I call bullshit

The truth is that the government funded "scientists" today are pseudo-science government bureaucrat frauds who can't even get a man to the moon without faking it.

Agree. But not because of 3D printing. :)

As for 3D printing in general - there are two things to cosider.

First, it is already much cheaper for making things in small series. Creating mold for injection cost more than 3D printer itself.

Second - it is important branch of tech that have huge importance. Switching from carving things from something to creating things from the scratch by assembling them from perticles from scratch is a huge step in how we create things. Today we do it on relatively large scale using large perticles gluing them together, but next obvious step will be doing that on molecular level, and then on atomic level. So we are only two steps away from that SciFi replicators that could make you anything you need from what you have around, which will completely change all economy, and not in the interests of corporations.

Also you could notice some weirdness in 3D printing development. Modern 3D printers could be perfectly in use since early 70s, when first CNC machines was rolled out. There were all necessary components availabe. Really, affordable FDM 3D printer could be easily rolled out to the public along with first cheap personal computers like Sinclair ZX and Commodore 64. But that was delayed for two decades, and I think it was done intentionally with patents and IP laws. I personally did something similar to 3D printing already in late 80s when I make a CNC mill from old written off flatbed plotter, replacing pen head with mill, carving many hand-drawn layers of object I need from flat plywood or plastic and then glueing them together. Sinclair ZX clone was more than enough for that. So idea was pretty obvious and on the surface for a long time before, but was not used by industry.

Then, recall that first affordable 3D printer was made by enthusiasts (RepRap), not by some corporation. Only because RepRap was opensourced, official enterprises was forced to start production of mass-market 3D printers.

Also, as it happened, recall all that attempts to limit, license or prohibit 3D printing with using something like "they will print guns!!!!111" as reason,

Add to that attempts to forcefully copyright/license things files and other stuff to prevent free exchange of thing files between people. Fortunately all that crap eventually failed, however at the time I heard about few real cases against people who printed "copyrighted content" from games and movies.

Today, more accurate and closer to molecular 3D printing SLA printers are artificially delayed by enormous cost of UV curing resin. And interesting, that it is not resin itself that cost a lot. Resin itself is pretty cheap. It is UV sensitive initiators that are patented and declared as intellectual property that cost absolutely insane money per gram. There is some encouraging news from India chemical manufaturers who just stop care about all that patents and IP crap in the light of nowdays events and began to make affordable UV initiators, but volume is too small yet.

And so on. There are a lot of weird things around 3D prinitnng in general that show obvious resistance against that technology from corporations and TPTB.
