What is SLA and SLS?

SLA works with polymers and resins, not metals. SLS works with a few polymers, such as nylon and polystyrene, but can also handle metals like steel, titanium, and others. SLA works with liquids, while SLS uses powders that raise safety concerns. Breathing in fine particulates of nickel, for example, can be harmful.

What is the difference between RAD and agile?

Agile model Vs RAD model:Agile projects logically break down the solution into features that are incrementally developed and delivered. The developers using the RAD model focus on developing all the features of an application by first doing it badly and then successively improving the code over time.

Why is manufacturing in China so cheap?

“The reason Chinese products are cheap for American customers is because of China's concentrated supply chain and high efficiency. From start to finish, a factory can mass-produce a product within two weeks,” he said. “Our most basic cables can sell for pennies apiece.”

Can you get rich inventing something?

You can also get more money if your invention turns out to be popular. However, you get less money at first in exchange for that leverage. For instance, a first-time inventor can expect a royalty rate of around 3 percent, and an experienced inventor may see up to 25 percent of the gross profit.

What makes a good prototype design?

Though some typical qualities of a successful prototype are that it: Illustrates the real-world functionality of the product (and whether it needs to be fine-tuned). Shows how the product fits and interacts with other pieces or components (and whether design or dimensional adjustments are required).

How fast is a CNC machine?

How fast are CNC machines? The maximum feed and rapid rates can exceed 2,300 inches per minute (ipm), which is faster than three feet per second. Depending on several factors (part material, tool, path, depth of cut), cutting feeds can exceed 300 ipm, a ballpark for face-milling aluminum.

What is the main characteristic of a prototype?

Qualities Of A Good PrototypePrecision: More precise the prototype, better the response and feedback. Functional: A good prototype performs the basic functions of the actual product (if possible). Improvision: A good prototype is one which can be improvised on with minimum effort.

What are the advantages and disadvantages of prototyping?

Making high-fidelity prototypes can significantly reduce communication costs. And prototyping is more accurate and exquisite. However, the high fidelity means that you need to spend more time and development effort, and it will be more time-consuming when you need to make some adjustments.

What polymers are used in rapid prototyping?

Polydimethylsiloxane (PDMS) has been the mainstay for rapid prototyping in the academic microfluidics community, because of its low cost, robustness and straightforward fabrication, which are particularly advantageous in the exploratory stages of research.

What are the two types of prototyping in Design Thinking?

Prototyping methods are generally divided into two separate categories: low- and high-fidelity prototyping.
