You are still over selling it.  It can not be used to build a rocket engine.

A thruster is not a rocket engine

ahhh,  your talking "Additive Manufacturing" for a completed part.   The term is not fully defined atm and can in some cases be used interchangeably with "3D Printing"

My posts outside of this thread refers to the use of "3D Printing".   A wide set of "new tools" to manufacture rocket "parts", assembly required  :D

this video explains just one of the new wide set of "new tools"




The rest falls under "Proprietary"

Good News for Concert Halls and Submarines: Duke Engineers Demonstrate 3D Printed Acoustic Cloaking

http://tinyurl.com/qjh6aew

"The repeated holes in the 3D printed sheet material, layered on top of each layer forms a pyramid structure. Essentially, the cloak alters the trajectory of the sound waves to give the impression that they do not hit anything and simply progress as if an object were not in the way. While the end result looks elegantly simple, the effort and brain-racking proved arduous."



Published on Mar 11, 2014 


This video demonstrates the difference in how sound waves act with and without the acoustic cloak in their path. The red and blue lines represent the high and low points of the sound waves. As they return to the top of the frame, notice how the profile of the sound waves on the left with nothing in their way closely matches the profile on the right after interacting with the acoustic cloak. In contrast, the center trial shows the deformation of sound waves that occurs with an uncloaked sphere in their path.

Research At Cranfield Yields Large Scale 3D Printing Metal Process (UK)

http://tinyurl.com/nvmgv7q

"constructed from titanium utilizing Cranfield’s proprietary Wire+Arc Additive Manufacture (WAAM) process. Spar sections are critical structural parts within an aircraft wing, and using the WAAM process, this metal prototype took just 37 hours to construct, direct from a digital model. By comparison, using traditional manufacturing methods, the same part would typically take weeks."

Chinese Rocket 3D-Printed Seats

"Since 1998 Professor Cui Guoqi, director of the Rapid Prototyping Research Center in Tianjin University, has been creating 3D printed seats for Chinese space missions."

 “During launch and landing these specially designed seats… protect the astronauts, especially their backbones, from being hurt by the jolt during acceleration. Every seat [is] tested by the astronaut in person and undergo[es] adjustments to make it more precise.”

Most of the DIY and driving force for 3D Printers comes out of the Reprap "open source" http://reprap.org/wiki/RepRap

===============================================
MoonBase Parts printer anyone?

This Reprap printer was enlarged:  The World’s “First” 3D-Printed House Begins Construction
http://tinyurl.com/kdgov22

"the actual 3D printing of the components for the “first” 3D printed house."

KamerMaker XL, a 3.5 m tall FFF printer, made its way to the Buiksloter Canal in Amsterdam on January 6, where it’s already begun printing. The printer, more or less a large RepRap housed in a shipping container, is using a type of plastic — an 80% bio-based hotmelt, developed by German chemical company Henkel — to print pieces that will be assembled into a complete house.

Another new Toolset

Soluble Support Material Supports Creation of Hollow Composite Parts

http://tinyurl.com/pr2855k

"if you’re just familiar with composite manufacturing, you’ll know that composite parts are made by laying down or wrapping composite materials and resin over moulds, patterns, cores and mandrels. Producing hollow composite parts is a difficult challenge, dealt with by forming two halves of an object in a mould, joining the halves, and cutting away excess material.  With soluble support materials, however, it’s possible to create the soluble skeleton for an object that can be wrapped in composite material and rinsed away, leaving a hollow part."

Possible new Space Medical uses?
================================

Two stories


EOS Releases Two Medical Grade Materials for 3D Metal Printing
http://tinyurl.com/qay7jfe

"new EOS Titanium Ti64ELI and EOS StainlessSteel 316L materials, the company will be able to 3D print new medical-grade metal parts."

"EOS Titanium Ti64ELI is a light metal alloy that is both corrosion resistant and biocompatible.  Conforming to the chemical composition and mechanical property standards of ASTM F136, meaning that the alloy, with its high grade of purity, is suitable for 3D printing medical implants. "

===============================

3D Printing Saves Face in Life Altering Reconstructive Surgery
http://tinyurl.com/phvh5n6

"Such surgeries include that of their recent patient, Stephen Power.  Power, 29, received multiple trauma injuries in his 2012 accident, breaking his top jaw, nose and cheekbones and fracturing his skull. Improvements in 3D printing have made it possible for Sugar to have custom prints made from Power’s CT scan, both for implant and to create surgical guides. By scanning their patient’s skull, they were able to reestablish the symmetry Power lost after the accident, printing a symmetrical 3D model of his skull."

Example of using a $2000 dollar off the shelf 3D Printer to fix a problem.

Hospital Technician Tethers Cables & Saves Hospital Money with 3D Printing



https://www.youtube.com/watch_fragments_ajax?v=twP4aX2sd8c&tr=time&frags=guide

Uploaded on Mar 18, 2014 
Steven Jaworski, a biomedical technician, had to replace so many cables that monitor patients' vital signs that he ordered cable tethers from a medical supplier for $24.50 per cable, or $73.50 for a set of three. But surgical scissors cut through these tethers easily.

Then Jaworski appealed to the Brookhaven administration that a MakerBot Replicator 2 Desktop 3D Printer could help solve his cable problem. He designed a tamperproof cable tether. Between the dense black PLA and thick wire, it costs $7.94. It holds all three cables, and surgical scissors can't cut through it.

How NASA brought the monstrous F-1 “moon rocket” engine back to life
The story of young engineers who resurrected an engine nearly twice their age.

http://arstechnica.com/science/2013/04/how-nasa-brought-the-monstrous-f-1-moon-rocket-back-to-life/3/

"Each Pyrios booster will feature a pair of F-1B engines, built with techniques that more resemble 3D printing than traditional casting or milling. The main combustion chamber and nozzle in particular will undergo tremendous simplification and consolidating; the parts count for those two assemblies together will be reduced from 5,600 manufactured elements in the original F-1 down to just 40."

"are using techniques like selective laser melting and hot isostatic pressing (HIP) to "grow" entire complex engine parts out of metal powders. "

Yes and NO

http://reprap.org/wiki/RepRap

"RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. We are using 3D printing to do this, but if you have other technologies that can copy themselves and that can be made freely available to all, then this is the place for you too"

Been a major driver for new innovations in the 3D Market under an "open source" model.  Sadly, many have taken the ideas and developed the designs into commercial products to make money.  The ideal of making 90-100 percent of the parts has gotten lost in the process.

Yeah, but this is a great strength of the open-source model: I can and has sprouted all sorts of commercial spin-offs. The amount of value created by the RepRap project indirectly by all these countless 3d printing start-ups is vast, probably in the billions of dollars (Makerbot--started by one of the founders of the Reprap community--alone was bought-out with a valuation of over $400 million and an additional $200 million in other value).

I agree, though, that it's important for the Reprap project to continue. I think they could be pretty close to building some of the major components with another 3d printer (including the stepper motors and xyz stages), though no one has put in the energy to do it (it wouldn't be as practical as buying conventional stepper motors and such). Also, progress is being made with circuits and the like.

My guess is that eventually someone will be able to print a 3d printer with almost entirely another 3d printer, but it'll take a lot of assembly and hard work.
