Utilizing Additive Manufacturing technologies/systems/materials, demonstrate the three primary applications of Additive Manufacturing, by 3D-Printing multiple components/versions of your Machinist Hammer design:

1. RAPID PROTOTYPING

   • Print: At least three prototypes:

     • 1) Prototype(s) of the final designs/features of the hammer to test fit/form/function of the final product

     • 2) Prototype(s) of the tooling pattern which will be used for building up the mold for investment casting (see in section 2 below)

     • 3) Prototype(s) of the removeable hammer faces which will be printed via SLS in Nylon & TPU (see in section 3 below)

   • Additive Family: Material Extrusion

     • Technology: Fused Filament Fabrication (FFF)

   • Material: PETG

   • Notes: You are limited to no more than 3 full-size prototypes worth of material. If you think more prototyping is necessary, you must coordinate with your instructor prior to printing any additional parts

2. TOOLING

   • Print: Pattern for building up an investment casting mold

   • Additive Family: Vat Photopolymerization

     • Technology: Stereolithography (SLA)

   • Material: Formlabs Clear Cast Resin v1

   • Notes: You will only be allowed to start after approval

3. PRODUCTS

   • Print:  Two 3D-Printed, removeable hammer faces

   • Additive Family: Powder Bed Fusion (PBF)

     • Technology: Selective Laser Sintering (SLS)

   • Material(s): Nylon 12 White (1 face) & TPU 90A (1 face)

NOTE: The design(s) of your model may have to be modified in order to better fit the scope of the overarching project; this is done intentionally, as your first design(s) are typically not optimized for different manufacturing processes/considerations!
