3D Printed Coaster with Scale Physics

This was in my "for you" feed in Google News (they know me, man). A dude 3D printed a roller coaster and installed a motor on the train with a wireless control system that allows it to run with realistic scaled-down physics. It also has a working transfer track and the entire thing is controlled by a web app that he runs on his iPad. This gave me a nerdgasm so I figured some of y'all would enjoy it as well.

3D Printed Model Roller Coaster Accurately Simulates the Real Thing

It's crazy what you can make yourself, at home these days. I wish I had the CAD skills to design and print that stuff.

That's a really cool project, but the final outcome is a little...underwhelming? I 10000% appreciate the engineering it took to build that, but the actual train navigating the track doesn't look like much.

Ugh. One train? Capacity sucks.

Too short, too many trims, etc.

3D printed coaster that you can't ride > RRR

(Just making sure we cover all of the memes.)

Was the printer black?

Not enough trees.

Actually, how has nobody mentioned that this isn’t even a coaster.

You kid, but that's still accurate.

You guys and your jokes but let's be serious for a second. RRR is easily the best Evanescence-playing roller coaster in Orlando.

“I’ve been queuing for 3D Printed Coaster 1 For Ages!”

If you really needed a 3D Printed Coaster 1, you’d already have one.

But seriously (like I should be the one, right?), I’m grateful that there finally is a coaster model that accurately simulates the actual physics and forces of a real roller coaster.

Looks boring.

In all seriousness, I'm curious how many spools of PLA he used to make this. I got into 3d printing last year and one of the first things I looked for was a roller coaster model to print but never got anything to work. This is pretty cool!
