I was wondering if someone on Airforums bought it

The Hartwell's show up less frequently than the Keeler latches do, possibly once a year or so. Oddly enough there's another one on ebay right now

Hartwell latch

Now there is a 3D printer project

I have been doing some work projects with a company in Belgium that is 3D printing in aluminium. Itís pretty impressive as some complex structures can be printed.

That sounds pretty cool. I wonder how strong and durable the components are compared to something that is CNCíd out of aircraft aluminum?

The printers that Wayne has and I've ordered are supposed to be capable of doing brassfill and bronzefill. I hope to actually try one or both of those someday. I'm pretty sure that day is a LONG way's out though!

Can you post a picture of one of the aluminum prints?

The parts are actually impellers for powder feeders so need to be functional - the original impellers had too high a volumeteric sweep (ie moved too much powder) so I came up with a design to reduce the sweep volume. I should have taken some photos before I install them last week but I forgot/was in too big a rush. They have been using them continually since then with no issues and I got back out next week to see how they are holding up.

Because these are in a pharmaceutical production line I will have to replace with the same machined from 316SS (so far the 3D printers can only print in SS17-4PH) but it was a great way to test the concept worked.

These are the guys who made the parts (https://www.melotte.be/en/product-ty...metal-printing)

PS don't ask the cost, you don't want to know!...but they are at the heart of a $12M installation so I wasn't cutting corners!

Yep, cutting corners is usually a bad idea!

I find it amazing that 3D printers even work let alone create the parts that are being printed now. It will be interesting to see where the technology is 10 years from now.
