3D Printer for work, under £10,000

[curious aardvark]

if you can get a polyjet for under £10,000 I'd be surprised.

Also do the materials support to a high enough temperature for injection moulding ?

Your best bet is most likely a hyrel with hi-temp extruder and look at printing with something like PEEK.

So you'll need both a heated enclosure and an all metal hi temperature extruder.

The new fusion looks like a major improvement over the original fusion printer. Worth a look.
There are a number of uk companies selling machines - so worth talking to them first.

Oh - almost forgot, my absolutely favourite machine from last years tct show - leapfrog bolt !
Has dual INDEPENDANT extruders. So you can print two things at once, or copies, or use soluble supports etc. Plus has hi-temp option up to 360c, is fully enclosed and looks amazing :-)

Get that !

That said the hyrel also has multiple extruder options. Not independant (yet) - but you can have at least 4 heads running at the same time.

But if i had the money, I'd get the Bolt. Just fell in love with that machine.
Alas davo and hyrel have yet to make it to a uk exhibition, so i haven't had the chance to hug a Hyrel yet lol

These guys have one of the biggest printer stocks in the uk: https://www.technologyoutlet.co.uk/
They also sell leapfrog machines, so could possibly save on import tax etc.
