jjsmith77,

Please don't see this as a desire to start a huge pissing contest.
I am a stockholder/long and am very pro SGLB.

I give you an example, GE plans to print 40,000 nozzles by year 2020. This is approximate 8000 nozzles / year (40,00/5).

The time spent to print (1) test piece at EWI was 194 hours. Page 26: http://marketing.ewi.org/acton/attachment/12956/u-0003/0/-/-/-/-/

Let's say this test piece is GE's nozzle.

1 part = 8 days (194 / 24 = 8.08)

365 / 8 = 45.625 parts/year/machine

8,000 nozzles / 45 parts = 177.78 machines needed for a goal of 40,000 nozzles.

Here's my 2cents worth.
1: The test coupon they produced in Nickel was 3x2.6x0.5 inches. A massive 3.9 cubic inches of solid metal! Hence the reason for the 196 hr. build time. These fuel nozzles are tiny by comparison and mostly a shell to allow passages for the fuel. Bottom line for me is the AM build time per fuel nozzle is significantly less.

2:Per Sigmas own web site INSPECT is currently an in process monitoring and data collection system. It captures machine operating parameters as well as part build data at the same time and produces a report of actionable data to fine tune the process going forward. That report gives the manufacturing engineer the info to weed out suspect parts without the need for 100% post AM inspection.

P.S I really enjoy the great discussion on this board.It's a breath of fresh air compared to the rest of IHUB.
