    Common Mistakes

    Common errors to avoid in your coursework

    • Misinterpreting the design brief, leading to missing features or incorrect scale in the 3D model.
    • Creating non-manifold geometry or models with holes, flipped normals, or internal gaps that cause printing failures.
    • Ignoring the capabilities and limitations of the chosen additive manufacturing method, such as minimum feature size or unsupported overhangs.
    • Exporting the design in an incorrect file format or with inappropriate mesh resolution, resulting in poor surface quality or unusable files.
    • Failing to consider post-processing requirements, such as support removal or surface finishing, during the design phase.
    • Neglecting to account for overhangs and bridges, resulting in designs that require excessive supports or are unprintable without modification.
    • Assuming the digital model is automatically print-ready without performing mesh analysis checks for non-manifold edges or inverted normals.
    • Misinterpreting the brief by overlooking constraints such as maximum build volume or functional tolerances, leading to oversized or impractical parts.
    • Students often neglect the specific constraints of additive manufacture, such as overhang angles, support requirements, and minimum feature size, leading to unprintable designs.
    • Another common error is disregarding the design brief's dimensional or functional specifications, resulting in a model that looks correct but does not meet the client's needs.
    • Neglecting to thoroughly read the brief, resulting in designs that miss key dimensions, material specifications, or functional requirements.
    • Designing objects with geometry that cannot be physically realised (e.g., zero-thickness edges, non-manifold meshes, or floating parts) without addressing printability.
    • Assuming any 3D model can be directly printed without considering the need for supports, infill, or appropriate orientation for the specific additive technology.
    • **Misconception 1: This qualification is only about Microsoft products.** **Correction:** While you might touch upon general IT concepts applicable to any system, a core focus of 'Open Systems' is to introduce and build proficiency in open-source alternatives like Linux and LibreOffice, providing a broader skillset beyond proprietary software.
    • **Misconception 2: 'Enterprise' simply means using a computer at work.** **Correction:** 'Enterprise' specifically refers to the more complex, interconnected, and policy-driven IT environment of a business or organisation. It involves understanding shared networks, user accounts, data security protocols, and IT support structures, which differ significantly from typical home computer use.
    • **Misconception 3: Basic computer skills are enough to pass.** **Correction:** While basic computer literacy is a starting point, this qualification requires you to move beyond simple usage. You'll need to understand the 'why' behind IT actions, apply problem-solving skills, and demonstrate practical competence in specific tasks like network configuration, data backup, and security implementation within a professional context.
