozzle-enables-complex-new-creations
Presumably still in experimental stages at the moment. Of course, "The team is also in discussions with the US Department of Defence about using the morphing nozzle to support the production of weapons" because obviously that's the priority.

This is a normal post Depends on whether it would reduce costs and overhead for the department of defense.
Then they could reduce their budget*

*for weapons, while increasing the budget for weapon making machines and companies by a higher amount
