How good that Donald (Don 37) mentioned a shrink factor. Now, after the first speechlessness is gone it is time for a bit sobriety. I don't believe in miracles. How to scan winding inner holes? How about two component (copper sulfated tungsten filaments) or multi component parts (ignition plugs)? How much is it to create the often necessary physical properties like mass (flywheels), thermical resilience (valves), tensile strength (piston rods), abrasion characteristics (big end bearing shells), electric conductivity (stators), degree of hardening (piston pins) and dry running capability (bearing rings)? How reliable works a software added spring characteristic (valve springs)? Where to download insulation properties or damping factors? How flexible is printed flexibility? Will wire printers learn to stich frost resistance into printed cast iron? Do you belive in magnetizing apps, a virtual surface quality and emulated noise radiation? ...
Will it be possible to press a bearing in a printed pump impeller? What is a suitable alternative for the gold foil on the Caribbean lettering? Acidic yellow Chinese plastics?
3D-printers are a
mold-breaking innovation but they aren't Packard
replicators.
BTW Howard, I always thought that Mr. Leno is wheel heeled.
