Which processes produce exceedingly strong parts by adding multiple layers of reinforcement material?

The correct choice is composite molding because this process specifically utilizes layers of reinforcement material such as fibers or fabric, which significantly enhances the strength and structural integrity of the final product. In composite molding, materials like carbon fiber or fiberglass are combined with a resin system, creating strong and lightweight parts suitable for applications where high strength-to-weight ratios are critical. The layering of these materials allows for targeted reinforcement in specific areas, thus producing exceedingly strong parts.

Other processes mentioned, while they have their strengths, do not focus primarily on the addition of multiple layers of reinforcement material in the same way that composite molding does. Binder jetting and selective laser melting are both additive manufacturing methods but generally involve metal or powder materials, which do not inherently provide the same type of layered structural reinforcement as composite materials. Fused deposition modeling, although capable of creating strong parts, primarily uses thermoplastic materials rather than layered reinforcements, making it less effective for targeted strength enhancements compared to composite molding.
