How Does It Work?


Your webcam captures real time 3D print images and sends them to The Spaghetti Detective.


The Spaghetti Detective gauges the likelihood of a failure by analyzing the images.


If a possible failure is detected, it will pause the printer, turn off the heaters, and alert you via email or text.


You cancel the print from your phone if failure is confirmed. Save time, money, and your worries.

People Behind The Spaghetti Detective

Kenneth Jiang

Founder, Software & Algorithm Contributor

Kenneth Jiang is a veteran software programmer and 3D printing enthusiast.

He specalizes in building extremely scalable, distributed web backend systems. In his 20 years of experience, he has built, sometimes single-handedly, numerous web applications that scale to millions of users.

While he is fascinated by how much 3D printing empowers makers like himself, he is also stunned by how grossly outdated the 3D printing softwares are. The Spaghetti Detective is his most recent effort at bringing new technologies to 3D printing.

Before The Spaghetti Detective, Kenneth has also built OctoPrint Anywhere and the Slicer Plugin.

What People Are Saying

“ Trying out the @thespaghettispy - it works surprisingly well. Stopped the print after a few centimeters of spaghetti. I'm impressed! I mean I can barely see the issue in that photo… ”

@Mirarkitty on Twitter

“ I'm watching TV, and I get an alert from the detective on my phone. I go look, and it looks the the print is finished. Looking closer, I see that it stopped at 98 %. Looking at the print, I see that the print has been knocked out of alignment. If the print had continued, the last 2% would have been offset. What I find amazing about this, is that the detective could tell that there was a problem without any spaghetti being generated. I didnt realize that the algorithm could detect this failure as well. Well done dev team! ”

Chuck Sommerville on Facebook

“ Keep up the good work. This program is invaluable. Saved me at least 10 messes already.Worth a few false positives not resuming quickly. ”

Justin Wawrzonek on Facebook

“It worked... just a little too well.”
