Check out Prusa NEW CORE One L: geni.us/PrusaCOREOneL (affiliate)
The new Prusa CORE One L is here: not much bigger on the outside, but with twice the print volume! After testing it here in the studio, I’ll show you how it performs, what’s new compared to the smaller CORE One, and whether Prusa managed to fix some of the things that previously annoyed me. We’ll take a deep dive into print quality, noise levels, usability, and features like the new active chamber heating, flexible top vent, improved filament path, and Prusa Connect cloud service.
CORRECTION 09/11/25: The print height is 10 mm more than mentioned in the video. The print volume is 300x300x330 mm.

![I made COFFEE 3D Printing FILAMENT
Start your free trial at http://squarespace.com/cnckitchen and use code CNCKITCHEN to get 10% off your first purchase.
I made my own Bio-Composite material for 3D printing by mixing Spent Coffee Grounds with PLA. We’ll talk about why such a material might be useful, what I had to do to make it printable on a regular 3D printer, how the mechanical properties are, and most importantly, how it smells during printing.
