interesting.  remember that lower receiver that was 3D printed and successfully worked?  That was made out of a durable plastic resin - durable, but still plastic - a receiver 3D printed with this machine would be orders of magnitude superior.

Great technology with lots of potential.  What we need is an inexpensive way to extract pure carbon from a source and produce it in a pure enough form that is usable for this technology and inexpensive to boot.  Even better would be a large but compact carbon production facility suitable for orbit.  Feed it carbonaceous asteroids and print out carbon fiber structural members for all kinds of zero and micro gravity construction projects.

Didn't you mention something else like this a few days/weeks back?  I agree that it would definitely make space exploration/colonization measurably easier.  I only wish I could live long enough to both see it, and participate in it.

It would also make planes lighter and stronger.

A neighbor of mine worked at Boeing, and years ago he worked with his son, fabricating skim boards, out of a honeycomb core, with resin on the outside. They did it in the garage.

Now his son builds racing airplanes from modern lightweight plastic materials. Maybe it is carbon fiber.

The Boeing 787 Dreamliner uses carbon.. The 'composite' design - using mixed materials such as titanium and carbon fibre - is believed to have been a spur for rival Airbus to incorporate carbon fibre in future aircraft. 50 percent of the airplane uses a carbon and plastic mesh.

Love carbon fiber. It's amazing stuff, and, layered properly with kevlar, asbestos (yeah, I know, toxic but totally fireproof) and titanium mesh it makes a light weight, high strength armor. The 24F had that as it's belly armor and the Ka-50 is armored throughout. Still got the duraluminum for the actual airframe (that is a bitch to weld and keeps cracking if you play around with multi G maneuvers), but it really does cut down on weight and increase survivability.

Asbestos isn't a problem so long as it's incorporated into something else entirely and isn't opened up or exposed.  That's why a lot of the asbestos remediation projects that get undertaken are stupid; take, for example, the tiles in the student center at my undergrad uni.  The tiles were glued to the concrete subfloor using an asbestos-containing glue; about 20 years ago the school covered the entire building in plastic and spent one entire summer grinding the tiles and glue up, down to the raw concrete.  The grinding up actually posed more of a risk of asbestos exposure than simply leaving the tiles in place did.  Stupid is as stupid does.

Sealing the asbestos in is called "encapsulation."

There is an entire "sub industry" for removal of "cottage cheese" ceiling textures, that violates laws daily.

They are supposed to test, remove the toxic materials, transport them for disposal in certified waste dumps.

In reality, companies fairly openly do it without the legal procedures.

If given the costs and implications of both methods, most liberal democrats would opt for the cheap, but illegal method.

But when it comes to taxpayer funds, those jurisdictions, such as old schools, will follow the procedures to the letter, and spend many multiples of cost.

of course.  they did the same thing in a number of the older dorm buildings, which was if anything even stupider since that is where people actually live.
