I'm excited to report that starting this month, I am writing two columns a month for Columbia Journalism Review as a public editor with a focus on CNN. I'll be using my experience as a producer to inform observations about the industry. This is my first post. Look for the next one soon.

2. 3D Printer Electrical Noise and 3D Printer Interference
Modern 3D printers rely on precise stepper motor movements and 3D Printer accurate temperature readings. Electrical noise can disrupt these:
3D Printer Stepper Motor Missed Steps: Electromagnetic interference (EMI) from power supplies, heaters, or poorly shielded wires can cause stepper motors to momentarily "miss" steps, leading to subtle layer shifts or ghosting (ringing) that aren't due to mechanical issues.
3D Printer Inaccurate Temperature Readings: Noise on the thermistor wires can cause fluctuating temperature readings, leading to inconsistent extrusion, blobbing, or even thermal runaway errors if the readings become too erratic.
3D Printer Random Pauses/3D Printer Random Resets: 3D Printer Severe electrical noise or 3D Printer power fluctuations can sometimes cause the 3D printer's mainboard to 3D Printer momentarily freeze, 3D Printer pause, or even 3D Printer reset,…
Student Reflection
While common 3D printing issues like stringing, warping, and layer shifting are widely discussed, there are several less commonly acknowledged or understood problems that can significantly impact print quality and machine longevity. Here are some of those "less known" issues:
Less Known Issues in 3D Printing
1. 3D Printing Filament Moisture Absorption (beyond the obvious "3D Printer popping")
Most users know that wet filament can cause popping sounds and visibly poor prints (stringing, bubbles). However, the subtle effects are often overlooked:
3D Printer Reduced Mechanical Properties: Even slight 3D Printer moisture absorption can significantly degrade the tensile strength, 3D Printer impact resistance, and 3D Printer overall durability of 3D printed parts, especially with 3D Printer hygroscopic filaments like 3D Printer Nylon, 3D Printer PETG, and even 3D Printer PLA.
3D Printer Dimensional Inaccuracy: Moisture can…
3D Printer Uneven Footing/3D Printer Surface: A print surface that isn't perfectly rigid or level can introduce subtle rocking or movement during printing, even if the printer itself feels stable, leading to inconsistent layer height or bed adhesion.
3D Printer Internal Vibrations: Motors, fans, or even poorly tightened bolts within the printer itself can create subtle vibrations that transmit through the frame and affect print quality, especially on machines without robust frames.
6. 3D Printer Aging and 3D Printer Wear of Components
Printers, like any machine, degrade over time, often subtly:
Worn Nozzles: Even without a 3D Printer visible clog, a 3D Printer worn nozzle (enlarged or irregular opening) can lead to inconsistent 3D Printer extrusion, 3D Printer poor line width, and 3D Printer fuzzy prints.
3D Printer Stretched Belts: Over time, drive…
