3D Product Post-Processing & Quality 2

Question 1

What is 'color calibration' important for in 3D product visualization and CMF design?

Accepted Answer

Ensuring that colors displayed on a monitor accurately represent actual material colors so CMF specifications translate correctly to production

Answer

Color calibration aligns monitors to a standard (sRGB, DCI-P3) so designers can trust that the colors they see on screen match physical Pantone or RAL standards used in production.

Question 2

What is 'paint adhesion' and how is it ensured on plastic product surfaces?

Accepted Answer

The bonding strength between paint and a surface, ensured through proper surface preparation like sanding, cleaning, and priming

Answer

Paint adhesion on plastic requires proper surface prep — degreasing, light sanding or flame treating, and a compatible primer — to prevent flaking or peeling in use.

Question 3

What is a 'golden sample' or 'master sample' in product manufacturing?

Accepted Answer

A physical reference part approved by the client that defines the exact quality standard all production parts must match

Answer

A golden sample is an approved physical part stored as the definitive quality benchmark — factory QC compares every production part to this physical standard.

Question 4

What is 'destructive testing' in product quality assurance?

Accepted Answer

Testing that evaluates a product's performance by pushing it to failure — sacrificing the sample to measure strength, durability, or safety limits

Answer

Destructive testing measures properties like tensile strength, impact resistance, and fatigue life by intentionally failing samples under controlled, measurable conditions.

Question 5

What is 'poka-yoke' (mistake-proofing) in product design?

Accepted Answer

Designing components so they can only be assembled correctly — like a USB port that only fits one way — preventing assembly errors

Answer

Poka-yoke (from Japanese meaning error-avoidance) uses asymmetric geometry, keying features, and interlock mechanisms to make incorrect assembly physically impossible.
