[Joe Barnard] made a solid propellant rocket motor, and as one does in such situations, he put it through its paces on the test stand. The video below is not …read more Continue reading A Look Inside a DIY Rocket Motor
The host of problems to deal with when you’re feeling the need for FDM speed are many and varied, but high on the list is figuring out how to melt …read more Continue reading DIY Spacer Increases FDM Flow Rate for Faster, Better Printing
[Lost in Tech] set out to examine a variety of 3D printing nozzles. Before he got there, though, he found some issues. In particular, he found that his current crop …read more Continue reading Deep Dive into 3D Printing Nozzles
No matter what your position is on internal combustion engines, it’s pretty safe to assume everyone is on the same page regarding wasting fossil fuels: it’s a bad thing. And …read more Continue reading Printed Gas Can Accessories Make Refueling a Little Neater
Most desktop fused deposition modeling (FDM) 3D printers these days use a 0.4 mm nozzle. While many people have tried smaller nozzles to get finer detail and much larger nozzles …read more Continue reading Go Big Or Go Home: 0.6 mm Nozzles are the Future
[Nervous System] does a lot of laser cutting, and [Jesse] shared a fascinating experimental improvement to their laser cutter that consists of a 3D-printed nozzle for cleaner cuts. You can see the results for yourself above, where the difference between the two cuts is striking.
[Jesse]’s modification doesn’t affect the …read more

You’ve got to hand it to [Tom Stanton] – he really thinks outside the box. And potentially outside the atmosphere, to wit: we present his reaction control gas thruster-controlled drone.
Before anyone gets too excited, [Tom] isn’t building drones for use in a vacuum, although we can certainly see a …read more

How worn are your nozzles? It’s a legitimate question, so [Stefan] set out to find out just how bad 3D-printer nozzle wear can get. The answer, as always, is “It depends,” but exploring the issue turns out to be an interesting trip.
Reasoning that the best place to start is …read more
On a fused deposition modeling (FDM) 3D printer, the nozzle size dictates how small a detail you can print. Put simply, you can’t print features smaller than your nozzle for the same reason you’d have trouble signing a check with a paint roller. If the detail is smaller than the diameter of your tool, you’re just going to obliterate it. Those who’ve been around the block a few times with their desktop 3D printer may have seen this come up in practice when their slicer refused to print lines which were thinner than the installed nozzle (0.4mm on the vast …read more

If you’ve ever seen the back end of a military jet, you’ve likely seen variable area nozzles. They’re used to adjust the exhaust flow out of the rear of a jet engine during supersonic flight and while the afterburner is engaged. Commercial aircraft, with the exception of the Concorde, don’t need such fancy hardware since a static exhaust nozzle works well enough for the types of flying they’ll be doing. For much the same reasons, RC aircraft don’t need variable area nozzles either, but it doesn’t keep builders from wanting them.
Which brings us to this utterly gorgeous design by …read more
