Which of the following p
Which of the following processes illustrates the first commercial RP system?
Charles Hull, who helped found 3D Systems in 1986, developed the first RP process. This process, called stereolithography, builds objects by curing thin consecutive layers of certain ultraviolet light-sensitive liquid resins with a low-power laser.
What is 6D dimension?
Six-dimensional space is any space that has six dimensions, six degrees of freedom, and that needs six pieces of data, or coordinates, to specify a location in this space. There are an infinite number of these, but those of most interest are simpler ones that model some aspect of the environment.
What is the principle of prototype model?
The prototyping model is a systems development method in which a prototype is built, tested and then reworked as necessary until an acceptable outcome is achieved from which the complete system or product can be developed.
What are the 7 phases of STLC?
Software Testing Life Cycle (STLC) – Benefits & Phases
Requirement analysis.
Test planning.
Test case development.
Environment setup.
Test execution.
Test cycle closure.
What is the difference between AM and CNC?
It can be tempting to think of CNC machining as a production process and 3D printing as a prototyping process. After all, CNC is capable of creating high-precision parts from industrial-quality metals, while additive manufacturing has low startup costs and is optimized for on-the-spot, one-off parts.
Which prototype is used by IoT devices?
IoT prototyping is the action of experimenting and implementing design ideas into preliminary versions of a finished product. Essentially, it involves trying out and testing different ways to bring something from the planning phase to reality. In the world of IoT, a prototype could be: A user interface (UI)
What are the 3 main steps in the 3D printing process?
Generally speaking, to print a model through 3D printing needs to go through the following four steps: modeling, slicing, printing, and post-processing.
What are the factors which influences accuracy of RP model?
For example, material shrinkage and control errors are the most significant factors influencing the part accuracy when thermal RP processes are employed, e.g. SLS, MJM, FDM, LENS, etc. On the other hand, curing and control errors are the main factors in RP processes such as SL and SGC.
What are the benefits of additive manufacturing?

What is the classification of rapid tooling?
There are two main types of rapid tooling—direct and indirect—that have different pros and cons. Some product designers will gain the most benefit from a direct rapid tooling process, while others should consider using an indirect method instead.
