Henning:
On the subject of printing gaskets, I would say that is entirely possible. I am experimenting with a material called cheetah which is a thermoplastic elastomer. A quick google will probably bring up the relevant tecspec for anyone interested. I do believe this would be a suitable material for gaskets in low pressure and low temperature cases. I have not printed any gaskets in it yet, but I did make an elastic cover for my iPhone which worked out pretty good.

This one?

Thank you....So far I haven't seen too much use domestic 3D printers, but printing elastomer, structural plastics and possibly some (slide) bearing material would expand a whole lot use. Specially if I could fabricate/mill/turn part in aluminium and then "print" gasket and/or cover into it.

Henning, that sounds interesting and useful stuff. Is it an 'exotic' requiring pretty special printing requirements, or are we just talking heated bed and suitable nozzle temperature ?
Henning:
As I understand it, printing on or into existing parts is still not very easy with the regular "home gamer" machines. I do think it will probably be introduced at some point though. Probably not until the materials get better though. I have a spool of Nylon with which I intend to try and print some parts. If that works out ok, I'd say we're closing in on game changing technology!

I did some search and fast reading on thermoset elastic filaments to 3D printers and they seem to be available, they seem to work on same envelope than ABS. PLA-only printers does not seem to work them.
Biger obstacle to me is the SW side. I'm slow learner, but when I learn something it comes hardwired and almost automatic. CAD is another thing altogether, but slicer is the part that feel iffy.
How can print elastomer (ar any other stuff) over prefabricated part? Can slicer be used to sellectively start printing at certain "height" or can you set and tweak height contour?
Printter table should ofcourse be able to support the part like aluminium light weight eclosure.
Probably faster approach would be to print alastomer on PA or ABS part or carrier/sandwich and accomondate that into design.
