I come from an industry that has born the brunt of 'new' technology for many decades now. Printing has undergone so many radical changes from when I entered it in 1968 as a lowly apprentice.
We saw the rise of computers, long before they were affordable, or even available for home use. At first they were seen as a boon then, later on, were blamed for the loss of so many jobs and closures of small companies.
3D printing is being hailed as the next big thing in modelling. What is not being asked is, do I want it in my home. There is much more to this subject than just the printer itself.
You must factor in the cost of a very fast computer, the 3D software, the time it will take you to learn how to use it and, then of course, the 3D printer itself.
For people of my age (60+) there is no desire to make such a large outlay for something that will take so long to master and, will doubtfully give me the results I would crave.
There are undoubtedly areas that will benefit greatly from this technology. Museums are one such area, as was shown in a previous link. Archeology is another field that has become excited about 3D printing, with the medical sciences arena talking about huge advances in replicating vital body replacement parts.
These are all massively funded arenas, who will no doubt use the technology to the max. Where the modelling fraternity is concerned. I personally, cannot envisage even the biggest companies, wanting to make the huge outlay for staff and equipment of the highest quality, in order to embrace such a new technology that is still in its infancy, just for the sake of saying they tried it.
Just because it is here, doesn't mean it will encompass the future of our hobby, unless we want it too. Anyone remember 'Betamax'
