Cover Story
"
The process for producing its Luneburg antennae, each with 6,500
uniquely shaped internal chambers, may be the most advanced use of
additive manufacturing/3D printing in the ADAS and AV space.
" The beauty of 3D printing is not to produce 'unsophisticated widgets' that traditional processes can do
very quickly and cheaply, " Xin explained. " Instead, it's
about producing something like a Luneburg antenna
that's complex and frankly impossible to do with existing
processes. " He said the antenna currently is produced in
batches using a commercial-grade 3D printer, of which
Lunewave owns " several. " One printer can manufacture
1,000 antennae per day. The annual yield of a single
machine printer is about 350,000 antennae, Xin noted.
" The reality is that when we purchase ten 3D
printers, we'll be capable of 3.5 million antennae per
year, " he said. " The scaling for this product is linear;
there is no magic about it. Our lens is easily within
the capability of a 3D printer. "

antennas has been accepted for decades. But the cost
and complexity of manufacture has limited their application to relatively niche high-value but low-volume
use cases, observed Dr. Tom Jellicoe, head of autonomous technology at TTP, an independent technology
company in Cambridge, England.
" What is really exciting about Lunewave is their
combination of innovative manufacture with wide
field-of-view sensors to make extremely high performance, 360-degree automotive systems at a competitive cost point. "
The weight of the antenna, about 10 grams [.35
oz] makes it amenable for mass-production batches.
Lunewave has had " very in-depth " discussions with its
Tier 1 partner and with OEMs to ensure quality and
quantity of the product and process, " Xin noted. ■
