YouTubers are great at driving interest in 3D printers, especially with fancy time-lapses and early hardware reviews. Some of these polished tutorials tend to hide a trend of viral hacks created for ...

The strength of object printed on filament-based 3D printers varies by the plastic used, the G-code used by the printer, the percent infill, and even the temperature the plastic was extruded at.

Here’s a neat trick for your next 3D-printer build or retrofit: a Z-axis sensor using a DIY strain gauge made from SMD resistors. We’re betting it could have plenty of other applications, too.
