FAQ
What impacts material choice?
Functional requirements such as mechanical strength, thermal resistance, and chemical compatibility are primary drivers. Environmental factors and expected lifespan also heavily influence the decision.
The manufacturing process itself dictates suitable rapid prototyping materials. Cost and desired aesthetics in prototyping are further crucial considerations for product viability.
How does cost influence selection?
Material cost is a significant factor, but it’s essential to consider the total prototype performance cost, including machining, post-processing, and potential rework. Cheaper materials might lead to higher overall project expenses if they fail during testing.
Balancing upfront material expense with desired part properties and longevity is key. Our material selection guide helps navigate these trade-offs effectively, preventing future budget overruns.
Can aesthetics be prioritized?
Absolutely, especially for consumer-facing products or mock-ups where visual appeal and tactile feel are critical. Materials like polished acrylic, anodized aluminum, or specific resins can achieve superior aesthetics in prototyping.
However, aesthetic choices must still align with functional needs to avoid compromising the product’s integrity. We help identify materials that blend visual quality with necessary performance without compromise.
