Anytime, Tom.
For the strength, I believe, it is very close to the injection molding tech. But I understand that my own prints might be quite far from perfect yet. I'm at the very beginning of mastering this process. So far I've printed just about a dozen of useful projects, all of them hold very well under the daily stress (nothing very demanding though), but definitely they have their limits. For example, I had some test prints which were done with some deviations from ideal printing parameters. Their major problem was the delamination of horizontal layers. I'm sure that's the primary weak point of all my prints still. So, when I'm constructing something to withstand a stress, I'm always trying to keep primary force vectors parallel to my slices. Industrial grade printers are calibrated at the factory, and professionals are using filaments with precise properties, which they can input into the software to make necessary adjustments for optimal printing conditions, thus preventing any chance of delamination. Finally, 3D printed plastic parts are widely used in very demanding aerospace tech already, that is something, I think.
