+ <p><strong> group assignment:review the safety data sheets for each of your molding and casting materials,
+ then make and compare test casts with each of them <br>
+ individual assignment: design a mold around the stock and tooling that you'll be using, mill it (rough cut + (at least) three-axis finish cut),
+ and use it to cast parts </strong> </p>
+
+ <h4 id="introduction" > <strong> Introduction</strong> </h4>
+ <p><strong> Pattern is the principal tool during the casting process. It may be defined as a model of anything, so constructed that it may be
+used for forming an impression called <i>mould </i> in damp sand or other suitable material. When this mould is filled with molten metal, and the metal is allowed to solidify, it forms
+a reproduction of the pattern and is known as casting. The process of making a pattern is known as pattern making.<br>
+The casting have five stages: (1)pattern making (2) moulding and coremaking (3) melting and casting (4) fettling and (5) testing and inspection. <br> </strong> </p>
+
+ <h4 id="material"> <strong> Pattern Material</strong> </h4>

+<p><strong>Pattern are not made the exact same size as the desired casting for several reasons. Such a pattern would produce castings which are undersize, allowance must therefore be allowed for shrinkage, draft, finish, distortion and rapping.
+Following are the allowance need to consider during patterna making <br>

+ <h4 id="difference" > <strong>Difference between 3D printing and molding</strong> </h4>
+ <p><strong>3D printing is an additive process. It manufactures objects by building them up layer by layer. We can watch this build process as it happens, which is useful when we’re testing a new design. <br> </strong> </p>

+ <div class="oval"><img src="image/a16_1.jpg" width="75%"

+ <br>
+ <p><strong> Injection molding makes use of molds. First, an object’s inverse is carved out of a material that is safe to handle the molten build material (the material the finished object is made of. Then, the molten build material is poured into the mold.
+ Once the material has cooled in the mold, the finished object is ready. <br> </strong> </p>

+ <br>
+ <p><strong> Another difference in them is the way of material is put into the machines, in injection moulding small piece of plastic called “Pellets†are used while in 3D printing “filament†is used. </strong> </p>
