Designing for 3D Printing Limitations

What is the recommended maximum overhang angle before supports are typically needed?

• 30°

• 45°

• 60°

• 90°

What does BRIDGING refers to?

• The process of printing a solid base layer

• Connecting two separate parts after printing

• Adding extra layers to increase strength

• Printing across an open gap without support

1. Why is part orientation important when designing for 3D printing?

• It determines the color of the print

• It ensures the model is hollow

• It influences how much support is needed & how well the layers may bond

• It helps the printer move faster

1. What is a common issue when designing thin walls for 3D printing?

• Walls breaking or not printing correctly

• Warping

• 1. Supports sticking to the model

• Bridging failure

Which of the following is a good reason to use support structures?

• To prevent overhangs from drooping

• To help bridge large gaps

• You can't print liquid material over thin air

• All of the above

6. A tolerance of 0 mm between moving parts ensures a perfect fit.

• True

• False

6. Increasing wall thickness can improve part strength but may increase material usage.

• True

• False

6. Supports should always be used regardless of overhang angles.

• True

• False

Which tool would be the most accurate for taking measurements on a 3D object?

• A ruler

• A tape measure

• The Engineer's Scale

• Calipers

What is the proper name for the "wiggle room" that allows parts to fit together well?

• Just a skosh

• Tolerance

• Get a bigger hammer

• Do these jeans make me look fat?
