3D Printing Research
Useful things other people have found out, and references to them.
Tech2C found out the fastest an 8-bit Arduino setup (RAMPS) can print over serial is pretty slow, and over sdcard on a CoreXY the fastest it can plot curves is about 75mm/sec:

CoreXY requires more complex computations than cartesian so these limits don't apply to Mendel or cantilever designs. They're probably fairly applicable for Ultimaker-style gantries tho.
Use cast, not rolled. Trade name for precision cast plates is MIC6:

Bryce Standley found out the fastest an E3D V6 can reliably extrude is about 150mm/sec, faster than that and there is poor layer adhesion due to the filament not spending enough time in the melt zone and not getting hot enough:
A Volcano-style hotend should be able to print faster.
ruiraptor showed that Lion4H's Fang Duct is really good:
3D Printing Nerd suggests most infill is a waste of time and plastic:
Which is all well and good as long as your design doesn't overhang too much or try to print in mid-air.
Angus from Maker's Muse shows printing with multiple infill processes in the same model using S3D could be a good compromise, or just use S3D manual supports properly:

Russ from RWG Research showed that printed PLA bearings work best with silicone spray lubricant, and lasted pretty well even after a year of heavy printing:
List of models and discussion on r/Reprap:
Some people make a carrier which holds PTFE (Teflon) tubes for the bearing surface:
Both Tom and Tech2C have done research and reviews on these:
- Tom shows 6-36V sensors work on 5V: https://www.youtube.com/watch?v=Bov87qlX0Gs
- Tom compares 12 sensors: https://www.youtube.com/watch?v=il9bNWn66BY
- Tech2C explores PNP and NPN sensors: https://www.youtube.com/watch?v=wih4fNkKUCc
