Jay Leno has a lot of old cars with a lot of obsolete parts. When he needs to replace these parts, he skips the error-prone machinist and goes to his rapid prototyping 3D printer. Simply scan, print and repeat. It’s an amazing way to fabricate parts. The 3D scanner next to Jay creates a digital model of this flanged nut from Jay’s EcoJet supercar. The nut takes 20 minutes to scan and reverse model and 3 hours to print in plastic. One of the hardships of owning an old car is rebuilding rare parts when there are simply no replacements available. My 1907 White Steamer has a feedwater heater, a part that bolts onto the cylinders. It’s made of aluminum, and over the 100-plus years it’s been in use, the metal has become so porous you can see steam and oil seeping through. I thought we could just weld it up. But it’s badly impregnated with oil and can’t be repaired. If we tried, the metal would just come apart. So, rather than have a machinist try to copy the heater and then build it, we decided to redesign the original using our NextEngine 3D scanner and […]
