Question

A function prototype is needed for a hypothetical product. The material must be stronger than 50 MPa. The accuracy requirement is 0.010", and the surface finish requirement is 60 mu inch. Which processes would you recommend and why? A 10 Times 8 Times 5 in^3 rectangular block is being built on an RP machine. The drawing line width is 0.008". Two adjacent lines are drawn with 20% overlap and the layer thickness is 0.005". The drawing speed is 500 inches per second. The elevator positioning time and the sweeping time are 1 second and 2 seconds, respectively. Compare the build times for setting the block at a height equal to 10" and at a height equal to 5".

Explanation / Answer

wire EDM and abrasive water jet machining are the best complimentory methods for good surface finish requirement
