3D Tech­nol­ogy – world’s first 3D printed car

DEMM Engineering & Manufacturing - - CONTENTS -

His­tory was made when the world’s first 3D-printed car drove out of McCormick Place in Chicago.

Dur­ing the six-day In­ter­na­tional Man­u­fac­tur­ing Tech­nol­ogy Show, the ve­hi­cle was printed over 44 hours then as­sem­bled by a team led by Lo­cal Mo­tors with the his­toric first drive set tak­ing place the morn­ing of Satur­day, 13 Septem­ber.

Called the Strati, the ve­hi­cle was printed in one piece us­ing di­rect dig­i­tal man­u­fac­tur­ing, (DDM), which is the first time this method has been used to make a car.

Me­chan­i­cal com­po­nents, such as bat­tery, mo­tor, wiring, and sus­pen­sion are sourced from a va­ri­ety of sup­pli­ers, in­clud­ing Re­nault’s Twizy, a line of elec­tric pow­ered city cars.

John B. Rogers, Jr, CEO of Lo­cal Mo­tors, says: “This brand-new process dis­rupts the man­u­fac­tur­ing sta­tus quo, changes the con­sumer ex­pe­ri­ence and proves that a car can be born in an en­tirely dif­fer­ent way.”

The ve­hi­cle uses the ma­te­rial sci­ence and ad­vanced man­u­fac­tur­ing tech­niques pi­o­neered at the US Depart­ment of En­ergy’s (DOE) Man­u­fac­tur­ing Demon­stra­tion Fa­cil­ity at Oak Ridge Na­tional Lab­o­ra­tory (ORNL).

“This project rep­re­sents the unique op­por­tu­nity DOE’s Na­tional Lab­o­ra­tory Sys­tem of­fers to the in­dus­try, to col­lab­o­rate in an open en­vi­ron­ment to de­liver fast, in­no­va­tive, man­u­fac­tur­ing so­lu­tions,” says Craig Blue, di­rec­tor, Ad­vanced Man­u­fac­tur­ing Pro­gram and Man­u­fac­tur­ing Demon­stra­tion Fa­cil­ity at ORNL.

“Th­ese part­ner­ships are push­ing the en­ve­lope on emerg­ing tech­nolo­gies.”

An­drew Jami­son CEO of Cincin­nati In­cor­po­rated, says: “The de­po­si­tion rate of 40 pounds per hour of car­bon re­in­forced ABS plas­tic and the large size mean that large parts, like a car, can be pro­duced us­ing ad­di­tive tech­nol­ogy.”

The ve­hi­cle proves the vi­a­bil­ity of us­ing sus­tain­able, dig­i­tal man­u­fac­tur­ing so­lu­tions in the au­to­mo­tive in­dus­try. Lo­cal Mo­tors plans to launch pro­duc­tion-level 3D-printed ve­hi­cles that will be avail­able to the pub­lic.
