I love that this will be greenlit 38 minutes after it is over.
 
2014-05-29 09:58:42 PM
Oh wow.. this is scheduled for 2 hours? Nevermind.
 
2014-05-29 10:32:15 PM
It's manned by dragons? Dude, I really haven't been paying attention to the news enough lately.

A printed rocket engine?

/GO SPACEX!

I just love this stuff.

MaudlinMutantMollusk: A printed rocket engine?


from what I have heard, they have a LARGE 3d printer that does metal
 
2014-05-29 10:40:36 PM
Ok, so we've got 7 astronauts in a can designed to soft land under thrusters (on little legs). A flip top lid covering the docking port. 3d printed super draco thrusters for that soft landing. Which, if they're powerful enough to do a soft landing they're powerful enough to push the capsule away in a launch escape situation. They're also redundant, can lose 2 super dracos and still soft land. There are 8 of them. Backup parachutes if needed. Carbon fiber wrapped titanium fuel and pressure tanks.

And yet, the most interesting thing was that the service trunk has fins on it. Anyone know why?

I got a brief ten-second pic of the ship, and then a SpaceX starfield that won't go away.

Most likely they're using DMLS (Direct Metal Laser Sintering).  It is starting to get more common, particularly in aerospace.  It gets called "Additive Manufacturing" rather than 3D printing, though.

I like how the interior is like one of Elon's Tesla cars.   It looks and feels like a sci-fi movie prop, DAMN, this thing seems futuristically advanced.

Abstract

This paper presents the mechanical and gas barrier properties of titanium alloy foil-inserted carbon fiber/epoxy composites (CFRPs) undertaken to improve gas barrier properties for cryogenic propellant tank applications. A newly developed β-titanium alloy (GumMetal, GM) was applied. A sheet of titanium foil (α-Ti or GM, 0.05 or 0.1mm) was inserted between cross-plied composite laminates ([0°2/90°2]S) without adhesive. Epoxy resin in the prepreg contributes to bonding between the Ti-foil and CFRP. The Ti-alloy foil insert did not strongly affect the tensile or compressive strength. Transverse cracks in the 90° layer never penetrated into the Ti-alloy foil layer before the final failure under tensile loading. Nonlinear stress-strain behaviors attributable to the pseudo-elastic behaviors of both unidirectional CFRP and β-Ti alloy (GM) were estimated using high-order stiffness and classical lamina theory. The numerical results agreed with the experimentally obtained results. Helium gas leakage under tensile stress was not observed before the final failure of the composites (1.4% of tensile strain). The excellent mechanical and gas barrier properties were successfully demonstrated.

Branson is pissed off tonight, I reckon, even though his SS 2  passed another milestone this week.  Dragon 2 makes SS2 look like relatively weak sauce.

Technically, at least with current metal additive machining methods, it is stereolithography. It's a cool technology to be sure, but "printing" assumes the material is being deposited. Stereolithography and DLP are a bit different, the material is already there. It's being fused into usable "slices".

/am currently the go guy to on a DLP machine at me new company.
