I'm finishing up design modifications to my DMLS printed chamber: http://www.rocketmoonlighting.com/projects/printed-chamber
I am planning to have the latest version printed sometime in the next few weeks - there are a few minor tweaks and improvements over the original which worked quite well.
There is a significant price reduction per unit when ordering more than one part, so if people are interested, it makes sense to buy more than one. Depending on the number of units, the price could be around half what it costs to make a single part. The price would be in the very low 4 digit range.
If you're interested, per the specs on the website above, drop me an email (i n f o at rocketmoonlighting.com). If I get a few responses, I'll do some homework and send out an email with more details to those who expressed interest.
