CompTIA A+ Core 1 (220-1101) — Question 338

A 3-D printer is printing objects that are all unintentionally curved on the bottom. Which of the following should be replaced to best resolve this issue?

Answer options

• A. Filament
• B. Print bed
• C. Corrupt driver
• D. Resin

Correct answer: B

Explanation

The print bed is crucial for ensuring that objects adhere properly during printing, and any irregularities can lead to curvature. While filament, drivers, and resin can affect print quality, the print bed's surface directly impacts the initial layer's formation and stability, making it the most likely cause of the issue.
