[amsat-bb] Hamsat uses for a 3d printer?

Thanks to all who have replied, for your comments full of insight. 

It's clear to me that competence in 3D printing is significant if not essential to the future Hamsat-er, so at my local hackspace I am going to learn how to manage a 3D printer, and maybe even build one myself!

Hi Andy If you have a look at the current edition of Oscar News from AMSAT-UK, you'll see thatour team working on the payload for the ESEO satellite have used 3D printing to produce a model of the payload enclosure.I believe the original computer modelling used STEP files to generate all of the drawings and that these were thenadapted for use with the 3D printer.The final enclosure for the L band to VHF  FM transponder has to be milled from a solid block. As we didn'twant to do that job twice (250 x 100 x 50mm and expensive) it made perfect sense to produce one with 3D printingto ensure that all the mountings and cut-outs were in the correct position. Thanks David  G0MRF     -----Original Message-----

Hi I am thinking of investing in a 3D printer or using one at our local 
makespace. Here in the UK a magazine is offering a weekly build-by-component 
series to make a 3d printer that will run on a pc or mac and uses DOT stl files 
for the design. A lsow build but an interesting idea nonetheless. I have seen at 
ESTEC 3d printed model plastic cubesats and am aware of the experiment on the 
ISS but do not know the software used or data file format. I was wondering if 
anyone on the -bb has experience of using a 3D printer for outreach or (like 
SATNOGS) for building rotator gears, and if so whether the file extension DOTstl 
is an industry standard for this work? I wonder if the estec and nasa files 
would be reachable by, say, the freedom of information legislation, or would be 
handed over. many thanks 73 de andy g0sfj
