3D Printed Water Rocketry

Since my last post, quite some time ago, I have been studying up on designing objects for 3D printing. I created some custom hooks that made my wife happy. I fixed my son’s broken toys. And most recently, I adapted an existing water rocket design to fit the parts I had lying around. Great fun ensued.

3D Printers and Air Quality

So lets talk about 3D printers and their fumes. I’ve been heavily into 3D printing for about 2 and a half years, first building a Prusa i3 clone and later buying an Ultimaker 3. One of the things that has always bothered me was the possibility of toxic fumes. About 2 years ago, a study came to light that, yes, indeed, 3D printers do emit things that aren’t good for you. There was a lot of discussion about it around that time, but it seems to have died down.

How to Make 3D Printed Parts Fit Together

One of the great things about 3D printing is that you can print an entire model in one go. The typical example is the fully assembled “print-in-place” ball bearing as shown in the image above. This is printed in one go, no assembly required. However, the tolerances are pretty small which requires a well-tuned 3D printer. In this article, I describe how I tune my machine for perfect fit.
