If someone tells you that PLA is as good as nylon, they aren't listening to you or asking you the right questions. PLA is a great hobbyist material, while nylon is better suited when one is creating engineering grade parts.

If you're programming in Scratch, OpenSCAD should be a breeze for you. (grin)

Going to give myself a crash course, I am a fast learner.Are there any inherent risk from the particles emitted from a 3d printer which can be hazardous? I'm going to set this up near my PC. No USB with this 3d printer; just an sd card slot to read your files.I appreciate your help, alotThank youJeff
