3d printing is just a fancy new name to the additive manufacturing, a concept somewhat old. Also 3d printing is not used usually in some of the additive manufacturing techs, I think is because they aren't mean to the average Joe, they are restricted to the industry. I'm not sure what are we talking about. Is easier and require less machinery to cast the metal than to 3d print it. When you have the liquid metal you can use it directly in a mold made by mars sand (you will need to look for a good one and sieve it), which can be done handmade with basic tools. To 3d print it you need to transform the liquid metal in something usable, that can be powder, wire, or whatever it uses. So: -For casting you only need producing the liquid alloy itself. -For 3d printing you need to produce the liquid alloy, use a machine to made the consumables of the 3d printer, and then you need to use a 3d printer to make whatever. That's two more machines, consuming more time, resources (specially electricity) for a comparable final quality. The only advantage that I can see about 3d printing in this scenario is that you need less skilled workers

Why you think you will need less industrial plant to use 3d print (if you wat to use that word)?? You still need the metallurgical plant to do the metal powder or whatever you are using

3d printing is one of the most expensive methods of manufacturing, and as a rule of thumb it only can replace casting, injection molding or similar process. Also, is additive manufacturing, no 3d printing. There is niche were is the only option or the best alternative because the geometry, but not for everything. You are oversimplifying, there are bigger problems than that, the material structure in additive manufacturing is worse than in the usual manufacturing process, and the dimensional and surface tolerances are far worse, you normally need to do a thermal treatment after the manufacturing process and then machine the part to get it properly done.

Is someone working on this??

If only there were mammals littler than us, and comparable enough. Send laboratory mice, they weigh like 40 grams, you can even make a return mission, when they die from old (in a optimist scenario) or see how they reproduce in mars low gee, and return the mars born ones. Change it to some other mammal if mice ain't good enough. SpaceX could use that red dragon, it would be something that can be done inside a capsule, unlike terrain experiments. Why send humans when there isn't data? Is not like there wasn't animals before humans in the space exploration The problems is the huge amount of everyone dies scenarios here. We can't have people in the ISS the duration of a mars mission without supplies currently, and that's a fact. Life support is the biggest problem, not the rocket, and I don't see spaceX working on that at all, I would like to be wrong

The SpaceX plan has lots of big holes and lots of part that they just are looking to other direction. Is a good article I was worried when national geographic was sold but they seem to be still good As @Nibb31said in other thread, the ITS only has sense to an already established colony, it doesn't has sense in any step by step scenario.

It looks light to me, an early base dependent of the earth. Does anybody know how to download the full one? Forget that

WUT??

http://phys.org/news/2016-10-kepler-caught-hundreds-asteroids.html It turns for example that there isn't rapid spinning Trojans, being icy porous asteroids, and that 20-25% of them are binary asteroids or asteroid-moons. I will explain better: in K2 mision, kepler changed to observe in the ecliptic plane, because now it uses sun radiation pressure to balance itself. That made to the planet hunters a problem because the minor solar system objects are annoying, but some hungarian researches are using the k2 data to study the rotation and other parameters of already known asteroids.

If only we had a minor body close to earth, relatively easy and fast to reach with low gravity, like some natural satellite Colonization without doing any biological research is absurd, if only for the huge cost of making the first settlement in mars, to then discover that (for example) humans body develops illness at an exponential rate in low or no gravity, an effect that we still didn't see because it gets perceptible when you goes 2 years in low gravity. We only have full data of 1g, and a little (the longest stay in space was Valeri Polyakov, 437 days in the MIR) in 0g. Nothing in between, nothing at longer times

http://www.ox.ac.uk/news/science-blog/universe-expanding-accelerating-rate-–-or-it They made an analisys of the latest cataloge of 740 supernova Ia and it only gives a 3 sigma signal. It doesn't seem a strong indication tho, IIRC the supernovas aren't the most important proof of the aceleration.

Seriously? They are still in the materials definition phase? They can't do a real mass estimation I can't get used to reddit PD: Ninjack'ed by @Kryten

If you want homogeneous conditions like temperature and other things, then maybe is better to get a spherical o cylindrical one than in a square one, because the revolution symmetry

That's improved That doesn't happen anymore (at least to me) But yeah I understand. I would try to update in a backup to look how good it goes, without making the hard work. One of my saves went surprisingly well, considering the amount of mods. IIRC the mayor problems was the cash balance (suddenly my regular launch vehicles were unprofitable) and the aero changes.

You will keep this save in the 0.90??? 1.2 is stable and improved lot's and lot's of things. Maybe you already talked about this and I have read it but I read so many different mission reports that it get confusing sometimes

Yes, mostly because the cost in the R&D. And that they are too many parts in reality, can we also have a option to hide the hex cans parts? I rarely use them.

The same that we can disable the life support in the advanced options, is there a way to put another option that we can disable the life support parts also?

Hey, I did that a lot of times, designed by myself, but I still can't into ssto low tech spaceplanes

New indices of this planet. The tilt of the sun could be explained with the nine planet http://www.caltech.edu/news/curious-tilt-sun-traced-undiscovered-planet-52710

It also have a huge benefit of being a process made at room temperature. Give them time, and we'll see. Though I don't really have that big hope with all the nanotech materials, currently they are too difficult to do, and lots of times doesn't work that well in big sizes

Oh c'mon I don't have enough time to play ksp and you make me also want to try this sims, I only played the first one tho.

The question for me is, @Porkjet will you continue working in this mod? (I don't really want to bother you but I think the least we can do is to ask) If not, someone in the mod community should continue it

As an engineer I think you are underestimating the difficulty of this kind of manufacturing process. I hope you are right and I'm wrong

Now with more suns!
