Which material below are easy to be soldered ieSolderability

Which material below are easy to be soldered (ie.Solderability)? Nickel Iron Copper Aluminum Alternate names for Additive Manufacturing do not include: Rapid prototyping 30 printing Desktop manufacturing Serial Production Stereolithograpy (SIA) is an additive process that uses: Printer head UV laser C02 laser Sound waves Which one is NOT the advantage of Stereolithography? Speed of production Strong enough to be machined Can be used as master patterns for injection molding, blow molding Low cost of raw material (Photo-curable resin) and tooling True or False: The tolerance of the Stereolithography process is dependent upon the sharpness of the laser that is used, (circle True or False) True or False: Fused Deposition Modeling requires the construction of a support structure for objects with an overhang, (circle True or False) True or False: The thickness of the layers produced in the FDM process are determined by the extrusion-die diameter (circle True or False)

Solution

23. copper and nickel

copper , tin ,nickel , bronze , brass are those material which can be solder easily.

24.desktop manufacturing and serial production

additive manufacturing include 3D printing , rapid prototype , and selective laser sinetring.SLA ,DMLS,SLM

SLA-stereolithography

SLM-selective laser melting

DMLS-direct metal laser sinetring.

24.UV laser is used in stereolithography ,

UV laser is focused on a vat of photopolymer with the help of CAD/CAM.

25 . low cost of raw material

the cost of photoplymer used is high.
