Does anyone use a 3-D printer? I am looking at a MakeGear M2.

Re: 3-D Printers
It seems like it would be good for mounts and objects.
Re: 3-D Printers
They are getting better but still are expensive and you might have to play much to get consistent results.
I like more to use Internet 3d printing service, as you are more flexible in material, size and so on. And they are not really expensive. So you can make dozens of models for the price of a own printer.

Tony Coleman used a 3-D printer for his object for his hologram for the (in)famous Holo Forum pass around box, which seems like an ideal application for those units. And it would be a blur the distinction between analog and digital holography.
BTW, did the contents of the pass around ever make it back to the original owners?

Collin,
As for printers, the problem is you are dealing with plastics (ABS/PLA)/resins, which do not have the best mechanical or thermical properties for estability under stress or temperature variations.
However, this is a path I'd like to explore. There are a handful of pre-designed parametric mounts you can explore:

http://www.thingiverse.com/thing:38062 (lens holder)
http://www.thingiverse.com/thing:30727 (kinematic mount),
Anything in thingiverse that you can find searching for "Open-source optics project":http://www.thingiverse.com/search/page: ... ct%2C+&sa=

Re: 3-D Printers
Colin,
We thought about it. But, as Arturo points out, the mechanical and thermal stability is a problem. However, when I heard that the resolution of some of these printers, using photopolymers, can get down to 16 microns, that peaked my interest. At 16 microns, a HeNe beam will deviate about 2 degrees. So, if you built a wheel with sectors intermixed with these 16 micron structures going both ways, you have a scanner over 4 degrees, or roughly over a barcode.

Re: 3-D Printers
So anyone tried to print some of these holders and found them unusable? Even with longer settling time?

Re: 3-D Printers
I am very slowly building a work space. Thank you for the replies. Hopefully this year I will see laser light again.
