freeamfva: CNC Machining for Prototyping

freeamfva

In simple terms, prototyping is the process of physically building a model or draft of an idea. As engineers, prototyping is a crucial step in the product development process whereby a solid model comes to life and we can touch, see and interact with it. Historically, prototyping has been a lengthy and expensive process, but modern, rapid prototyping allows ideas to take shape in a matter of days.

Traditional vs Rapid Prototyping
Traditionally, prototyping for product development has involved the following steps:

Spending days or weeks designing a product with solid modeling software to create a 3D CAD model and a set of 2D drawings.

Wait weeks or months to receive your machined prototype, usually without much communication
This old style prototyping relied upon sand casting and mock-ups using clay molding, wood, wire and tape. Although claymation movies may be amazing, those antiquated methods are best left to filmmakers. With the invention of CNC machining, 3D printing and rapid prototyping methodology, today’s engineers can fabricate prototypes far faster than ever before.
One concern with rapid prototyping is that 3D printing creates something that looks like the 3D model, and may even be able to move or function as intended, but is dimensionally inaccurate. That’s why 3D printing is an excellent and cost-effectiv option when you’re looking for a prototype for display purposes only.

Rapid prototyping with 3D printing also yields parts that are a different density with different material properties than the final product. This is due to the narrow range of available materials for 3D printing — though the number of materials that can be utilized in additive manufacturing is continuously growing. For instance, metal 3D printed parts are often more porous, which can cause mechanical failures and variable density if not subsequently processed.

CNC rapid prototype machining is the optimal choice when you need an engineering prototype or production prototype that looks, feels and functions as the finished product. And, with digital manufacturing infrastructure, like Fictiv’s platform, you can get instant quotes for CNC machined prototypes with turnaround times as little as a few days.
CNC machined components offer a higher degree of strength and similarity to desired finished product mechanical and material properties than 3D printed parts. Among these desired properties, structural integrity is arguably the most important — structural integrity in this case can be defined as the material’s strength, stiffness and hardness.

With additive manufacturing methods, layer fusion is not always 100% successful, which results in voids, porosity or layer shifting. These inconsistencies in the resulting part can have adverse consequences on the structural integrity of the finished product. With subtractive manufacturing (CNC machining), your prototype is carved from solid, homogenous material stock, which reduces the possibility of geometric discontinuity.
