One of the drawbacks with current 3D printing technology is the slow rate at which objects are built up in layers from hot plastic thread. The process of printing objects of any significant size can take hours.
Using a technique similar to airbrushes may speed things up. If the source material is in a fine powdered form instead of a solid thread, and is pushed through the print head (or nozzle in this case) under pressure, then it is simply a matter of determining a way to accrete the plastic into a solid object.

There’s an asymmetry in the data center, and it might be an opportunity for somebody to build a new product line (hint, hint: HP, Dell).
There are plenty of products that consist of a box filled with storage devices – we call them SANs (storage area networks). They’re essentially what allows big data to exist, by packing large amounts of storage into a relatively small space.
In case you haven’t heard, Boeing has been having battery troubles with its new flagship Dreamliner aircraft. The batteries have occasionally been catching fire, and the planes are now grounded until they determine what the issue is.
Hopefully they’ve figured this out already, but there’s one big difference between their on-the-ground tests, and a live flight – the passengers.
I wonder if they’ve tried plugging in a couple of hundred randomly selected laptops into the passenger , and seeing what happens to the electrical system then?
Sounds silly? What if one (or half a dozen) of them has a bad battery, or an electrical short circuit?
This is the final post in the Mars Colony Administrator’s Handbook series. For part one, please see here.
A brief word about science: I’ve avoided discussing planetary science in this series, because it has been covered so well, in so many other places. The traditional vision of a trip to Mars, in the guise of a 1980’s US/USSR joint mission, revolved heavily around the idea of sending a small group of people, for a relatively short period of time, with largely scientific objectives. This is completely different from the various colonization concepts that have circulated in recent years. Regardless of why people go to Mars though, a lot of serious scientific work will be done. The advantages of having a large number of people present, along with a well-equipped laboratory, are immense. We cannot conceive yet of the discoveries that will result. Continue reading →
If computing is ubiquitous, then why do I need a cellphone?
This isn’t a new idea, really. I’ve come across it before in SF novels. Its worth gaming out what the world will look like though. I say “will”, because this scenario looks inevitable. Continue reading →
The Mars colony will be planned in great detail, years in advance. It is impossible for the colony administrators to anticipate everything though. Vast stockpiles of spare parts, and a regular supply chain will help, but certain items will need to be manufactured locally. It is important to remember that issues that are trivial irritants on Earth – a blocked toilet, for example – can become life threatening emergencies in space, or on Mars.
In the previous post, we discussed how legal, jurisdictional and economic issues can effect the future health of the colony. You can also begin at the first post here. Continue reading →
