Stratasys

[Miguel]

Hi Chris,

May I get trained to used the Stratasys?  Got some printing to do.

Regards,

Miguel

Hey, just to let everyone know, the stratasys is 'locked down'. This is due to the fact that it is impossible to find replacement parts and if they can be found will be in the thousands of pounds range. If people would like something printed on the stratasys send me an email with the .stl file (other formats accepted but will need resizing in conversion) and i will reply with a quote.

As it stands, for each cubi cm of material it is 35p and each hour is 25p.

Regards
Hipster

May have a job for you. Not sure yet but it'll be billed to me / Leeds Uni. Its a model of a human colon :P

Perhaps we should learn what we can from it and work on a new printer?
Something with the capabilities of the Stratasys but the open source
nature of the reprap?

If we could get that long-sidelined CNC conversion of the mill done,
then we'd be a bit less reliant on skilled hand-engineers for making
more durable parts such a system would require.

Do we have an RTS-style tech-tree diagram yet? Upgraded 3D printer, plus
a plastic recycler has to be at least a -70% modifier on unit production
cost.

For plastic recycling, we have an injection moulding jig which can
generate printable filament. It requires a small granule size for the
source plastic.

We also have a mincer that can be used to chop larger pieces of
plastic into small pieces. It just needs some new bearings and a more
effective source of torque.

We've got three lathes at the hackspace already, but i'm going to make
a fourth, using one of the designs from thingiverse,
http://www.thingiverse.com/thing:9242

The one thing the reprap can't currently do, is print the major
structural components, the threaded rods. Either a screw-cutting
devices like one of Maudsley's, or a simple lathe would solve this
problem. Tweaking the design to be strong enough to work materials
that could be used for the structural supports will be fun.

I have a 3-wide chain and sprocket set from a Harley Davidson that
should do about a 2:1 reduction and increase torque if you have a decent
motor? Only ones I have spare are about 350Watt.

If you need any ground stainless rods for your mini-lathe, I have a lot
from printers as well a few brass bushings that may fit. Maybe in
exchange help me get my first 3D parts made?

Also have the guts of an old shredder to hand. Wanted to make it reverse
feed when blades slowed so it could "chew" up platics it couldn't take
in one pass.

Also should note a 4-axis mill would be able to make threaded rods.
