Plausible Accuracy proposes a question: Labs often require specialized or one-time parts, jigs or other components. Typically they are roughed together, sometimes "straight out of the trash bin".
The post suggests that lab workers are by definition, "Tinkerers", and that they are constantly called upon to solve small and unique experimental construction issues. The idea here is that labs could use 3D print technology to produce the unique one-time-use items they need for experimental construction.
Could this happen? We think so, because most labs will have staff capable of (if not already using) 3D modeling software to design the necessary parts. While many labs, particularly in universities cannot afford their own printer, all they need is a handy 3D printing service and they can proceed.
