It's an emerging technology. It's got a long way to go, and fortunately people (yourself included) are moving the technology forward. But your article makes it sound like the shortcomings of 3d printing exist because the people before you were idiots. That's clearly not the case. If it's so bad, why don't you already have something better in production? I assume the answer is that it's a hard problem, and you are still working on it. Just like everyone else. The difference is that they aren't writing posts about how terrible your current prototype (or whatever you have) is.
