Something new people. Four weeks ago I ask Michael (keymichael1855) why do you try not design a 3D Apollo SM LM Reaction Control System (RCS) and in scale 1:1. He say why not, day after that he had it ready. I order in The Netherlands and this morning I receive it. After 7 hours hobby, painting what cables, wires it was all ready. Only did not has the Marquardt Corporation logo type plate logos. I'm not sure if I may use them on a fake RCS, but for less, a collector have now a very real Holy Grail (more photos).

This is quite impressive Pascal and Michael! From one of the photos, I can see Historic Space Systems' website was used as a reference, too. This has me thinking about what other comparatively-scaled hardware (desktop size at 1:1) could also be made in similar fashion. |

That's really neat.As Robert said, this really opens the door to many possibilities. |

That's impressive.Michael Key has hit another one straight out the park with that design. I can't think of a more recognisable part from Apollo at 1:1 scale that looks so good and will still fit inside your home! I want one! |

Okay, this is nice. But I'm starting to think I should plan on offering a competing product. It will take me a while, though. |

You'll do in metal? It would be perfect!
I talk about non-functional models and without components. Only mokup model... |

Won't be to long before it will be possible to 3D print an actual R-4D. Some components of other bi-propellant rocket engines already are being produced via 3D printing. The ability to digitally disseminate the specifications to the point at which precise renderings of actual hardware can be achieved is going to be another challenge for the export control/counter-proliferation folks. |

I got yesterday late a mail from Michael (keymichael1855) with the Marquardt Corporation logo type plate logos, they look very real, have the model now final complete. Two extra wires above on two heads and give the engine bell below a little more touch burn gold. I have dammage a little the red and green Corporation logos, to let it look a little older. So it looks much realer I find (more photos)

Under U.S. international trade regimes, technology which can be adapted to weapons systems may not be exported without government approval. The restrictions apply not only to the technology itself but also the information which enables a foreign recipient to replicate or accelerate development of an analog capability. Reduction of a design to digital code makes it more difficult for authorities to regulate transfer (proliferation) of this information to restricted (non-US citizen) recipients. |

Hey Pascal, that looks incredible!!! To see it go from my computer screen to the finished physical product is absolutely amazing. You did a fantastic job with it! The labels really added a nice finishing touch to bring it to life- I'm glad that you were able to incorporate those. Very nicely done. Thanks to everyone for the compliments. As always, it was a fun project working with Pascal. Robert, I am looking to produce other full/large scale models in the near future, so keep an eye out for those. Thanks! --Michael |

If replicate an RCS is so dangerous... because the NASA and astronauts endorse my work of popular science? I replicated the Lunar Rover, the Command Module, space suits, and more and it seems that it is useful for the youth of today to see as we went to the moon without digital technology. I understand your point of view, but we must give proper proportions to the thing. We are talking about a model absolutely obsolete, superseded. We are talking about a toy resin that can be replicated anywhere in the world. Well done to Michael and Pascal. |

I think Scott is just noting that the advance of 3D modeling technology will one day, probably some years from now, make it very difficult to control the export of sensitive items. There is no problem with the export of this model in digital or physical form. |

I do not think that 3D technology (now in existence for many years all over the world) is a problem. You may not know that export the technology is very easy, because there are your fellow countrymen who sell abroad. Everything is for sale in this world. I close here because the situation is complex and has nothing to do with the plastic models. |

Luigi I do believe that you misunderstood Scott, he wasn't implying the export of this model would be subject to the export laws, I do believe he was referring to the real hardware. |

Thank you, I understood, but here we are talking of the replicas in plastic... and not of the actual hardware. However, even the real hardware is all over the world, including Italy. But I do not think we're going to the moon very soon!  |

Too bad Shapeways' service is still so expensive. $355 to print these parts. Hopefully the cost will come down as they have more competitors. |

The material cost on these types of machines is high and will probably be that way for some time. Given the size of these parts I'm not surprised at the price. |

Just how much does the powdered plastic material that these laser sintering machines use cost? Does anyone know? I have a MakerBot Replicator 2 printer, which is a fused deposition modeling (FDM) printer that uses spools of PLA plastic filament costing about $35-$40 per kilogram. Unfortunately these home FDM machines, while fun, are not capable of the resolution and finish of Shapeways' industrial machines. |

Example of a functional printed thrust chamber produced in Shapeway's sintered stainless steel undergoing test firing. Production cost less then 2K. |

We have a Objet printer at work. Per kilo plastic cost is close to 10 times what you mention, and service costs are several thousand dollars per year. High quality 3D printing is still very expensive. |

Thanks, Brian. Hopefully the materials cost will fall rapidly as adoption of the technology increases. One day you will be able to customize and print out your plastic model kits at home. |

While waiting for the cost of 3D printing to come down, would it be feasible for a popular kit like this to be recast in resin? (Only one 3D model need be printed and this could then be used to make resin molds). |

I had a busy week to build some RCS quad for a few cS members, each day from of Monday I put one togetter paint and well. Tomorrow they got all three a plug set and they are done and they will be shipping over the globe. Next one will be a full RCS house with four quads, scale 1/2, in little cutaway.

The printing cost only for the 1/1 qaud RCS are euro 384. For the qaud house with 4 RCS, 1/2 euro 550 (only printing). |

In the photo of the quad there does not seem to be enough room inside the box shape to hold the tops of all 4 engines. What am I missing? |

That is right Gary, the quad house will be comme in the frame and the RCS thrusters will come a get a little out of the frame.I receive tomorrow the quad house and four RCS thrusters in this house will come a little cutaway opening to see one head of a RCS. |

Today I receive the 1/2 quad house and the four the RCS thrusters.First fit all, little sanding, and than I have done first the quad house. I have chose for really alu zinc color, I found this color most come close, after many photos view. Than the place the decal on it. Tomorrow on with the four the RCS thrusters and one RCS top.

So people this project is also done and I'm very satisfied, the RCS thrusters paint job with color burn as the real one come fine out as result, a little RCS head is there place in the house.There come maybe a new version the education 1/1 RCS cutaway, but that later.     |
