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.

Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.

If utilized on the lunar surface, the material may help build sturdy, nontoxic habitats and tools for future astronauts, capabilities that would be vital to the NASA Artemis missions that aim to establish a long-term human presen...

Additive manufacturing has revolutionized manufacturing by enabling customized, cost-effective products with minimal waste. However, with the majority of 3D printers operating on open-loop systems, they are notoriously prone to failure...

Researchers at Oregon State University have developed a quick-setting, environmentally friendly alternative to concrete they hope can one day be used to rapidly 3D print homes and infrastructure.

Also known as additive manufacturing, 3D printing is already being used to help solve construction challenges such as the global housing crisis that’s emerged as Earth’s population approaches 8.5 billion.

But cement, the binding agent in concrete, accounts for about 8% of the planet’s carbon dioxide emissions, and concrete’s curing time—which can be multiple days—and required structural supports can inhibit progress on construction projects.
