I speak as someone who works everyday with 3D printing, or Rapid Prototyping Technologies as we knew it before the press got hold of it.
Firstly,there is currently a WORLD of difference between what is affordible to most of us and what is possible. As some people have said,technology moves ever faster and what was a miracle ten years ago is now quite commonplace.As for how this affects our Miniature world , there are companies, such as Airfix and Games Workshop who use digital sculpting,3D modelling and Rapid Prototyping to produce their masters and injection moulds, but these are the BIG boys in the industry. The investment required is phenomenal, not just in the machinery but in materials and the software(never mind the talent) .It does make commercial sense in the world of mass production and especially in licensing( I do know that a lot of movie-related stuff is digitally created ,one way or another), but in the niche market of ours, I think it will be a few years yet before our sculptors are out of work, if ever. I think the person above who compared this to the production of furniture and clothes has got it right- there will still be a market for individual pieces and small production runs.
There are bureaux which offer a 3D printing service and this is surely the way forward in this regard, but as has been stated, the stepping is the issue with scale models.and until the resolutions get higher, most of the firms in business right now will be safe from the take-over of the MACHINES!!
Where this stuff is used and is saving manufacturers money is in full-size, real-life protoyping and manufacturing.
I work as a professional model maker for a firm of architects and we all thought our jobs were on the line when the photo-real CGI stuff started to get popular, but I still have my job,and my full team. My firm uses both CGI and models- thankfully, there is a more personal connection with a tangible model on a table ,however diagramatic, than even the most hyper-realistic video fly-through.
We were equally worried when we started to use 3D printing, but, as with the introduction of the laser-cutter, it has just become another tool in our arsenal,and our way of working has changed to accommodate it. And when the sculptors start to use digital means, there will still be geniuses, good ones and not so good ones.
Once the resolution issues are sorted,3D printing will be superb, however , for mastering weapons and hardware,as the same master can be used for all scales, subject to a bit of tweaking at the smaller end.
I have to get on with work now ,as the time I have taken to type this is exactly the reason I hesitated to join PF in the first place!
Great topic, but don't believe the hype!
