3D printing is incredibly precise, but it does differ from traditional manufacturing methods like CNC machining or injection molding in a few ways.

Precision Factors in 3D Printing:

• Layer Resolution – My X1C printer can achieve high-resolution prints with layers as fine as 0.08 mm (80 microns), providing excellent detail.

• Dimensional Accuracy – FDM printing typically has a margin of error of ±0.1 mm to ±0.2 mm, meaning prints are very close to the intended dimensions but might require minor adjustments.

• Surface Finish – While traditional methods produce smooth, polished parts, FDM prints have visible layer lines, though post-processing (sanding, priming, or smoothing) can improve the finish.

• Strength & Material Choice – Injection-molded or machined parts typically use solid materials, while FDM prints have infill, affecting strength. However, high infill percentages and strong filaments (PETG, ABS, carbon fiber-filled) can produce highly durable parts.

When 3D Printing is the Better Choice:

• Rapid Prototyping – Faster and more cost-effective than traditional manufacturing for one-off designs.

• Complex Geometries – Can produce intricate shapes, internal structures, and lightweight components that traditional methods struggle with.

• Customization & Small-Scale Production – Ideal for custom orders where traditional manufacturing would be too expensive for low quantities.

For precise engineering or industrial parts, I fine-tune settings to maximize accuracy and fit, making 3D printing a great alternative in many cases. Let me know if you need high-precision parts, and I’ll adjust settings accordingly!
