01Choosing · 7 min3D printing vs CNC for prototypes
Should your prototype be 3D printed or CNC machined? A plain-English comparison of cost, speed, strength, materials, looks and design freedom, with a simple decision guide.
02Basics · 10 minWhat is rapid prototyping? A plain-English guide
What rapid prototyping means, the main methods (3D printing, CNC machining, urethane casting), how many rounds to expect, and how Shenzhen's prototype shops work.
03Basics · 9 minWhat is vacuum casting? A plain-English guide
How vacuum casting (urethane casting) works, why it's used for 10 to 50 molded-looking parts, what materials and finishes it offers, and how to order it in Shenzhen. Written for first-timers.
04Choosing · 7 minChoosing a prototyping method: 3D printing vs CNC vs urethane casting
A simple comparison of the three main prototyping methods by speed, cost, strength, look and quantity, plus a quick way to pick the right one for each part.
05Cost · 8 min50 parts: casting vs printing vs molding
You need around 50 plastic parts. Should you 3D print them, vacuum cast them, or make a mold? A plain-English comparison of cost, speed, looks and material, with a simple way to compare quotes.
06Basics · 6 minLooks-like vs works-like prototypes
Why most hardware teams build two different kinds of prototype, what each one is for, and when to combine them into a single "looks-like, works-like" build.
