3D Printer Characterization

For this activity, I evaluated the capabilities and limitations of an Ender 3 V2 3D printer.
The purpose was to better understand the design rules that affect successful prints and how
those rules influence future part designs.

Equipment Used

> - Ender 3 V2 - PLA Filament - Cura Slicer

Areas Evaluated

Dimensional Accuracy - Printed parts were measured and compared to their intended dimensions.
- Small variations can occur due to printer calibration and material shrinkage.

Overhangs
- Tested how well the printer could produce features that extend outward without support.
- Larger overhang angles may require support structures.

Bridging

- Evaluated the printer's ability to print across open gaps without support material.
- Print quality decreased as bridge length increased.

Wall Thickness

- Thin walls were tested to determine the minimum reliable printable thickness.
- Extremely thin features can become fragile or fail to print correctly.

Clearance and Tolerances

- Moving and interlocking parts require clearance between components.
- Small gaps may fuse together if tolerances are too tight.

Support Material

- Some geometries required supports to print successfully.
- Support structures improved print success but increased post-processing time.

Areas Evaluated

The Ender 3 V2 was capable of producing accurate and reliable parts when proper design
rules were followed. Features such as overhangs, bridges, wall thickness, and clearances
all influenced print quality and were important considerations during the design process.
What I Learned This exercise helped me understand that successful 3D printing depends not only on the design
itself, but also on the limitations of the manufacturing process. Knowing the printer's
capabilities allows parts to be designed with appropriate tolerances, support requirements,
and geometry for more reliable results.
