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.

A new technology allows light to be “designed” into desired forms, potentially making AI and communication technologies faster and more accurate. A KAIST research team has developed an “integrated photonic resonator”—a core component of next-generation optical integrated circuits that process data using light. Interestingly, the research was led by an undergraduate student. This technology is expected to serve as a key foundation for next-generation security technologies such as highspeed data processing and quantum communication.

The resonator developed by the research team of Professor Sangsik Kim from the School of Electrical Engineering, in collaboration with Professor Jae Woong Yoon’s t...

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases...

Researchers have developed a simple and ecofriendly way to use a laser to turn natural leather into flexible and wearable energy devices. The new approach could lay the groundwork for more sustainable wearable electronics. In a paper in Optics Letters, the researchers demonstrate the new technique by creating microsupercapacitors on leather in various patterns, including a tiger, dragon and rabbit.

“Using a laser, we directly write conductive patterns onto vegetable-tanned leather to create microsupercapacitors that can store energy and help smooth electrical signals so that wearable e...
