  • 2. 

    FDM green sand casting patterns have been tested up to what pressures using ABS-M30 (solid parts)?

    • 100psi

    • 700psi

    • 1700psi

    • 3400psi

    Correct Answer
    A. 1700psi
    Explanation
    FDM green sand casting patterns have been tested up to 1700psi using ABS-M30 (solid parts). This means that the patterns made using this method and material have been subjected to pressures as high as 1700psi without any issues or failures. This information is important for determining the strength and durability of the patterns and ensuring that they can withstand the pressures experienced during the casting process.

    Which one do you like?

    • Dry sand casting

    • Green sand casting

    • Winker sand casting

    • All sand casting

    Correct Answer
    A. Green sand casting
    Explanation
    FDM (Fused Deposition Modeling) is a 3D printing technology that uses a thermoplastic filament. It is best suited for green sand casting, which is a type of sand casting that uses a mixture of sand, clay, and water. This type of sand casting is commonly used in the foundry industry due to its low cost, good dimensional accuracy, and ease of use. FDM technology can be used to create patterns or molds for green sand casting, allowing for the production of complex shapes with high precision.

  • 4. 

    Typical benefits of FDM vs. traditional processes for sand casting patterns include:

    • 50 – 75% time savings

    • 50 – 75% cost savings

    • Enabling rapid design / iteration changes

    • Allows low-volume jobs

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The typical benefits of FDM (Fused Deposition Modeling) compared to traditional processes for sand casting patterns include significant time and cost savings, as well as the ability to quickly make design and iteration changes. FDM also allows for low-volume jobs, making it a versatile and efficient option for sand casting patterns. Therefore, the correct answer is "All of the above."

    For draws greater than one inch (25.4mm) it is recommended to increase the width of all features to larger than what size?

    • 0.1” (2.5mm)

    • 0.5” (13mm)

    • 1.0” (25mm)

    • 2.0” (50mm)

    Correct Answer
    A. 0.5” (13mm)
    Explanation
    For draws greater than one inch (25.4mm), it is recommended to increase the width of all features to larger than 0.5” (13mm).

  • 6. 

    If high compressive forces are used in the molding process, what materials may be best suited?

    • ABS-M30

    • ABS-M30i

    • PC-ABS

    • ULTEM 9085

    Correct Answer
    A. ULTEM 9085
    Explanation
    ULTEM 9085 may be best suited when high compressive forces are used in the molding process. This material is known for its high strength and stiffness, making it capable of withstanding high pressures without deformation or failure. It also has excellent heat resistance and chemical resistance, further enhancing its suitability for applications that require high compressive forces. ABS-M30, ABS-M30i, and PC-ABS may not be as suitable as ULTEM 9085 in terms of their ability to withstand high compressive forces.

    What finishing techniques are acceptable for FDM green sand casting patterns

    • Auto body fillers

    • Hand sanding

    • Finishing Touch Smoothing Station

    • B & C

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the mentioned finishing techniques (auto body fillers, hand sanding, and Finishing Touch Smoothing Station) are acceptable for FDM green sand casting patterns. This means that any of these techniques can be used to achieve the desired finish on the patterns.

    Traditionally green sand casting patterns are manufactured how?

    • Hand carved from wood

    • CNC machined from wood or metal

    • SLA system produce patterns

    • All of the above

    Correct Answer
    A. CNC machined from wood or metal
    Explanation
    Traditionally, green sand casting patterns were manufactured by CNC machining them from wood or metal. This process involves using computer-controlled machines to accurately shape the patterns according to the desired design. CNC machining offers precision and consistency, making it a preferred method for creating intricate patterns. Hand carving from wood is also a traditional method, but it may not provide the same level of accuracy and efficiency as CNC machining. SLA systems, on the other hand, are not traditionally used for manufacturing green sand casting patterns.

    What build style is best suited when mechanical compression of the green sand is used?

    • Custom sparse setting

    • Sparse double-dense

    • Solid

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    All of the above build styles are best suited when mechanical compression of the green sand is used. The custom sparse setting allows for flexibility and customization, the sparse double-dense setting provides a balance between strength and porosity, and the solid setting ensures maximum compression and minimal porosity. Therefore, all three build styles are suitable for mechanical compression of green sand.

    To aid mold release, what top coats are recommended?

    • Primer paint

    • Silcone lubricant

    • Master Foundry – Kote

    • Any standard top coat used for wooden patterns

    • A & B

    • C & D

    Correct Answer
    A. C & D
    Explanation
    The recommended top coats for aiding mold release are Master Foundry – Kote and any standard top coat used for wooden patterns. Both options C and D fulfill this requirement. Primer paint and silicone lubricant are not specifically mentioned as recommended top coats for aiding mold release.
