Specification Topics
Top Exam Board Tips
- Always refer to the machine's manual and risk assessment before operation; examiners expect evidence of planning.
- Save design files in the correct format and check compatibility with the fabrication machine; common fault is wrong file type.
- Include a written risk assessment with every practical task as part of your evidence portfolio
- For time-constrained assessments, pre-practice common CAD operations to improve efficiency
- Document each stage of the design and fabrication process with annotated screenshots and photographs
- Familiarise yourself with the specific models of fabrication equipment available in your workshop before the assessment
- Check material-specific settings (e.g., nozzle temperature for PLA vs. ABS, laser power for acrylic) to avoid failed outputs
Common Mistakes to Avoid
- Confusing 2D and 3D design principles when using CAD software, leading to invalid files for 2D fabrication processes.
- Failure to calibrate or level the bed of a 3D printer, causing poor adhesion and print failure.
- Neglecting to de-power the machine before changing bits or cleaning, posing electrical hazards.
- Overlooking ventilation requirements when using materials that emit fumes during laser cutting or 3D printing
- Incorrect scaling of designs in CAD software, leading to dimensional inaccuracies in the final product
- Neglecting machine calibration or bed levelling, resulting in print failures or poor adhesion
- Assuming a fabricated part requires no post-processing, leaving rough edges or support remnants unattended
- Using incompatible file formats between design software and fabrication machine (e.g., confusing STL with G-code)
