STL vs STEP: Which 3D File Format Should You Use?
An STL is a mesh of triangles. A STEP file is exact solid geometry. Here is what that means and which one to send for your part.
FEA vs CFD: What’s the Difference and Which One Do You Need?
FEA tells you whether a part will bend or break. CFD tells you how air or liquid moves around it. Here is how to know which one your design needs.
What Is a Drone Flight Controller and How Does It Work?
The flight controller is the small board that keeps a drone in the air. Here is what it does, how it works, and how to choose one.
Stepper Motor vs Servo Motor for CNC Machines: Which Should You Choose?
Steppers are simple and affordable. Servos are faster and know where they are. Here is how to choose the right motor for your CNC machine.
ESP32 vs Arduino: Which Board Is Right for Your Project?
The ESP32 is faster, cheaper, and has Wi-Fi built in. The Arduino Uno is simpler and more forgiving. Here is how to choose between them.
PLA vs ABS vs PETG: Which 3D Printing Filament Should You Use?
PLA is the easiest to print, ABS handles the most heat, and PETG sits in between. Here is how to choose the right one for your part.
CNC Milling vs CNC Turning: What’s the Difference?
In milling the tool spins and the part stays still. In turning the part spins and the tool stays still. That one difference decides which process fits your part.
