Click on the photo and take a look at the machine. How is the bicycle
frame going to fit inside the printer box?

Notice the spool of plastic "wire" on top of the machine. It takes
two (or more) spools to make CF tubing. One carbon fiber threads on
one or more spools, and the (epoxy?) binder, which presumably is
what's the spool. To the best of my knowledge, there's no such thing
as carbon fiber squeezed through a nozzle or melted on a wire.

Stuck to the front-top-right of the box is a partially obscured photo
of what looks like a bicycle helmet. I think that's what the machine
might be building.

No metal inserts for end points that will be compressed by the axle
nuts.

I'm VERY skeptical and suspect that such a 3D printed frame will fall
apart after when hitting a bump in the road.

Don't most new bikes have plastic frames these days?

Which is unrelated, those being actual products. The
Original Plastic Bike, Inc was only a brochure with slick
photo production but there was no actual product.

OPB may never have sold a bike, but they had at least one store front,
so were (slightly) more than "only a brochure". This was probably
summer of 1972. I was working in a bike shop in Rocky Point, NY (on
Long Island). OPB opened a store in a strip mall a few miles away (on
25A, maybe in Miller Place?) that was closed by the end of the summer.

Some day, plastic bicycles will take over the industry:
https://www.google.com/search?q=plastic+bicycle&tbm=isch
I'm not sure that includes CF (carbon fiber) because of the cost.

How about an (almost) invisible plastic bicycle?

Never mind the garish LED's. It's the clear (invisible) frame that
makes it interesting.
