Planning to get someone responsible for learning about the printer. It's really not just a turn on, and things work, even the
cosplay 3d printer guide. To preserve it, you need someone. You will need to learn how to change the modeling to match what the printer can do (hole sizes, feature sizes, etc (at least in the 2k price range).
With Solidworks, both printers will work perfectly. Your workflow will export sldprt to STL, then introduce the layer heights, speeds, supports, etc. into a slicing program, and then either send it directly to the printer or copy it to the SD card.
To mitigate this, ABS is stronger but more susceptible to warping and requires an enclosed and heated bed. For smoothing bits, acetone post-processing is easy. PLA is easy to print and fairly effective even if someone is brittle. To make them stronger, there are several additives. Nylon takes on water, so printing is harder, but there are many good additives to make very solid and tough nylon prints.
For engineering prototyping, I use a 3d printer. In the past, I have designed them and for the last 5 years or so, I have used several hobbyist-level models. I purchased a mk3 prusa i3 and it works for my needs.
