  1. Fused Deposition Modeling CIM- 2B Gerhard Decker

  2. FDM Known as the second most used type of rapid prototyping. It’s run just like a tattoo artist’s pen, except the nozzle uses heat rather than ink.

  3. FDM is a layer manufacturing method, that requires high strength ABS plastic. Supports are used to help the plastic retain its shape.

  4. Advantages of FDM .High strength in the product .Cost-effective .Waterproof.ABS material .Multiple material colors

  5. Types of FDM Machines Prodigy FDM-2000

  6. Specifications on the FDM 2000 >Build volume- 10”x 10” x 10” >Materials- ABS , Casting wax >Build step size- .005” to .030”

  7. Specifications on the Prodigy • Build Volume- 8”x8”x10” • Materials- ABS, Casting wax • Build step size- .007”, .010”, .013” • Considered 4x as fast as the FDM 2000

  8. Materials used with FDM ABS plastic / Casting Wax ABS Plastic – ABS stands for Acrylonitrile Butadiene Styrene. This product of plastic is made through a polymerization of those monomers. Casting Wax- used in a lot of crafting items, like making rings, glass, etc.

  9. http://www.dynalabcorp.com/technical_info_abs.asp This information chart was taken from the link above. ABS Plastic Product Information Chart Excellent resistance (no attack) to Glycerine, Inorganic Salts, Alkalis, Many Acids, Most Alcohols and Hydrocarbons Limited resistance (moderate attack and suitable for short term use only) to Weak Acids Poor resistance (not recommended for use with) Strong Acids and Solvents, Ketones, Aldehydes, Esters, and some Chlorinated Hydrocarbons Maximum Temperature: 176°F 80°C Minimum Temperature: -4°F -20°C Autoclavable: No Melting Point: 221°F 105°C Tensile Strength: 4,300 psi Hardness: R110 UV Resistance: Poor Translucent Rigid Specific Gravity: 1.04

It’s called “lost Wax” casting, that involves losing the wax when the clay is molded and bronze is added to the clay.

  11. This about wraps up my research upon the FDM process. A video of the process is posted on my wiki space: Gdecker. If you want to see it, it’s there.
