The printed Motor parts are all here, I have a few things to finish and it will be ready to run.
I made the tubes for the fuel input too short and connecting to them is going to take some creativity. The end cap with o-ring grove, clearance for flow and fingers to push down on the cat pack turned out well:

I've sent out the order to get the catalyst retainers water jet cut.
All the bits and pieces should be here by mid month. If I will decide to brave FAR/Mojave in peak summer is a different question. There is a real possibility it won't get tested till mid to late September. Business continues to go reasonably well, this means that I should be able to ramp up my rocketry projects after the first of the year.

That's very cool Paul! Thanks.
What is the price tag for this?

Which vendor is doing the printer? And which material have you selected?
Cost not including welding is around $450.
Bruno,
Take a look at www.shapeways.com
They do Stainless steel infused with bronze for $10.00 per deposited CC.
I think it is really cool that you are pursuing the printing angle, it is fascinating. I really look forward to the postings you are doing on it. Keep up the good work.
Just out of curiosity. How did you weld it (TIG,...) and what kind of material did you use for welding (bronze or stainless)?
You are doing interesting stuff. Good luck with it!
Welded with TIG using stainless rod.
Cool stuff, that.
I get email from shapeways all the time wanting me to print a vase or a picture frame. Seems like printing a rocket motor would be much more fun.
As always, thanks for dragging us along for the ride!
I have had some parts of the same material printed by Shapeways. Very interesting. I found the material to be much more brittle than regular Stainless.
I talked to a representative of a UK based company yesterday during my Farnborough air show visit. What they do with laser sintering is just amazing! Turbine blades or stators with integrated cooling channels of 0.2 mm or printed fine meshes made of Titanium for medical applications etc...

To create or to modify a motor is not easy, however there are persons with neccesary skills to do it, and I'm sure you are one of them.
so extremely cool =)
