Molding and Casting

Hi pals?..this is week 9..and its a fun week involving molding and casting of materials..basically what molding and casting entails is similar to the working of 3D printing but here you have to machine a mold/source through: Injections(Sprue,runner,gate,vent,parting line,flashing),Insertion,vacuum,Blowing,Rotational or parts.. in which you cast a material such as:

machineable wax low-temp wax rigid foam gesso alginate gel urethane rubber, plastic silicone PDMS

(polydimethylsiloxane) latex thermoplastic, thermoset polymers calcium sulfate desicant, coagulant, plaster, gypsum, drywall DryStone

Portland cement calcium silicate, aluminum/iron oxide, calcium sulfate Hydro-Stone metal glass ceramic food

Also some materials are enacted to improve versatility/functionality i.e additives fibers (tension, compression, composites) fillers: density, conductivity, flexibility, color, ...

Included also are the various processes observed whenever carrying out Molding and Casting,,these include:

testing mixing deairing pouring ,starting filling vent location curing polymerization cross-linking hydration endothermic, exothermic demolding taper release agents deformation storage shelf life

The relevant softwares to be used include:

ShopBot VCarvePro fab modules image, mold .stl, .png, toolpath, mold tippy.cad, bottom, top, mold, video
Ok here we are,,I personally chose the rotational casting after molding a conical shape in which I used Drystone material in casting...
