So far I've printed off a few prototypes and nothing else. I am open to suggestion for sensible things to print, though the materials are quite expensive, so a 1/10th scale model of the Titanic is not on the cards :-)

Robin,

Perfect one would be a smaller size Lotus Elise S1 accelerator pedal. Complete work of art and sure everyone would love one on their desk :D
Lotus use to sell wider sections of that extrusion as desk tidies. (geek faction) :oops:

Yep - always remember it from the Lotus Story VHS (oops showing my age), wondering if any breakers have got any for sale at a reasonable price?

If somebody has a 2D outline of the pedal extrusion I could give it a go ... won't be very pretty though as the material comes out yellowy/clear.

Father in law has a couple of extrusion types 3D printers. The first one he built himself from a threaded bar frame, spare motors/belts and an arduino plus the usual open source controller software and motor drivers. The second is a kit (Mendel 90, £600) which his local makerspace group bought together and assembled under his guidance. TBH, I think building, getting them to work and then calibration/improvement is more fun than actually printing things. I have no interest in buying a ready-made printer, especially as the latest commercial kits are really only starting to solve design problems we fixed a year ago, and there's still a list of dozens of improvements for the self-build mk2 that's on the cards (mostly around auto-re-calibration after transportation, rigidity, better, more even temp control which is important to the extruded filament type printers, and some software changes to smooth direction changes (configuring ramp-up/down on the motor control, and detecting and eliminating resonant frequencies somehow).

However, strength tests of printed parts are quite impressive, accuracy is plenty good enough for just about anything you'd use one for.

I've thought of a few one-off practical uses for the printers, but not enough to justify building my own at home yet, especially when I can just email sketchup models to my FIL and pick up the parts next time I see him. :)

I do lots of sonar images at work which are mostly viewed on a 2D chart where colour represents depth. For some of the wrecks, if they are nice, I can do point clouds, would it be possible to do a point cloud in a 3D printer? Just increase the point size until we have overlap or perhaps use a wireframe representation?

Be cool to map them virtually too so you could explore them from you desktop.

I read in this month Evo that Koenigsegg are 3d printing titanium parts due to the small volumes required. Imagine having one of those handy to start replicating parts on your car and driving weight down.

Sure - are you hoping for a solid block with a a frosted finish over the virtual surface (sort of like etching the pattern into the inside of a block of glass) or are you wanting to print an object that actually has the surface of your virtual sea bed?

Both are possible, but the actual sea bed representation would be easier to achieve due to the fact that the plastic material doesn't come out crystal clear and yellows over time.

I think the processing would be relatively straight forward; we would simply convert the XYZ coordinates of each point into a mesh of triangles, then clean up the mesh to eliminate any unprintable features.

If you can send me some data I'll see what I can do - ideally something cool like a submarine or boat wreck.

Cheers,
Robin

It's a work of art - would be nice to have on display somewhere 8)

There's a place on Belmont Street, Aberdeen that offers 3D printing. I don't really know anything about it though.
