A latest YouTube video in content material creator Munro Reside’s ‘Tesla Mannequin Y teardown’ collection has drawn consideration to a relatively uncommon manufacturing follow employed by the electrical automotive producer. Upon inspecting the HVAC (heating, air flow, and air-con) airbox of the automotive, a big injection molded part, the engineer Sandy Munro spots a 3D printed round half – given away by the extraordinarily seen layer strains. Summoning his technical instinct, Sandy attributes the usage of 3D printing to a producing fault within the Mannequin Y manufacturing line, with the FDM fabricated half being a fast repair patch job.

The present should go on
Automobile producers are likely to have a ‘verification of course of’ earlier than commencing mass manufacturing of a mannequin, which means all the particular person elements are manufactured and assembled to make sure it’s potential. The preliminary trial run additionally presents a chance to coach employees on the manufacturing line earlier than any main commitments are made. If something goes improper, the producer has a chance to treatment the issue and fine-tune the method earlier than the beginning of manufacturing.
It’s potential that Tesla missed a flaw within the Mannequin Y’s HVAC unit and began producing the car earlier than it was fastened. When Elon Musk’s engineers lastly caught on to the issue, it could have been too late, with lots of of HVAC models already manufactured and prepared for meeting. At that time, it could have been simpler to only 3D print a lacking part of the car relatively than manage a complete new manufacturing line to mould the massive airboxes.
It’s also potential that Tesla did catch the flaw on the verification stage, and made the selection to hold on with manufacturing anyway, as a substitute utilizing 3D printing to briefly patch up the airbox whereas new molds are produced. This is able to enable the corporate to remain on schedule and ship the primary wave of Mannequin Ys with none hiccups, which it did again in early March of 2020. As of but, there was no official remark from Tesla relating to the 3D printed half.

That is definitely not the primary time an vehicle producer has used 3D printing to supply elements for its automobiles. Earlier this yr, Porsche, recognized for its high-performance sports activities automobiles, introduced the event of its new 3D printed personalised bucket seats. The “bodyform full bucket seat” will initially be restricted to 40 prototypes and will probably be appropriate with Porsche’s 911 and 718 ranges. Across the similar time, APWORKS introduced the 3D printing of a titanium half for the most recent Bugatti Chiron. The 3D printed exhaust tailpipe was designed to be extra light-weight and high-temperature resistant than its predecessor.
