Successful 3D printer calibration is the fundamental bridge that takes your production quality from “good” to “perfect.” While most enthusiasts focus on temperature, mastering Pressure Advance is the true secret to professional-grade results. This guide serves as a vital technical extension of our 3D Printing Guide Review and complements our deep-dive into Precision 3D Printer Calibration.

What is Pressure Advance in 3D Printing?

Pressure Advance (known as Linear Advance in Marlin firmware) is a predictive technology that manages the internal pressure of the hotend. Because 3D printing filament is slightly elastic, the extruder often pushes too much plastic during deceleration and too little during acceleration. This phenomenon causes bulging corners and uneven surfaces.

Researchers have developed a solar-powered reactor to break down hard-to-recycle forms of plastic waste—such as drink bottles, nylon textiles and polyurethane foams—using acid recovered from old car batteries, and converting it into clean hydrogen fuel and valuable industrial chemicals. The results are reported in the journal Joule.

The reactor, developed by researchers from the University of Cambridge, is powered by the energy from the sun, and could be a cheaper, more su...

Gold cannot form until certain unstable atomic nuclei break apart. Exactly how those nuclear transformations unfold has long been difficult to determine. Now, nuclear physicists at the University of Tennessee (UT) report three discoveries in a single study that clarify important parts of this process. Their findings could help researchers build improved models of the stellar events that create heavy elements and better predict the behavior of exotic atomic nuclei.

Heavy elements such as gold and platinum are forged under extraordinary conditions, including when stars collapse, explode, or collide. These events trigger the rapid neutron capture process (or r-process for short). During this process, an atomic nucleus absorbs neutrons in rapid succession...

Due to our ever-increasing reliance on electronics, researchers are always on the lookout for battery materials with more desirable qualities. Common battery materials, like lithium, can be prone to disadvantages like overheating and material sourcing issues, leading to safety risks and higher costs.

Now, researchers from China have revealed a new battery design that may offer a better alternative to lithium...
