I was told that the PVS-14 30mm eyepiece and the ANVIS eyepiece are the same except that the PVS-14 eyepiece has the threaded inner ring for the eyecup whereas the ANVIS does not.
The coatings on the ANVIS objective lense are supposed to reduce green cockpit glare... and they are a full turn for focusing vs. 1/2 a turn for the PVS-14 objective lens. I am sure others will have more information. G. |

there are a few different anvis eyepiece types.
There's this one: 
and this. 
They don't take the same parts, because I'm currently sitting on 2 lens cells for #2, that I was hoping would fit in #1. #2 looks like the same setup as a PVS-14 eyepiece. I know when I've torn them down, I've come across lenses where the inside of the lenses isn't always the same either, so there is likely more variances, as well. |

Yeah, there are actually like 4 or 5 different kinds, I've read a thread about that in the archive I think...
My PVS-14 Pitbull has an eyepiece just like #2, with a thread inside the lens ring for screwing the rubber eyecup. I think the #1 one is from an older device (I think AVS-6). The new style for ANVIS and PVS-14 is 30mm AFAIK. G. |

Or a fully printable ocular lens, with threads the same as the objective ( doesn't take much to work out that has a few uses ) - And takes COTS astronomy lenses for different purposes.  Regards David

General estimates are that printed parts are about 1/2 as strong as injection moulded parts, which is plenty when you consider what that means, and you can always add structural mass since it's very light anyway. I use a PP3DP UP! Mini, and black ABS, with CorelCAD for designwork - Regards David |

is the pp3dp mini good enough for your needs, or would the Plus 2 be better suited, since it is a higher resolution, albeit at 2x the price.
I was also looking at XYZ's DiVinci 1.0 http://www.amazon.com/XYZprinting-Da-Vinci-1-0-Printer/dp/B00H7VEU0G/ref=lp_6066127011_1_1?s=industrial&ie=UTF8&qid=1418833349&sr=1-1 Are you happy with your setup? |

oh jeez, thanks...
guess what I walked out of Home Depot with today. lol. 
It'll print 100 Micron resolution. $999. $25 bucks a spool. It is a rebadged flashforge, but the support comes from AutoDesk, Dremel/Bosch. Is there any place that has the 3d cad drawings of the pvs parts? I wanted to print up some eyepiece parts, tube retention rings, etc. :-) |

What do you think is the best printer in the $5,000 - $7500 range? From what I understand, it's a balance between speed, quality / fine detail ability, project size, and material handling ability. I'd like to be able to print at least 305mm (12-inches) in all three axis with probably a maximum layer thickness of 0.02mm at a minimum of 150mm/s, at least two (2) heads and would be able to handle all 6-7 of the popular materials. Any thoughts? |

You would still need the drawings and software for what you wish to make. I picked up the cheaper version, because I just plan to prototype my designs, and I'll likely still send stuff off to places like http://www.shapeways.com/
I'm not sure how the 5k versions compare, other than giving you a much larger design platform. I'm still not sure I made the better choice, because David's printer was much more economical. I just wanted the 30 day in store return policy through Home Depot to make sure the technology works for me and that the unit is up to par with my needs. |

Apologies to the OP for hijacking the thread, but since the OP has joined in, I'll take that as an endorsement - Horta - an important question is what kind of modelling are you looking at? FDM ( Fused Deposition Modelling ) has limits on the Z-axis and I don't think anything past around 50 micron is all that practical at the moment, also even once you look past technical limitations, there are questions such as how the unit puts together the models, what you're using it for, etc. If you're looking at higher resolutions, SLS or laser-hardened resin systems might be more practical depending on application - I am pushing the limits of 200 micron technology with a 1mm thread ( five layers/thread ) and this may not be improved at lower resolutions - I've yet to see any detailed fine prints that qualify - One thing is certain, we're only touching the very beginning of what 3D printers will do for NV - Future upgrades will be very commonly disseminated through files, though in this sense, ITAR is more of a problem than with physical items, as files posted to the Internet are considered as exports under ITAR.

You're good - I've adjusted the title. Its okay that the thread went a little off course. I guess nobody cared about optics anyhow. lol.
With you being much more versed in ITAR than I am, do you know what can and can't be shared within the realm of ITAR - at least from an AU perspective? Is the entire design of anything 3rd gen off limits, or are things like lenses, and empty battery housings free game? Like you, I also want to make sure I don't violate ITAR if I get into this, but I'd also like to start posting my drawings so the open source community can improve upon them - as that is the spirit of innovation. What if I build my own custom housing to hold dual MX-10160 tubes, that is threaded for PVS-14 Objectives, and eyepieces - will my design also be subject to ITAR restrictions and not freely sharable or open to discussion on the public domain? |

can't print the electronics, so either way, there will be some custom fab work.

yeah, but think of it.....a pair of Gen2 D300's from eBay and a custom ANVIS style housing that fits the internals of the D300's would be relatively inexpensive and should work pretty well. Or if you made the custom ANVIS housing to fit PVS-14 internals that would be extremely nice.

I am talking about just a twin j arm thing kind of like the nightvision depot setup. You could then cannibalise a j arm for the clip.

Trying to predict ITAR is like trying to nail jelly to a tree. About the only real way to be certain is to request an technical evaluation - In my case, it's all done under treaty and the details are specified by the US State Dept, so I imagine that ITAR is very similar here and in the US, except we don't call it ITAR here, we call it defence trade controls ( and the USML we "rebadge" as the DSGL ) - so if something is controlled in Australia, it's automatically controlled in the US, and vice versa. I guess it's possible that something could be controlled in one country and not the other, but I'd imagine that a part in Australia which is determined as not controlled could reasonably be trusted to be not-controlled in the US also. Anyway, I don't try to guess, I send in the paperwork to defence and they have analysts who compare my request to the US requirements and then either tell me it's not controlled, or send me permits as required. Generally a very helpful bunch, and nice guys to deal with. As for posting the stuff to the Internet? A good question - that's what got Cody Wilson ( 3d Printed Gun guy - defence distributed, etc ) in hot water - He got caught out for posting the stuff to the Internet, and the files were deemed "controlled" - and it was pretty obvious they were going to do that to begin with, so if he foresaw that, he would have made a request to the PMDDTC for a technical evaluation before he started talking about the products - posting photo's is fine, but since a 3D file lets you build something, that's a different matter - Of course, I have no idea what the PMDDTC charge for the service in the US - It's probably fairly expensive in Australia, but the government is footing the bill for me, so I can operate as a smaller manufacturer. They do have a "sharing" group - it's called "defence community" but things can't be shared publicly. Yeah, it does kind of destroy innovation somewhat - :( Regards David

I was bummed about not having dual print heads, so I ran over to micro center today and picked up a PowerSpec 3D Pro Printer - which is a clone of Flashforges Creator Pro / Makerbot. It is less locked down than the dremel, and handles more media types. It is on sale for $799 until the end of the month. Some minor assembly required.
The dremel unit is a really well put together package, and the instructions are top notch. I just don't like that it can't print support material using a filament that dissolves. I figure I'll run both and see which one prints better. I ran into some issues with the Dremel printing some of its clear media, so I was debating on returning it for that reason. I wanted clear so I can print my own light pipes.
